The history of California can be divided into: the Native American period; European exploration period from 1542 to 1769; the Spanish colonial period, 1769 to 1821; the Mexican period, 1821 to 1848; and United States statehood, which continues to the present day.
Different tribes of Native Americans lived in the area that is now California for an estimated 13,000 to 15,000 years. Over 100 tribes and bands inhabited the area. Various estimates of the Native American population in California during the pre-European period range from 100,000 to 300,000. California's population held about one-third of all native Americans in what is now the United States.
The native hunter-gatherers practiced various forms of forest gardening and fire-stick farming in the forests, grasslands, mixed woodlands, and wetlands, ensuring that desired food and medicine plants continued to be available. The natives controlled fire on a regional scale to create a low-intensity fire ecology which prevented larger, catastrophic fires and sustained a low-density agriculture in loose rotation; a sort of "wild" permaculture.
California was the name given to a mythical island populated only by beautiful Amazon warriors, as depicted in Greek myths, using gold tools and weapons in the popular early 16th-century romance novel Las Sergas de Esplandián (The Adventures of Esplandián) by Spanish author Garci Rodríguez de Montalvo. This popular Spanish fantasy was printed in several editions with the earliest surviving edition published about 1510. In exploring Baja California the earliest explorers thought the Baja California peninsula was an island and applied the name California to it. Mapmakers started using the name "California" to label the unexplored territory on the North American west coast.
European explorers flying the flags of Spain and of England explored the Pacific Coast of California beginning in the mid-16th century. Francisco de Ulloa explored the west coast of present-day Mexico including the Gulf of California, proving that Baja California was a peninsula, but in spite of his discoveries the myth persisted in European circles that California was an island.
Rumors of fabulously wealthy cities located somewhere along the California coast, as well as a possible Northwest Passage that would provide a much shorter route to the Indies, provided an incentive to explore further.
The first European to explore the California coast was Portuguese explorer and adventurer João Rodrigues Cabrilho (Juan Rodriguez Cabrillo). Cabrillo was commissioned by the Viceroy of New Spain and in 1542 he sailed into what is now San Diego, California. He continued north as far as Pt. Reyes, California.
On November 23, 1542, the little fleet limped back to "San Salvador" (Santa Catalina Island) to overwinter and make repairs. There, around Christmas Eve, Cabrillo stepped out of his boat and splintered his shin when he stumbled on a jagged rock. The injury developed gangrene and he died on 3 January 1543 and was buried there. His second-in-command brought the remainder of the party back to Barra de Navidad, where they arrived 14 April 1543. They had found no wealth, no advanced Indian civilization, no apparent agriculture and no Northwest Passage. As a result California was of little further interest.
The Indians they encountered were living at a bare subsistence level typically located in small rancherias of extended family groups of 100 to 150 people. They had no apparent agriculture, no domesticated animals except dogs, no pottery, and their only tools or weapons were made out of wood, leather, woven baskets and netting, stones and horns. Most lived in rudimentary shelters made of branches and mud with a hole in the center to allow smoke to escape. Some homes were built by digging into the ground two to three feet and then building a brush shelter on top covered with animal skins, Tules and/or mud.
Their clothing was minimal in the summer, with animal skins and coarse woven articles of grass clothing used in winter. Some tribes around Santa Barbara, California and the Channel Islands (California) were using large canoes to fish and trade. It would be found over 200 years later that some Indians in the California delta were using Tule rafts and some Indians on the Northwest coast were using dugout canoes.
Despite the fact that California now grows almost every food crop, the staple foods then used by other American Indian tribes, corn and/or potatoes, would not grow without irrigation in the typically short three- to five-month wet season and nine- to seven-month dry seasons of California (see Mediterranean climate). Indians thrived by catching and eating deer, Tule elk, small game, fish, mollusks, grass seed, berries, insects, edible plants and roots, making it possible to sustain a subsistence hunter-gatherer economy without any agriculture. Without agriculture or migratory herds of animals or fish there are no known ways to support villages, towns or cities—small tribes and extended family groups are the typical hunter-gatherer grouping. A dietary staple for most Indian tribes in interior California was acorns, which were dried, shelled, ground to flour, roasted and soaked in water to leach out their tannin. The holes they ground into large rocks over centuries of use are still visible in many rocks today.
The ground and leached acorn flour was then usually cooked into a tasteless mush. This was a very labor-intensive process nearly always done by the women in the tribe. There are estimates that some Indians might have eaten as much as one ton of acorns in one year. A major advantage of acorns is that they grew wild, could be easily gathered in large quantities, and could be easily stored over a winter for a reliable winter food source. Almost none of these Indian food supplies were in a typical European's diet.
Basket weaving was the highest form of art and utility, and canoes were the peak in man made products. Local trade between Indian tribal groups enabled them to acquire seasonings such as salt, or foodstuffs and other goods that might be rare in certain locales, such as flint for making spear and arrow points. The high and rugged Sierra Nevada mountains located behind the Great Basin Desert east of California, extensive forests and deserts on the north, the rugged and harsh Sonoran Desert and Mojave Desert in the south and the Pacific Ocean on the west effectively isolated California from any easy trade or tribal interactions with Indians on the rest of the continent. The Indians located in the core of California are much different in culture than any other Indian cultures in North America. Cabrillo and his men found that there was essentially nothing for the Spanish to easily exploit in California, and located at the extreme limits of exploration and trade from Spain it would be left essentially unexplored and unsettled for the next 234 years.
In 1565 the Spanish developed a trading route where they took gold and silver from the Americas and traded it for goods and spices from China and other Asian areas. The Spanish centered their trade in the Philippines at first around Cebu, which they had recently conquered, and later in Manila. The trade between the Philippines and Mexico involved using an annual passage of Manila galleon(s). These galleons returning to Mexico from the Philippines went north to about 40 degrees latitude and then turning East they could use the westerly trade winds and currents.
These galleons, after crossing most of the Pacific Ocean, would arrive off the California coast from 60 to over 120 days later somewhere near Cape Mendocino (about 300 miles (480 km) north of San Francisco) at about 40 degrees N. latitude. They then could turn right and sail south down the California coast utilizing the available winds and the south flowing (about 1 mi/hr(1.6(km/h)) California Current. After sailing about 1,500 miles (2,400 km) south on they eventually got to their port in Mexico.
This highly profitable trade with an almost annual trip by one to two ships (number of ships limited by Spanish Crown) down the California coast was continued for over 200 years. The maps and charts were poor and the coast was often shrouded in fog, so most journeys were well off shore. One of the greatest bays on the west coast—San Francisco Bay—escaped discovery for centuries until it was finally discovered by land exploration on November 4, 1769.
The English explorer and privateer Francis Drake sailed along the coast of California in 1579 after capturing two Spanish treasure ships in the Pacific. It is believed that he landed somewhere on the California coast. There his only surviving ship, the Golden Hind, underwent extensive repairs, and needed supplies were accumulated for a trip across the Pacific. Leaving California he followed Ferdinand Magellan on the second recorded circumnavigation of the world and the first English circumnavigation of the world, being gone from 1577 to 1580. It's believed Drake put ashore somewhere north of San Francisco.
The exact location of Drake's landing is still undetermined, but a prominent bay on the California coast, Drakes Bay, bears his name. He claimed the land for England, calling it Nova Albion. The term "Nova Albion" was often used on many European maps to designate territory north of the Spanish settlements. Spanish maps, explorations etc., of this and later eras were generally not published, being regarded as state secrets. As was typical in this era, there were conflicting claims to the same territory, and the Indians who lived there were never consulted.
In 1602, 60 years after Cabrillo, the Spaniard Sebastián Vizcaíno explored California's coastline from San Diego as far north as Monterey Bay. He named San Diego Bay and held the first Christian church service recorded in California on the shores of San Diego Bay. He also put ashore in Monterey, California and made glowing reports of the Monterey bay area as a possible anchorage for ships with land suitable for growing crops. He also provided rudimentary charts of the coastal waters, which were used for nearly 200 years.
The Spanish divided California into two parts, Baja California and Alta California, as provinces of New Spain (Mexico). Baja or lower California consisted of the Baja Peninsula and terminated roughly at San Diego, California where Alta California started. The eastern and northern boundaries of Alta California were very indefinite, as the Spanish claimed essentially everything in the western United States, even though they did occupy hardly any of it for over 200 years.
The first permanent mission in Baja California, Misión de Nuestra Señora de Loreto Conchó, was founded on October 15, 1697, by Jesuit Friar Juan Maria Salvatierra (1648–1717) accompanied by one small boat's crew and six soldiers. After the establishment of Missions in Alta California after 1769, the Spanish treated Baja California and Alta California as a single administrative unit, part of the Viceroyalty of New Spain, with Monterey, California, as its capital.
Nearly all the missions in Baja California were established by members of the Jesuit order supported by a few soldiers. After a power dispute between Charles III of Spain and the Jesuits, the Jesuit colleges were closed and the Jesuits were expelled from Mexico and South America in 1767 and deported back to Spain. After the forcible expulsion of the Jesuit order, most of the missions were taken over by Franciscan and later Dominican friars. Both of these groups were under much more direct control of the Spanish monarchy. Many missions were abandoned in Sonora Mexico and Baja California.
After the conclusion of the Seven Year War between Britain and France and their allies (called the French and Indian War in the British colonies on the East Coast) (1754–1763), France was driven out of North America. Spain and Britain were the only colonial powers left. Britain, as yet, had no Pacific colonies in North America. The Bourbon King Charles III of Spain established missions and other outposts in Alta California out of fear that the territory would be claimed by the British, who not only had 13 colonies on the East Coast, but also several islands in the Caribbean, and had recently taken over Canada from the French.
One of Spain's gains from the Seven Years' War was the French Louisiana Territory which was secretly given to Spain. Another potential colonial power already established in the Pacific was Russia, whose Maritime Fur Trade of mostly sea otter and fur seals was pressing down from Alaska to the Pacific Northwest's lower reaches. These furs could be traded in China for large profits.
The Spanish settlement of Alta California was the last colonization project to expand Spain's vastly over-extended empire in North America, and they tried to do it with minimal cost and support. Approximately half the cost of settling Alta California was borne by donations and half by funds from the Spanish crown. Massive Indian revolts in New Mexico's Pueblo Revolt among the Pueblo Indians of the Rio Grande valley in the 1680s as well as Pima Indian Revolt in 1751 and the ongoing Seri conflicts in Sonora Mexico provided the Franciscan friars with arguments to establish missions with fewer colonial settlers. In particular, the sexual exploitation of Native American women by Spanish soldiers sparked violent reprisals from the Native community and the spread of venereal disease.
The remoteness and isolation of California, the lack of large organized tribes, the lack of agricultural traditions, the absence of any domesticated animals larger than a dog, and a food supply consisting primarily of acorns (unpalatable to most Europeans) meant the missions in California would be very difficult to establish and sustain and made the area unattractive to most potential colonists. A few soldiers and friars financed by the Church and State would form the backbone of the proposed settlement of California.
In 1769, the Spanish Visitor General, José de Gálvez, planned a five part expedition, consisting of three units by sea and two by land, to start settling Alta California. Gaspar de Portolà volunteered to command the expedition. The Catholic Church was represented by Franciscan friar Junípero Serra and his fellow friars. All five detachments of soldiers, friars and future colonists were to meet on the shores of San Diego Bay. The first ship, the San Carlos, sailed from La Paz on January 10, 1769, and the San Antonio sailed on February 15. The San Antonio arrived in San Diego Bay on April 11 and the San Carlos on April 29. The third vessel, the San José, left New Spain later that spring but was lost at sea with no survivors.
The first land party, led by Fernando Rivera y Moncada, left from the Franciscan Mission San Fernando Velicata on March 24, 1769. With Rivera was Father Juan Crespí, famed diarist of the entire expedition. That group arrived in San Diego on May 4. A later expedition led by Portolà, which included Father Junípero Serra, the President of the Missions, along with a combination of missionaries, settlers, and leather-jacket soldiers including José Raimundo Carrillo, left Velicata on May 15, 1769 and arrived in San Diego on June 29.
They took with them about 46 mules, 200 cows and 140 horses—all that could be spared by the poor Baja Missions. Fernando de Rivera was appointed to command the lead party that would scout out a land route and blaze a trail to San Diego. Food was short, and the Indians accompanying them were expected to forage for most of what they needed. Many Indian neophytes died along the way; even more deserted. The two groups traveling from Lower California on foot had to cross about 300 miles (480 km) of the very dry and rugged Baja Peninsula.
The part of the expedition that took place over land took about 40–51 days to get to San Diego. The contingent coming by sea encountered the south flowing California Current and strong head winds, and were still straggling in three months after they set sail. After their arduous journeys, most of the men aboard the ships were ill, chiefly from scurvy, and many had died. Out of a total of about 219 men who had left Baja California, little more than 100 survived. The survivors established the Presidio of San Diego on May 14, 1769. Mission San Diego de Alcala was established on July 16, 1769. As the first of the presidios and Spanish missions in California, they provided the base of operations for the Spanish colonization of Alta California (present-day California).
On July 14, 1769, an expedition was dispatched from San Diego to find the port of Monterey. Not recognizing the Monterey Bay from the description written by Sebastián Vizcaíno almost 200 years prior, the expedition traveled beyond it to what is now the San Francisco, California area. The exploration party, led by Don Gaspar de Portolà, arrived on November 2, 1769, at San Francisco Bay., One of the greatest ports on the west coast of America had finally been discovered by land. The expedition returned to San Diego on January 24, 1770. The Presidio and Mission of San Carlos de Borromeo de Monterey were established on June 3, 1770, by Portola, Serra, and Crespi.
Without any agricultural crops or experience gathering, preparing and eating the ground acorns and grass seeds the Indians subsisted on for much of the year, the shortage of food at San Diego became extremely critical during the first few months of 1770. They subsisted by eating some of their cattle, wild geese, fish, and other food exchanged with the Indians for clothing, but the ravages of scurvy continued because there was then no understanding of the cause or cure of scurvy (a deficiency of vitamin C in fresh food). A small quantity of corn they had planted grew well, only to be eaten by birds. Portolá sent Captain Rivera and a small detachment of about 40 men south to the Baja California missions in February to obtain more cattle and a pack-train of supplies.
Fewer mouths to feed temporarily eased the drain on San Diego's scant provisions, but within weeks, acute hunger and increased sickness (scurvy) again threatened to force abandonment of the San Diego "Mission". Portolá finally decided that if no relief ship arrived by March 19, 1770 they would leave to return to the "New Spain" missions on the Baja Peninsula the next morning "because there were not enough provisions to wait longer and the men had not come to perish from hunger." At three o'clock in the afternoon on March 19, 1770, as if by a miracle, the sails of the sailing ship San Antonio, loaded with relief supplies, were discernible on the horizon. The Spanish settlement of Alta California would continue.
Juan Bautista de Anza, leading an exploratory expedition on January 8, 1774, with 3 padres, 20 soldiers, 11 servants, 35 mules, 65 cattle, and 140 horses set forth from Tubac south of present day Tucson, Arizona. They went to across the Sonoran desert to California from Mexico by swinging south of the Gila River to avoid Apache attacks until they hit the Colorado River at the Yuma Crossing—about the only way across the Colorado River. The friendly Quechan (Yuma) Indians (2-3,000) he encountered there were growing most of their food, using irrigation systems, and had already imported pottery, horses, wheat and a few other crops from New Mexico.
After crossing the Colorado to avoid the impassible Algodones Dunes west of Yuma, Arizona, they followed the river about 50 miles (80 km) south (to about the Arizona's southwest corner on the Colorado River) before turning northwest to about today's Mexicali, Mexico and then turning north through today's Imperial Valley and then northwest again before reaching Mission San Gabriel Arcángel near the future city of Los Angeles, California. It took Anza about 74 days to do this initial reconnaissance trip to establish a land route into California. On his return trip he went down the Gila River until hitting the Santa Cruz River (Arizona) and continuing on to Tubac. The return trip only took 23 days, and he encountered several peaceful and populous agricultural tribes with irrigation systems located along the Gila River.
In Anza's second trip (1775–1776) he returned to California with 240 friars, soldiers and colonists with their families. They took 695 horses and mules, 385 Texas Longhorn bulls and cows with them. The approximately 200 surviving cattle and an unknown number of horses (many of each were lost or eaten along the way) started the cattle and horse raising industry in California. In California the cattle and horses had few enemies and plentiful grass in all but drought years. They essentially grew and multiplied as feral animals, doubling roughly every two years. The party started from Tubac, Arizona, on October 22, 1775 and arrived at San Francisco Bay on March 28, 1776. There they established the Presidio of San Francisco, followed by a mission, Mission San Francisco de Asís (Mission Dolores) --the future city of San Francisco.
In 1780, the Spanish established two combination missions and pueblos at the Yuma Crossing: Mission San Pedro y San Pablo de Bicuñer and Mission Puerto de Purísima Concepción. Both these pueblos and missions were on the California side of the Colorado River but were administered by the Arizona authorities. On July 17–18, 1781 the Yuma (Quechan) Indians, in a dispute with the Spanish, destroyed both missions and pueblos—killing 103 soldiers, colonists, and Friars and capturing about 80 prisoners, mostly women and children. In four well-supported punitive expeditions in 1782 and 1783 against the Quechans, the Spanish managed to gather their dead and ransom nearly all the prisoners, but failed to re-open the Anza Trail. The Yuma Crossing was closed for Spanish traffic and it would stay closed until about 1846. California was nearly isolated again from land based travel. About the only way into California from Mexico would now be a 40-60 day voyage by sea. The average of 2.5 ships per year from 1769 to 1824 meant that additional colonists coming to Alta California were few and far between.
Eventually, 21 California Missions were established along the California coast from San Diego to San Francisco—about 500 miles (800 km) up the coast. The missions were nearly all located within 30 miles (48 km) of the coast and almost no exploration or settlements were made in the Central Valley (California) or the Sierra Nevada (California). The only expeditions anywhere close to the Central Valley and Sierras were the rare forays by soldiers undertaken to recover runaway Indians who had escaped from the Missions. The "settled" territory of about 15,000 square miles (40,000 km2) was about 10% of California's eventual 156,000 square miles (400,000 km2) territory.
In 1786, Jean-François de Galaup, comte de La Pérouse led a group of scientists and artists who compiled an account of the Californian mission system, the land, and the people. Traders, whalers, and scientific missions followed in the next decades.
The California Missions, after they were all established, were located about one day's horseback ride apart for easier communication and linked by the El Camino Real trail. These Missions were typically manned by two to three friars and three to ten soldiers. Virtually all the physical work was done by Indians convinced to or coerced into joining the missions. The padres provided instructions for making adobe bricks, building mission buildings, planting fields, digging irrigation ditches, growing new grains and vegetables, herding cattle and horses, singing, speaking Spanish, and understanding the Catholic faith—all that was thought to be necessary to bring the Indians to be able to support themselves and their new church.
The soldiers supervised the construction of the Presidios (forts) and were responsible for keeping order and preventing and/or capturing runaway Indians that tried to leave the missions. Nearly all of the Indians adjoining the missions were induced to join the various missions built in California. Once the Indians had joined the mission, if they tried to leave, soldiers were sent out to retrieve them. In the 1830s, Richard Henry Dana, Jr. observed that Indians were regarded and treated as slaves by the Spanish-speaking Californios.
The missions eventually claimed about 1/6 of the available land in California or roughly 1,000,000 acres (4,047 km2) of land per mission. The rest of the land was considered the property of the Spanish monarchy. To encourage settlement of the territory, large land grants were given to retired soldiers and colonists. Most grants were virtually free and typically went to friends and relatives in the California government. A few foreign colonists were accepted if they accepted Spanish citizenship and joined the Catholic Faith. The Mexican Inquisition was still in nearly full force and forbade Protestants living in Mexican controlled territory. In the Spanish colonial period many of these grants were later turned into Ranchos.
Spain made about 30 of these large grants, nearly all several square leagues (1 Spanish league = 2.6 miles (4.2 km)) each in size. The total land granted to settlers in the Spanish colonial era was about 800,000 acres (3,237 km2) or about 35,000 acres (142 km2) each. The few owners of these large ranchos patterned themselves after the landed gentry in Spain and were devoted to keeping themselves living in a grand style. The rest of the population they expected to support them. Their mostly unpaid workers were nearly all Spanish trained Indians or peons that had learned how to ride horses and raise some crops. The majority of the ranch hands were paid with room and board, rough clothing, rough housing and no salary.
The main products of these ranchos were cattle, horses and sheep, most of which lived virtually wild. The cattle were mostly killed for fresh meat, as well as hides and tallow (fat) which could be traded or sold for money or goods. As the cattle herds increased there came a time when nearly everything that could be made of leather was—doors, window coverings, stools, chaps, leggings, vests lariats (riata)s, saddles, boots etc. Since there was no refrigeration then, often a cow was killed for the day's fresh meat and the hide and tallow salvaged for sale later. After taking the cattle's hide and tallow their carcasses were left to rot or feed the California grizzly bears which roamed wild in California at that time, or to feed the packs of dogs that typically lived at each rancho.
A series of four presidios, or "royal forts", each manned by 10 to 100 men, were built by Spain in Alta California. California installations were established in San Diego (El Presidio Real de San Diego) founded in 1769, in San Francisco (El Presidio Real de San Francisco) founded in 1776, and in Santa Barbara (El Presidio Real de Santa Bárbara) founded in 1782. After the Spanish colonial era the Presidio of Sonoma in Sonoma, California was founded in 1834.)
To support the presidios and the missions, half a dozen towns (called pueblos) were established in California. The pueblos of Los Angeles, San Diego, San Francisco, Santa Barbara, Villa de Branciforte (later abandoned before later becoming Santa Cruz, California) and the pueblo of San Jose, California were all established to support the Missions and presidios in California. These were the only towns (pueblos) in California.
In 1821, Mexico gained its independence from Spain. Alta California became one of the three interior provinces in the First Mexican Empire north of the Rio Grande, along with Texas and New Mexico. The Franciscans Missionaries and soldiers in Alta California had not been paid in about seven years in 1821. The capital of the Mexican government in Alta California was Monterey, California (originally called San Carlos de Monterrey).
Mexico, after independence, continued to be unstable with about 40 changes of government, in the 27 years prior to 1848—an average government duration was 7.9 months. In Alta California Mexico inherited a large, sparsely settled, poor, backwater province paying little or no net tax revenue to the Mexican State. In addition, Alta California had a rapidly declining Mission system as the Mission Indian population in Alta California continued to rapidly decrease.
The number of Alta California settlers, always a small minority of total population, slowly increased mostly by more births than deaths in the Californio population in California. After the closure of the de Anza Trail across the Colorado River in 1781 immigration from Mexico was nearly all by ships. California continued to be a small, nearly isolated province.
Even before Mexico gained control of Alta California the onerous Spanish rules against trading with foreigners began to break down as the declining Spanish fleet couldn’t enforce their no-trading policies. The settlers, and their descendents (who became known as Californios), had essentially no industries or manufacturing capabilities, so they were eager to trade for new commodities, finished goods, luxury goods, and other merchandise. The Mexican government abolished the no trade with foreign ships policy and soon regular trading trips were being made.
In addition, a number of Europeans and Americans became naturalized Mexican citizens and settled in early California. Some of those became rancheros and traders in the later years of the Mexican period, such as Abel Stearns.
Cattle hides and tallow provided the necessary trade articles for a mutually beneficial trade. The first American, English, and Russian trading ships first appeared in California a few years before 1820. The classic book Two Years Before the Mast by Richard Henry Dana, Jr. provides a good first hand account of this trade. From 1825 to 1848 the average number of ships traveling to California increased to about 25 ships per year—a large increase from the average of 2.5 ships per year from 1769 to 1824.
The port of entry for trading purposes was Monterey, California where custom duties of up to 100% (also called tariffs) were applied. These high duties gave rise to much bribery and smuggling, as avoiding the tariffs made more money for the ship owners and made the goods less costly to the customers. Essentially all the cost of the California government (what little there was) was paid for by these tariffs. In this they were much like the United States in 1850, where about 89% of the revenue of its federal government came from import tariffs, although at an average rate of about 20%.
So many Mission Indians died from exposure to harsh conditions and diseases like measles, diphtheria, smallpox, syphilis, etc. that at times raids were undertaken to new villages in the interior to supplement the supply of Indian women. This increase in deaths was accompanied by a very low live birth rate among the surviving Indian population. As reported by Krell, as of December 31, 1832, the mission Franciscan padres had performed a combined total of 87,787 baptisms and 24,529 marriages, and recorded 63,789 deaths.
If Krell's numbers are to be believed (others have slightly different numbers) the Mission Indian population had declined from a peak of about 87,000 in about 1800 to about 14,000 in 1832 and continued to decline. The Missions were becoming ever more strained as the number of Indian converts drastically declined and the deaths greatly exceeded the births. The ratio of Indian births to deaths is believed to have been less than 0.5 Indian births per death.
The Missions, as originally envisioned, were to last only about 10 years before being converted to regular parishes. When the California Missions were abolished in 1834 some missions had existed over 66 years but the Mission Indians were still not self-sufficient, proficient in Spanish, or wholly Catholic. Taking people from a hunter-gatherer type existence to an educated, agricultural-based existence was much more difficult than the missionaries had originally thought. The severe and continuing decline in Mission Indian populations exacerbated this problem. In 1834 Mexico, in response to demands that the Catholic Church give up much of the Mission property, started the process of secularizing the Franciscan run missions. Mission San Juan Capistrano was the very first to feel the effects of this legislation the following year when, on August 9, 1834 Governor Figueroa issued his "Decree of Confiscation." 
Nine other Missions quickly followed, with six more in 1835; San Buenaventura and San Francisco de Asís were among the last to succumb, in June and December 1836, respectively. The Franciscans soon thereafter abandoned most of the missions, taking with them almost everything of value they could, after which the locals typically plundered the mission buildings for construction materials, furniture, etc. or the Mission buildings were sold off to serve other uses.
In spite of this neglect, the Indian towns at San Juan Capistrano, San Dieguito, and Las Flores did continue on for some time under a provision in Governor Echeandía's 1826 Proclamation that allowed for the partial conversion of missions to new pueblos. After the secularizing of the Missions, many of the surviving Mission Indians switched from being unpaid workers for the missions to unpaid laborers and vaqueros (cowboys) of the about 500 large Californio owned ranchos.
Before Alta California became a part of the Mexican state, about 30 Spanish land grants had already been deeded in all of Alta California to a few friends and family of the Alta California Governors. The 1824 Mexican Colony Law established rules for petitioning for land grants in California; and by 1828, the rules for establishing land grants were codified in the Mexican Reglamento (Regulation). The Acts sought to break the monopoly of the Catholic Franciscan missions, while paving the way for additional settlers to California by making land grants easier to obtain.
When the Missions were secularized, the Mission property and cattle were supposed to be mostly allocated to the Missions Indians. In practice, nearly all Mission property and livestock were taken over by the about 455 large ranchos granted by the governors—mostly to friends and family at low or no cost. The rancho owners claimed about 8,600,000 acres (35,000 km2) averaging about 18,900 acres (76 km2) each. This land was nearly all distributed on former mission land within about 30 miles (48 km) of the coast.
The Mexican land grants were provisional until settled and worked on for five years, and often had very indefinite boundaries and sometimes conflicting ownership claims. The boundaries of each rancho were almost never surveyed, and marked, and often depended on local landmarks that often changed over time. Since the government depended on import tariffs for its income, there was virtually no property tax—the property tax when introduced with U.S. statehood was a big shock. The grantee could not subdivide, or rent out, the land without approval.
The rancho owners tried to live in a grand manner, and the result was similar to a European feudal aristocracy. For these few rancho owners and families, this was California's Golden Age; for the vast majority it was not golden. Much of the agriculture, vineyards, and orchards established by the Missions were allowed to deteriorate as the rapidly declining Mission Indian population required less food, and the Missionaries and soldiers supporting the Missions disappeared. The new Ranchos and slowly increasing Pueblos mostly only grew enough food to eat and to trade with the occasional trading ship or whaler that put into a California port to trade, get fresh water, replenish their firewood and obtain fresh vegetables.
The main products of these ranchos were cow hides (called California greenbacks) and tallow (rendered fat for making candles and soap) that were traded for other finished goods and merchandise. This hide-and-tallow trade was mainly carried on by Boston-based ships that traveled 14,000 miles (23,000 km) to 18,000 miles (29,000 km) around Cape Horn to bring finished goods and merchandise to trade with the Californio Ranchos for their hides and tallow. The cattle and horses that provided the hides and tallow essentially grew wild.
By 1845, the province of Alta California had a non-native population of about 1,500 Spanish and Latin American-born adult men along with about 6,500 women and their native-born children (who became the Californios). These Spanish-speakers lived mostly in the southern half of the state from San Diego north to Santa Barbara. There were also around 1300 American immigrants and 500 European immigrants from a wide variety of backgrounds. Nearly all of these were adult males and a majority lived in central and northern California from Monterey north to Sonoma and east to the Sierra Nevada foothills.
A large non-coastal land grant was given to John Sutter who, in 1839, settled a large land grant close to the future city of Sacramento, California, which he called "New Helvetia" (New Switzerland). There, he built an extensive fort equipped with much of the armament from Fort Ross—bought from the Russians on credit when they abandoned that fort. Sutter's Fort was the first non-Native American community in the California Central Valley. Sutter's Fort, from 1839 to about 1848, was a major agricultural and trade colony in California, often welcoming and assisting California Trail travelers to California. Most of the settlers at, or near, Sutter's Fort were new immigrants from the United States.
Hostilities between the U.S. and Mexico were inspired in part by territorial disputes between Mexico and the Republic of Texas, and later by the American annexation of Texas in 1846. Several battles between U.S. and Mexican troops led the United States Congress to issue a declaration of war against Mexico on May 13, 1846; the Mexican–American War had begun. Word of the conflict reached Alta California about a month later.
The main forces available to the United States in California were the bluejacket sailors and U.S. Marines on board the ships of the Pacific Squadron. Speculating that war with Mexico over Texas and other land was very possible, the U.S. Navy had sent several additional naval vessels to the Pacific in 1845 to protect U.S. interests there. It took about 200 days, on average, for ships to travel the greater than 17,000-mile (27,000 km) trip from the East coast around Cape Horn of South America to California.
Initially as the war with Mexico started there were five vessels in the U.S. Navy's Pacific Squadron near California. In 1846 and 1847 this was increased to 13 Navy vessels—over half the U.S. Navy's available ships. The only other U.S. military force then in California was the about 30 military topographers etc. and 30 mountain men, guides, hunters, etc. in Captain John C. Frémont's United States Army Corps of Topographical Engineers exploratory force. They were exiting California on their way to what is now Oregon when they got word in early June 1846 that war was imminent and a revolt had already started in Sonoma, California. Hearing rumors of possible Californio military action against the newly arrived settlers in California (this had already happened in 1840), some settlers decided to neutralize the small Californio garrison at Sonoma, California. On June 15, 1846, some thirty settlers, mostly American citizens, staged a revolt and seized the small Californio garrison, in Sonoma, without firing a shot and declared the new California Republic government. On hearing of this revolt, Fremont and his exploratory force returned to California. The "republic" never exercised any real authority and only lasted 26 days before accepting U.S. government control.
The former fleet surgeon William M. Wood and John Parrot, the American Consul of Mazatlán, arrived in Guadalajara, Mexico on May 10, 1846. There they heard word of the on-going hostilities between the U.S. and Mexico forces and sent a message by special courier back to Commodore (Rear Admiral) John D. Sloat, commander of the Pacific Squadron then visiting Mazatlán Mexico. On May 17, 1846, this courier's messages informed Commodore Sloat that hostilities between the U.S. and Mexico had commenced.
Commodore (Rear Admiral) John D. Sloat and four of his vessels were then at anchor in the harbor of Mazatlán, Mexico. On hearing the news, Commodore Sloat dispatched his flagship, the Frigate Savannah, and the sloop Levant (1837) to Monterey harbor, where they arrived on July 2, 1846. They joined the sloop Cyane which was already there. There were U.S. fears that the British might try to annex California to satisfy British creditors. The British Pacific Station's squadron of ships off California were stronger in ships, guns, and men than the American ships. Apparently the British never had any orders on whether to interfere or not if hostilities broke out between The Californios and the United States and requesting new orders would have taken from one and a half and two years to get a message to England and back.
Initially there was little resistance from anyone in California as they replaced the dysfunctional and ineffective Mexican government which had already been replaced by the Californios. The Mexican government by 1846 had already had 40 presidents in the first 24 years of its existence. Most new settlers and Californios were neutral or actively supported the revolt. John A. Sutter and his men and supplies at Sutter's Fort joined the revolt. They raised the "Bear Flag" of the California Republic over Sonoma. The republic was in existence scarcely more than a week before Frémont returned and took over on June 23 from William B. Ide the leader of the Bear Flag Revolt. The California state flag of today is based on this original Bear Flag and still contains the words "California Republic."
In 1846, the U.S. Navy was under orders to take over all California ports in the event of war. There were about 400–500 U.S. Marines and U.S. Navy bluejacket sailors available for possible land action on the Pacific Squadron's ships. Hearing word of the Bear Flag Revolt in Sonoma, California, and the arrival of the large British 2,600-ton, 600-man man-of-war HMS Collingwood flagship under Sir George S. Seymour, outside Monterey Harbor, Commodore Sloat was finally stirred to action. On July 7, 1846, seven weeks after war had been declared, Sloat instructed the captains of the ships USS Savannah and sloops Cyane and Levant of the Pacific Squadron in Monterey Bay to occupy Monterey, California—the Alta California capital. Fifty American marines and about 100 bluejacket sailors landed and captured the city without incident—the few Californio troops formerly there having already evacuated the city. They raised the flag of the United States without firing a shot. The only shots fired were a 21-gun salute to the new U.S. flag fired by each of the U.S. Navy ships in the harbor. The British ships observed but took no action.
The abandoned Presidio and Mission San Francisco de Asís (Mission Dolores) at San Francisco, then called Yerba Buena, was occupied without firing a shot on July 9, 1846 by U.S. Marines and U.S. Navy sailors from the sloop USS Portsmouth. Militia Captain Thomas Fallon led a small force of about 22 men from Santa Cruz, California and captured the small town of Pueblo de San Jose without bloodshed on July 11. 1846. Fallon received an American flag from Commodore John D. Sloat, and raised it over the pueblo on July 14. On 1July 15, 1846, Commodore (Rear Admiral) Sloat transferred his command of the Pacific Squadron to Commodore Robert F. Stockton when Stockton's ship, the frigate USS Congress, arrived from the Sandwich Islands (Hawaii).
Stockton, a much more aggressive leader, asked Fremont to form a joint force of Fremont's soldiers, scouts, guides etc. and a volunteer militia—many who were former Bear Flag Revolters. This unit, called the California Battalion, was mustered into U.S. service and were paid regular army wages. On July 19, Frémont's newly formed "California Battalion" swelled to about 160 men. These men included Fremont's 30 topographical men and their 30 scouts and hunters, U.S. Marine Lieutenant Archibald H. Gillespie, a U.S. Navy officer to handle their two cannons, a company of Indians trained by Sutter and many other permanent California settlers from several different countries as well as American settlers. The California Battalion members were used mainly to garrison and keep order in the rapidly surrendering California towns.
The Navy went down the coast from San Francisco, occupying ports without resistance as they went. The small pueblo (town) of San Diego surrendered 29 July 1846 without a shot being fired. The small pueblo (town) of Santa Barbara surrendered without a shot being fired in August 1846. On August 13, 1846, a joint force of U.S. Marines, bluejacket sailors and parts of Frémont's California Battalion carried by the USS Cyane entered Los Angeles, California with flags flying and band playing. Captain Archibald H. Gillespie, (Frémont's second in command), with an inadequate force of 40 to 50 men, were left to occupy and keep order in the largest town (about 3,500) in Alta California—Los Angeles.
On August 13, 1846, a joint force of U.S. Marines, bluejacket sailors and parts of Frémont's California Battalion carried by the USS Cyane entered Pueblo de Los Angeles, California with flags flying and band playing. USMC Captain Archibald H. Gillespie, (Frémont's second in command of the California Battalion), with an inadequate force of 40 to 50 men, were left to occupy and keep order in the largest town (about 3,500) in Alta California—Los Angeles. The Californio government officials had already fled Alta California. In September 1846 a minor Californio led and organized revolt under José María Flores, José Antonio Carrillo and Andrés Pico, broke out in Los Angeles and the out numbered United States force there of 40–50 men evacuated the city for a time. Later, U.S. forces fought minor skirmishes with the Californio Lancers in the Battle of San Pasqual, the Battle of Dominguez Rancho, and the Battle of Rio San Gabriel. After the Los Angeles revolt started, the California Battalion was expanded to a force of about 400 men. In early January 1847, a 600-man joint force of U.S. Marine, U.S. Navy bluejacket sailors, General Stephen W. Kearny's 80 U.S. Army dragoons (cavalrymen), who had arrived over the Gila river trail in December 1846, and about two companies of Fremont's California Battalion re-occupied Los Angeles after some very minor skirmishes (mostly posturing)—after four months the same U.S. flag again flew over Los Angeles. The minor armed resistance in California ceased when the Californios signed the Treaty of Cahuenga on January 13, 1847. About 150 Californios who were worried about possible punishment from the Americans for not keeping their non-aggression promises rounded up about 300 horses and retreated into Sonora, Mexico over the Yuma Crossing Gila River trail. The Californios, who had wrested control of California from Mexico in 1845, now had a new and much more stable government.
After the Treaty of Cahuenga was signed in early 1847, the Pacific Squadron then went on to capture all Baja California cities and harbors and sink or capture all the Mexican Pacific Navy they could find. Baja California was returned to Mexico in subsequent Treaty of Guadalupe Hidalgo negotiations. California was under U.S. control by January 1847 and formally annexed and paid for by the U.S. in the Treaty of Guadalupe Hidalgo signed in 1848.
After hostilities had ceased with the signing of the Treaty of Cahuenga on January 13, 1847, on January 22, 1847 Commodore Stockton's replacement, Commodore William B. Shubrick, showed up in Monterey in the razee USS Independence with 54 guns and about 500 crew members. On January 27, 1847 the transport Lexington showed up in Monterey, California with a regular U.S. Army artillery company of 113 men under Captain Christopher Tompkins.
More reinforcements of about 320 soldiers (and a few women) of the Mormon Battalion arrived at San Diego on January 28, 1847—after hostilities had ceased. They had been recruited from the Mormon camps on the Missouri River—about 2,000 miles (3,200 km) away. These troops were recruited with the understanding they would be discharged in California with their weapons. Most were discharged before July 1847. More reinforcements in the form of Colonel Jonathan D. Stevenson's 1st Regiment of New York Volunteers of about 648 men showed up in March–April 1847—again after hostilities had ceased. After desertions and deaths in transit, four ships brought Stevenson's 648 men to California. Initially they took over all of the Pacific Squadron's on-shore military and garrison duties and the Mormon Battalion and California Battalion's garrison duties.
The New York Volunteer companies were deployed from San Francisco in Alta California to La Paz, Mexico in Baja California. The ship Isabella sailed from Philadelphia on 16 August 1847, with a detachment of one hundred soldiers, and arrived in California on 18 February 1848, the following year, at about the same time that the ship Sweden arrived with another detachment of soldiers. These soldiers were added to the existing companies of Stevenson's 1st Regiment of New York Volunteers. Stevenson's troops were recruited with the understanding that they would be discharged in California. When gold was discovered in late January 1848, many of Stevenson's troops deserted.
The U.S. 1850 California Census asks state of birth of all residents and finds about 7300 residents that were born in California. The San Francisco, Contra Costa and Santa Clara county U.S. censuses were lost or burned in one of San Francisco's many fires. Adding the approximate 200 Hispanics in San Francisco (1846 directory) and an unknown (but small as shown in 1852 CA Census recount) number of Hispanics in Contra Costa and Santa Clara county in 1846 gives less than 8,000 Hispanics state wide in 1846 before hostilities commenced. The number of California Indians is unknown since they were not included in the 1850 census but has been roughly estimated to be between 50,000 and 150,000.
After 1847, California was controlled (with much difficulty due to desertions) by a U.S. Army-appointed military governor and an inadequate force of a little over 600 troops. Due to the California Gold Rush, by 1850 California had grown to have a non-Indian and non-Californio population of over 100,000 Despite a major conflict in the U.S. Congress on the number of slave versus non-slave states, the large, rapid and continuing California population gains and the large amount of gold being exported east gave California enough clout to choose its own boundaries, select its representatives, write its Constitution, and be admitted to the Union as a free state in 1850 without going through territorial status as required for most other states.
The Treaty of Guadalupe Hidalgo formally ended the Mexican–American War in February 1848. For $15,000,000, and the assumption of U.S. debt claims against Mexico, the new state of Texas's boundary claims were settled, and New Mexico, California, and the unsettled territory of several future states of the American Southwest were added to U.S. control.
From 1847 to 1850, California had military governors appointed by the senior military commander in California. This arrangement was distinctly unsettling to the military, as they had no inclination, precedent, or training for setting up and running a government. President James K. Polk in office from March 4, 1845 – March 4, 1849, tried to get the 1848 Congress to make California a territory with a territorial government and again in 1849 but was unsuccessful in getting Congress to agree on the specifics of how this was to be done—the issues was the number of free states vs. slave state problem.
General Bennett C. Riley who had fought in the Siege of Veracruz and Chapultepec during the Mexican–American War and considered an able military commander, was the last military governor of California in 1849-1850. In response to popular demand for a better more representative government, General Riley issued an official proclamation dated June 3, 1849, calling for a Constitutional Convention and an election of representatives on August 1, 1849.
Convention delegates were chosen by secret ballot but lacking any census data as to California's population and where they lived its representatives only roughly approximated the rapidly changing state population as later shown in the 1850 U.S. California Census taken a year later. The 48 delegates chosen were mostly pre-1846 American settlers; eight were native born Californios who had to use interpreters. The new miners in El Dorado County were grossly under-represented as they had no representatives at the convention despite then being the most populated county in California. After the election the California Constitution Convention met in the small town and former Californio capital of Monterey, California, on September 1849 to write a state constitution.
Like all U.S. State's constitutions, the California Constitution adhered closely to the format and government roles set up in the original 1789 U.S. Constitution—differing mainly in details. The Constitutional Convention met for 43 days debating and writing the first California Constitution. The 1849 Constitution copied (with revisions) a lot out of the Ohio and New York Constitutions but had parts that were originally several different state constitutions as well as original material.
The 21-article Declaration of Rights in the California Constitution (Article I: Sec.1 to Sec.-21) was broader than the U.S. Constitution's 10-article Bill of Rights. There were four other significant differences from the U.S. Constitution. The convention chose the boundaries for the state—unlike most other territories, whose boundaries were set by Congress (Article XII). Article IX encouraged statewide education and provided for a system of common schools partially funded by the state and provided for the establishment of a University (University of California). The California version outlawed slavery, except as punishment (Article I Sec. 18) and dueling (Article XI Sec.2) and gave women and wives the right to own and control their own property (Article XI Sec. 14).
The debt limit for the state was set at $300,000 (Article VIII). Like all other states they guaranteed the rights of citizens to sue in Civil court to uphold the rights of contracts and property (Article I Sec. 16). They created a court system with a supreme court with judges who had to be confirmed every 12 years.(Article VI) They set up the states original 29 counties (Article I Sec. 4), created a legislature of two houses, set up polling places to vote, set up uniform taxation rules. The 1849 Constitution guaranteed the right to vote to "Every citizen of California, declared a legal voter by this Constitution, and every citizen of the United States, a resident of this State on the day of election, shall be entitled to vote at the first general election under this Constitution, and on the question of the adoption thereof (Article XII Sec. 5)".
The California Constitution was ratified by popular vote at an election held on a rainy November 13, 1849 (as specified in Article 12 Sec. 8). The Pueblo de San Jose was chosen as the first state capitol (Article XI Sec. 1). Soon after the election they set up a provisional state government that set up the counties, elected a governor, senators, and representatives, and operated for ten months setting up a state government before California was given official statehood by Congress on September 9, 1850, as part of the Compromise of 1850.
Thirty eight days later the Pacific Mail Steamship SS Oregon brought word to San Francisco on October 18, 1850, that California was now the 31st state. There was a celebration that lasted for weeks. The state capital was variously at San Jose (1850–1851), Vallejo (1852–1853), and Benicia (1853–1854) until Sacramento was finally selected in 1854. The constitution of 1849 was only judged a partial success as a founding document and was superseded by the current constitution, which was first ratified on May 7, 1879.
The first to hear confirmed information of the California Gold Rush were the people in Oregon, the Sandwich Islands (Hawaii), Mexico, Peru, and Chile. They were the first to start flocking to the state in late 1848. By the end of 1848, some 6,000 Argonauts had come to California. Americans and foreigners of many different countries, statuses, classes, and races rushed to California for gold. Almost all (~96%) were young men. Women in the California Gold Rush were few and had many opportunities to do new things and take on new tasks. Argonauts, as they were often called, walked over the California Trail or came by sea. About 80,000 Argonauts arrived in 1849 alone—about 40,000 over the California trail and 40,000 by sea.
San Francisco was designated the official port of entry for all California ports where U.S. customs (also called tariffs and Ad valorem taxes) (averaging about 25%) were collected by the Collector of Customs from all ships bearing foreign goods. The first Collector of customs was Edward H. Harrison, appointed by General Kearny. Shipping boomed from the average of about 25 vessels from 1825 to 1847 to about 793 ships in 1849 and 803 ships in 1850. All ships were inspected for what goods they carried. Passengers disembarking in San Francisco had one of the easier accesses to the gold country since they could take another ship from there to get to Sacramento and several other towns.
San Francisco shipping boomed, and wharves and piers had to be developed to handle the onslaught of cargo--Long Wharf was probably the most prominent. To meet the demands of the Gold Rush, ships bearing food, liquors of many types, tools, hardware, clothing, complete houses, lumber, building materials, etc. as well as farmers, business men, prospective miners, gamblers, entertainers and prostitutes, etc. from around the world came to San Francisco. Initially, the large supplies of food needed were imported from close ports in Hawaii, Mexico, Chile, Peru, and the future state of Oregon. The Californios initially prospered, as there was a sudden increase in the demand for livestock. These food shipments changed mainly to shipments from Oregon and internal shipments in California as agriculture was developed in both states.
Starting in 1849, many of the ship crews jumped ship and headed for the gold fields when they reached port. Soon San Francisco Bay had many hundreds of abandoned ships anchored offshore. The better ships were recrewed and put back in the shipping and passenger business. Others were bought cheap and hauled up on the mud flats and used as store ships, saloons, temporary stores, floating warehouses, homes, and a number of other uses. Many of these repurposed ships were partially destroyed in one of San Francisco's many fires and ended up as landfill to expand the available land. The population of San Francisco exploded from about 200 in 1846 to 36,000 in the 1852 California Census.
In San Francisco, many people were initially housed in wooden houses, ships hauled up on the mud flats to serve as homes or businesses, wood-framed canvas tents used for saloons, hotels and boarding houses as well as other flammable structures. All these canvas and wood structures, combined with a lot of drunken gamblers and miners, led almost inevitably to many fires. Most of San Francisco burned down six times in six Great Fires between 1849 and 1852.
Californios who lived in California had finally had enough of the Mexican government and seized control of the territory of Alta California in 1846. At the time gold was discovered in 1848, California had about 9,000 former Californios and about 3,000 United States citizens including members of Colonel Jonathan D. Stevenson's 1st Regiment of New York Volunteers and discharged members of the California Battalion and Mormon Battalions. The Pacific Squadron secured San Francisco Bay.
The state was formerly under the military governor Colonel Richard Barnes Mason who only had about 600 troops to govern California—many of these troops deserted to go to the gold fields. Before the Gold Rush, almost no infrastructure existed in California except a few small Pueblos (towns), secularized and abandoned Missions and about 500 large (averaging over 18,000 acres (73 km2)) ranchos owned the Californios who had mostly taken over the Missions land and livestock. The largest town in California prior to the Gold Rush was the Pueblo de Los Angeles with about 3,500 residents.
The sudden massive influx into a remote area overwhelmed the state infrastructure, which in most places didn't even exist. Miners lived in tents, wood shanties, wagons, or deck cabins removed from abandoned ships. Wherever gold was discovered, hundreds of miners would collaborate to put up a camp and stake their claims. With names like Rough and Ready and Hangtown (Placerville, California), each camp often had its own saloon, dance hall, and gambling house.
Some of the first Argonauts, as they were also known, traveled by the all sea route around Cape Horn. Ships could take this route year round and the first ships started leaving East Coast ports as early as November 1848. From the East Coast, a sailing voyage around the southern tip of South America would typically take five to eight months—averaging about 200 days by standard sailing ship. This trip could easily cover over 18,000 nautical miles (33,000 km) depending on the route chosen—some even went by way of the Sandwich Islands (Hawaii). When clipper ships began to be used starting in early 1849, they could complete this journey in an average of only 120 days; but they typically carried few passengers. They specialized in high value freight.
Starting in 1848 before gold in California was even confirmed, Congress had contracted with the Pacific Mail Steamship Company to set up regular paddle steamer packet ship, mail, passenger and cargo routes in the Pacific Ocean. This was to be a regular route from Panama, Nicaragua and Mexico to and from San Francisco and Oregon. The Atlantic Ocean mail contract from East Coast cities and New Orleans, Louisiana to and from the Chagres River in Panama was won by the United States Mail Steamship Company whose first steamship, the SS Falcon (1848') was dispatched on December 1, 1848. The SS California (1848), the first Pacific Mail Steamship Company steamship, showed up in San Francisco loaded with gold seekers on February 28, 1849 on its first trip from Panama and Mexico after steaming around Cape Horn from New York. Once the California Gold Rush was confirmed, other paddle steamers soon followed on both the Pacific and Atlantic routes. By late 1849 paddle steamers like the SS McKim (1848) were carrying miners and business men over the 125 miles (201 km) trip from San Francisco up the Sacramento River to Sacramento and Marysville, California. Steam powered tugboats started working in the San Francisco Bay soon after this.
Agriculture expanded throughout the state to meet the food needs of the new settlers. Agriculture was soon found to be limited by the difficulty of finding enough water in the right places to grow irrigated crops. Winter wheat planted in the fall and harvested in the spring was one early crop that grew well without irrigation. At the beginning of the Gold Rush, there was no written law regarding property rights in the goldfields, and a system of "staking claims" was developed by the miners. The Gold Rush also had negative effects: Native Americans were pushed off of traditional lands, and gold mining caused environmental harm.
In the early years of the California Gold Rush, placer mining methods were used, from panning to "cradles" and "rockers" or "long-toms", to diverting the water from an entire river into a sluice alongside the river, and then digging for gold in the gravel down to the rocky river bottom. This placer gold had been freed by the slow disintegration, over geological time, that freed the gold from its ore. This free gold was typically found in the cracks in the rocks found at the bottom of the gravel found in rivers or creeks, as the gold typically worked down through the gravel or collected in stream bends or bottom cracks. Some 12-million ounces (370 t) of gold were removed in the first five years of the Gold Rush. This gold greatly increased the available money in the United States, which was on the gold standard at that time—the more gold you had, the more you could buy.
As the easier gold was recovered, the mining became much more capital and labor-intensive as the hard rock quartz mining, hydraulic mining, and dredging mining evolved. By the mid-1880s, it is estimated that 11-million ounces (340 t) of gold (worth approximately US$6.6 billion at November 2006 prices) had been recovered via "hydraulicking," a style of hydraulic mining that later spread around the world, despite its drastic environmental consequences. By the late 1890s, dredging technology had become economical, and it is estimated that more than 20 million ounces (620 t) were recovered by dredging (worth approximately US$12 billion at November 2006 prices). Both during the Gold Rush and in the decades that followed, hard-rock mining wound up being the single-largest source of gold produced in the Gold Country.
By 1850, the U.S. Navy started making plans for a west coast navy base at Mare Island Naval Shipyard. The greatly increased population, along with the new wealth of gold, caused: roads, bridges, farms, mines, steamship lines, businesses, saloons, gambling houses, boarding houses, churches, schools, towns, mercury mines, and other components of a rich modern (1850) U.S. culture to be built. The sudden growth in population caused many more towns to be built throughout Northern, and later Southern, California and the few existing towns to be greatly expanded. The first cities started showing up as San Francisco and Sacramento exploded in population.
Most California Indians are thought to have been located near the coast, the same areas the Spanish Missions were established. Since California Indians had no agriculture before it was introduced by the Franciscan padres, they were strictly hunter-gather society tribes which could not support large populations—large populations require agriculture. During the Spanish and Mexican California occupation period the tribes were nearly all coastal tribes were induced to join a mission. So many Mission Indians died from exposure to harsh conditions at the missions and diseases like measles, diphtheria, smallpox, syphilis, etc. that at times raids were undertaken to new villages in the interior to supplement the supply of Indian women at the missions. As reported by Krell, as of December 31, 1832, the mission Franciscan padres from 1800 to 1830 had performed a combined total of 87,787 baptisms and 24,529 marriages, and recorded 63,789 deaths. If Krell's numbers are to be believed (others have slightly different numbers) the Mission Indian population had declined from a peak of about 87,000 in about 1800 to about 14,000 in 1832 and continued to decline. The Missions were becoming ever more strained as the number of Indian converts drastically declined and the deaths greatly exceeded the births. The ratio of Indian births to deaths is believed to have been less than 0.5 Indian births per death. After the missions were disbanded in 1832 the surviving Indians mostly went to work on the about 500 newly established ranchos who appropriated the mission's "property" (about 1,000,000 acres (400,000 ha) acres/mission). The Indians typically worked at one of the four Spanish pueblos as servants or at the newly established ranchos for room and board or attempted to join other tribes in the interior. The new ranchos occupied nearly all their original tribal territories.
The new wave of immigration that was sparked by the gold rush would continue to have a disastrous impact on California's native population, which continued to precipitously decline mainly due to Eurasian diseases to which they had no natural immunity. Like when the Spanish missions in California were established the native inhabitants were often forcefully removed from their traditional tribal lands by incoming miners, ranchers, and farmers. There were a number of massacres, including the Yontoket Massacre, the Bloody Island Massacre at Clear Lake, and the Old Shasta Massacre, in which perhaps hundreds of indigenous people were killed. Thousands more are thought to have died due to disease. Combined with a low birth rate for Indian women the Indian population precipitously declined.
Between 1850 and 1860, the state of California paid around 1.5 million dollars (some $250,000 of which was reimbursed by the federal government) to hire "militias" whose purpose was to protect settlers from the indigenous populations. These "private military forays" were involved in several of the above-mentioned massacres, and sometimes participated in the "wanton killing" of Native peoples. The first governor of California, Peter Burnett, openly called for the extermination of the Indian tribes, and in reference to the violence against California's Native population, he said, “That a war of extermination will continue to be waged between the two races until the Indian race becomes extinct, must be expected. While we cannot anticipate the result with but painful regret, the inevitable destiny of the race is beyond the power and wisdom of man to avert.” As a result, the rise of modern California equalled great tragedy and hardship for the native inhabitants. Several scholars, including Benjamin Madley and Ed Castillo, have described the actions of the California government as a genocide.
In subsequent decades after 1850, the native population of more than 100 tribes were gradually placed in a series of reservations and rancherias, which were often very small and isolated and lacked adequate natural resources or funding from the government to sustain the populations living on them in the hunter-gathering style they were used to living.
The Maritime history of California includes Native American dugouts, tule canoes, and sewn canoes (Tomols); early European explorers; Colonial Spanish and Mexican California maritime history; Russians and Aleut kayaks in the Maritime Fur Trade. U.S. Naval Activity including: Pacific Squadron, Mexican–American War. California Gold Rush shipping includes paddle steamers, Clippers, sailing ships, passage via Panama, Nicaragua, Mexico, and Cape Horn and the growth of the Port of San Francisco. Also included are sections on California naval installations, California shipbuilding, California shipwrecks, and California lighthouses.
Tribes in northwest California practiced slavery long before the arrival of Europeans. There were never black slaves owned by Europeans, and many free men of African ancestry joined the California Gold Rush (1848–1855). Some returned east with enough gold to purchase their relatives. The California Constitution of 1849 outlawed any form of slavery in the state, and later the Compromise of 1850 allowed California to be admitted into the Union, undivided, as a free state. Nevertheless, as per the 1853 Act for the Government and Protection of Indians, a number of Native Americans were formally enslaved in the state, a practice that continued until the mid-1860s, when California changed its laws to conform to the 14th Amendement.
The possibility of splitting off Southern California as a territory or a state was rejected by the national government, and the idea was dead by 1861 when patriotic fervor swept California after the attack on Fort Sumter.
California's involvement in the American Civil War included sending gold east, recruiting or funding a limited number of combat units, maintaining numerous fortifications and sending troops east, some of whom became famous. Following the split in the Democratic Party in 1860, Republican supporters of Lincoln took control of the state in 1861, minimizing the influence of the large southern population. Their great success was in obtaining a Pacific railroad land grant and authorization to build the Central Pacific as the western half of the transcontinental railroad.
California was settled primarily by Midwestern and Southern farmers, miners, and businessmen. Though the southerners and some Californios tended to favor the Confederacy, the state did not have slavery, and they were generally powerless during the war itself. They were prevented from organizing and their newspapers were closed down by denying them the use of the mail. Former Sen. William M. Gwin, a Confederate sympathizer, was arrested and fled to Europe.
Nearly all of the men who volunteered as Union soldiers stayed in the West, within the Department of the Pacific, to guard forts and other facilities, occupy secessionist regions, and fight Indians in the state and the western territories. Some 2,350 men in the California Column marched east across Arizona in 1862 to expel the Confederates from Arizona and New Mexico. The California Column then spent most of the remainder of the war fighting hostile Indians in the area.
Even before Mexico gained control of Alta California in 1821, the onerous Spanish rules in effect from 1770 to 1821 against trading with foreigners began to break down as the declining Spanish fleet couldn't enforce their no trading policies. The Californios, with essentially no industries or manufacturing capabilities, were eager to trade for new commodities, glass, hinges, nails, finished goods, luxury goods and other merchandise. The Mexican government abolished the no trade with foreign ships policy and soon regular trading trips were being made. The main products of these California Ranchos were cow hides (called California greenbacks), tallow (rendered fat for making candles and soap) and California/Texas longhorn cattle horns that were traded for other finished goods and merchandise. This hide-and-tallow trade was mainly carried on by Boston-based ships that traveled for about 200 days in sailing ships about 17,000 miles (27,000 km) to 18,000 miles (29,000 km) around Cape Horn to bring finished goods and merchandise to trade with the Californio Ranchos for their hides, tallow and horns. The cattle and horses that provided the hides, tallow and horns essentially grew wild. The Californios' hides, tallow and horns provided the necessary trade articles for a mutually beneficial trade. The first United States, English and Russian trading ships began showing up in California before 1816. The classic book Two Years Before the Mast by Richard Henry Dana, Jr. written about 1832 provides a good first hand account of this trade.,
From 1825 to 1848 the average number of ships traveling to California increased to about 25 ships per year—a large increase from the average of 2.5 ships per year from 1769 to 1824. The port of entry for trading purposes was the Alta California Capital, Monterey, California, where custom duties (tariffs) of about 100% were applied. These high duties gave rise to much bribery and smuggling, as avoiding the tariffs made more money for the ship owners and made the goods less costly to the customers. Essentially all the cost of the California government (what little there was) was paid for by these tariffs (custom duties). In this they were much like the United States in 1850, where about 89% of the revenue of its federal government came from import tariffs (also called Customs or ad valorem taxes), although at an average rate of about 20%.
Ships after 1848 provided easy, cheap, links among the coastal towns within California and on routes leading there. Nearly all cargo to California came by sailing ship over the more than 17,000 miles (27,000 km) route from the east coast or Europe around Cape Horn in South America. This route took about 200 days by "standard" sailing ship or about 120 days by Clipper. The Panama and Nicaragua routes provided a shortcut for getting from the East Coast to California and a brisk maritime trade developed, featuring fast paddle steamers from cities on the east coast, New Orleans, Louisiana and Havana Cuba to the Caribbean mouth of the Chagres River in Panama and the mouth of San Juan River in Nicaragua. After a trip up the Chagres River by native dugouts the last 20 miles (32 km) were completed to Panama City by mule back. The trip up the San Juan River in Nicaragua was usually done by small steam launch to Lake Nicaragua, a boat trip on the lake and a final 25 miles (40 km) trip by stage coach or mule back to San Juan del Sur or other city in the Pacific side of Nicaragua. After 1855 when the Panama Railroad was completed the Nicaragua route largely shut down.
In 1846 the Oregon boundary dispute was settled with Great Britain and California was under U.S. control in 1847 and annexed and paid for in 1848. The United States was now a Pacific Ocean power. Starting in 1848 the U.S. Congress, after the annexation of California but before the California Gold Rush was confirmed there, had subsidized the Pacific Mail Steamship Company with $199,999 to set up regular packet ship, mail, passenger and cargo routes in the Pacific Ocean. This was to be a regular scheduled route from Panama City, Nicaragua and Mexico to and from San Francisco and Oregon. Panama City was the Pacific terminus of the Isthmus of Panama trail across Panama. The Atlantic Ocean mail contract from East Coast cities and New Orleans to and from the mouth of the Chagres River in Isthmus of Panama was won by the United States Mail Steamship Company whose first paddle wheel steamship, the SS Falcon (1848) was dispatched on 1 December 1848 to the Caribbean (Atlantic) terminus of the Isthmus of Panama trail—the Chagres River.
In 1849 William H. Aspinwall, the man who had won the bid for the building and operating of the Pacific mail steamships, conceived a plan to construct a railway across the isthmus of Panama; he and his partners created a company registered in New York, the Panama Railroad Company, raised US$1,000,000 from the sale of stock, and hired companies to conduct engineering and route studies. Their venture happened to be well-timed, as the discovery of gold in California in January 1848 created a rush of emigrants wanting to cross the Isthmus of Panama and go on to California. Cholera, yellow fever, and malaria took a deadly toll on the Railroad workers, and despite the continual importation of large numbers of new workers, there were times when the work stalled for simple lack of alive and semi-fit workers. All supplies and nearly all foodstuffs had to be imported from thousands of miles away, greatly adding to the cost of construction. Laborers came from the United States, the Caribbean Islands, and as far away as Ireland, India, China, and Australia. Upon completion in 1855 the road stretched 47 miles (76 km) and had cost over $8,000,000 and about 5,000 lives. By 1855 this arduous trip across the Isthmus of Panama had been shortened to a one day $25.00 excursion on the Panama Railroad.
The first of three Pacific Mail Steamship Company paddle wheel steamships, the SS California (1848), contracted for on the Pacific route, left New York City on 6 October 1848. This was before the gold strikes in California were confirmed and she left with only a partial passenger load in her 60 saloon (about $300 fare) and 150 steerage (about $150 fare) passenger compartments. Only a few were going all the way to California. As word of the gold strikes spread, the SS California picked up more passengers in Valparaiso Chile and Panama City Panama and showed up in San Francisco on 28 February 1849. She was loaded with about 400 gold seeking passengers; twice the number of passengers it had been designed for. In San Francisco all her passengers and crew except the captain and one man deserted the ship and it would take the Captain two more months to gather a much better paid return crew to return to Panama city an establish the route they had been contracted for. Many more paddle steamers were soon running from the east coast cities to the Chagres River in Panama and the San Juan River in Nicaragua. By the mid 1850s there were over ten Pacific and ten Atlantic/Caribbean paddle wheel steamboats shuttling high valued freight like passengers, gold and mail between California and both the Pacific and Caribbean ports. The trip to the east coast could be executed after about 1850 in as short as 40 days if all ship connections could be met with a minimum of waiting.
Steamboats plied the Bay Area and the Sacramento and San Joaquin Rivers that flowed nearer the goldfields, moving passengers and supplies from San Francisco to Sacramento, Marysville and Stockton, California—the three main cities supplying the gold fields. The city of Stockton, on the lower San Joaquin, quickly grew from a sleepy backwater to a thriving trading center, the stopping-off point for miners headed to the gold fields in the foothills of the Sierra. Rough ways such as the Millerton Road which later became the Stockton - Los Angeles Road quickly extended the length of the valley and were served by mule teams and covered wagons. Riverboat navigation quickly became an important transportation link on the San Joaquin River, and during the "June Rise", as boat operators called the San Joaquin's annual high water levels during snow melt, on a wet year large craft could make it as far upstream as Fresno. During the peak years of the gold rush, the river in the Stockton area was reportedly crowded with hundreds of abandoned oceangoing craft, whose crew had deserted for the gold fields. The multitude of idle ships was such a blockade that at several occasions they were burned just to clear a way for riverboat traffic. Initially, with few roads, pack trains and wagons brought supplies to the miners. Soon a system of wagon roads, bridges, ferries and toll roads were set up many of them maintained by tolls collected from the users. Large freight wagons pulled by up to 10 mules replaced pack trains, and toll roads built and kept passable by the tolls made it easier to get to the mining camps, enabling express companies to deliver firewood, lumber, food, equipment, clothes, mail, packages, etc. to the miners. Later when communities developed in Nevada some steamboats were even used to haul cargo up the Colorado River as high as where Lake Mead in Nevada is today.
The Butterfield Overland Mail Stage Line  was a stagecoach service operating from 1857 to 1861 of over 2,800 miles (4,500 km). It carried passengers and U.S. Mail from Memphis, Tennessee and St. Louis, Missouri to San Francisco, California. The Butterfield Overland Stage Company had more than 800 people in its employ, had 139 relay stations, 1800 head of stock and 250 Concord Stagecoaches in service at one time.
The routes from each eastern terminus met at Fort Smith, Arkansas, and then continued through Indian Territory (Oklahoma), Texas, and the future states of New Mexico, Arizona along the Gila River trail, across the Colorado River at the Yuma Crossing, and into California ending in San Francisco.
With the prospects of the civil war looming the Butterfield stage contract was terminated and the stage route to California rerouted. An Act of Congress, approved March 2, 1861, discontinued this route and service ceased June 30, 1861. On the same date the central route from St. Joseph, Missouri, to Salt Lake City, Utah, Carson City, Nevada and on to Placerville, California, went into effect. From the end of Central Overland route in Carson City, Nevada they followed the Placerville Toll road route over Johnson Pass (now U.S. Highway 50) to California since it was the fastest and only route that was then kept open in winter across the Sierra Nevada (U.S.) mountains. The 1800 draft horses and mules, 250 coaches, etc., on the southern Gila River route Butterfield Stage route were pulled off and moved to the new route between St. Joseph, Missouri and Placerville, California along the existing Oregon, California Trails to Salt Lake City and then through central Utah and Nevada. It took about three months to make the transfer of stages and stock, and to build a number of new stations, secure hay and grain, and get everything in readiness for operating a six-times-a-week mail line. On 30 June 1861 the Central Overland California Route from St. Joseph, Missouri, to Placerville, California, went into effect. By traveling day and night and using team changes about every 10 miles (16 km) the stages could make the trip in about 28 days. News paper correspondents reported that they had a preview of "hell" when they took the trip. The new line was designated by the post-office department as the "Central Overland California Route."
Once cargo was moved off the ocean and rivers it nearly always transported by horse or ox drawn wagons—still true till about 1920. When there was not a wagon trail the cargo was shifted to mule pack trains or carried on the backs of the miners. Lumber to build new homes, sluice boxes, etc. was a crying need and food to feed the miners was needed even more. Fortunately California has a lot of native timber and even as early as 1850 there were saw mills set up to turn some of this timber into lumber. Food was initially imported from any and all west coast ports from Hawaii, Oregon or Mexico where it could be obtained. The lumber and food were transported by ships that had initially carried gold rush passengers and in many cases abandoned in the bay and could usually be bought cheap. The many goods the gold miners needed for a "modest" 1850s lifestyle were nearly always hauled by horse, mule or ox drawn wagons. Wheat and timber were early products from Oregon and the Columbia River area that could be economically imported. Soon it was found that some types of spring wheat could be planted in the fall in California and the mild winter with its rains would allow good crops to be harvested in the spring without irrigation. Later. much of this wheat was exported to ports around the world, California finally had a return cargo for its many incoming ships. California in the 1890s became the foremost wheat producer in the U.S. but could not really compete on the east coast with the burgeoning wheat lands being brought into production in the midwest were much closer to their markets. Other crops in California were usually found to be much more profitable and California joined the rest of the nation in importing most of its wheat from farms in the midwest.
The year 1848 saw the close of Mexican control over Alta California, this period also marked the beginning of the rancheros’ greatest prosperity. The Californio rancho society before 1848 had few resources except large herds of Longhorn cattle which grew almost wild in California. The Ranchos produced the largest cowhide (called California Greenbacks) and tallow business in North America by killing and skinning their cattle and cutting off their fat. The cowhides were staked out to dry and the tallow was put in large cowhide bags. The rest of the animal was left to rot or feed the California grizzly bears then common in California. The traders who traded for the hides, tallow and sometimes horns hauled them back to the east cost where the hides were used to make a large vaiety of leather products, most of the tallow was used for making candles and the horns were mostly used for making buttons. A trading trip typically took over two years. The classic book Two Years Before the Mast (originally published 1840) by Richard Henry Dana, Jr. gives a good first-hand account of a two-year sailing ship sea trading voyage to California which he took in 1834-5. Dana mentions that they also took back a large shipment of California longhorn horns. Horns were used to make a large number of items in this time period. (The eBook of Two Years Before the Mast is available at Gutenberg project. A large part of the Californio diet was beef, but since there was no easy way to preserve it most of the time another animal was killed when fresh meat was needed as when visitors showed up—the hides and tallow could be salvaged and very little was lost. The market for beef dramatically changed with the onset of the Gold Rush, as thousands of miners, businessmen and other fortune seekers flooded into northern California. These newcomers needed meat, and cattle prices soared from the $1.00 to $2.00 per hide to $30.00-$50.00 per cow. From about 1848 to about 1860 the rancheros enjoyed the "golden" days of Hispanic California. The largely illiterate ranchero owners lost nearly all their land to a few bad years for cattle in the 1860s and the many mortgages they had taken out to finance a "prosperous" life style and could no longer pay back. In the early years of the Gold Rush the demand for beef was so great that there are records of about 60,000 longhorns being herded from Texas to California.
The Pony Express used much of this same route across Nevada and the Sierras in 1860-1861. These combined stage and Pony Express stations along the Central Route across Utah and Nevada were joined by the first transcontinental telegraph stations (completed 24 October 1861). The Pony express terminated soon after the telegraph was established. This combination wagon-stagecoach-pony express-telegraph line route is labeled the Pony Express National Historic Trail on the National Trail Map. From Salt Lake City, the telegraph line followed much of the Mormon-California-Oregon trail(s) to Omaha, Nebraska. After the first transcontinental railroad was completed in 1869, the telegraph lines along the railroad tracks became the main line, since the required relay stations, lines and telegraph operators were much easier to supply and maintain along the railroad. The telegraph lines that diverged from the railroad lines or significant population centers were largely abandoned.
After the 1870s, stagecoaches provided the primary form of local passenger and mail transportation between inland towns that were not connected to a railroad, with sailing ships and paddle wheel steamships connecting port cities. Freight wagons still hauled nearly all cargo. Even when railroads arrived, stages were essential to link more remote areas to the railheads. Top of the line in quality, with crowded discomfort, was the nine-passenger Concord stagecoach, but the cheaper, rougher "mud wagons" were also in general use. The Wells Fargo company contracted with independent lines to deliver its express packages and transport gold bullion and coins. Stagecoach travel was usually uncomfortable as passengers were often crowded together in limited space, dust pouring through open windows from rough unpaved roads, rough rides, un-bathed fellow passengers and poorly sprung steel tired stagecoaches. Some drivers were famous for their skill in driving six horses down winding roads at top speed, fortunately only rarely overturning. Rate competition from competing stage lines reduced fares to as little a two cents per mile on some routes—a $1.00/day was then a common wage. Bandits found robbing coaches a profitable if risky venture as they may be shot or hanged if caught. U.S. government mail subsidies provided essential base income for many stage lines, but running a stage line was often a financially unstable business enterprise.
California's first railroad was built from Sacramento to Folsom, California starting in February 1855. This 22 miles (35 km) line was finished in February 1856. This railroad was meant to take advantage of the prosperous gold diggings and their need for supplies in Placerville, California but were completed at about the same time the lucrative placer mining near there came to an end. Starting in about 1860 this short railroad was used to haul part of the cargo part ways to the Comstock Lode mines in Nevada (See: California Trail) The first Transcontinental Railroad from Sacramento, California to Omaha, Nebraska was completed on 9 May 1869. The Central Pacific Railroad, the Pacific end of the railroad, largely took over nearly all freight across the Sierra Nevada (U.S.) mountains in Northern California. By 1870 there were railroad connections to Oakland, California and via a train ferry to San Francisco, California from Sacramento—effectively connecting all the major cities in California then to the east coast.
Southern California's first railroad, the Los Angeles & San Pedro Railroad, was inaugurated in October, 1869 by John G. Downey and Phineas Banning. It ran 21 miles (34 km) between San Pedro and Los Angeles. In 1876 California's first railroad linking Los Angeles with Northern California was completed when the San Joaquin line of the Southern Pacific Railroad finished the San Fernando Railroad Tunnel through the Tehachapi mountains, linking Los Angeles to the Central Pacific Railroad. This route to Los Angeles followed the Tehachapi Loop, a 0.73-mile (1.17 km) long 'spiral track', or helix, through Tehachapi Pass in Kern County and connected Bakersfield and the San Joaquin Valley to Mojave in the Mojave Desert.
Although most of California's railroads started off as short line railroads the period from 1860 to 1903 saw a series of railroad mergers and acquisitions that led to the creation of four major inter-state railroads servicing the state (the Southern Pacific Railroad, Union Pacific Railroad, Santa Fe Railroad and Western Pacific Railroad). Each of these railroads controlled one (and Southern Pacific controlled two) of the transcontinental railroads which linked California with states farther East. The railroads moved freight and passengers in large quantities and allowed the state's economy and population to expand rapidly during the late 19th and early 20th centuries.
By the 1890s the construction of electric railroads had begun in California and the by the early 20th century several systems existed to serve California's largest cities. The state's electric railroad systems included the San Diego Electric Railway, Los Angeles' Pacific Electric system, the Los Angeles Pacific Railroad, East Bay Electric Lines and the San Francisco, Oakland, and San Jose Railway and Interurban rail systems such as the Sacramento Northern Railway were also constructed. By the 1920s, Los Angeles' Pacific Electric system was the largest electric railroad in the world.
The expansion of American railroads peaked in the 1910s and during the Great Depression many railroads suffered financial difficulties which led to some railroad bankruptcies. World War II caused a surge in the use of California's railroads but with the government funded construction of the inter-state highway system in the 1950s and the expansion of the U.S. airline industry passenger rail service declined dramatically.
The 1970s saw the end of private passenger railroads in California and the creation of a national passenger railroad, Amtrak and the Bay Area opened the BART rail-system. In the 1980s and 1990s commuter railroads where established in the Bay Area (Caltrain and Altamont Corridor Express), Los Angeles (Metrolink) and San Diego (Coaster) and light rail networks were build or expanded in most urban areas.
