Loudoun County (/ˈldən/ LOWD-ən) is a county located in the Commonwealth of Virginia. As of 1 July 2013, the population was estimated to be 347,969,[2] making the county the third-most populous in Virginia. Loudoun County's county seat is Leesburg.[3] As of 2007, the town had been county seat for 249 of the last 250 years.[4]

Loudoun County is included in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area.

As of 2011, Loudoun County had a median household income of $119,134. The county has been ranked number one in median household income since 2007 for jurisdictions in the United States with a population of 65,000 or more.[5]


Loudoun County was established in 1757 from Fairfax County. The county is named for John Campbell, Fourth Earl of Loudoun and Governor General of Virginia from 1756–59.[1] Western settlement began in the 1720s and 1730s with Quakers, Scots-Irish, Germans and others moving south from Pennsylvania and Maryland and by English and African slaves moving upriver from Tidewater.

By the time of the American Revolution, it was the most populous county in Virginia. In addition, it was rich in agriculture. During the American Revolution, it contributed much of its grain to George Washington’s Continental Army, earning it the nickname “Breadbasket of the Revolution.”[6] During the War of 1812, important Federal documents and government archives were evacuated from Washington and stored at Leesburg for safe keeping. Local tradition holds that these documents were stored at Rokeby House and thus that Leesburg was briefly the capital of the United States.

Early in the American Civil War, the Battle of Balls Bluff took place near Leesburg on October 21, 1861. Future jurist Oliver Wendell Holmes, Jr. was critically wounded in that battle along the Potomac River. During the Gettysburg Campaign in June 1863, Confederate Major General J.E.B. Stuart and Union cavalry clashed in the battles of Aldie, Middleburg, and Upperville. Confederate partisan John S. Mosby based his operations in Loudoun and adjoining Fauquier County (for a more in-depth account of the history of Loudoun County during the Civil War, see Loudoun County in the American Civil War).

In 1962, Washington Dulles International Airport was built in southeastern Loudoun County in Sterling. Since then, Loudoun County has experienced a high-tech boom and rapid growth. Accordingly, many have moved to eastern Loudoun and become residents of planned communities such as Sterling Park, Sugarland Run, Cascades, and Ashburn Farms, making that section a veritable part of the Washington suburbs. Others have moved to the county seat or to the small towns and rural communities of the Loudoun Valley.[6]

Loudoun County was traditionally one of the most Republican-leaning counties in Northern Virginia[citation needed]. Prior to the 2008 election, it had not voted for a Democrat for President since Lyndon B. Johnson in 1964. In recent years, however, the county has experienced rapid growth in its eastern portion, driven mainly by commuters drawn by the close proximity to Washington, D.C. This has made Loudoun more competitive. Nevertheless, after giving Senator Barack Obama nearly 54% of its presidential vote in 2008, the county shifted back to the GOP in 2009; Republican Robert F. McDonnell received 61% of the gubernatorial vote. Voters also removed two incumbent Democratic delegates, making Loudoun's state House delegation all-Republican. Loudoun shifted back to the Democrats in 2012 in the presidential election, as Obama recaptured the county with 51.5%, with Republican challenger Mitt Romney garnering 47%.[7]

Like many counties in Virginia, Loudoun is governed by a board of supervisors, the Loudoun County Board of Supervisors. The Chairman of the Board is elected by county voters at-large while the remaining supervisors are elected from each of eight electoral districts. All nine members serve concurrent terms of four years. While the board handles policy issues and sets the budget, day-to-day operations of the county government are handled by a County Administrator appointed by the board. The 2003 board, among other officials in Loudoun, was the subject of a federal investigation of possible corruption relating to a land deal involving the Royal Saudi Academy.[8]

In November 2007 voters removed four incumbent, fiscally conservative Republicans from the existing Board of Supervisors in a backlash over rapid development in the eastern portion of the county. The make-up of the board following the election was five Democrats, two Republicans, and two Independents.[9]

In November 2011, Republicans were elected to all nine seats on the Board.[10] The current Chairman is Scott K. York and the current Vice-Chairman is Janet Clarke, the Blue Ridge District Supervisor.

Secession movement[edit]

Due to the increasing differences between eastern and western Loudoun, some residents of western Loudoun,[who?] have advocated for western Loudoun to secede and form a new county.[11] This new county would be called Catoctin County, Virginia.[12] Its county seat would be Purcellville,[13] which is the largest and most developed town in western Loudoun.


The scenic byways of Loudoun County are spotted with historical structures dating back to before the American Civil War.

According to the U.S. Census Bureau, Loudoun County has a total area of 521 square miles (1,350 km2), of which 516 square miles (1,340 km2) is land and 6 square miles (16 km2) (1.1%) is water.[14] It is bounded on the north by the Potomac River; across the river are Frederick, Washington and Montgomery counties in Maryland; it is bounded on the south by Prince William and Fauquier counties, on the west by watershed of the Blue Ridge Mountain across which are Jefferson County, West Virginia and Clarke County, and on the east by Fairfax County. The Bull Run Mountains and Catoctin Mountain bisect the county. To the west of the range is the Loudoun Valley. Bisecting the Loudoun Valley from Hillsboro to the Potomac River is Short Hill Mountain.

Street addresses[edit]

Block numbers in the unincorporated areas of Loudoun County, with the exception of older Sterling Park and the community of CountrySide, are assigned in the following manner: on north-south streets, block numbers increase from north to south and range from 10000 to 27000; on east-west streets, block numbers increase from west to east and range from 30000 to 48000.[15]

It is home to world headquarters for several Internet-related and high tech companies, including Verizon Business, Telos Corporation, Orbital Sciences Corporation, and Paxfire. Like Fairfax County's Dulles Corridor, Loudoun County has economically benefited from the existence of Washington Dulles International Airport, the majority of which is located in the county along its border with Fairfax.

Before its dissolution, Independence Air (originally Atlantic Coast Airlines) was headquartered in Dulles.[23][24] At one time Atlantic Coast Airlines had its headquarters in Sterling.[25] Prior to its dissolution, MAXjet Airways was headquartered on the grounds of Washington-Dulles International Airport.[26]
