The Five Families originated out of New York City Sicilian Mafia gangs. They were formally organized in the summer of 1931 by Salvatore Maranzano after the April 15, 1931, murder of Giuseppe Masseria, in what has become known as the Castellammarese War. Maranzano also introduced the now familiar Mafia hierarchy: Boss (Capofamiglia), Underboss (Sotto capo), Advisor (Consigliere), Captain (Caporegime), Soldier (Soldato), and Associate; and declared himself capo di tutti capi (boss of bosses). By declaring himself "boss of bosses," Maranzano reneged on the deal he had made with Lucky Luciano. In that deal, it was agreed that after Luciano was to help murder Masseria, the two bosses were to be equals. When Maranzano was murdered just months after Masseria on September 10, 1931, the "Boss of Bosses" position was eliminated in favor of The Commission, a council which demarcated territory among the previously warring factions and governs American Mafia activities in the United States and Mexico.
1991 – Rastelli dies of cancer and underboss Joseph Massino becomes boss. Massino eventually changes the family's name to the Massino crime family.
2003–2004 – Massino is arrested and convicted of racketeering and murder charges. Massino became a federal witness, testifying against 60 fellow mobsters, so acting bosses Anthony "Tony Green" Urzo and Michael "Mikey Nose" Mancuso, both of whom were themselves jailed, controlled the family briefly.
2005–present – Vincent "Vinny Gorgeous" Basciano moves up from Acting Boss to become Boss. Authorities contend that Basciano continues to lead the family from prison in Colorado, where he is serving two life sentences for murder convictions in 2006 and 2011.
1931 – Joseph Profaci has his Brooklyn-based gang formally recognized as a family.
1964 – Magliocco is forced to retire after taking part in Bonanno's plot to take over the Commission. Joseph Colombo becomes new boss with Commission support and changes the family's name.
1971 – Colombo is shot and paralyzed at a civil rights rally he organized. Colombo's activism drew unwanted publicity and attention towards the Mafia, and made other Mafia leaders, such as Carlo Gambino, uneasy. The first rally Colombo organized attracted over 50,000 people with Gambino's support; the second rally barely drew 10,000 people without Gambino's blessing. It was theorized that the Commission authorized Colombo's murder to take pressure off of the Mob. The most likely candidate, though, was Joseph "Crazy Joe" Gallo.
1986 – Persico is convicted on racketeering charges and sentenced to life in prison.
1986–2004 – Persico tries to run the family from prison until his son, Alphonse "Little Allie Boy" Persico, can succeed him. Persico's son is convicted and put in jail.
1931 – Vincent Mangano becomes boss of the newly formed Mangano crime family.
1951 – Mangano disappears, presumably murdered by underboss Albert "the Executioner" Anastasia. With Commission support, Anastasia then assumes title of boss, and the family assumes his name. Vito Genovese, underboss of the Luciano family, believed that Anastasia had broken a cardinal Mafia rule by murdering Mangano. However, war was avoided between the two families due to the efforts of Joe Bonanno. Genovese still resented Anastasia, though, and Genovese would cultivate the sympathies of Anastasia's underboss Carlo Gambino.
1957 – Anastasia is assassinated by gunmen in a barber shop, with Genovese and Gambino being prime suspects for orchestrating the murder. Gambino takes over as boss, and the family assumes his name.
1976 – Gambino dies of a heart attack; he is succeeded as boss by his brother-in-law "Big" Paul Castellano.
1985 – Castellano is gunned down and John Gotti, the man responsible for planning Castellano's assassination, becomes boss.
2002 – Gotti dies of cancer in prison after being convicted of RICO charges in 1992. His brother, Peter, succeeds him as boss.
2003–2004 – Peter Gotti is convicted on racketeering charges.
2011 – Sicilian mobster Domenico Cefalu is appointed boss in a return to tradition.
1957 – Costello goes into retirement after a failed assassination attempt orchestrated by Vito Genovese. Genovese then replaces Costello and renames the family. Genovese's motive for removing Costello had to do with the fact that Genovese was Luciano's underboss and, in his mind, the rightful heir to Luciano's position. Genovese, however, fled to Italy to evade murder charges, making him an unsuitable candidate for the title of boss, which left Luciano no choice but to bestow the title on Costello.
1969 – Genovese dies in prison still as boss after being convicted of narcotics trafficking charges in 1959, and Philip "Benny Squint" Lombardo becomes new Genovese boss.
1980s – Lombardo retires and is replaced by Vincent "Chin" Gigante, the man who attempted to assassinate Frank Costello in 1957.
1997–2005 – Gigante is convicted on racketeering charges and dies in prison.
1967 – Lucchese dies of a brain tumor, temporarily leaving the family leaderless. The Commission selects Carmine Tramunti to fill in as acting boss until the leading candidate for the position of boss, Anthony Corallo, was released from prison.
1970 – Anthony "Tony Ducks" Corallo becomes the new boss. Some contend that the position was not formalized until 1973, when Tramunti was imprisoned, and that between 1970 and 1973, Tramunti remained family boss, but only in name, with Corallo actually in control.
1986 – Corallo implicates himself and many other mobsters in recorded conversations. He is convicted of RICO charges, along with top mobsters of the Genovese, Gambino, and Colombo families, and sentenced to life in prison. Before being incarcerated, Corallo selected Vittorio "Little Vic" Amuso and Anthony "Gaspipe" Casso as the two candidates most deserving of the title of boss.
1987 – Amuso becomes boss after being nominated by Casso, but Casso, as underboss, is viewed as the man who makes important decisions and has control of the family.
1992 – Amuso is sentenced to life in prison after being convicted of racketeering charges.
1998 – Casso is sentenced to life in prison after pleading guilty to racketeering and murder charges. Louis "Louie Bagels" Daidone becomes acting boss.
