Castellammarese War

Italian-American Mafia war

The Castellammarese War (Italian pronunciation: [kaˌstɛllammaˈreːze, -eːse]) was a bloody power struggle for control of the American Mafia between partisans of Joe "The Boss" Masseria and Salvatore Maranzano in New York City from February 26, 1930, until April 15, 1931. The feud was named after the Sicilian town of Castellammare del Golfo, Maranzano's birthplace.

Maranzano's faction prevailed in the conflict and divided New York's crime families into the Five Families. Maranzano declared himself capo di tutti i capi ("boss of all bosses"). Maranzano was murdered in September 1931 on orders of Lucky Luciano, who established a power-sharing arrangement through a governing body called the Commission, giving equal stature to all Mafia families to avoid such feuds in the future.
