Castellammarese 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.
