However, powerful Sicilian Don Vito Ferro decided to make a bid for control of Mafia operations. Masseria's faction included Charles 'Lucky' Luciano, Albert 'Mad Hatter' Anastasia, Vito Genovese, Alfred Mineo, Willie Moretti, Joe Adonis, and Frank Costello. In the 1920s, Mafia operations in the United States were controlled by Giuseppe 'Joe The Boss' Masseria, whose faction consisted mainly of gangsters from Sicily, along with Calabria (the 'Ndrangheta) and Campania (the Camorra) regions of southern Italy. However, Maranzano was murdered in September 1931 on orders of Lucky Luciano, who established a power-sharing arrangement called the Commission, a group of Mafia families of equal stature, to avoid such wars in the future.

Maranzano's faction won and divided New York's crime families into the Five Families Maranzano declared himself capo di tutti i capi ('boss of all bosses'). The war was named after the Sicilian town of Castellammare del Golfo, the birthplace of Maranzano. The Castellammarese War ( Italian pronunciation: ) was a bloody power struggle for control of the Italian-American Mafia that took place in New York City, New York, from February 1930 until April 15, 1931, between partisans of Joe 'The Boss' Masseria and those of Salvatore Maranzano.
