Mafia
Masseria was shot to death in a restaurant in New York by Maranzano's soldiers; one of them was Vito Genovese, a man who would later become boss. That was also the end of the "Castellammarese War." With the death of Masseria, Maranzano appointed himself the boss of the New York Mafia, who was called in Italian the Capo di tutti Capi, meaning "Boss of all Bosses." He called a meeting with the other "mafiosi" (Italian for Mafia members) from all over the US and made the rules that are still used today.
