Salvatore Maranzano
After decades of battles between the Sicilians and Neapolitan Camorra, the Sicilian Mafia became the dominant force in gambling, labor, and bootlegged liquor. By the 1930s, two major factions fought for dominance – Stefano Magaddino from Niagara Falls was a senior member of the Castellammarese families, one of the factions. Led by Salvatore Maranzano in Brooklyn, the Mafia from Castellammare del Golfo levied a war against Joe 'the boss' Masseria in Manhattan, ending in the latter's murder. Salvatore Maranzano and Charlie 'Lucky' Luciano were the winners of the Mafia feud and called the heads of families from across the nation to meet and discuss the re-organization of the Mafia. Families from diverse locations were to gather in Chicago and hear how Salvatore Maranzano defeated Joe Masseria with the help of Lucky Luciano; they were to hear a new structure for organized crime in the nation that was destined to change the face of the Mafia.
