Salvatore Maranzano
In 1930, violence broke out between a faction led by Giuseppe "Joe the Boss" Masseria and members of the Castellamarreses over the theft of Masseria's bootleg liquor. This soon developed into a full out war known as the Castellammarese War. At the time, the Castellammareses were led by Nicolo "Cola" Schirò, who tried to work with Masseria. Schirò was replaced by Salvatore Maranzano, who wanted to take control over New York's underworld. Under his leadership, the bloodshed continued.
