Castellammarese War

Luciano soon became a top aide in Masseria's criminal organization. In contrast to Rothstein, Masseria was uneducated, with poor manners and limited managerial skills. By the late 1920s, Masseria's main rival was boss Salvatore Maranzano, who had come from Sicily to run the Castellammarese clan. Maranzano refused to pay commissions to Masseria. Their rivalry eventually escalated into the bloody Castellammarese War and ultimately resulted in the deaths of both Maranzano and Masseria.
