Salvatore Maranzano
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. After one of Masseria's lieutenants Gaetano Reina switched sides to Maranzano, Masseria ordered Luciano to arrange Reina's murder. After Reina was murdered on February 26, 1930, the rivalry between Masseria and Maranzano escalated into the bloody Castellammarese War.
