Salvatore Maranzano
Masseria soon became embroiled in the vicious Castellammarese War with his archrival, Salvatore Maranzano. Maranzano represented the Sicilian clans, most of which came from Castellammare del Golfo, Sicily. As the war progressed, both bosses started recruiting more soldiers. By 1930, Adonis had joined the Masseria faction. As the war turned against Masseria, Luciano secretly contacted Maranzano about switching sides. When Masseria heard about Luciano's betrayal, he approached Adonis about killing Luciano. However, Adonis instead warned Luciano about the murder plot.
