After Maranzano's death, Bonnano became boss–or as he called himself, "Father"–of the bulk of Maranzano's family. At the age of 26, Bonanno became one of the youngest-ever bosses of a crime family. Bonanno's role in the events leading up to Maranzano's death has been disputed. Years later, Bonanno wrote in his autobiography that he did not know about Luciano's plans; he claimed to have only learned about them from Magaddino. According to Bonanno, he subsequently learned that Maranzano and Luciano had had a falling out over influence in the Garment District. Reportedly, relations between the two had soured to the point that Maranzano was planning to kill Luciano as early as one day after Maranzano was ultimately assassinated. Maranzano had given the contract to Irish gangster Vincent "Mad Dog" Coll, who was actually on his way to Maranzano's office on the day of Maranzano's death. According to Bonanno, he concluded that going to war with Luciano would serve no purpose, since Luciano only wanted to be left alone to run his own rackets and "demanded nothing from us." He also believed that his soldiers would not be enthused about going to the mattresses again so soon after the end of the Castellamarese War. For this reason, Bonanno said, he decided to choose "the path of peace." However, according to mob expert Anthony Bruno, it "defies mob logic" to believe that Luciano would have allowed Bonanno to stay alive had Bonanno still supported Maranzano.
