During the Castellammarese War, between 1930 and 1931, Maranzano and Bonanno fought against a rival group based in Brooklyn, led by Joe Masseria and Giuseppe Morello. However, a third, secret, faction soon emerged, composed of younger mafiosi on both sides. These younger mafiosi were disgusted with the old-world predilections of Masseria, Maranzano and other old-line mafiosi, whom they called "Mustache Petes." This group of "Young Turk" mafiosi was led by Masseria's second-in-command, Lucky Luciano, and included Frank Costello, Vito Genovese, Joe Adonis, Carlo Gambino and Albert Anastasia on the Masseria side and Joe Profaci, Tommy Gagliano, Tommy Lucchese, Joseph Magliocco and Stefano Magaddino on the Maranzano side. Although Bonanno was more steeped in the old-school traditions of "honor", "tradition", "respect" and "dignity" than other mafiosi of his generation, he saw the need to modernize and joined forces with the Young Turks.
