Outwardly, the Castellammarese War was between the forces of Masseria and Maranzano. Underneath, however, there was also a generational conflict between the old guard Sicilian leadership known as the "Mustache Petes" for their long mustaches and old-world ways, such as refusing to do business with non-Italians and the "Young Turks", a younger and more diverse Italian group who were more forward thinking and willing to work more with non-Italians. This approach led his followers to question whether Masseria was even capable of making the Mafia prosper in the modern times. Led by Luciano, the aim of this group was to end the war as soon as possible in order to resume their businesses, because they viewed the conflict as unnecessary. Luciano's objective was to modernize the mob and do away with unnecessary orthodox norms. This was a vision that enabled him to attract followers, who had seen the inadequacies of Masseria's traditionalist leadership. Therefore, both factions were fluid, with many mobsters switching sides or killing their own allies during the war. Tensions between the Maranzano and Masseria factions were evident as far back as 1928, with one side frequently hijacking the other's alcohol trucks (alcohol production was then illegal in the United States due to Prohibition).
