In the late 1920s, the most important and profitable
Mafia operations in the United States were controlled by
Giuseppe "Joe The Boss" Masseria in
New York City. Masseria emerged as the most powerful gangster in the city after the 1928 killing of his main rival
Salvatore D'Aquila, following a protracted gang war. In 1929, Masseria began applying pressure to other mafia gangs in the city for monetary tributes, and established alliances with Mafia groups from outside of New York. His faction consisted mainly of gangsters from
Sicily,
Calabria (the
'Ndrangheta) and
Campania (the
Camorra) in southern Italy. Masseria's faction included
Charles "Lucky" Luciano,
Albert "Mad Hatter" Anastasia,
Vito Genovese,
Alfred Mineo,
Willie Moretti,
Joe Adonis and
Frank Costello. However, powerful Sicilian
Don Vito Ferro decided to make a bid for the control of Mafia operations, sending
Salvatore Maranzano from his base in
Castellammare del Golfo to seize control. The Castellammarese faction in the U.S. included
Joseph "Joe Bananas" Bonanno,
Stefano "The Undertaker" Magaddino,
Joseph Profaci and
Joe Aiello. As part of his attempts to consolidate control in New York, Joe Masseria forced the resignation of Castellammarese boss
Nicolo Schiro. Soon after, he organized the murder of his close ally
Vito Bonventre, who was killed at his home on July 15, 1930. This led to Maranzano being elevated to boss of the gang, setting the stage for an open confrontation with Masseria. As it became more evident that the two factions would clash for the leadership of the Mafia, they each sought to recruit more followers to support them. Outwardly, the Castellammarese War was between the forces of Masseria and Maranzano. Underneath, 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-American group who, unlike the "Mustache Petes", had grown up in the U.S., were more forward-thinking and were willing to work with non-Italians. While Masseria was powerful and respected, his aggressive expansion made turf wars inevitable. This approach led to several of Masseria's followers to question whether he was capable of making the Mafia prosper in the world of the 1930s. Led by Luciano, the aim of this group was to end the feud as soon as possible in order to resume their businesses, viewing the conflict as unnecessary. Luciano's objective was to modernize the mob and do away with unnecessary orthodox norms. This vision enabled Luciano to attract followers, who saw the inadequacies of Masseria's traditionalist leadership. Therefore, both factions were fluid, with many mobsters switching sides or killing their own allies during the feud. Tensions between the Masseria and Maranzano factions were evident as far back as 1928, with one side frequently
hijacking the other's alcohol trucks, with alcohol production being illegal in the U.S. at that time due to
Prohibition. ==Hostilities begin==
