Sonny Corleone's gang was a small gang of stick-up artists led and founded by Sonny Corleone that was active in 1933 in New York City. The gang comprised Sonny and his closest friends. They regularly stole liquor shipments from other bootleggers, such as Mafia kingpin Giuseppe Mariposa, without the knowledge of Sonny's father, Don Vito, and often gave a cut to Luca Brasi and his outfit. This eventually led to the war between Mariposa and the Corleones. At this point the gang was incorporated into the Corleone family.
