The Commission (mafia)
After Maranzano's murder in 1931, the Mafia families called a meeting in Chicago. The purpose of the meeting was to replace the old Sicilian Mafia regime of "boss of all bosses" and establish a rule of consensus among the crime families. Charlie Luciano established a Mafia board of directors to be known as "The Commission" to oversee all Mafia activities in the United States and serve to mediate conflicts between families. The Commission consisted of seven family bosses: the leaders of New York's Five Families: Charlie "Lucky" Luciano, Vincent Mangano, Tommy Gagliano, Joseph Bonanno, and Joe Profaci; Chicago Outfit boss Al Capone; and Buffalo family boss Stefano Magaddino. Charlie Luciano was appointed chairman of the Commission. The Commission agreed to hold meetings every five years or when they needed to discuss family problems.
Louis Alterie
In the early 1920s, the North Side Gang's greatest rival was the Chicago Outfit, run first by John "The Fox" Torrio and then Al Capone. During this period a series of disputes over bootlegging territories and other matters led the North Siders into conflict with the Outfit and its allies, the Genna brothers of Little Italy. Alterie by some reports killed more than 20 Outfit and Genna gang members during this conflict which had erupted into a full-scale gang war in 1924 when O'Banion was murdered by Outfit gunmen in his floral shop on State Street in Chicago.
