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.
North Side Gang
After the death of Dean O'Banion, Hymie Weiss assumed leadership of the North Side Gang and immediately struck back at his rivals. On January 12, 1925, Weiss, Bugs Moran, and Vincent Drucci, attempted to kill Torrio's lieutenant, Al Capone at a Chicago South Side restaurant. Firing at Capone's car, the men wounded chauffeur Sylvester Barton, but missed Capone entirely. Capone, startled by the shooting, ordered his famous armoured car to be created. Moran then decided to kidnap one of Capone's trusted bodyguards, torture him for information before finally executing him and dumping the body.
