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.
Sam Giancana
Giancana was present at the Mafia's 1957 Apalachin meeting at the Upstate New York estate of Joseph Barbara. Later, Buffalo crime boss Stefano Magaddino and Giancana were overheard by wiretap saying the meeting should have occurred in the Chicago area. Giancana claimed that the Chicago area was "the safest place in the world" for a major underworld meeting because he had several police chiefs on his payroll. If the syndicate ever wanted to hold a meeting in or around Chicago, Giancana said, they had nothing to fear because they had the area "locked up tight".
