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.
J. Edgar Hoover
The Apalachin Meeting of late 1957 embarrassed the FBI by proving on newspaper front pages that a nationwide Mafia syndicate thrived unimpeded by the nation's "top cops." Hoover immediately changed tack, and during the next five years, the FBI investigated organized crime heavily. Its concentration on the topic fluctuated in subsequent decades, but it never again merely ignored this category of crime.
