With the death of Masseria, the war ended. Maranzano organized the mafia in New York City using a clear structure and hierarchy by dividing the main Italian gangs in New York into Five Families. Each family with a boss, underboss, capos, soldiers, and associates. While associates could come from any background, the higher ranks had to be "made men", required in most eras to be full-blooded Italian Americans. Shortly after Masseria's death, Maranzano announced that the Five Families would be led by Luciano, Joe Bonanno, Joseph Profaci, Vincent Mangano and Thomas Gagliano.
