2. The Five Families of New York

The notorious Five Families—Bonanno, Colombo, Gambino, Genovese, and Lucchese—have been the backbone of the New York Mafia since the 1930s. These powerful clans orchestrated elaborate racketeering schemes, infiltrating labor unions and legitimate businesses alike. Their reach extended far beyond New York, influencing organized crime throughout the United States. With secret alliances and brutal rivalries, their operations became legendary in both law enforcement circles and popular culture.
