The Black Mafia, also known as the Philadelphia Black Mafia (PBM), Black Muslim Mafia and Muslim Mob, was a Philadelphia-based African-American organized crime syndicate. The organization began as a small criminal collective, known for holding up neighborhood crap games and dealing in the illegal drug business, but at its height of operation until about 1975, it managed to consolidate power and control a large portion of criminal activity in various African-American neighborhoods throughout Philadelphia, the Delaware Valley, and South Jersey, including Atlantic City and Camden. In addition to drug trafficking, burglary, and armed robbery, the Black Mafia was also engaged in traditional organized crime activities such as extortion, racketeering, prostitution, loansharking, number running and other illegal gambling rackets.
