Allegedly formed in September 1968 by Samuel Christian, who later adopted the name Suleiman Bey under the Nation of Islam, the Black Mafia was heavily involved in a large part of drug trafficking in Philadelphia during the 1970s, with heroin being the most trafficked drug. Christian, a former Black Panther with an extensive arrest record, was an imposing man: 5'10' tall and described as a "thick-necked, powerfully-built, 215-pound bully." Additional founding members included Ronald Harvey, Henry Dabney, Richard "Pork Chops" James, Donald "Donnie" Day, Clyde "Apples" Ross, Robert "Bop Daddy" Fairbanks, Craig "Heist" Jones, Walter Hudgins, Robert "Nudie" Mims amongst others. Many of the original members eventually became Nation of Islam members or converted to Islam, giving the organization the nickname of "the Muslim Mafia" or "the Muslim Mob."
