The Black Disciples gang was formed in Chicago in 1974 by David Barksdale and has since expanded to over 300 factions across the country. As one of the largest and most violent street gangs in America, they are heavily involved in drug dealing and have developed their own unique language used in graffiti. The Black Disciples operate under various names including Devil's Disciples, Falcon Disciples, and others that control different territories in Chicago and beyond.
