From Rap Dictionary
The Black Gangster Disciples Nation(oftenly shortened to the Ganster Disciples Nation) is a gang started in Chicago, Illinois in the 1960's. Their founders are Larry Hoover & David Barksdale. Before the BGD's got their start Larry Hoover was the leader of his own gang called the Supreme Gangsters & David Barksdale was also the leader of his own gang called the Black Disciples. They later united the ttwo gangs and called them the Black Gangster Disciples. The Gangster Disciples are under the Folk Nation along with other gangs such as the Imperial Gangsters, Gangster Two Six & La Raza Nation to name a few. Their biggest enemies are gangs under the People Nation such as the Almighty Latin King & Queen Nation & the Almighty Vice Lord Nation. Each gang in the Folk & People Nations have their own set of colors, Gangster Disciples original colors were black & blue but they stopped the wearing of the blue cause they didn't like being called Crips since they have nothing to do with each other(Crips are NOT apart of the Folk Nation), they now wear the colors black and gray.
