The Gangster Disciple Nation (often abbreviated as the GDs; formally GDN, or simply Gangster Disciples), also known as Growth & Development, is an African-American street- and prison-gang founded by former rivals David Barksdale (1947-1974) and Larry Hoover (1950- ); in 1968, the two came together to form the Black Gangster Disciple Nation (BGDN).
Post-1989, following growing tension between its component parts, the BGDN split into two new factions: Larry Hoover's Gangster Disciple Nation (GDN) and the Black Disciple Nation (BDN). As of 2022, following Hoover's departure, the GDN has no full-time gang leader.
