After moving to Chicago with his family in 1955, Hoover joined a gang of 50 older youths called the 'Supreme Gangster Nation. They hung around the corner of 68th and Green Street in the Englewood neighborhood on the South Side of Chicago where Hoover lived. Hoover was kicked out of high school on the first day of his sophomore year after being shot in the thigh by a rival gang member in 1965.
In 1974, after the death of David Barksdale, Hoover was appointed the new leader of the BDGN. Two years later, Jerome "Shorty" Freeman (who was a candidate for the Nation's presidency) left the BGDN, making the Black Disciples and the Black Gangster Disciples separate gang organizations. Even in prison, Hoover gave orders to his gang members and directed their illegal drug trade. On July 22, 1978, an inmate riot at the Pontiac Correctional Center in Illinois resulted in the death of three corrections officers. This uprising was rumored to have been ordered by Hoover. 21 inmates were indicted; ten were acquitted after an 11-week trial. Charges against Hoover and seven others were eventually dropped.
Hoover and the leaders of other gang organizations in Chicago came together to form the F.O.L.K.S. alliance, a pact meant to settle disputes and instill a more peaceful environment behind prison walls and on the streets. Hoover may not have been totally responsible for its creation as some suggest; at the time the largest gang in the alliance was the Simon City Royals, a white gang. Hoover is the leader of the GD's, not all Folks. However in the present year the GD's are now the largest gang in the Folk Nation having over an estimated 300,000 members world-wide
