Black Panther Party membership reached a peak in 1970, with offices in 68 cities and thousands of members, but it began to decline over the following decade. After its leaders and members were vilified by the mainstream press, public support for the party waned, and the group became more isolated. In-fighting among Party leadership, fomented largely by the FBI’s COINTELPRO operation, led to expulsions and defections that decimated the membership. Popular support for the Party declined further after reports of the group’s alleged criminal activities, such as drug dealing and extortion of Oakland merchants. By 1972 most Panther activity centered on the national headquarters and a school in Oakland, where the party continued to influence local politics. Though under constant police surveillance, the Chicago chapter also remained active and maintained their community programs until 1974. The Seattle chapter persisted longer than most, with a breakfast program and medical clinics that continued even after the chapter disbanded in 1977. The Party continued to dwindle throughout the 1970s, and by 1980 had just 27 members.
