The Black Panther Party (BPP), originally the Black Panther Party for Self-Defense, was a political organization founded by Bobby Seale and Huey Newton in October 1966 in Oakland, California. The party was active in the United States from 1966 until 1982, with chapters in numerous major cities, and international chapters operating in the United Kingdom in the early 1970s, and in Algeria from 1969 until 1972.
At its inception on October 15, 1966, the Black Panther Party's core practice was its armed citizens' patrols to monitor the behavior of officers of the Oakland Police Department and challenge police brutality in the city. In 1969, community social programs became a core activity of party members. The Black Panther Party instituted a variety of community social programs, most extensively the Free Breakfast for Children Programs, to address issues like food injustice, and community health clinics for education and treatment of diseases including sickle cell anemia, tuberculosis, and later HIV/AIDS. The party enrolled the most members and had the most influence in the Oakland-San Francisco Bay Area, New York, Chicago, Los Angeles, Seattle, and Philadelphia. There were active chapters in many prisons, at a time when an increasing number of young African-American men were being incarcerated.
Federal Bureau of Investigation Director J. Edgar Hoover described the party in 1969 as "the greatest threat to the internal security of the country." He developed and supervised an extensive counterintelligence program (COINTELPRO) of surveillance, infiltration, perjury, police harassment, and many other tactics designed to undermine Panther leadership, incriminate party members, discredit and criminalize the Party, and drain the organization of resources and manpower. The program was also accused of assassinating Black Panther members, including Fred Hampton.
Black Panther Party members were involved in many fatal firefights with police: Huey Newton allegedly killed officer John Frey in 1967, and Eldridge Cleaver led an ambush in 1968 of Oakland police officers, in which two officers were wounded and Panther Bobby Hutton was killed. The party suffered many internal conflicts, resulting in the murders of Alex Rackley and Betty Van Patter.
Government oppression initially contributed to the party's growth, as killings and arrests of Panthers increased its support among African Americans and on the broad political left. Both groups valued the Panthers as a powerful force opposed to de facto segregation and the military draft. Black Panther Party membership reached a peak in 1970, with offices in 68 cities and thousands of members; it began to decline over the following decade. After the 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, caused 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 appeared detailing the group's involvement in illegal activities, such as drug dealing and extortion schemes directed against 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 lasted longer than most, with a breakfast program and medical clinics that continued even after the chapter disbanded in 1977. Party contractions continued throughout the 1970s, and by 1980, the Black Panther Party had just 27 members.
The history of the Black Panther Party is controversial. Scholars have characterized the Black Panther Party as the most influential black movement organization of the late 1960s, and "the strongest link between the domestic Black Liberation Struggle and global opponents of American imperialism". Other commentators have described the Party as more criminal than political, characterized by "defiant posturing over substance".
