The Black Panther Party (originally the Black Panther Party for Self-Defense) was an African-American revolutionary leftist organization. It was active in the United States from 1966 until 1982. The Black Panther Party achieved national and international notoriety through its involvement in the Black Power movement and in U.S. politics of the 1960s and 70s. The anti-racism of that time is today considered one of the most significant social, political and cultural currents in U.S. history. The group's "provocative rhetoric, militant posture, and cultural and political flourishes permanently altered the contours of American Identity."
