The Attica Prison riot occurred at the Attica Correctional Facility in Attica, New York, United States in 1971. This riot is one of the most famous and important riots during the Prisoners' Rights Movement. The riot was based upon prisoners' demands for political rights and better living conditions. On September 9, 1971, two weeks after the killing of George Jackson at San Quentin, about 1,000 of the Attica prison's approximately 2,200 inmates rebelled and seized control of the prison, taking 42 staff hostage.
