The Attica Prison rebellions took place at the Attica Correctional Facility in Attica, New York in 1971. The rebellions were in response to inhumane treatment of the prisoners and horrid living conditions. The Attica rebellions were sparked by the killing of black activist George Jackson who was an inmate at San Quentin prison in California on August 21, 1971. It is estimated that about half of Attica prison's population of 2,200 inmates rebelled and seized control of the prison. Forty-two prison staff members were held by prisoners and four days of negotiations ensued. Authorities would agree to 28 of the prisoners' demands but would not agree to demands for complete amnesty from criminal prosecution for the prison takeover or for the removal of Attica's superintendent. When the uprising was over, at least 39 people were dead.
