Inmates at Attica Correctional Facility seized control for four days, ending in a violent state retaking that killed 43 people.

On September 9, 1971, approximately 1,000 inmates at Attica Correctional Facility in upstate New York seized control of the prison, taking 42 staff members hostage. The prisoners issued demands for better living conditions and political rights. After four days of negotiations, Governor Nelson Rockefeller ordered state police to retake the facility by force. In the assault, 29 inmates and 10 hostage-civilian employees were killed, nearly all by police gunfire. The Attica riot became a rallying point for prison reform and remains one of the deadliest prison uprisings in U.S. history.
