On Monday morning, September 13, 1971, an uprising by prison inmates of the Attica Correctional Facility, a maximum security prison located in western New York, ended in the bloodiest prison confrontation in American history. Five days earlier, thirteen hundred prisoners had rebelled, taken over the prison, and held forty guards hostage. Issuing a list of demands—including calls for improvements in living conditions as well as educational and training opportunities—they entered into negotiations with state officials. The negotiations failed and state police and national guard troops seized the prison; in the course of taking it over they killed forty-three individuals, including ten hostages.
