The Greensboro massacre was a deadly confrontation which occurred on November 3, 1979, in Greensboro, North Carolina, US, when five protesters, including four members of the Communist Workers Party (CWP), were killed by members of the Ku Klux Klan and the American Nazi Party (ANP) during a Death to the Klan march, organized by the CWP. The event had been preceded by inflammatory rhetoric from both sides. The CWP had originally come to Greensboro to support workers' rights activism among mostly black textile industry workers in the area. The march was a part of that larger effort. The Greensboro city police department had an informant within the KKK and ANP group who notified them that the Klan was prepared for armed violence.
