The Greensboro massacre occurred on November 3, 1979 in Greensboro, North Carolina, United States. Five protest marchers were shot and killed by members of the Ku Klux Klan and the American Nazi Party. The protest was the culmination of attempts by the Communist Workers Party to organize mostly black industrial workers in the area.
