The 1906 Atlanta Race Massacre, also known as the 1906 Atlanta Race Riot, was an episode of mass racial violence against African Americans in the United States in September 1906. Violent attacks by armed mobs of White Americans against African Americans in Atlanta, Georgia, began after newspapers, on the evening of September 22, 1906, published several unsubstantiated and luridly detailed reports of the alleged rapes of 4 local women by black men. The violence lasted through September 24, 1906. The events were reported by newspapers around the world, including the French Le Petit Journal which described the "lynchings in the USA" and the "massacre of Negroes in Atlanta," the Scottish Aberdeen Press & Journal under the headline "Race Riots in Georgia," and the London Evening Standard under the headlines "Anti-Negro Riots" and "Outrages in Georgia." The final death toll of the conflict is unknown and disputed, but officially at least 25 African Americans and two whites died. Unofficial reports ranged from 10–100 black Americans killed during the massacre. According to the Atlanta History Center, some black Americans were hanged from lampposts; others were shot, beaten or stabbed to death. They were pulled from street cars and attacked on the street; white mobs invaded black neighborhoods, destroying homes and businesses.
