The Memphis massacre of 1866 was a series of violent events that occurred from May 1 to 3, 1866 in Memphis, Tennessee. The racial violence was ignited by political and social racism following the American Civil War, in the early stages of Reconstruction. After a shooting altercation between white policemen and black veterans recently mustered out of the Union Army, mobs of white residents and policemen rampaged through black neighborhoods and the houses of freedmen, attacking and killing black soldiers and civilians and committing many acts of robbery and arson.
