Tulsa race massacre, 1921
The Greenwood district of Tulsa, Oklahoma, was the scene of what was later described as one of the single worst incidents of racial violence in US history after mobs of white residents attacked their black neighbors and destroyed homes and businesses on May 31, 1921. An estimated 200 people of color lost their lives, as did around 50 white residents. A further 10,000 African Americans were left homeless.
