I enjoyed reading all the details about each event, surprisingly this time you didn't feel like elaborating more on this event. So I went to Wikipedia.....
The Tulsa race massacre (known alternatively as the Tulsa race riot, the Greenwood Massacre, the Black Wall Street Massacre, the Tulsa pogrom, or the Tulsa Massacre) took place on May 31 and June 1, 1921, when mobs of white residents, many of them deputized and given weapons by city officials, attacked black residents and businesses of the Greenwood District in Tulsa, Oklahoma. It has been called "the single worst incident of racial violence in American history."The attack, carried out on the ground and from private aircraft, destroyed more than 35 square blocks of the district—at that time the wealthiest black community in the United States, known as "Black Wall Street."
