The Black Wall Street of Greenwood, Tulsa, OK, was the most successful business district African-Americans have ever created, built in the early 20th Century. In 1926, it was burned to the ground in the Tulsa "Race Riot."
At the start of the 20th century, a wealthy African-American businessman named O.W. Gurley bought 40 acres of land which was "only to be sold to colored". Over time, businessmen bought up the land and set up shop, and the Greenwood area became known as the Black Wall Street.
During the Tulsa Race Riot in 1926., a KKK-led mob destroyed Black Wall Street.
