Alvin Hall tells the story of the 1921 Tulsa Race Massacre, one of the worst episodes of racial violence in US history. In the early 20th Century, Tulsa was a wild west town which became a boom city. But the oil capital of the world was also home to the thriving and prosperous district of Greenwood - nicknamed 'Black Wall Street' by Booker T Washington - because it was a mecca for Black entrepreneurs. On 30 May, a young Black shoe shiner Dick Rowland, was wrongly accused of attacking a white elevator operator Sarah Paige (the girl later recanted her story). This was the trigger, on 31 May and 1 June, for an armed white mob to loot and burn Greenwood, in a violent 16-hour attack. Many estimate up to 300 Black citizens were killed. Over 1200 homes were destroyed, every church, hotel, shop, and business was completely wiped off the map.
