On this day in 1921, the black district of Tulsa, Oklahoma, was destroyed by a white mob. The Greenwood district of Tulsa had one of the most affluent black communities in the United States at this time, earning the nickname ‘Black Wall Street’. On May 30th 1921, a young black man called Dick Rowland rode in an elevator with a white woman; false rumours swirled in the white community that Rowland had attempted to assault her. Rowland was arrested on May 31st, and sensationalist newsaper coverage of the incident fuelled talk of lynching. This led to a confrontation between white and black mobs outside the courthouse, which resulted in a gun being discharged, sparking violence. The following day, June 1st, the Greenwood District was looted and burned by white rioters. The governor declared martial law, and National Guard troops were called to quell the violence. Law enforcement officials imprisoned black Tulsans, with over 6,000 people held for days on end; most white rioters, in contrast, were not arrested. In the wake of the violence, 35 city blocks lay in ruins, thousands of African-Americans were left homeless, and over 800 people had been injured. The dead were buried in mass graves, with the toll initially placed at 36, but revised by a 2001 report which rose the estimation to 300 fatalities. This report, which recommended paying reparations to the survivors and victims’ families, was part of a concerted effort in recent years to end the silence about the event. The scale of the violence was covered up at the time, and the incident was omitted from state and national histories. The Tulsa riot was one of a number of attempted ‘racial cleansings’ by white mobs against black communities in the United States, which had the tacit support of law enforcement and government. It is vital that this event, which saw white mobs destroy an entire black neighborhood, is remembered and placed in the long narrative of systemic racism in the United States.
