Tulsa, Oklahoma
This happened in Tulsa's Greenwood District. It was the wealthiest black community in the US at the time, a thriving and prosperous entrepreneurial area which had earned a reputation as the Black Wall Street of America. The white community gathered in a lynch mob after a young black boy was accused of assaulting a white girl in a lift. The two days resulted in a bloodbath, more than 1,400 businesses and homes were looted and fired, and the area was reduced to ash. Survivors would not talk of it for many years, media also largely kept quiet, and official National Guard reports plus photographs and a newspaper editorial at the time were collected and destroyed or appear to have gone missing.
