I didn’t see it but I heard about this in the last couple of years. According to google:
TULSA RACE MASSACRE.
Believed to be the single worst incident of racial violence in American history, the bloody 1921 outbreak in Tulsa has continued to haunt Oklahomans. During the course of eighteen terrible hours on May 31 and June 1, 1921, more than one thousand homes and businesses were destroyed, while credible estimates of deaths range from fifty to three hundred. By the time the violence ended, the city had been placed under martial law, thousands of Tulsans were being held under armed guard, and the state’s second-largest African American community had been burned to the ground.
To me this is one of the worst things that humans can do to another. 18 hours…..
You are welcome!

That is absolutely horrible I can only imagine what it must have been like to have endured what all those people went through. Hope I never have to go through that and thank you Phyllis for sharing your thoughts on this matter
