The 1921 #TulsaRaceMassacre was a state-sanctioned terrorist attack on the thriving Black community of Greenwood in Tulsa, Oklahoma. We must never forget what happened on May 31, 1921. We mourn with the descendants and continue to remember the dangers of white supremacy, which is still prevalent today. #blackhistory #americanhistory #didyouknow #otd #tulsa
