One of the worst racial tragedies in American history occurred in Tulsa in 1921. A young Black man accidentally steps on the foot of a young white woman elevator operator. She screams. A lynch mob forms and Blacks come to protect the young man. A riot erupts which destroys 36 square blocks of the country's most successful Black neighborhood. Hundreds of Blacks die and thousands lose their property and homes. The history is buried for years. The issues that result are still unresolved.
