The Tulsa Race Massacre of 1921 began in downtown Tulsa, moved through the city’s main commercial area where skirmishes and other confrontations broke out on the streets and sidewalks, and ultimately spilled across the Frisco Tracks into the Greenwood neighborhood where the most intense fighting and arson took place. In less than a 24 hour period over 300 African American residents and business owners were killed and over 1200 homes along with nearly every other building including churches, schools, businesses, a hospital and a library located in the district were destroyed in what has been called the single worst incident of racial violence in American history.
