Photograph of the Greenwood District burning during the Tulsa Race Massacre

On May 31 and June 1, 1921, in Tulsa, Oklahoma, mobs of white residents brutally attacked the African American community of Greenwood, colloquially known as "Black Wall Street," in the deadliest racial massacre in U.S. history. Homes, businesses, and community structures including schools, churches, a hospital, and the library were looted and burned or otherwise destroyed. Exact statistics are unknown, but the violence left around 10,000 people homeless and as many as 300 people dead with many more missing and wounded.
