The Tulsa Race Massacre, also known as the Tulsa Race Riot, took place in the Greenwood district of Tulsa, Oklahoma, in late May and early June of 1921. Greenwood was a prosperous African American community known as "Black Wall Street" due to its flourishing businesses and wealth.

The massacre was sparked by a false accusation against a young Black man named Dick Rowland, who was accused of assaulting a white woman in an elevator. A white mob gathered outside the courthouse where Rowland was held, and tensions escalated quickly.

On May 31, 1921, the white mob descended on Greenwood, looting, burning homes, businesses, and churches, and attacking Black residents. The violence lasted for two days, during which an estimated 300 African Americans were killed, and thousands were left homeless as over 35 blocks of the community were destroyed.

The massacre was largely ignored and downplayed in mainstream history for decades. It was only in recent years that efforts have been made to uncover and acknowledge the full extent of the devastation and trauma caused by the Tulsa Race Massacre. It remains one of the most tragic and horrific incidents of racial violence in American history.
