The Tulsa Race Massacre, also known as the Tulsa Race Riot, was a devastating racial massacre that took place in the Greenwood district of Tulsa, Oklahoma in 1921. The Greenwood district was a prosperous African American community often referred to as "Black Wall Street" due to its economic success and vibrant cultural life.

The massacre began on May 31, 1921, after a young black man, Dick Rowland, was accused of assaulting a white woman in an elevator. The incident fueled tensions between the white and black communities, and a white mob gathered outside the courthouse demanding Rowland be turned over to them for lynching. When a group of black men arrived to protect Rowland, a shootout ensued, and violence quickly spread throughout the city.

Over the course of 18 hours, white mobs, including deputized civilians and even members of the National Guard, looted and set fire to businesses, homes, and churches in the Greenwood district. The community was destroyed, and estimates of the death toll vary, but it is believed that hundreds of African Americans were killed, with thousands left homeless.

The Tulsa Race Massacre was largely covered up and omitted from history books for many years, but in recent decades, efforts to acknowledge and remember this dark chapter in American history have increased. In 2021, the centennial of the massacre, there was a renewed focus on commemorating the victims and survivors, as well as examining the ongoing impact of the massacre on the descendants of those affected.
