The Tulsa race massacre, also known as the Tulsa race riot or the Black Wall Street massacre, was a two-day-long white supremacist terrorist massacre that took place between May 31 and June 1, 1921, in Tulsa, Oklahoma. Mobs of white residents, some of whom had been appointed as deputies and armed by city government officials, attacked black residents and destroyed homes and businesses of the Greenwood District. The Greenwood district was a prosperous Black neighborhood in Tulsa, known as Black Wall Street, that was built by Black people for Black people. The massacre killed hundreds of residents, burned more than 1,250 homes, and erased years of Black success. The Tulsa Massacre claimed an estimated 150–300 lives, and over 800 people were seriously injured. The strained relationship between the white and black communities, the heightened jealousy of the success of the Black Wall Street area, and an incident involving a white elevator operator and a black man led to the Tulsa Race Riot. Armed white men looted, burned, and destroyed the black community. Schools in Oklahoma have been required to teach students about the massacre since 2002, and in 2020, the massacre officially became a part of the Oklahoma school curriculum. In 1996, 75 years after the massacre, a bipartisan group in the state legislature authorized the formation of the Oklahoma Commission to Study the Tulsa Race Riot of 1921. The commissions final report, published in 2001, states that the city had conspired with the racist mob, and it recommended a program of reparations to survivors and their descendants. The state passed legislation to establish scholarships for the descendants of survivors, encourage the economic development of Greenwood, and develop a park in memory of the victims of the massacre in Tulsa. The park was dedicated in 2010.
