Greenwood is a historic freedom colony in Tulsa, Oklahoma. As one of the most prominent concentrations of African-American businesses in the United States during the early 20th century, it was popularly known as America's "Black Wall Street". It was burned to the ground in the Tulsa race massacre of 1921, in which a local white mob gathered and attacked the area. Between 75 and 300 Americans were killed, hundreds more were injured, and the homes of 5000 were destroyed, leaving them homeless. The massacre was one of the largest in the history of U.S. race relations, destroying the once-thriving Greenwood community. Within ten years of the massacre, surviving residents who chose to remain in Tulsa rebuilt much of the district. They accomplished this despite the opposition of many white Tulsa political and business leaders and punitive rezoning laws enacted to prevent reconstruction. It continued as a vital black community until segregation was overturned by the federal government during the 1950s and 1960s. Desegregation encouraged black citizens to live and shop elsewhere in the city, causing Greenwood to lose much of its original vitality. Since then, city leaders have attempted to encourage other economic development activity nearby. History Roots Many African Americans came to Oklahoma during the Native American removal.

This proved problematic as rules concerning the freedom of African Americans differed between tribes. Others later traveled to Oklahoma for the land rushes in 1889 through 1891 and continued in the years leading to 1907, the year Oklahoma became a state, hoping that a majority-black population could build a firewall against further extension of the system of racial degradation and segregation known as Jim Crow. Oklahoma represented the hope of change and provided a chance for African Americans to not only leave the lands of slavery but oppose the harsh racism of their previous homes. They travelled to Oklahoma by wagons, horses, trains, and even on foot. Many of the settlers were relatives of Native Americans who had traveled on foot with the Five Civilized Tribes along the Trail of Tears. Others were the descendants of people who had fled to Indian Territory. Many Black residents were also from the various Muskogee-speaking peoples, such as Creeks and Seminoles, while some had been
