The 1921 Tulsa Race Massacre in North Tulsa occurred less than a generation after the cessation of the tribal governments with Oklahoma statehood in 1907. It is likely that the Freedmen and their families of the Cherokee, Choctaw, Chickasaw, and Muscogee Nations would have been the majority of those impacted. The area impacted was located in the previous Cherokee and Muscogee Nations. Looking at the 1920 U. S. Census for the Greenwood District and without doing a detailed analysis, it appears that only about ten to fifteen percent of the residents were in this category.
