It’s been called the single worst incident of racial violence in American history and it occurred 100 years ago this weekend. Between May 31–June 1, 1921, mobs of white residents attacked Black residents and businesses in the Greenwood District of Tulsa, Oklahoma, leaving as many as 35 square blocks of destruction.

Depending on the source, as many as 800 people were injured. Approximately 39 people were confirmed killed, however larger estimates have been reported over the years. 

The Rev. Dr. J. Herbert Nelson, II, Stated Clerk of the General Assembly of the Presbyterian Church (U.S.A.), looks back on that tragic Memorial Day weekend and provides perspective to present-day race struggles.
