On May 30, 1921, Dick Rowland, a Black teenage shoe shiner from Greenwood, was arrested for allegedly assaulting a white woman named Sarah Page. Courts later deemed Rowland not guilty. He either tripped in the elevator or bumped into Page, whose scream prompted the white store clerk to report the incident as “assault.”
The Tulsa Tribune printed an article calling for the lynching of Dick Rowland while he was being held in a cell where the sheriff had previously allowed a lynch mob to kidnap another Black man. Upon hearing the news, a group of Black WW1 veterans from Greenwood, came armed to protect Rowland from the steadily growing lynch mob outside the jail. the sheriff turned them away but the group of 75 men later returned when the lynch mob had swelled to over 2,000. The first shots were fired when a member of the mob attempted to forcibly disarm a Black veteran.
The next day, a mob of white men and boys, many deputized by the police, alongside members of the national guard, rushed into Greenwood, shooting Black people on sight and looting and burning homes and businesses. As many as 13 planes flew overhead, dropping bombs and shooting from the sky.
The mob destroyed 35 square blocks -- 1,200 homes, 60 businesses, a school, a hospital, a library, and a dozen churches burned to the ground. Over 800 people were admitted to the hospital. While the mob stopped firefighters from fighting the flames, the National Guard arrested fleeing Black people. There were reports of white women bringing their children to watch Black residents forced to flee their homes.
In the aftermath, the KKK used the massacre as a recruiting tool, sending postcards of the massacre all over the country. In the months following the massacre, Tulsa's KKK grew to be one of the largest chapters in the USA.
