The Tulsa race riots has been inscribed in world history as one of the worst and most violent demonstrations to ever take place.

On June 1, 1921, chaos erupted in the Greenwood district of downtown Tulsa, Oklahoma, a segregated area at the time which was widely known as the “Black Wall Street.” Anger ensued among the city’s white residents after rumors began to spread of an encounter a young black man, Dick Rowland, had with a white woman, Sarah Page, just two days prior. Details on the exact moments that led up to the riot vary, however, an archived article in The Chicago Tribune recounts one retelling:

On May 30, 1921, a 19-year-old black shoeshine man named Dick Rowland entered the Drexel building downtown to use the segregated restroom. While approaching the elevator, which apparently hadn’t stopped evenly with the floor, Rowland tripped and fell on the operator, a 17-year-old white girl named Sarah Page. The girl screamed, drawing the attention of onlookers who yelled “rape.”

Rowland was subsequently arrested the same day, and an egregious article in the town’s newspaper called for his lynching. This then led to an armed standoff at the courthouse between a white mob, that came to kill Rowland, and an outnumbered group of black residents, who arrived to help protect him but were eventually forced to retreat.

Chaos continued over the next 12 hours or so, according to reports, and flames engulfed many parts of the black-occupied areas of Greenwood. White rioters ransacked the town as they went on a shooting and looting rampage attacking its black residents. The violence later prompted the state’s governor to declare martial law and bring in the National Guard. The riot ceased within 24 hours and left the city in ruins. Initial reports say over 800 people were injured and around 35 people died, although a more recent investigation into the case by the Tulsa Race Riot Commission claims close to 300 people were killed.
