On this day in labor history, the year was 1921.

That was the day one of the worst race riots in American history began in Tulsa, Oklahoma.

In a frenzy of anti-black violence, a white mob destroyed virtually the entire black neighborhood of Greenwood.

Over the course of two days, as many as 300, mostly black residents were killed. ‘Black Wall Street’ had been burned to the ground, leaving 10,000 homeless.

The day before, Dick Rowland, a young black man tripped as he boarded an elevator at his job.

He fell against the young white woman elevator operator.

When she shrieked, nearby department store employees assumed she had been assaulted.

Rowland was arrested and newspapers fanned the flames of race violence and vigilantism.

On this day, white racist mobs surrounded the Tulsa County Courthouse where Rowland was being held and demanded he be turned over to them.

Returning black veterans had become increasingly assertive about their rights as citizens.

They marched to the courthouse, armed in an attempt to prevent Rowland’s lynching.

When the vets refused to disarm in the face of demands by the white mob, gunfire ensued, touching off 16 hours of fighting that literally decimated the community black workers and professionals had built up over the course of decades.

The National Guard was called out, mainly to disarm and round up black residents of Greenwood. Witnesses reported that Greenwood was bombed from the air by police and by Sinclair Oil company planes.

The history of the riot was buried for more than half a century.

It would take until 1997 for the Oklahoma State Legislature to set up a commission to uncover the bloody details, produce a 200 plus page report and recommend millions in reparations.
