Polish insurgents in 1921.
On this day in 1921, the Third Silesian Uprising commenced in which Poles in Upper Silesia who sought to separate from Germany. The uprising followed a plebiscite which yielded indefinite results and followed Polish fears that the British would support German claims to the region, which was proved to be correct. The French supported the Poles.
During the fighting, the French somewhat supported the Polish insurgents and the British somewhat supported German forces in the region, but outside forces were barred from entry. Ultimately the Poles prevailed.
On the same day the US announced that it would not mediate reparations disputes involving Germany and the Allies. The French mobilized 50,000 men for anticipated Ruhr occupation.
Also on that day President Harding was visited by the American Waldensian Aid Society.

While I'd never heard of it, it still exists, and is based in the Waldensian Church, a protestant church that claims a connection with the Waldensian heresy of the Middle Ages. In 1975 it merged with the Methodist Church.
Harding appears to have had a busy day of meetings.
He met with members of International Association of Printing House Craftsmen, depicted above.
And also with the Alabama Congressional delegation.
And with Social Service School Workers.
Somebody he didn't meet with, but who was photographed that day, was Prince Zerdecheno, who claimed the title of Emir of Kurdistan, and his wife, May 2, 1921.
Elsewhere the famous hairpin turn on the Mohawk Trail and the Niagara Falls Fire Department were photographed.
