In 1921, the Polish insurgents in eastern Upper Silesia issued their own stamps (Korfanty issue), which were not officially recognized, but were nevertheless accepted in postal service.

In late April 1921, rumours spread that the British position would prevail, prompting the local Polish activists to organise an uprising. The insurection started on 2–3 May 1921.

The French wanted to weaken Germany, and thus supported Polish claims on the territory; the British and the Italians disagreed, in part because the German government declared that a loss of the Silesian industries would render Germany incapable of paying the demanded war reparations.

The Third Silesian Uprising was the last, largest and longest of the three Silesian Uprisings. It began in the aftermath of a plebiscite that yielded mixed results. The British and French governments could not reach a consensus on the interpretation of the plebiscite.
