The three Silesian Uprisings between 1919 and 1921 were armed Polish insurrections against German administration in Upper Silesia following the First World War, culminating in the third and most significant uprising in May 1921 — launched just weeks after a League of Nations plebiscite in which 59% of voters chose to remain with Germany. Despite losing the vote, the uprising ultimately succeeded in pressuring the League into partitioning the region, with the industrially critical eastern strip awarded to Poland in October 1921. The 2011 issue marks the 90th anniversary of that outcome.
