Silesian Uprisings
The Silesian Uprisings (Polish: Powstania śląskie; Silesian: Ślōnske aufsztandy; German: Aufstände in Oberschlesien, Polenaufstände) were a series of three uprisings from August 1919 to July 1921 in Upper Silesia, which was part of the Weimar Republic at the time. Ethnic Polish and Polish-Silesian insurrectionists, seeking to have the area transferred to the newly founded Polish Republic, fought German police and paramilitary forces, which sought to keep the area part of the new German state founded after World War I and the subsequent revolutions in Germany.
