Silesian Uprisings
The Silesian Uprisings (; ) 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 separatists, seeking to have the area transferred to the newly founded Polish Republic, fought German police and paramilitary forces, as the former sought to keep the area part of the new German state founded after World War I. Following the conflict, the area was divided between the two countries. The rebellions have subsequently been commemorated in modern Poland as an example of Polish nationalism.
