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. 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.
