Bierut Decrees German: Bierut-Dekrete is a term used in German historiography referring to a series of decrees, laws and regulations enacted by the Provisional Government of National Unity between 1945 and 1946 concerning the flight and expulsion of ethnic Germans from Poland and the property issues arising from them. The term presents a conscious echo of the Beneš decrees which have been seen by critics as providing a blue print for the ethnic cleansing of German and Hungarian minorities from Czechoslovakia between 1945 and 1948.
