The territories lost by Germany following World War I included areas with predominantly ethnically Polish population, especially the Province of Posen (Greater Poland and Kuyavia), most of the province of West Prussia (see the Polish Corridor), and East Upper Silesia reintegrated with Poland,[1] following the country's independence, as well as the Lithuanian-populated Klaipėda Region, which became part of Lithuania. Further territories lost after World War II include East Prussia, Farther Pomerania, Neumark, West Upper Silesia, and almost all of Lower Silesia (except for a small area east of and around Hoyerswerda).
