The former eastern territories of Germany are those provinces or regions east of the current eastern border of Germany (the Oder–Neisse line) which were lost by Germany after World War I and then World War II. The territories lost following World War I include most of the Province of Posen and West Prussia, and further territories lost after World War II include East Prussia, Farther Pomerania, East Brandenburg, Upper Silesia, and almost all of Lower Silesia. All territories lost in both World Wars account for 33% of the former German Empire, while land ceded by Germany after World War II constituted roughly 25% of its pre-war Weimar territory. In present-day Germany, the term usually refers only to the territories lost in World War II, while in Poland the territories acquired from Germany after World War II were dubbed the "Recovered Territories" by the Soviet-installed Polish government.
