In turn, postwar Poland was assigned considerably smaller territories to the west including the prewar Free City of Danzig and the former territory of Germany east of the Oder–Neisse line, consisting of the southern portion of East Prussia and most of Pomerania, Neumark (East Brandenburg), and German Silesia. The German population fled or was forcibly expelled before these Recovered Territories (official term) were repopulated with Poles expelled from the eastern regions and those from central Poland. The small area of Zaolzie, which had been annexed by Poland in late 1938, was returned to Czechoslovakia on Stalin's orders.
