Where is East Prussia and all that has changed the map of Poland from 1938?
Before the First World War, there had no country of Poland. East Prussia was the area of land extending eastward along the Baltic coast from Stettin to Danzig and Königsberg. Russia controlled much of what is now Poland. As part of the Armistice of the First World War, Poland has been created (or recreated, if you want). The region of East Prussia remained Konigsberg through Germany, but the Poles have received a corridor along the river, including Danzig, East Prussia actually separating Germany.
