Oder–Neisse line

The Oder–Neisse line is the international border between Germany and Poland. It was drawn at the Potsdam Conference in the aftermath of the Second World War and is primarily delineated along the Oder and Lusatian Neisse rivers in Central Europe, meeting the Baltic Sea to the north, just west of the Polish seaports of Szczecin and Świnoujście . All prewar German territory east of the line and within the 1937 German boundaries were placed under International Law Administrative status, with most of it being made part of newly-Communist Poland. The small remainder, consisting of the territory surrounding the German city of Königsberg in northern East Prussia, was allocated to the Soviet Union after the war . The vast majority of the native German population in these territories fled, or were killed or expelled by force. The Oder–Neisse line marked the border between the German Democratic Republic and Poland from 1950 to 1990. East Germany confirmed the border with Poland in 1950, while West Germany, after a period of refusal, finally accepted the border in 1970. In 1990 the newly reunified Germany and the Republic of Poland signed a treaty recognizing it as their border.
