Expulsion of Germans from Poland after World War II

The flight and expulsion of Germans from Poland was the largest of a series of flights and expulsions of Germans in Europe during and after World War II. The German population fled or was expelled from all regions which are currently within the territorial boundaries of Poland, including the former eastern territories of Germany and parts of pre-war Poland.

During World War II, expulsions were initiated by Nazi Germany in occupied Poland. The Germans deported 2.478 million Polish citizens from the Polish areas annexed by Nazi Germany,murdered another 5.38–5.58 million Polish Jews and ethnic Poles, and resettled 1.3 million ethnic Germans in their place. Around 500,000 Germans were stationed in Poland as part of its occupation force; these consisted of people such as clerks, technicians and support staff.

The German population east of Oder-Neisse was estimated at over 11 million in early 1945. The first mass flight of Germans followed the Red Army's advance and was composed of both spontaneous flight driven by rumours of Soviet atrocities, and organised evacuation starting in the summer of 1944 and continuing through to the spring of 1945. Overall about 1% (100,000) of the German civilian population east of the Oder–Neisse line perished in the fighting prior to the surrender in May 1945. In 1945, the eastern territories of Germany as well as Polish areas annexed by Germany were occupied by the Soviet Red Army and Polish Communist military forces. German civilians were also sent as "reparations labor" to the USSR. The Soviet Union transferred former German territories in the east of the Oder–Neisse line to Poland in July 1945. In mid-1945, 4.5 to 4.6 million Germans remained on the territories under Polish control. Early expulsions in Poland were undertaken by the Polish Communist military authorities even before the Potsdam Conference ("wild expulsions"), to ensure the later integration into an ethnically homogeneous Poland as envisioned by the Polish Communists. Between seven hundred and eight hundred thousand Germans were affected. By early 1946, 932,000 had been verified as having Polish nationality. In the February 1946 census, 2,288,000 persons were listed as Germans and 417,400 became subject to verification aiming at the establishment of nationality.From the spring of 1946 the expulsions gradually became better organised, affecting the remaining German population. By 1950, 3,155,000 German civilians had been expelled and 1,043,550 were naturalised as Polish citizens. Germans considered "indispensable" for the Polish economy were retained; virtually all had left by 1960. Some 200,000 Germans in Poland were employed as forced labor in communist-administered camps prior to being expelled from Poland. Besides large camps, some of which were re-used German concentration camps, numerous other forced labour, punitive and internment camps, urban ghettos, and detention centres sometimes consisting only of a small cellar were set up.
