History of Germany
The total of German war dead was 8% to 10% out of a prewar population of 69,000,000, or between 5.5 million and 7 million people. This included 4.5 million in the military, and between 1 and 2 million civilians. There was chaos as 11 million foreign workers and POWs left, while 14 million displaced refugees from the east and soldiers returned home. During the Cold War, the West German government estimated a death toll of 2.2 million civilians due to the flight and expulsion of Germans and through forced labour in the Soviet Union. This figure remained unchallenged until the 1990s, when some historians put the death toll at 500,000–600,000 confirmed deaths. In 2006 the German government reaffirmed its position that 2.0–2.5 million deaths occurred.
At the Potsdam Conference, Germany was divided into four military occupation zones by the Allies and did not regain independence until 1949. The provinces east of the Oder and Neisse rivers (the Oder-Neisse line) were transferred to Poland, Lithuania, and Russia (Kaliningrad oblast); the 6.7 million Germans living in Poland and the 2.5 million in Czechoslovakia were forced to move west, although most had already left when the war ended.
