what happened to most eastern european countries after ww2
Flight and expulsion of Germans (1944–50) The Second World War ended in Europe with Germany's defeat in May 1945. By this time, all of Eastern and much of Central Europe was under Soviet occupation. This included most of the historical German settlement areas, as well as the Soviet occupation zone in eastern Germany.
Western Allied invasion of Germany The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II. The Allied invasion of Germany started with the Western Allies crossing the Rhine River in March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to Austria in the south before the Germans surrendered on 8 May 1945. This is known as the "Central Europe Campaign" in United States military histories.
