Flight and expulsion of Germans

The wartime flight and postwar forced displacement of ethnic German populations from Central and Eastern Europe, chiefly between 1944 and 1950. It involved fleeing the advancing Soviet armies, expulsions authorized by the Allies, and population transfers organized by postwar governments.

Red Army: The Soviet Union’s principal land force during the Second World War. Its advance into German-occupied Europe drove the first large-scale westward flight.
Second World War: A global war fought from 1939 to 1945, centered on the conflict between the Axis powers and the Allies. German occupation and defeat transformed borders and triggered the displacement.
Winston Churchill: British prime minister during most of the Second World War and again from 1951 to 1955. He supported transferring Poland westward and discussed the removal of German populations.
Postwar border changes in Europe: The territorial adjustments made across Europe after the Second World War. New borders placed millions of German residents outside the postwar German state.
Flight and expulsion of Germans from Czechoslovakia: The wartime flight and postwar expulsion of ethnic Germans from Czechoslovakia, especially from 1944 to 1947. This national episode shows how local expulsions differed within the broader displacement.
Potsdam Agreement: The 1945 agreement among the United States, United Kingdom, and Soviet Union on postwar arrangements in Europe. It called for the transfer of German populations to Germany in an orderly and humane manner.
German occupation of Poland: Nazi Germany’s military occupation of Poland from 1939 to 1945, marked by terror, exploitation, and mass murder. German occupation and settlement policies shaped both wartime flight and postwar decisions about German communities.
Joseph Stalin: The leader of the Soviet Union from the late 1920s until his death in 1953. His government advanced the Soviet Union’s western border and backed Poland’s territorial shift.
Territorial changes of Poland after World War II: Poland’s postwar westward shift, which transferred its eastern territories to the Soviet Union and former German lands to Polish administration. The shift displaced German residents while millions of Poles moved from territories annexed by the Soviet Union.
Population exchange between Greece and Turkey: The compulsory exchange of Greek Orthodox and Muslim populations agreed by Greece and Turkey in 1923. Unlike the postwar German expulsions, it was formally organized through a bilateral convention.
