No, I am not here writing about forced migration of indigenous Americans. I’ll address that later.
After World War II, the borders of Poland were significantly altered, resulting in population expulsions and migrations on a massive scale. The most notable changes occurred as a result of the Potsdam Conference in 1945, where the United States (Truman), the Soviet Union (Stalin0, and the United Kingdom (Atlee0 made decisions about post-war Europe, including the borders of Poland.
In the Protocol of the Proceedings, August 1, 1945: XIII. Orderly Transfers of German Populations. “…..The three Governments, having considered the question in all its aspects, recognize that the transfer to Germany of German populations or elements thereof, remaining in Poland, Czechoslovakia and Hungary, will have to be undertaken. They agree that any transfers that take place should be effected in an orderly and humane manner.”
Between 3.5 to 4.5 million Germans residing within the new borders of Poland were mandated to resettle in post-war Germany from 1946 to 1949. The expulsion and migration processes were part of a larger ethnic policy aimed at creating an ethnically homogeneous Polish state.
In all, upwards of 12 million German speaking persons were forced to relocate after WW2 from Poland and other Central and East European countries.
