As soon as the second World War ended, the allies forced displaced persons and refuges from all nationalities across liberated Europe to return “home.” This was, more often than not, against their will. “Home,” at that time, meant the USSR for more than 2,200,000 people. Of which, it is estimated, one on five ended up either shot or sent to a Gulag. Nobody cared.
These forced repatriations didn’t cease till 1947 as the Cold War became a thing.
It is said that the 50,000 Czech nationals still in Austria and Germany by 1948 during Communist coup in Prague were immediately accorded the status of political refugee at once as of February that year.
