Repatriation after World War II

When the war ended in May 1945, thousands of Soviet citizens were forcefully repatriated (against their will) into the USSR. On 11 February 1945, at the conclusion of the Yalta Conference, the United States and United Kingdom signed a Repatriation Agreement with the USSR.

The interpretation of this Agreement resulted in the forcible repatriation of all Soviet citizens regardless of their wishes. Allied authorities ordered their military forces in Europe to deport to the Soviet Union millions of former residents of the USSR (some of whom collaborated with the Germans), including numerous people who had left Russia and established different citizenships for up to decades prior. The forced repatriation operations took place from 1945 to 1947.

At the end of World War II, more than 5 million " displaced people " from the Soviet Union survived in German captivity. About 3 million had been forced laborers (Ostarbeiter) in Germany and occupied territories.

Surviving POWs, about 1.5 million, repatriated Ostarbeiter, and other displaced people, totalling more than 4,000,000 people were sent to special NKVD filtration camps (not Gulag). By 1946, 80% civilians and 20% of PoWs were freed, 5% of civilians, and 43% of PoWs re-drafted, 10% of civilians and 22% of PoWs were sent to labor battalions, and 2% of civilians and 15% of the PoWs (226,127 out of 1,539,475 total) transferred to the NKVD, i.e. the Gulag.
