Ostarbeiters, "Osty"
"Ostarbeiter" (German: Ostarbeiter - worker from the East) is a term adopted in the Third Reich to designate people taken from Eastern Europe for the purpose of using them as free or low-paid labor (1942-1944). German officials (including the direct author of the term, Hermann Goering) used this term to designate "forced laborers from the East" who were originally from the territories of Eastern Europe that became Soviet after September 17, 1939, in accordance with the order of the government of the USSR of September 17, 1939, according to which the territories of Western Belarus and Western Ukraine were annexed to the Soviet Union by military means.
There is another semantic understanding and use of this term: the Soviet authorities and society used this term to designate all citizens deported by the German authorities to the territory of the Reich for the purpose of using them as labor.
