population transfer in the Soviet Union

From 1930 to 1952, the government of the Soviet Union, on the orders of Soviet leader Joseph Stalin and under the direction of the NKVD official Lavrentiy Beria, forcibly transferred populations of various groups. These actions may be classified into the following broad categories: deportations of "anti-Soviet" categories of population (often classified as "enemies of the people"), deportations of entire nationalities, labor force transfer, and organized migrations in opposite directions to fill ethnically cleansed territories. Dekulakization marked the first time that an entire class was deported, whereas the deportation of Soviet Koreans in 1937 marked the precedent of a specific ethnic deportation of an entire nationality.

In most cases, their destinations were underpopulated remote areas. This includes deportations to the Soviet Union of non-Soviet citizens from countries outside the USSR. It has been estimated that, in their entirety, internal forced migrations affected at least 6 million people. Of this total, 1.8 million kulaks were deported in 1930–31, 1.0 million peasants and ethnic minorities in 1932–1939, whereas about 3.5 million ethnic minorities were further resettled during 1940–52.
