Ethnic operations

During the 1930s, categorisation of so-called enemies of the people shifted from the usual Marxist–Leninist, class-based terms, such as kulak, to ethnic-based ones. The partial removal of potentially trouble-making ethnic groups was a technique used consistently by Joseph Stalin during his government; between 1935 and 1938 alone, at least ten different nationalities were deported. Germany's invasion of the Soviet Union led to a massive escalation in Soviet ethnic cleansing.

The Deportation of Koreans in the Soviet Union, originally conceived in 1926, initiated in 1930, and carried through in 1937, was the first mass transfer of an entire nationality in the Soviet Union. Almost the entire Soviet population of ethnic Koreans (171,781 people) were forcibly moved from the Russian Far East to unpopulated areas of the Kazakh SSR and the Uzbek SSR in October 1937.

Looking at the entire period of Stalin's rule, one can list: Poles (1939–1941 and 1944–1945), Kola Norwegians (1940–1942), Romanians (1941 and 1944–1953), Estonians, Latvians and Lithuanians (1941 and 1945–1949), Volga Germans (1941–1945), Ingrian Finns (1929–1931 and 1935–1939), Finnish people in Karelia (1940–1941, 1944), Crimean Tatars, Crimean Greeks (1944) and Caucasus Greeks (1949–50), Kalmyks, Balkars, Italians of Crimea, Karachays, Meskhetian Turks, Karapapaks, Far East Koreans (1937), Chechens and Ingushs (1944). Shortly before, during and immediately after World War II, Stalin conducted a series of deportations on a huge scale which profoundly affected the ethnic map of the Soviet Union. It is estimated that between 1941 and 1949 nearly 3.3 million were deported to Siberia and the Central Asian republics. By some estimates, up to 43% of the resettled population died of diseases and malnutrition.
