Soviet deportations from Estonia were a series of mass deportations by the Soviet Union from Estonia in 1941 and 1945–1951. The two largest waves of deportations occurred in June 1941 and March 1949 simultaneously in all three Baltic states (Estonia, Latvia, and Lithuania). The deportations targeted the various anti-Soviet dissidents: nationalists (i.e. political elite, military officers, policemen of independent Estonia), Forest Brothers, kulaks, and others. There were deportations based on ethnicity (Germans in 1945 and Ingrian Finns in 1947–1950) and religion (Jehovah's Witnesses in 1951). Estonians residing in the Leningrad Oblast had already been subjected to deportation since 1935.
