Soviet deportations from Latvia
In 1941 and 1945–1951, the Soviet government deported around 60,000 people from Latvia to inhospitable remote areas of the Soviet Union, which had occupied the country in 1940 and again in 1944/1945. Similar deportations were organized by the Soviet regime in the fellow occupied Baltic states of Estonia and Lithuania at the same time.
