Latvia
Soviet era (1940–1941, 1944–1991)

In 1944, when Soviet military advances reached Latvia, heavy fighting took place in Latvia between German and Soviet troops, which ended in another German defeat. In the course of the war, both occupying forces conscripted Latvians into their armies, in this way increasing the loss of the nation's "live resources". In 1944, part of the Latvian territory once more came under Soviet control. The Soviets immediately began to reinstate the Soviet system. After the German surrender, it became clear that Soviet forces were there to stay, and Latvian national partisans, soon joined by some who had collaborated with the Germans, began to fight against the new occupier.

Anywhere from 120,000 to as many as 300,000 Latvians took refuge from the Soviet army by fleeing to Germany and Sweden. Most sources count 200,000 to 250,000 refugees leaving Latvia, with perhaps as many as 80,000 to 100,000 of them recaptured by the Soviets or, during few months immediately after the end of war, returned by the West. The Soviets reoccupied the country in 1944–1945, and further deportations followed as the country was collectivised and Sovietised.

On 25 March 1949, 43,000 rural residents (" kulaks ") and Latvian nationalists were deported to Siberia in a sweeping Operation Priboi in all three Baltic states, which was carefully planned and approved in Moscow already on 29 January 1949. This operation had the desired effect of reducing the anti-Soviet partisan activity. Between 136,000 and 190,000 Latvians, depending on the sources, were imprisoned or deported to Soviet concentration camps (the Gulag) in the post-war years from 1945 to 1952.

In the post-war period, Latvia was made to adopt Soviet farming methods. Rural areas were forced into collectivization. An extensive program to impose bilingualism was initiated in Latvia, limiting the use of Latvian language in official uses in favor of using Russian as the main language. All of the minority schools (Jewish, Polish, Belarusian, Estonian, Lithuanian) were closed down leaving only two media of instructions in the schools: Latvian and Russian. An influx of new colonists, including laborers, administrators, military personnel and their dependents from Russia and other Soviet republics started. By 1959 about 400,000 Russian settlers arrived and the ethnic Latvian population had fallen to 62%.

Since Latvia had maintained a well-developed infrastructure and educated specialists, Moscow decided to base some of the Soviet Union's most advanced manufacturing in Latvia. New industry was created in Latvia, including a major machinery factory RAF in Jelgava, electrotechnical factories in Riga, chemical factories in Daugavpils, Valmiera and Olaine —and some food and oil processing plants. Latvia manufactured trains, ships, minibuses, mopeds, telephones, radios and hi-fi systems, electrical and diesel engines, textiles, furniture, clothing, bags and luggage, shoes, musical instruments, home appliances, watches, tools and equipment, aviation and agricultural equipment and long list of other goods. Latvia had its own film industry and musical records factory (LPs). However, there were not enough people to operate the newly built factories. To maintain and expand industrial production, skilled workers were migrating from all over the Soviet Union, decreasing the proportion of ethnic Latvians in the republic. The population of Latvia reached its peak in 1990 at just under 2.7 million people.

In late 2018 the National Archives of Latvia released a full alphabetical index of some 10,000 people recruited as agents or informants by the Soviet KGB. 'The publication, which followed two decades of public debate and the passage of a special law, revealed the names, code names, birthplaces and other data on active and former KGB agents as of 1991, the year Latvia regained its independence from the Soviet Union.'
