Estonia’s experience of the Second World War was shaped by successive Soviet and German occupations and by several overlapping forms of civilian displacement. The Molotov–Ribbentrop Pact of 23 August 1939 placed Estonia in the Soviet sphere of influence, leading to Soviet military bases, occupation in June 1940, incorporation into the Soviet Union, and mass repression. German forces occupied the country from 1941 to 1944 and imposed an administration within Reichskommissariat Ostland, directing the persecution and murder of Jews, Roma, Soviet prisoners of war, political opponents, and other targeted people. The Soviet return in 1944 coincided with a large refugee flight across the Baltic Sea and to German-held territory. These events dismantled the institutions of the interwar republic, transformed Estonia’s population, and preceded Soviet rule that continued until independence was restored in 1991.

Historical Background
Estonia had been an independent republic since 1918 when Nazi Germany and the Soviet Union signed the Molotov–Ribbentrop Pact on 23 August 1939. Its secret protocol assigned Estonia to the Soviet sphere of influence. Under pressure from Moscow, Estonia accepted the Soviet–Estonian Mutual Assistance Pact on 28 September 1939. Soviet forces entered during October and established bases on Estonian territory. The base system gave the Soviet Union a substantial military presence before the occupation of June 1940. Compulsory land acquisitions connected with the bases later became an issue in Estonian restitution policy.
The regional settlement also affected Estonia’s Baltic German population. Under the Nazi-sponsored Umsiedlung programme, 13,339 Germans left Estonia in 1939 and 1940; roughly 2,000 more departed after the Soviet takeover. Baltic Germans had long been present in Estonia’s towns, commercial life, landholding, administration, and cultural institutions. Their departure was organized under Nazi German resettlement policy rather than through a single Estonian measure, and it largely ended the presence of this established minority community in Estonia.
Chronology and Course
Soviet forces occupied Estonia on 17 June 1940. Andrei Zhdanov, a Soviet emissary, participated in the political takeover. A government headed by Johannes Vares was installed on 21 June, followed by elections on 14–15 July that took place under Soviet control and did not permit a free contest among political alternatives. On 6 August 1940, the Soviet Union formally incorporated Estonia as the Estonian Soviet Socialist Republic. The institutions of the interwar republic were replaced by Soviet political, legal, and administrative structures, while arrests, nationalization, and repression accompanied the process.
On 14 June 1941, Soviet security bodies deported more than 10,000 people from Estonia. One frequently cited count is 10,861, including more than 5,000 women and more than 2,500 children. Men were commonly separated from their families and sent to prison camps, while women and children were transported into internal exile, including to Siberian destinations. Those targeted included state officials, military officers, police personnel, farmers, business figures, and family members. The local operational headquarters coordinating the deportation included Boris Kumm, Andrei Murro, Aleksei Shkurin, Venyamin Gulst, and Rudolf James.
Germany invaded the Soviet Union on 22 June 1941. During the German advance through the Baltic region in July and August, Soviet authorities mobilized and forcibly transferred many Estonian men to the USSR. The Estonian International Commission estimated that 32,000 to 33,000 of approximately 50,000 men gathered in these operations were taken eastward. It also recorded the evacuation of about 25,000 residents. German forces occupied Estonia between July and October 1941, after which the territory was incorporated into the German civil administration of Reichskommissariat Ostland.
In 1944, Soviet advances again brought the front to Estonia. As German forces withdrew and Soviet forces approached, Prime Minister and acting president Jüri Uluots sought to preserve constitutional continuity. In September, he appointed Otto Tief to head a short-lived government in Tallinn. Its authority was overtaken by the military situation and the return of Soviet forces. Between August and early October 1944, an estimated 75,000 to 80,000 people fled Estonia for Sweden, Finland, Germany, and German-controlled territory. More than 40,000 reached Germany or German-held areas, while about 27,000 reached Sweden. Soviet forces re-established control during autumn 1944, and Soviet rule continued after the European war ended on 8 May 1945.
Actors and Institutions
The Soviet takeover of 1940 and repression during 1940–41 involved central Soviet authorities, the Communist Party of the Soviet Union, the Red Army, and state-security bodies including the NKVD and NKGB. Estonian SSR institutions replaced the former republican government and operated within all-Union party, security, and administrative structures. Tallinn’s Patarei prison was among the sites used for arrest and detention during the first Soviet occupation.
German authority rested with military forces, Reichskommissariat Ostland, and SS and police institutions. Einsatzgruppe A, led by Walter Stahlecker, and Einsatzkommando 1a, led by Martin Sandberger, were among the German units involved in persecution and mass murder in Estonia. German and Estonian police and auxiliary formations assisted in some operations. The Estonian International Commission found evidence concerning particular local units and individuals, while cautioning that membership in a named formation alone does not establish an individual’s participation in a crime. German occupation authorities, SS bodies, and police institutions directed the policies of persecution and murder.
Human Consequences
Displacement occurred through distinct policies and wartime developments rather than through one single operation. The Baltic German resettlement of 1939–40 removed most of that community from Estonia. The June 1941 Soviet deportation separated families and sent prisoners and exiles to distant parts of the USSR. Soviet mobilization and evacuation during the German advance removed thousands more residents. The refugee flight of 1944 dispersed Estonians across Sweden, Finland, Germany, and other destinations, creating communities abroad that continued through the Soviet period.
Under German occupation, nearly all Jews who remained in Estonia after the invasion were murdered by the end of 1941. German authorities also deported Jews from elsewhere in German-occupied Europe into Estonia. Roma, Soviet prisoners of war, political opponents, and other civilians were persecuted. The German-run Vaivara concentration-camp complex operated in northeastern Estonia’s oil-shale region from September 1943 to September 1944. As Soviet forces approached, prisoners were evacuated. Approximately 2,000 prisoners were murdered at Klooga in September 1944.
Estonia’s Foreign Ministry has estimated that 70,000 to 75,000 Estonians died between 1940 and 1945 as a result of occupation and war. That estimate does not encompass the full demographic effects of flight, forced transfer, imprisonment, family separation, and the dispersal of established communities. Individual records of the 1944 refugee flight remain incomplete, so the overall number of refugees is expressed as an estimate rather than a settled count.
Historical Significance
The occupations altered Estonia’s state institutions and population structure. The Soviet occupation of 1940 ended the functioning of the interwar republic and installed Soviet political, legal, and economic arrangements. After 1944, local self-government bodies were dissolved or subordinated to Soviet administration. Nationalization was followed by postwar collectivization. State-directed industrial development expanded oil-shale extraction in northeastern Estonia, while labor and construction battalions were used in reconstruction and the militarization of parts of the country.
The demographic consequences were uneven across communities. The Baltic German population had largely departed by 1940. Jewish communal life in Estonia was devastated under German occupation, while Roma were also targeted. The 1944 flight established enduring Estonian communities in Sweden, Germany, North America, the United Kingdom, Australia, and elsewhere. These refugee networks maintained cultural, religious, educational, and political institutions outside Estonia during the later Soviet period, alongside Estonian diplomatic representation that remained in Western countries.
Memory and Debate
Estonian official institutions and the Estonian International Commission describe the 1940 incorporation as occupation and annexation. Soviet-era official accounts characterized Estonia’s entry into the USSR as voluntary. Estonia’s post-1991 legal framework and the commission’s findings reject that account, citing the Soviet military presence, political coercion, controlled elections, and dismantling of independent institutions.
Public historical memory includes Soviet deportation, German persecution and mass murder, wartime mobilization, resistance, collaboration, and refugee flight. These experiences involved different authorities, policies, and affected communities rather than a single shared experience. The destruction of Jewish communal life, the departure of Baltic Germans, family separations caused by deportation and flight, and the continuation of Estonian institutions abroad remain central elements in Estonia’s record of the war and the subsequent Soviet period.
