Soviet zone (1939–1941)
By the end of the Polish Defensive War the Soviet Union had taken over 52.1% of the territory of Poland (circa 200,000 km2), with over 13,700,000 people. The estimates vary; Professor Elżbieta Trela-Mazur gives the following numbers in regards to the ethnic composition of these areas: 38% Poles (ca. 5.1 million people), 37% Ukrainians, 14.5% Belarusians, 8.4% Jews, 0.9% Russians and 0.6% Germans. There were also 336,000 refugees from areas occupied by Germany, most of them Jews (198,000). [2] Areas occupied by the USSR were annexed to Soviet territory, with the exception of area of Wilno, which was transferred to Lithuania, although soon attached to USSR, when Lithuania became a Soviet republic.
Under the terms of the Molotov–Ribbentrop pact, adjusted by agreement on 28 September 1939, the Soviet Union, annexed all Polish territory east of the line of the rivers Pisa, Narew, Bug and San, except for the area around Wilno (Vilnius), which was given to Lithuania, and the Suwałki region, which was annexed by Germany. These territories were largely inhabited by Ukrainians and Belarusians, with minorities of Poles and Jews (see exact numbers in Curzon line). The total area, including the area given to Lithuania, was 201,000 square kilometres, with a population of 13.5 million. A small strip of land that was part of Hungary before 1914, was also given to Slovakia.
The history of Poland from 1939 to 1945 encompasses primarily the period from the invasion of Poland by Nazi Germany and the Soviet Union to the end of World War II. Following the German–Soviet non-aggression pact, Poland was invaded by Nazi Germany on 1 September 1939 and by the Soviet Union on 17 September. The campaigns ended in early October with Germany and the Soviet Union dividing and annexing the whole of Poland. After the Axis attack on the Soviet Union in the summer of 1941, the entirety of Poland was occupied by Germany, which proceeded to advance its racial and genocidal policies across Poland.
Seventeen days after the German invasion of Poland in 1939, which marked the beginning of the Second World War, the Soviet Union entered the eastern regions of Poland and annexed territories totalling 201,015 square kilometres (77,612 sq mi) with a population of 13,299,000. Inhabitants besides ethnic Poles included Belarusian and Ukrainian major population groups, and also Czechs, Lithuanians, Jews, and other minority groups.
The Reichskommissariat Ostland was established by Nazi Germany in 1941 during World War II. It became the civilian occupation regime in Lithuania, Latvia, Estonia, and the western part of Byelorussian SSR. German planning documents initially referred to an equivalent Reichskommissariat Baltenland. The political organization for this territory – after an initial period of military administration before its establishment – involved a German civilian administration, nominally under the authority of the Reich Ministry for the Occupied Eastern Territories led by Nazi ideologist Alfred Rosenberg, but actually controlled by the Nazi official Hinrich Lohse, its appointed Reichskommissar.
Eastern Borderlands or simply Borderlands was a term coined for the eastern part of the Second Polish Republic during the interwar period (1918–1939). Largely agricultural and extensively multi-ethnic with a Polish minority, it amounted to nearly half of the territory of interwar Poland. Historically situated in the eastern Polish–Lithuanian Commonwealth, following the 18th-century foreign partitions it was divided between the Empires of Russia and Austria-Hungary, and ceded to Poland in 1921 after the Treaty of Riga. As a result of the post-World War II border changes, all of the territory was ceded to the USSR, and none of it is in modern Poland.
Kobryn or Kobrin, is a town in Brest Region, Belarus. It serves as the administrative center of Kobryn District. It is located in the southwestern corner of Belarus, where the Mukhavets river and Dnieper–Bug Canal meet. The town lies about 52 kilometres (32 mi) east of the city of Brest. As of 2024, it has a population of 52,635.
The Reichskommissariat Ukraine was established by Nazi Germany in 1941 during World War II. It was the civilian occupation regime of much of Nazi German-occupied Ukraine. It was governed by the Reich Ministry for the Occupied Eastern Territories headed by Alfred Rosenberg. Between September 1941 and August 1944, the Reichskommissariat was administered by Erich Koch as the Reichskommissar. The administration's tasks included the pacification of the region and the exploitation, for German benefit, of its resources and people. Adolf Hitler issued a Führer decree defining the administration of the newly-occupied Eastern territories on 17 July 1941.
The Belarusian Central Council was a puppet administrative body in German-occupied Belarus during World War II. It was established by Nazi Germany within Reichskommissariat Ostland in 1943–44, following requests by collaborationist Belarusian politicians hoping to create a Belarusian state with German support.
Western Belorussia or Western Belarus is a historical region of modern-day Belarus which belonged to the Second Polish Republic during the interwar period. For twenty years before the 1939 invasion of Poland, it was the northern part of the Polish Kresy macroregion. Following the end of World War II in Europe, most of Western Belorussia was ceded to the Soviet Union by the Allies, while some of it, including Białystok, was given to the Polish People's Republic. Until the dissolution of the Soviet Union in 1991, Western Belorussia formed the western part of the Byelorussian Soviet Socialist Republic (BSSR). Today, it constitutes the west of modern Belarus.
When the Second World War in Europe began, the territory which now forms the country of Belarus was divided between the Soviet Union and the Second Polish Republic. The borders of Soviet Belarus were greatly expanded in the Soviet invasion of Poland of 1939. In 1941, the country was occupied by Nazi Germany. Following the German military disasters at Stalingrad and Kursk, the collaborationist Belarusian Central Council (BCC) was formed by the Germans in order to raise local support for their anti-Soviet operations. The BCC in turn formed the twenty-thousand strong Belarusian Home Defence (BKA), active from 23 February 1944 to 28 April 1945. Assistance to collaborators was offered by the local Soviet administrative governments, and prewar public organizations including the former Soviet Belarusian Youth. The country was soon retaken by the Red Army in 1944. Devastated by the war, Belarus lost significant populations and economic resources. Many battles occurred in Belarusian territory. Belarusians also participated in the advance towards Berlin.
The Belarusian minority in Poland is composed of 47,000 people according to the Polish census of 2011. This number decreased in the last decades from over 300,000 due to an active process of assimilation. Most of them live in the Podlaskie Voivodeship.
After the German invasion of the Soviet Union, the Baltic states were under military occupation by Nazi Germany from 1941 to 1944. Initially, many Estonians, Latvians, and Lithuanians considered the Germans liberators from the Soviet Union.
Bialystok District was an administrative unit of Nazi Germany created during the World War II invasion of the Soviet Union. It was to the south-east of East Prussia, in present-day northeastern Poland as well as in smaller sections of adjacent present-day Belarus and Lithuania. It was sometimes also referred to by the designation South East Prussia along with the Regierungsbezirk Zichenau, although in contrast to the latter, it was not incorporated into, but merely attached to East Prussia.
The Polish population transfers in 1944–1946 from the eastern half of prewar Poland, were the forced migrations of Poles toward the end and in the aftermath of World War II. These were the result of a Soviet Union policy that had been ratified by the main Allies of World War II. Similarly, the Soviet Union had enforced policies between 1939 and 1941 which targeted and expelled ethnic Poles residing in the Soviet zone of occupation following the Nazi-Soviet invasion of Poland. The second wave of expulsions resulted from the retaking of Poland from the Wehrmacht by the Red Army. The USSR took over territory for its western republics.
The Holocaust in Belarus refers to the systematic extermination of Jews living in the Byelorussian Soviet Socialist Republic during its occupation by Nazi Germany in World War II. It is estimated that roughly 800,000 Belarusian Jews were murdered during the Holocaust. However, other estimates place the number of Jews killed between 500,000 and 550,000.
Dzisna is a town in Miory District, Vitebsk Region, in northern Belarus. It is located on the left bank of the Daugava River, near the confluence of the Dysna. Dzisna is located 133 kilometres (83 mi) northwest of Vitebsk. In 2017, its population was 1,500. As of 2024, it has a population of 1,386.
The Border Agreement between Poland and the USSR of 16 August 1945 established the borders between the Union of Soviet Socialist Republics (USSR) and the Republic of Poland. It was signed by the Provisional Government of National Unity formed by the Polish communists. According to the treaty, Poland officially accepted the ceding its pre-war Eastern territory to the USSR (Kresy) which was decided earlier in Yalta already. Some of the territory along the Curzon line, established by Stalin during the course of the war, was returned to Poland. The treaty also recognised the division of the former German East Prussia and ultimately approved the finalised delimitation line between the Soviet Union and Poland: from the Baltic Sea, to the border tripoint with Czechoslovakia in the Carpathians. The agreement entered into force on 5 February 1946.
Elections to the People's Assemblies of Western Ukraine and Western Belorussia, which took place on October 22, 1939, were an attempt to legitimize the annexation of the Second Polish Republic's eastern territories by the Soviet Union following the September 17 Soviet invasion of Poland in accordance with the secret protocol of the Molotov–Ribbentrop Pact. Only one month after these lands were occupied by the Red Army, the Soviet secret police and military led by the Party officials staged the local elections in an atmosphere of state terror. The referendum was rigged. The ballot envelopes were numbered and often handed over already sealed. By design, the candidates were unknown to their constituencies which were brought to the voting stations by armed militias. The results were to become the official legitimization of the Soviet takeover of what is known today as the Western Belorussia and the Western Ukraine. Consequently, both Assemblies voted for incorporation of all formerly Polish voivodeships into the Soviet Union.
The occupation of Poland by Nazi Germany and the Soviet Union during World War II (1939–1945) began with the Invasion of Poland in September 1939, and it was formally concluded with the defeat of Germany by the Allies in May 1945. Throughout the entire course of the occupation, the territory of Poland was divided between Nazi Germany and the Soviet Union (USSR), both of which intended to eradicate Poland's culture and subjugate its people. In the summer-autumn of 1941, the lands which were annexed by the Soviets were overrun by Germany in the course of the initially successful German attack on the USSR. After a few years of fighting, the Red Army drove the German forces out of the USSR and crossed into Poland from the rest of Central and Eastern Europe.
Generalbezirk Weißruthenien was one of the four administrative subdivisions of Reichskommissariat Ostland, the 1941–1945 civilian occupation regime established by Nazi Germany for the administration of the three Baltic countries and the western part of the Byelorussian SSR.
