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 Polish minority in the Soviet Union are Polish diaspora who used to reside near or within the borders of the Soviet Union before its dissolution. Some of them continued to live in the post-Soviet states, most notably in Lithuania, Belarus, and Ukraine, the areas historically associated with the Polish–Lithuanian Commonwealth, as well as in Kazakhstan and Azerbaijan among others.
Around six million Polish citizens are estimated to have perished during World War II. Most were civilians killed by the actions of Nazi Germany, the Soviet Union, the Lithuanian Security Police, as well as the Organization of Ukrainian Nationalists and its offshoots.
Mass evacuation, forced displacement, expulsion, and deportation of millions of people took place across most countries involved in World War II. The Second World War caused the movement of the largest number of people in the shortest period of time in history. A number of these phenomena were categorised as violations of fundamental human values and norms by the Nuremberg Tribunal after the war ended. The mass movement of people – most of them refugees – had either been caused by the hostilities, or enforced by the former Axis and the Allied powers based on ideologies of race and ethnicity, culminating in the postwar border changes enacted by international settlements. The refugee crisis created across formerly occupied territories in World War II provided the context for much of the new international refugee and global human rights architecture existing today.
The Polish government-in-exile, officially known as the Government of the Republic of Poland in exile, was the government in exile of Poland formed in the aftermath of the Invasion of Poland of September 1939, and the subsequent occupation of Poland by Germany, the Soviet Union, and the Slovak Republic, which brought to an end the Second Polish Republic.
The Sikorski–Mayski agreement was a treaty between the Soviet Union and Poland that was signed in London on 30 July 1941. Its name is taken from its two most notable signatories: the prime minister of Poland, Władysław Sikorski, and the Soviet ambassador to the United Kingdom, Ivan Mayski.
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.
A sybirak is a person resettled to Siberia. Like its Russian counterpart sibiryák, the word can refer to any dweller of Siberia, but it more specifically refers to Poles imprisoned or exiled to Siberia or even to those sent to the Russian Arctic or to Kazakhstan in the 1940s.
Anders' Army was the informal yet common name of the Polish Armed Forces in the East in the 1941–42 period, in recognition of its commander Władysław Anders. The army was created in the Soviet Union but, in March 1942, based on an understanding between the British, Polish, and Soviets, it was evacuated from the Soviet Union and made its way through Iran to Palestine. There it passed under British command and provided the bulk of the units and troops of the Polish II Corps, which fought in the Italian Campaign. Anders' Army is notable for having been primarily composed of liberated POWs and for Wojtek, a bear who had honorary membership.
The Polish Armed Forces in the East, also called Polish Army in the USSR, were the Polish military forces established in the Soviet Union during World War II.
The Polish Institute and Sikorski Museum, known as Sikorski Institute, named after General Władysław Sikorski, is a leading London-based museum and archive for research into Poland during World War II and the Polish diaspora. It is a non-governmental organisation managed by scholars from the Polish community in the United Kingdom, housed at 20 Prince's Gate in West London, in a Grade II listed terrace on Kensington Road facing Hyde Park. It is incidentally part of the same Victorian development by Charles James Freake as the nearby Polish Hearth Club. Although the institute is closer to the commercial centres of Kensington, it is just within the City of Westminster. In 1988 it merged with the formerly independent Polish Underground Movement (1939–1945) Study Trust –.
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.
In the aftermath of the German and Soviet invasion of Poland, which took place in September 1939, the territory of Poland was divided between Nazi Germany and the Soviet Union. The Soviets had ceased to recognise the Polish state at the start of the invasion. Since 1939 German and Soviet officials coordinated their Poland-related policies and repressive actions. For nearly two years following the invasion, the two occupiers continued to discuss bilateral plans for dealing with the Polish resistance during Gestapo-NKVD Conferences until Germany's Operation Barbarossa against the Soviet Union, in June 1941.
Tadeusz Piotrowski or Thaddeus Piotrowski is a Polish-American sociologist and author. He is a professor of sociology in the Social Science Division of the University of New Hampshire at Manchester in Manchester, New Hampshire.
Following the Soviet invasion of Poland at the onset of World War II, in accordance with the Nazi–Soviet Pact against Poland, the Soviet Union acquired more than half of the territory of the Second Polish Republic or about 201,000 square kilometres (78,000 sq mi) inhabited by more than 13,200,000 people. Within months, in order to de-Polonize annexed lands, the Soviet NKVD rounded up and deported between 320,000 and 1 million Polish nationals to the eastern parts of the USSR, the Urals, and Siberia. There were four waves of deportations of entire families with children, women, and elderly people aboard freight trains from 1940 until 1941. The second wave of deportations by the Soviet occupational forces across the Kresy macroregion, affected 300,000 to 330,000 Poles, sent primarily to Kazakhstan.
Around 6 million Polish citizens perished during World War II: about one fifth of the entire pre-war population of Poland. Most of them were civilian victims of the war crimes and the crimes against humanity which Nazi Germany and the Soviet Union committed during their occupation of Poland. Approximately half of them were Polish Jews who were killed in The Holocaust. Statistics for Polish casualties during World War II are divergent and contradictory. This article provides a summary of the estimates of Poland's human losses in the war as well as a summary of the causes of them.
The flight and forced displacement of Poles from all territories east of the Second Polish Republic (Kresy) pertains to the dramatic decrease of Polish presence on the territory of the post-war Soviet Union in the first half of the 20th century. The greatest migrations took place in waves between the Bolshevik Revolution of 1917 and in the aftermath of World War II in Europe.
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.
The Basilian Church of St Peter and Paul and Monastery in Berezwecz was a historic sacred structure in what is today Hlybokaye, Belarus. The church and monastery began with a foundation in 1637 by Joseph Korsak, the voivode of Mścisław. Run by the Order of Saint Basil the Great, the church and monastery were rebuilt in 1750-67 according to a design by Johann Christoph Glaubitz. A widely admired example of Vilnian Baroque the structure's facade was constructed of nine convex and eight concave surfaces.
