Subdivisions of Polish territories during World War II
Subdivision of Polish territories during World War II can be divided into several phases, when territories of the Second Polish Republic were administered first by Nazi Germany and Soviet Union, then in their entirety by Nazi Germany and finally by the Soviet Union again. Starting with the reform of 1946, the administrative division was returned to Poland. After Germany and the Soviet Union had partitioned Poland in 1939, following their invasion, most of the ethnically Polish territory ended up under German control while the areas annexed by the Soviet union was ethnically diverse peoples with the territory being divided into several areas some of which had a significant non-Polish majority, many of whom felt alienated in the interwar Poland and welcomed the Soviets. Nonetheless Poles composed the largest single ethnic group on the territories annexed by the Soviets.
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, 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, 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. 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, 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. 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.
German zone (1939–1945)
Annexation of selected Polish territories
Under the terms of two decrees by Hitler, large areas of western Poland were annexed to Germany. These included all the territories taken by Prussia in Partitions of Poland which Germany subsequently lost under the 1918 Treaty of Versailles, including the Polish Corridor, Wielkopolska, as well as territories divided after plebiscites such as Upper Silesia, as well as a large area east of these territories, including the city of Łódź. The area of these annexed territories was 94,000 square kilometres and the population was about 10 million, the great majority of whom were Poles. The annexed parts were controlled by a German administration ruled by a Gauleiter, a system similar in practice to that of the Reich itself. Nearly 1 million Poles were expelled from this German ruled area, while 600,000 Germans from eastern Europe and 400,000 from the German Reich were settled there.
The remaining block of territory was placed under a German administration called the General Government, with its capital at Kraków. The General Government was subdivided into four districts, Warsaw, Lublin, Radom, and Kraków. A German lawyer and prominent Nazi, Hans Frank, was appointed "Governor-General of the occupied Polish territories" on 26 October 1939. Frank oversaw the segregation of the Jews into Nazi ghettos in the larger cities, particularly Warsaw, and the use of Polish civilians as forced and slave labour in German war industries.
East Galicia, which was incorporated into the General-Government and became its fifth district, the Galician District.
Return of Soviet administration (1944–1945)
Soviet forces returned to former territories of the Second Polish Republic during the 1944 summer offensive, Operation Bagration, specifically in the Lublin–Brest Offensive), leading to Vistula–Oder Offensive of 1945. However, in terms of international politics, a far more important victory was won by Joseph Stalin already in 1943, when the Western Allies yielded to his demands during the Tehran Conference, for the annexation of eastern Poland by the Soviet Union. With full Soviet control and sponsorship, in July 1944, the Polish Committee of National Liberation, a Polish provisional government was formed. Its purpose was to administer the territories earmarked for the return to the newly reformed Poland. Starting with the communist decrees of 1946, the legal powers were passed on to local administration.
Throughout World War II, Poland had a unique underground administration maintained by the Polish Underground State. For regional divisions of Poland by the underground army known as Armia Krajowa, see areas and regions of operation. Following the German surrender, Soviet agencies such as NKVD and SMERSH proceeded to eliminate all structures originating from the prewar Second Polish Republic. Over 20,000 Poles, including the hero of Auschwitz, Witold Pilecki, were murdered in communist prisons.
