Territorial evolution of Poland in the 20th century |
---|
At the end of World War II, Poland underwent major changes to the location of its international border. In 1945, after the defeat of Nazi Germany, the Oder–Neisse line became its western border, [1] resulting in gaining the Recovered Territories from Germany. The Curzon Line became its eastern border, resulting in the loss of the Eastern Borderlands to the Soviet Union. [2]
These decisions were in accordance with the decisions made first by the Allies at the Tehran Conference of 1943 where the Soviet Union demanded the recognition of the line proposed by British Foreign Secretary Lord Curzon in 1920. [3]
The same Soviet stance was repeated by Joseph Stalin again at the Yalta Conference with Franklin D. Roosevelt and Winston Churchill in February 1945, but much more forcefully in the face of the looming German defeat. [4] The new borders were ratified at the Potsdam Conference of August 1945 exactly as proposed by Stalin who already controlled the whole of East-Central Europe. [4] Harry Truman remembered:
I remember at Potsdam, we got to discussing a matter in eastern Poland, and it was remarked by the Prime Minister of Great Britain that the Pope would not be happy over the arrangement of that Catholic end of Poland. And the Generalissimo, the Prime Minister of Russia leaned on the table, and he pulled his mustache like that, and looked over to Mr. Churchill and said: Mr. Churchill, Mr. Prime Minister, how many divisions did you say the Pope had? [5]
Large territories of Polish Second Republic were ceded to the Soviet Union by the Moscow-backed Polish government, and today form part of Lithuania, Belarus and Ukraine. Poland was instead given the Free State of Danzig and the German areas east of the rivers Oder and Neisse (see Recovered Territories), pending a final peace conference with Germany. Since a peace conference never took place, the lands were effectively ceded by Germany. [6] [ need quotation to verify ]
The population transfer of both Polish and Germans 1945–46 included many millions of people. [7] [8] The Polish territory in 1919–39 covered an area of 386,418 square kilometres (149,197 square miles). [9] But from 1947, Poland's territory was reduced to 312,679 square kilometres (120,726 square miles), so the country lost 73,739 square kilometres (28,471 square miles) of land. This difference amounts almost to the size of the Czech Republic, although Poland ended up with a much longer coastline on the Baltic Sea compared to its 1939 borders. In addition, the infrastructure in the former eastern territories of Germany was more developed than in the territories ceded to the Soviet Union.[ citation needed ]
The prewar eastern Polish territories of Kresy, which the Red Army had overrun during the Nazi-Soviet invasion of Poland in 1939 (excluding the Białystok region) were permanently ceded to the USSR by the new Polish communist government, and most of their Polish inhabitants expelled. As a result of the Potsdam Agreement to which Poland's government-in-exile was not invited, Poland lost 179,000 square kilometres (69,000 square miles) (45%) of prewar territories in the east, including over 12 million citizens of whom 4.3 million were Polish-speakers. Today, these territories are part of sovereign Belarus, Ukraine, and Lithuania. [10]
In turn, postwar Poland was assigned considerably smaller territories to the west including the prewar Free City of Danzig and the former territory of Germany east of the Oder–Neisse line, consisting of the southern portion of East Prussia and most of Pomerania, Neumark (East Brandenburg), and German Silesia. Poland also received the town of Swinemünde (now Świnoujście) on the island of Usedom and the city of Stettin (now Szczecin) on the western bank of the Oder river in accordance with the Potsdam Agreement. Therefore, these transferred territories did not then form part of the Soviet occupation zone of Germany or the subsequent state of East Germany.[ citation needed ]
The German population who had stayed at or had returned to their homes were forcibly expelled before these Recovered Territories (official term) were repopulated by Poles expelled from the eastern regions and those from central Poland. The borders of Poland resembled the borders of the German-Russian gains in World War 2, with the exception of the city of Bialystok. This is called the Curzon line. The small area of Trans-Olza, which had been annexed by Poland in late 1938, was returned to Czechoslovakia on Stalin's orders.[ citation needed ]
The Potsdam Conference was held at Potsdam in the Soviet occupation zone from July 17 to August 2, 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, Prime Ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war.
The Potsdam Agreement was the agreement among three of the Allies of World War II: the United Kingdom, the United States, and the Soviet Union after the war ended in Europe that was signed on 1 August 1945 and it was published the next day. A product of the Potsdam Conference, it concerned the military occupation and reconstruction of Germany, its border, and the entire European Theatre of War territory. It also addressed Germany's demilitarisation, reparations, the prosecution of war criminals and the mass expulsion of ethnic Germans from various parts of Europe. France was not invited to the conference but formally remained one of the powers occupying Germany.
During the later stages of World War II and the post-war period, Germans and Volksdeutsche fled and were expelled from various Eastern and Central European countries, including Czechoslovakia, and from the former German provinces of Lower and Upper Silesia, East Prussia, and the eastern parts of Brandenburg (Neumark) and Pomerania (Hinterpommern), which were annexed by Poland and the Soviet Union.
The Tehran Conference was a strategy meeting of the Allies of World War II, held between Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill from 28 November to 1 December 1943. It was the first of the Allied World War II conferences involving the "Big Three" and took place at the Soviet embassy in Tehran just over a year after the Anglo-Soviet invasion of Iran. The meeting occurred shortly after the Cairo Conference was held in Egypt for a discussion between the United States, the United Kingdom, and China from 22 to 26 November 1943. The Big Three would not meet again until 1945, when the Yalta Conference was held in Crimea from 4 to 11 February and the Potsdam Conference was held in Allied-occupied Germany from 17 July to August 2.
The Yalta Conference, held 4–11 February 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union to discuss the postwar reorganization of Germany and Europe. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin. The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov palaces.
The Curzon Line was a proposed demarcation line between the Second Polish Republic and the Soviet Union, two new states emerging after World War I. Based on a suggestion by Herbert James Paton, it was first proposed in 1919 by Lord Curzon, the British Foreign Secretary, to the Supreme War Council as a diplomatic basis for a future border agreement.
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.
In present-day Germany, the former eastern territories of Germany refer to those territories east of the current eastern border of Germany, i.e. the Oder–Neisse line, which historically had been considered German and which were annexed by Poland and the Soviet Union after World War II. In contrast to the lands awarded to the restored Polish state by the Treaty of Versailles after World War I, the German territories lost with the post-World War II Potsdam Agreement were either almost exclusively inhabited by Germans before 1945, mixed German–Polish with a German majority, or mixed German–Czech with a German majority (Glatz). Virtually the entire German population of the territories that did not flee voluntarily in the face of the Red Army advance of 1945, was violently expelled to Germany, with their possessions being forcibly expropriated.
Western betrayal is the view that the United Kingdom, France and the United States failed to meet their legal, diplomatic, military and moral obligations to the Czechoslovakians and Poles before, during and after World War II. It also sometimes refers to the treatment of other Central and Eastern European states by those three nations.
The Soviet occupation zone in Germany was an area of Germany that was occupied by the Soviet Union as a communist area, established as a result of the Potsdam Agreement on 2 August 1945. On 7 October 1949 the German Democratic Republic (GDR), commonly referred to in English as East Germany, was established in the Soviet occupation zone.
The Treaty of Warsaw was a treaty between the Federal Republic of Germany and the People's Republic of Poland. It was signed by Chancellor Willy Brandt and Prime Minister Józef Cyrankiewicz at the Presidential Palace on 7 December 1970, and it was ratified by the West German Bundestag on 17 May 1972.
The registered German minority in Poland is a group of German people that inhabit Poland, being the largest minority of the country. As of 2021, it had the population of 144,177.
"Restatement of Policy on Germany", or the "Speech of Hope", is a speech given by James F. Byrnes, the US Secretary of State, in Stuttgart on September 6, 1946.
The territorial evolution of Germany in this article include all changes in the modern territory of Germany from its unification making it a country on 1 January 1871 to the present although the history of "Germany" as a territorial polity concept and the history of the ethnic Germans are much longer and much more complex. Modern Germany was formed when the Kingdom of Prussia unified most of the German states, with the exception of multi-ethnic Austria, into the German Empire. After the First World War, on 10 January 1920, Germany lost about 13% of its territory to its neighbours, and the Weimar Republic was formed two days before this war was over. This republic included territories to the east of today's German borders.
The flight and expulsion of Germans from Poland was the largest of a series of flights and expulsions of Germans in Europe during and after World War II. The German population fled or was expelled from all regions which are currently within the territorial boundaries of Poland: including the former eastern territories of Germany annexed by Poland after the war and parts of pre-war Poland; despite acquiring territories from Germany, the Poles themselves were also expelled from the former eastern territories of Poland annexed by the Soviet Union. West German government figures of those evacuated, migrated, or expelled by 1950 totaled 8,030,000. Research by the West German government put the figure of Germans emigrating from Poland from 1951 to 1982 at 894,000; they are also considered expellees under German Federal Expellee Law.
The evacuation of German people from Central and Eastern Europe ahead of the Soviet Red Army advance during the Second World War was delayed until the last moment. Plans to evacuate people to present-day Germany from the territories controlled by Nazi Germany, including from the former eastern territories of Germany as well as occupied territories, were prepared by the German authorities only when the defeat was inevitable, which resulted in utter chaos. The evacuation in most of the Nazi-occupied areas began in January 1945, when the Red Army was already rapidly advancing westward.
The Oder–Neisse line is an unofficial term for the modern border between Germany and Poland. The line generally follows the Oder and Lusatian Neisse rivers, meeting the Baltic Sea in the north. A small portion of Polish territory does fall west of the line, including the cities of Szczecin and Świnoujście.
The Germany–Poland border is the state border between Poland and Germany, mostly along the Oder–Neisse line, with a total length of 467 km (290 mi). It stretches from the Baltic Sea in the north to the Czech Republic in the south.
Zakerzonia is an informal name for the territories of Poland to the west of the Curzon Line which used to have sizeable Ukrainian populations, including significant Lemko, Boyko populations, before the invasion of Poland by the Soviet Union and Nazi Germany in 1939, and were claimed as ethnically Ukrainian territories by Ukrainian nationalists in the aftermath of World War II. However, before 1939, the areas of Zakerzonia were mostly inhabited by Poles, who constituted about 70% of the population of this area. Ukrainians lived in a minority in Zakerzonia, constituting about 20% of the area's population.
Western Thought was a school of thought in Polish historical and political science. In the 1920s and 1930s Myśl zachodnia was organized in opposition to Ostforschung. A main center of Western Thought was the association Polski Związek Zachodni, founded in 1921.Unlike Germann Ostforschung, Polish western thought was not institutionalized and didn't constitute any real threat. Its influence was exaggerated by German scholars in order to fund and justify their own work.
