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 between three of the Allies of World War II: the United Kingdom, the United States, and the Soviet Union after the war ended in Europe 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 the former German provinces of Silesia, Pomerania, and East Prussia, which were annexed by Poland and the Soviet Union. The idea to expel the Germans from the annexed territories had been proposed by Winston Churchill, in conjunction with the Polish and Czechoslovak exile governments in London at least since 1942. Polish prime minister Tomasz Arciszewski supported the annexation of German territory, but opposed the idea of expulsion, wanting instead to naturalize the Germans as Polish citizens and to assimilate them.
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. It was first proposed by The 1st Earl Curzon of Kedleston, the British Foreign Secretary, to the Supreme War Council in 1919 as a diplomatic basis for a future border agreement.
Drang nach Osten was the name for a 19th-century German nationalist intent to expand Germany into Slavic territories of Central and Eastern Europe. In some historical discourse, Drang nach Osten combines historical German settlement in Central and Eastern Europe, medieval military expeditions such as those of the Teutonic Knights, and Germanisation policies and warfare of modern German states such as those that implemented Nazism's concept of Lebensraum.
The "former eastern territories of Germany" refer in present-day Germany 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 Europe. In many of these territories, Germans used to be the dominant or sole ethnicity. 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 Potsdam Agreement after World War II in Europe on 2 August 1945 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 expelled to Germany, with their possessions being expropriated.
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, 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.
The Treaty of Zgorzelec between the Republic of Poland and East Germany (GDR) was signed on 6 July 1950 in Zgorzelec, Poland.
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 entirety of Germany was occupied and administered by the Allies of World War II from the Berlin Declaration on 5 June 1945 to the establishment of West Germany on 23 May 1949. Unlike occupied Japan, Germany was stripped of its sovereignty and former state: after Nazi Germany surrendered on 8 May 1945, four countries representing the Allies asserted joint authority and sovereignty through the Allied Control Council (ACC) under the Berlin Declaration of 5 June 1945 that led to the fall of the German Reich. At first, Allied-occupied Germany was defined as all territories of Germany before the 1938 Nazi annexation of Austria; the Potsdam Agreement on 2 August 1945 defined the new eastern German border by giving Poland and the Soviet Union all regions of Germany east of the Oder–Neisse line and divided the remaining "Germany as a whole" into four occupation zones, each administered by one of the Allies.
The presence of German-speaking populations in Central and Eastern Europe is rooted in centuries of history, with the settling in northeastern Europe of Germanic peoples predating even the founding of the Roman Empire. The presence of independent German states in the region, and later the German Empire as well as other multi-ethnic countries with German-speaking minorities, such as Hungary, Poland, Imperial Russia, etc., demonstrates the extent and duration of German-speaking settlements.
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 typical exception of multi-ethnic Austria where was ruled by German-speaking royal family of Habsburg and had a significant German-speaking land, into the German Empire. After the First World War, on 10 January 1920, Germany lost about 10% of its territory to its neighbours, and the Weimar Republic was formed 2 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.
Official relations between Poland and the United States on a diplomatic level were initiated in 1919 after Poland had established itself as a republic after 123 years of being under foreign rule from the Partitions of Poland. However, ties with the United States date back to the 17th century, when the Polish–Lithuanian Commonwealth was one of Europe's largest powers, and many Poles immigrated to the Thirteen Colonies. During the American Revolutionary War, the Polish military commanders Tadeusz Kościuszko and Casimir Pułaski contributed greatly to the Patriot cause, with Kościuszko becoming a national hero in America. Since 1989, Polish–American relations have been strong and Poland is one of the chief European allies of the United States, being part of both NATO and the European Union. There is a strong cultural appreciation between the two nations (Polonophilia). According to the US Department of State, Poland remains a "stalwart ally" and "one of strongest Continental partners in fostering security and prosperity, throughout Europe and the world." Poland was also one of four participating countries in the American-led Iraq War coalition in 2003.
The bilateral relations between Germany and Poland have been marked by an extensive and complicated history.
History of Pomerania (1945–present) covers the history of Pomerania during World War II aftermath, the Communist and since 1989 Democratic era.
The Recovered Territories or Regained Lands, also known as the Western Borderlands, and previously as the Western and Northern Territories, Postulated Territories and Returning Territories, are the former eastern territories of Germany and the Free City of Danzig that became part of Poland after World War II, at which time most of their German inhabitants were forcibly deported. The rationale for the term "Recovered" was that these territories formed part of the Polish state, and were lost by Poland in different periods over the centuries. It also referred to the Piast Concept that these territories were part of the traditional Polish homeland under the Piast dynasty, after the establishment of the state in the Middle Ages. Over the centuries, however, they had become predominantly German-speaking through the processes of German eastward settlement, political expansion, as well as language shift due to Germanisation of the local Polish, Slavic and Baltic Prussian population. Therefore, aside from certain regions such as West Upper Silesia, Warmia and Masuria, as of 1945 most of these territories did not contain sizeable Polish-speaking communities.
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.
After World War II both West Germany and East Germany were obliged to pay war reparations to the Allied governments, according to the Potsdam Conference. Other Axis nations were obliged to pay war reparations according to the Paris Peace Treaties, 1947. Austria was not included in any of these treaties.
The Germany–Poland border, the state border between Poland and Germany, is currently the Oder–Neisse line. It has a total length of 467 km (290 mi) and has been in place since 1945. It stretches from the Baltic Sea in the north to the Czech Republic in the south.
