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 on 1 August 1945. 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 in the conference but formally still one of powers occupying Germany. Executed as a communiqué, the agreement was not a peace treaty according to international law, although it created accomplished facts. It was superseded by the Treaty on the Final Settlement with Respect to Germany signed on 12 September 1990. As De Gaulle had not been invited to the Conference, the French resisted implementing the Potsdam Agreements within their occupation zone. In particular, the French refused to resettle any expelled Germans from the east. Moreover, the French did not accept any obligation to abide by the Potsdam Agreement in the proceedings of the Allied Control Council; in particular resisting all proposals to establish common policies and institutions across Germany as a whole, and anything that they feared might lead to the emergence of an eventual unified German government. Overview After the end of World War II in Europe (1939–45), and the decisions of the earlier Tehran, Casablanca and Yalta Conferences, the Allies assumed supreme authority over Germany by the Berlin Declaration of June 5, 1945. At the Potsdam Conference the Western Allies were presented with Stalin's fait accompli awarding Soviet-occupied Poland the river Oder as its western border, placing the entire Soviet Occupation Zone east of it (with the exception of the Kaliningrad enclave), including Pomerania, most of East Prussia, and Danzig, under Polish administration. The German population who had not fled were expelled and their properties acquisitioned by the state. President Truman and the British delegations protested at these actions. The Three Power Conference took place from 17 July to 2 August 1945, in which they adopted the Protocol of the Proceedings, August 1, 1945, signed at Cecilienhof Palace in Potsdam. The signatories were General Secretary Joseph Stalin, President Harry S. Truman, and Prime Minister Clement Attlee, who, as a result of the British general election of 1945, had replaced Winston Churchill as the UK's representative. The
