The Potsdam Agreement (German: Potsdamer Abkommen) was the agreement between three of the Allies of World War II, the United Kingdom, the United States, and the Soviet Union. It concerned the military occupation and reconstruction of Germany, its borders, the status of its former eastern territories, and the entire European Theatre of War territory. It also addressed Germany's demilitarisation, reparations and the prosecution of war criminals.
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 It was superseded by the Treaty on the Final Settlement with Respect to Germany signed on 12 September 1990.
After the Second World War (1939–45), and the Tehran, Casablanca and Yalta Conferences, the Allies by the Berlin Declaration of June 5, 1945, had assumed supreme authority over Germany. In the Three Power Conference of Berlin (formal title of the Potsdam Conference) from 17 July to 2 August 1945, they agreed to and adopted the Protocol of the Proceedings, August 1, 1945, signed at Cecilienhof Castle 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 Provisional Government of the French Republic agreed with reservations on August 4.
