Deutsche Post 25th Anniversary of the Potsdam Agreement

DEUTSCHE POST (East Germany) on 2 August 1970 issued a First Day Cover triptych and special cancellation for the 25th anniversary of the Potsdam Agreements. The stamps featured the Cecilienhof Palace, Big Three Conference and Potsdam Agreement.

The Potsdam Agreement (Potsdamer Abkommen) 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 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.

The Potsdam Conference also established the (provisional) eastern borders of Germany at the Oder-Neisse line and the fate of the new Germany.In July 1950, the GDR would recognize this border as definitive (Görlitz Agreement). It was not until 1990 that the Federal Republic of Germany formally accepted this line as the eastern border of the new Germany.

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.
