Potsdam hosted the conference where the 1945 declaration on Japan was finalized.
The Potsdam Conference met from July 17 to August 2, 1945, in Potsdam, a city near Berlin in occupied Germany. The United States, the United Kingdom, and the Soviet Union were the principal Allied participants. During the meeting, the United States, Britain, and China issued the declaration calling for Japan’s unconditional surrender on July 26.
China’s leader Chiang Kai-shek was not physically present at the conference, but China joined the declaration through a message agreed with the other powers. The Soviet Union did not initially sign the Japan ultimatum because it was not yet at war with Japan; it later subscribed after entering the conflict.
The conference is often remembered mainly for its European settlement, but its Japan declaration had direct consequences in the Pacific. It described occupation, disarmament, and territorial limits and became a foundation for the surrender terms accepted by Japan.
