What was the July 26, 1945 Allied declaration demanding Japan’s surrender called?

The July 26, 1945 Allied declaration demanding Japan’s surrender was called the Potsdam Declaration.

The United States, the United Kingdom, and China issued the declaration during the Potsdam Conference in Germany. It called on Japan to surrender unconditionally and warned of “prompt and utter destruction” if it refused. The Soviet Union did not initially sign because it was still neutral in the war against Japan.

The document also outlined broad postwar conditions. Japan was to be stripped of its conquered territories, its military forces disarmed, and its sovereignty limited mainly to the home islands and other islands designated by the Allies.

The declaration did not explicitly state what would happen to Emperor Hirohito. That omission contributed to Japanese uncertainty, because preserving the imperial institution was a major concern for Japanese leaders. Japan eventually accepted the declaration’s terms in August, while making a condition concerning the emperor’s position.
