What was the July 1945 Allied proclamation that demanded Japan’s surrender called?

The July 1945 Allied proclamation that demanded Japan’s surrender was called the Potsdam Declaration.

The United States, the United Kingdom, and China issued it on July 26, 1945, during the Potsdam Conference. It called for the unconditional surrender of Japan’s armed forces and warned that refusal would bring “prompt and utter destruction.”

The declaration outlined broad postwar conditions, including the occupation of designated Japanese territory, disarmament, punishment of war criminals, and the removal of militarist influence. It also stated that Japan’s sovereignty would be limited to the home islands and other islands determined by the Allies.

The Soviet Union did not initially sign the proclamation because it was not yet at war with Japan. After entering the war against Japan in August, the Soviet government agreed to adhere to the declaration. Japan later accepted its terms, leading to the formal surrender ceremony.
