Is the Potsdam Proclamation and the Potsdam Declaration the same thing?
No, the Potsdam Proclamation and the Potsdam Declaration are not the same thing. While they are related and issued during the same historical period, they are distinct documents.
The Potsdam Declaration was a joint statement issued on July 26, 1945, by the leaders of the Allied powers (United States, United Kingdom, and China) known as the Potsdam Conference. It outlined the terms and conditions of surrender for Japan, demanding their unconditional surrender and making provisions for the post-war occupation and reconstruction of Japan. The Potsdam Declaration ultimately led to Japan's surrender and the end of World War II.
On the other hand, the Potsdam Proclamation refers specifically to an ultimatum delivered by the United States to Japan on July 26, 1945, the same day the Potsdam Declaration was issued. The Potsdam Proclamation reiterated the demands outlined in the Potsdam Declaration, giving Japan a final opportunity to surrender or face "prompt and utter destruction." The Potsdam Proclamation was intended to compel the Japanese government to accept the terms of surrender laid out in the Potsdam Declaration.
