The Potsdam Conference was held at Potsdam in the Soviet occupation zone from July 17 to August 2, 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, Prime Ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war.
The Potsdam Agreement 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 Declaration, or the Proclamation Defining Terms for Japanese Surrender, was a statement that called for the surrender of all Japanese armed forces during World War II. On July 26, 1945, United States President Harry S. Truman, United Kingdom Prime Minister Winston Churchill, and Chairman of China Chiang Kai-shek issued the document, which outlined the terms of surrender for the Empire of Japan, as agreed upon at the Potsdam Conference. The ultimatum stated that, if Japan did not surrender, it would face "prompt and utter destruction."
Japan was occupied and administered by the Allies of World War II from the surrender of the Empire of Japan on September 2, 1945, at the war's end until the Treaty of San Francisco took effect on April 28, 1952. The occupation, led by the American military with support from the British Commonwealth and under the supervision of the Far Eastern Commission, involved a total of nearly one million Allied soldiers. The occupation was overseen by the US General Douglas MacArthur, who was appointed Supreme Commander for the Allied Powers by the US President Harry S. Truman; MacArthur was succeeded as supreme commander by General Matthew Ridgway in 1951. Unlike in the occupations of Germany and Austria, the Soviet Union had little to no influence in Japan, declining to participate because it did not want to place Soviet troops under MacArthur's direct command.
The Yalta Conference, held 4–11 February 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union to discuss the postwar reorganization of Germany and Europe. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin. The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov palaces.
The Morgenthau Plan was a proposal to weaken Germany following World War II by eliminating its arms industry and removing or destroying other key industries basic to military strength. This included the removal or destruction of all industrial plants and equipment in the Ruhr. It was first proposed by United States Secretary of the Treasury Henry Morgenthau Jr. in a 1944 memorandum entitled Suggested Post-Surrender Program for Germany.
The Soviet–Japanese Neutrality Pact, also known as the Japanese–Soviet Non-aggression Pact, was a non-aggression pact between the Soviet Union and the Empire of Japan signed on April 13, 1941, two years after the conclusion of the Soviet-Japanese Border War. The agreement meant that for most of World War II, the two nations fought against each other's allies but not against each other. In 1945, late in the war, the Soviets scrapped the pact and joined the Allied campaign against Japan.
Following the termination of hostilities in World War II, the Allies were in control of the defeated Axis countries. Anticipating the defeat of Germany and Japan, they had already set up the European Advisory Commission and a proposed Far Eastern Advisory Commission to make recommendations for the post-war period. Accordingly, they managed their control of the defeated countries through Allied Commissions, often referred to as Allied Control Commissions (ACC), consisting of representatives of the major Allies.
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – the United Kingdom, United States, Soviet Union, and China.
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, ending the war. By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of Japan in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the US and the UK at the Tehran and Yalta Conferences.
Relations between the Soviet Unionand Japan between the Communist takeover in 1917 and the collapse of Communism in 1991 tended to be hostile. Japan had sent troops to counter the Bolshevik presence in Russia's Far East during the Russian Civil War, and both countries had been in opposite camps during World War II and the Cold War. In addition, territorial conflicts over the Kuril Islands and South Sakhalin were a constant source of tension. These, with a number of smaller conflicts, prevented both countries from signing a peace treaty after World War II, and even today matters remain unresolved.
The formation of the European Advisory Commission (EAC) was agreed on at the Moscow Conference on 30 October 1943 between the foreign ministers of the United Kingdom, Anthony Eden, the United States, Cordell Hull, and the Soviet Union, Vyacheslav Molotov, and confirmed at the Tehran Conference in November. In anticipation of the defeat of Nazi Germany and its allies this commission was to study the postwar political problems in Europe and make recommendation to the three governments, including the surrender of the European enemy states and the machinery of its fulfillment. After the EAC completed its task it was dissolved at the Potsdam Conference in August 1945.
The Moscow Conference of Foreign Ministers, also known as the Interim Meeting of Foreign Ministers, was held in Moscow between the foreign ministers of the United States, the United Kingdom, and the Soviet Union from December 16 to 26, 1945. They discussed the problems of occupation, establishing peace, and other Far Eastern issues.
The Soviet–Japanese War was a campaign of the Second World War that began with the Soviet invasion of Manchuria following the Soviet declaration of war against Japan on 8 August 1945. The Soviet Union and Mongolian People's Republic toppled the Japanese puppet states of Manchukuo in Manchuria and Mengjiang in Inner Mongolia, as well as northern Korea, Karafuto on the island of Sakhalin, and the Kuril Islands. The defeat of Japan's Kwantung Army helped bring about the Japanese surrender and the end of World War II. The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it was made apparent that the Soviet Union was not willing to act as a third party in negotiating an end to hostilities on conditional terms.
Council of Foreign Ministers was an organisation agreed upon at the Potsdam Conference in 1945 and announced in the Potsdam Agreement and dissolved upon the entry into force of the Treaty on the Final Settlement with Respect to Germany in 1991.
The aftermath of World War II saw the rise of two superpowers, the Soviet Union (USSR) and the United States (US). The aftermath of World War II was also defined by the rising threat of nuclear warfare, the creation and implementation of the United Nations as an intergovernmental organization, and the decolonization of Asia, Oceania, South America and Africa by European and East Asian powers, most notably by the United Kingdom, France, and Japan.
Government Aid and Relief in Occupied Areas (GARIOA) was a program under which the United States after the 1945 end of World War II from 1946 onwards provided emergency aid to the occupied nations of Japan, Germany, and Austria. The aid was predominantly in the form of food to alleviate starvation in the occupied areas.
The industrial plans for Germany were designs the Allies of World War II considered imposing on Germany in the Aftermath of World War II to reduce and manage Germany's industrial capacity.
The Berlin Declaration of 5 June 1945 or the Declaration regarding the defeat of Germany, had the governments of the United States, the Soviet Union, the United Kingdom, and France, acting on behalf of the Allies of World War II, jointly assume de jure "supreme authority" over Germany after its military defeat and asserted the legitimacy of their joint determination of issues regarding its administration and boundaries prior to the forthcoming Potsdam Conference.
The main issues of the United States foreign policy during the 1945–1953 presidency of Harry S. Truman include:
