The Potsdam Agreement was the agreement between 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 Axis powers, originally called the Rome–Berlin Axis and also known as the Rome-Berlin-Tokyo Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, the Kingdom of Italy, and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion.
The Charter of the United Nations (UN) is the foundational treaty of the United Nations, an intergovernmental organization. It establishes the purposes, governing structure, and overall framework of the UN system, including its six principal organs: the Secretariat, the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, and the Trusteeship Council.
The Atlantic Charter was a statement issued on 14 August 1941 that set out American and British goals for the world after the end of World War II, months before the US entered the war. The joint statement, later dubbed the Atlantic Charter, outlined the aims of the United States and the United Kingdom for the postwar world as follows: no territorial aggrandizement, no territorial changes made against the wishes of the people (self-determination), restoration of self-government to those deprived of it, reduction of trade restrictions, global co-operation to secure better economic and social conditions for all, freedom from fear and want, freedom of the seas, abandonment of the use of force, and disarmament of aggressor nations. The charter's adherents signed the Declaration by United Nations on 1 January 1942, which was the basis for the modern United Nations.
The Kingdom of Romania, under the rule of King Carol II, was initially a neutral country in World War II. However, Fascist political forces, especially the Iron Guard, rose in popularity and power, urging an alliance with Nazi Germany and its allies. As the military fortunes of Romania's two main guarantors of territorial integrity—France and Britain—crumbled in the Fall of France, the government of Romania turned to Germany in hopes of a similar guarantee, unaware that Germany, in the supplementary protocol to the 1939 Molotov–Ribbentrop Pact, had already granted its blessing to Soviet claims on Romanian territory.
The European theatre of World War II was one of the two main theatres of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin, and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May. On 5 June 1945, the Berlin Declaration proclaiming the unconditional surrender of Germany to the four victorious powers was signed. The Allied powers fought the Axis powers on two major fronts, but there were other fronts varying in scale from the Italian campaign, to the Polish Campaign, as well as in a strategic bombing offensive and in the adjoining Mediterranean and Middle East theatre.
Prince Paul of Yugoslavia, also known as Paul Karađorđević, was prince regent of the Kingdom of Yugoslavia during the minority of King Peter II. Paul was a first cousin of Peter's father, Alexander I.
A war of aggression, sometimes also war of conquest, is a military conflict waged without the justification of self-defense, usually for territorial gain and subjugation.
The history of the United Nations as an international organization has its origins in World War II beginning with the Declaration of St James's Palace. Taking up the Wilsonian mantle in 1944-1945, US President Franklin D. Roosevelt pushed as his highest postwar priority the establishment of the United Nations to replace the defunct League of Nations. Roosevelt planned that it would be controlled by the United States, Soviet Union, United Kingdom and China. He expected this Big Four would resolve all major world problems at the powerful Security Council. However the UN was largely paralyzed by the veto of the Soviet Union when dealing with Cold War issues from 1947 to 1989. Since then its aims and activities have expanded to make it the archetypal international body in the early 21st century.
The Declaration by United Nations was the main treaty that formalized the Allies of World War II and was signed by 47 national governments between 1942 and 1945. On 1 January 1942, during the Arcadia Conference, the Allied "Big Four"—the United States, the United Kingdom, the Soviet Union, and China—signed a short document which later came to be known as the United Nations Declaration, and the next day the representatives of 22 other nations added their signatures.
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, led by Nazi Germany, the Empire of Japan, and the Kingdom of Italy. Its principal members by the end of 1941 were the "Big Four" - United Kingdom, United States, Soviet Union, and China.
The Third Moscow Conference between the major Allies of World War II took place during October 18 to November 11, 1943, at the Moscow Kremlin and Spiridonovka Palace. It was composed of major diplomats, ministers and generals, who discussed cooperation in the war effort, and issued the Moscow Declaration.
The United Kingdom is a founding member of the United Nations and one of five permanent members of the UN Security Council.
The United Nations Conference on International Organization (UNCIO), commonly known as the San Francisco Conference, was a convention of delegates from 50 Allied nations that took place from 25 April 1945 to 26 June 1945 in San Francisco, California, United States. At this convention, the delegates reviewed and rewrote the Dumbarton Oaks agreements of the previous year. The convention resulted in the creation of the United Nations Charter, which was opened for signature on 26 June, the last day of the conference. The conference was held at various locations, primarily the War Memorial Opera House, with the Charter being signed on 26 June at the Herbst Theatre in the Veterans Building, part of the Civic Center. A square adjacent to the Civic Center, called "UN Plaza", commemorates the conference.
The neutral powers were countries that remained neutral during World War II. Some of these countries had large colonies abroad or had great economic power. Spain had just been through its civil war, which ended on 1 April 1939 —a war that involved several countries that subsequently participated in World War II.
The Anglo-Soviet Agreement was a declaration signed by the United Kingdom and the Soviet Union on 12 July, 1941 to cooperate in the war against Nazi Germany. Shortly after the beginning of Operation Barbarossa, the German invasion of the Soviet Union, both powers pledged to assist each other and not to make a separate peace with Germany.
The diplomatic history of World War II includes the major foreign policies and interactions inside the opposing coalitions, the Allies of World War II and the Axis powers, between 1939 and 1945.
The Government of the Kingdom of Yugoslavia in Exile was an official government-in-exile of Yugoslavia, headed by King Peter II. It evacuated from Belgrade in April 1941, after the Axis invasion of the country, and went first to Greece, then to Palestine, then to Egypt, and finally, in June 1941, to the United Kingdom. Hence, it is also referred to as the "Government in London".
Punishment for War Crimes was the title of a declaration issued by the representatives of eight Allied governments-in-exile and the Free French at the third Inter-Allied Conference at St James's Palace in London, United Kingdom, on 13 January 1942. It has been described as the "first milestone" towards the creation of an international legal framework for the prosecution of war crimes in German-occupied Europe during World War II.
