The Big Four
The need for an international organization to replace the League of Nations was first stated officially on 30 October 1943, in the Moscow Declaration issued by these four nations. The Moscow Declaration, also known as the Declaration of the Four Nations, called for the establishment of a "general international organization, based on the principle of the sovereign equality of all peace-loving states, and open to membership by all such states, large and small, for the maintenance of international peace and security."
The United Nations was formally established on 26 June 1945, with the signing of the UN Charter by representatives of 50 countries. The Charter of the United Nations is the foundational treaty that establishes the purposes, governing structure, and overall framework of the UN system. The UN officially came into existence on 24 October 1945, after the required number of nations had ratified the Charter.

The Moscow Declaration
The Declaration on Austria expressed the determination of the UK, US, and Soviet Union to liberate Austria from German domination and restore its independence. They considered all changes enforced by Germany since 1938 as null and void and sought to establish political and economic security in Austria and neighboring states. Additionally, they acknowledged the atrocities, massacres, and mass executions perpetrated by Hitlerite forces and their responsibility in holding them accountable.

The Dumbarton Oaks Conference
The purpose of the conference was to draft a charter for a postwar international organization based on the principle of collective security. The conference was a follow-up to the Moscow Declaration of 1943, which recognized the need for such an organization to replace the League of Nations. The Four Policemen had agreed to this declaration, along with the need for an international organization, in October 1943.
The conference was held in two phases. The first phase, from August 21 to September 28, involved representatives of the Soviet Union, the United Kingdom, and the United States. The second phase, from September 29 to October 7, brought together representatives of the Republic of China, the United Kingdom, and the United States. This separation was necessary because the Russian and Chinese delegations could not meet at the same time and place.
The delegates agreed on a tentative set of proposals, including the establishment of a General Assembly of all member states and a Security Council consisting of the Big Four plus six members chosen by the Assembly. They also discussed which states would be invited to become members, the formation of the United Nations Security Council, and the right of veto for permanent members of the Security Council. However, two issues remained unresolved: the voting procedure in the Security Council and the Soviet pressure for the admission of all sixteen Soviet republics to the General Assembly.

The Yalta Conference
At the conference, Roosevelt, Churchill, and Stalin made several important decisions. They discussed the conditions under which the Soviet Union would enter the war against Japan, agreeing to grant the Soviets a sphere of influence in Manchuria and other territories in exchange for their participation in the Pacific theater. They also agreed to include France in the postwar governing of Germany and determined that Germany would assume some responsibility for reparations. The leaders discussed the future of Eastern Europe, with the Americans and British agreeing to "friendly" governments in Eastern European nations bordering the Soviet Union, while the Soviets pledged to allow free elections in all territories liberated from Nazi Germany.
Additionally, the Yalta Conference addressed the establishment of the United Nations. The Soviets agreed to join the UN and withdrew their claim that all 16 Soviet republics should have membership in the General Assembly. Roosevelt and Stalin agreed on a voting formula in the Security Council, including veto power for permanent members. The agreements reached at Yalta were later criticized, particularly regarding Stalin's failure to uphold his promise of free elections in Eastern European countries.

The San Francisco Conference
The conference was originally planned to be hosted by President Roosevelt, but he passed away on 12 April 1945, and the delegates held a commemorative ceremony in his memory. The conference was chaired by the heads of the delegations of the sponsoring countries, including Anthony Eden of Britain, Edward Stettinius of the United States, T. V. Soong of China, and Vyacheslav Molotov of the Soviet Union. Lord Halifax of the British delegation chaired the final plenary session and submitted the final text of the Charter to the assembly.
The United Nations Charter established the structure of the United Nations, with two main bodies: the General Assembly, composed of all member nations, and the Security Council, consisting of five permanent members (the US, the UK, the Soviet Union, China, and France) and six non-permanent members chosen by the Assembly. The Charter also provided for an 18-member Economic and Social Council, the International Court of Justice, a Trusteeship Council, and a Secretariat under a Secretary-General.
