Comprehensive Study Guide: The United Nations and World Order

Historical Context and Foundation of the United Nations

  • Geopolitical Milestones Leading to Creation:
    • Late Stage of World War II: The United Nations (UN) was conceived during the final phase of World War II, as the Allied powers sought to establish a permanent collective security mechanism to prevent future global conflagrations, avoid the institutional failures of the League of Nations, and organize the post-war world order.
    • The Yalta Conference (February 1945):
    • Location and Participants: Held in Yalta (Crimea), attended by the heads of state of the "Big Three" Allied powers:
      • The Soviet Union (represented by Joseph Stalin)
      • The United Kingdom (represented by Winston Churchill)
      • The United States (represented by Franklin D. Roosevelt)
    • Key Resolution: The Big Three formally agreed on the establishment of a new universal international organization dedicated to global peace and security, deciding on the voting formula in the proposed Security Council and issuing the call for a general conference to draft the founding charter.
    • The San Francisco Conference (April 25 – June 26, 1945):
    • Attended by delegates from 5050 nations (later joined by Poland as an original signatory, totaling 5151 founding member states).
    • The conference formally finalized, adopted, and proclaimed the Charter of the United Nations (Hiến chương Liên hợp quốc).
    • Official Inception and UN Day:
    • Date: October 24, 1945 (24/10/194524/10/1945).
    • Milestone: The UN Charter officially entered into legal force following ratification by the five permanent members of the Security Council (the United States, the Soviet Union, the United Kingdom, France, and China) and a majority of other signatory nations.
    • Commemoration: October 24 is recognized globally as United Nations Day.
