The UN: origins, Charter, principal organs

From the Atlantic Charter to San Francisco

The United Nations was not improvised in 1945; it was the product of a wartime drafting chain. The Atlantic Charter (14 August 1941), agreed by Franklin Roosevelt and Winston Churchill aboard warships off Newfoundland, articulated the post-war principles of self-determination and collective security. The term "United Nations" was coined in the Declaration by United Nations (1 January 1942), signed by 26 states then at war with the Axis. The institutional blueprint was hammered out at Dumbarton Oaks (August–October 1944), where the United States, the United Kingdom, the Soviet Union and China sketched the organs and the Security Council's primacy. The veto formula was settled at the Yalta Conference (February 1945).

The United Nations Conference on International Organization convened in San Francisco from 25 April to 26 June 1945, attended by 50 states. The Charter of the United Nations was signed on 26 June 1945 and entered into force on 24 October 1945 after ratification by the five permanent members and a majority of signatories—hence United Nations Day. Poland signed later, making 51 original members. India, though not yet independent, was an original signatory, having been a founding member by virtue of its separate League of Nations membership.

The Charter's structure

The Charter comprises a Preamble and 111 Articles in 19 Chapters, plus the annexed Statute of the International Court of Justice. Key load-bearing provisions a candidate must retain:

• Article 1 states the purposes: maintain international peace and security, develop friendly relations, achieve international cooperation, and be a centre for harmonizing actions.
• Article 2 sets the principles: sovereign equality (2.1), good-faith fulfilment of obligations (2.2), peaceful settlement of disputes (2.3), prohibition on the threat or use of force (2.4), and the domestic jurisdiction clause (2.7) barring UN intervention in matters essentially within domestic jurisdiction.
• Chapter VI governs pacific settlement of disputes; Chapter VII authorizes enforcement action against threats to the peace, breaches of the peace and acts of aggression, including sanctions (Article 41) and military measures (Article 42).
• Article 51 preserves the inherent right of individual and collective self-defence until the Security Council acts.
• Article 103 establishes the supremacy of Charter obligations over conflicting treaty obligations.

Crucially, peacekeeping appears nowhere in the text; Dag Hammarskjöld famously located it in a notional "Chapter Six and a Half." Amendment requires a two-thirds Assembly vote and ratification by two-thirds of members including all five permanent members (Articles 108–109)—the structural reason Security Council reform has stalled since the only successful enlargement of ECOSOC and the Council in 1965 and 1973.

The six principal organs

Article 7 establishes six principal organs. Each carries a distinct mandate and composition that examiners test for precise recall.

The General Assembly is the plenary body where all member states sit with one vote (Article 18). Important questions—peace and security, budget, membership—require a two-thirds majority; others a simple majority. Its powers are recommendatory, but the "Uniting for Peace" resolution (Resolution 377A, 3 November 1950) allows it to act on collective security when the Security Council is deadlocked by a veto—invoked over Korea (1950), Suez and Hungary (1956), and Ukraine (2022).

The Security Council has 15 members: five permanent (China, France, Russia, the UK, the US) holding the veto under Article 27(3), and ten non-permanent elected for two-year terms by the Assembly on equitable geographic distribution (the 1963 amendment, effective 1965, raised non-permanent seats from six to ten). It bears "primary responsibility" for peace and security (Article 24); its decisions bind all members under Article 25.

The Economic and Social Council (ECOSOC) has 54 members and coordinates the UN's economic, social and specialized agency work. The Trusteeship Council suspended operations on 1 November 1994 after Palau, the last trust territory, gained independence.

The International Court of Justice, seated at The Hague, is the principal judicial organ; its 15 judges serve nine-year terms, elected concurrently by the Assembly and Council. The Secretariat, headed by the Secretary-General (appointed by the Assembly on the Council's recommendation, Article 97), services the organization; Article 100 guarantees its international, independent character.

Why this matters for the exam

This lesson feeds UPSC GS Paper II (international institutions, their structure and mandate) and the international-organization sections of FSOT, CSS (Current Affairs / International Relations) and BCS. The recall tested is exact: which organ has 15 members versus 54, which article carries the veto (27.3), which the use-of-force ban (2.4), and which resolution bypasses Council paralysis (377A). PYQs repeatedly ask candidates to distinguish recommendatory Assembly powers from binding Council decisions under Article 25, and to explain why the domestic-jurisdiction clause (2.7) limits humanitarian intervention. Prelims-style questions probe dates—24 October 1945, the 1965 enlargement, the 1994 Trusteeship suspension—while Mains and essay questions demand an argued position on reform. Retain a compact authority map: Article 1 (purposes), 2 (principles), 7 (organs), 25 (binding decisions), 27 (voting), 51 (self-defence), 103 (supremacy), 108–109 (amendment). Pair each fact with a dated instance; examiners reward specificity over generality.
