In short

The United Nations is a near-universal intergovernmental organisation created in 1945 to keep international peace, develop friendly relations, promote cooperation on economic and social problems, and harmonise state action, and it sits at the centre of a wider system of specialised agencies, funds, programmes, financial institutions and regional bodies. It matters because it is the only body whose decisions can be legally binding on all states (Security Council resolutions under Chapter VII), and because almost every rule that governs trade, health, aviation, labour, climate and nuclear material is made inside one of these organisations. In Indian universities it is a core unit of comparative politics and international relations papers and of UGC-NET Political Science; in competitive examinations (UPSC Prelims and Mains GS-II, state PSCs, CLAT/CUET) it is asked as both factual recall and analysis. In interviews — IFS boards, think tanks like ICWA, ORF, IDSA and CPR, UN and multilateral-bank internships, policy and research roles — the standard questions are on the veto, on reform, and on India's record and claim. Numerical questions do appear: voting thresholds, budget assessments and quota shares.

Explained

Origins: from the League to the UN

The six principal organs

  1. General Assembly (GA): all 193 members, one state one vote (Article 18). Deliberative, not legislative: its resolutions are recommendations, except on budget and internal matters, which bind. Elects non-permanent SC members, ECOSOC members, ICJ judges (jointly with the SC) and appoints the Secretary-General on SC recommendation. Six Main Committees; sessions open in September. Vijaya Lakshmi Pandit was the first woman President of the GA (1953).
  2. Security Council (SC): 15 members — 5 permanent (China, France, Russia, UK, US) and 10 elected for two-year, non-renewable terms. "Primary responsibility for the maintenance of international peace and security" (Article 24); its decisions bind all members (Article 25). Presidency rotates monthly in English alphabetical order.
  3. Economic and Social Council (ECOSOC): 54 members, three-year terms; coordinates the specialised agencies, the functional commissions (statistics, population, social development, narcotic drugs, status of women, science and technology) and the regional commissions (ESCAP, ECA, ECE, ECLAC, ESCWA); hosts the High-Level Political Forum that reviews the SDGs; grants consultative status to NGOs.
  4. International Court of Justice (ICJ): 15 judges, nine-year terms, no two of the same nationality, elected by absolute majority separately in the GA and the SC; seat at the Peace Palace, The Hague. Jurisdiction in contentious cases only over states (by special agreement, treaty clause, or Article 36(2) optional-clause declarations, which India has made with reservations) plus advisory opinions for authorised organs. Indian judges have included Nagendra Singh (President 1985–88), R.S. Pathak and Dalveer Bhandari. The Jadhav case (India v. Pakistan, 2019) found a breach of the Vienna Convention on Consular Relations and ordered effective review and reconsideration.
  5. Secretariat: headed by the Secretary-General, the "chief administrative officer" (Article 97), with a five-year renewable term in practice; Article 99 lets the SG bring any threat to peace before the Council — the office's main political lever. António Guterres's second term runs to 31 December 2026 and the selection of a successor was in progress during 2026, so the current incumbent should be checked.
  6. Trusteeship Council: suspended operations in 1994 after Palau, the last trust territory, became independent.

Key points

Formulas and examples

UNSC procedural vote: adopted if affirmative votes ≥ 9 of 15 (no veto applies)
UNSC substantive vote: adopted if affirmative votes ≥ 9 and negative votes by permanent members = 0
GA important question (Article 18(2)): adopted if YES ≥ (2/3) × (members present and voting); abstentions and absentees are excluded from the base
GA other question: adopted if YES > (1/2) × (members present and voting)
Charter amendment (Article 108): YES ≥ (2/3) × 193 in the GA, then ratification by ≥ (2/3) × 193 states, all five permanent members included
Article 19 loss of vote: arrears ≥ (assessment for year n−1) + (assessment for year n−2)
Assessed contribution: country's dues = (regular budget) × (its percentage in the current scale of assessments), where the percentage derives from GNI-based capacity to pay, with 22% ceiling and 0.001% floor
IMF special majority: a decision needs ≥ 85% of total voting power, so any member or bloc holding > 15% can block it

Example 1 - a Security Council substantive vote. A draft resolution imposing sanctions gets 10 in favour, 2 against (both elected members), 3 abstentions (one of them a permanent member).

Example 2 - an important question in the General Assembly. Of 193 members, 18 are absent and 15 abstain.

Example 3 - Article 19 arrears. A member is assessed US$1.20 million for each of 2024 and 2025 and owes US$2.60 million at the start of 2026.

Example 4 - India's assessed contribution. Take a regular budget of US$3,600 million and an Indian share of 1.10% in the current scale (the exact percentage must be read off the GA resolution in force).

Example 5 - the arithmetic of reform. For a Charter amendment adding permanent seats:
