🇺🇳 The United Nations — Establishment, Objectives, Organs & Functions
ICSE Class 10HistoryJune 2026
Why this chapter matters: The United Nations is the most important international organisation in the world today. In ICSE History, this chapter tests your understanding of the UN's establishment, its objectives, and the composition & functions of its principal organs — especially the General Assembly, Security Council, and International Court of Justice. Expect at least one 8-mark question on an organ's composition + functions, or a comparative question on the General Assembly vs Security Council.
1. Background — Why Was the UN Created?
The UN was created in the aftermath of World War II (1939–1945), the deadliest conflict in human history (~70–85 million deaths). The League of Nations (established 1920 after WWI) had failed to prevent WWII due to:
- Absence of major powers (USA never joined; USSR joined late but was expelled)
- Lack of enforcement power (no army; decisions required unanimous consent)
- Rise of aggressive dictatorships (Hitler's Germany, Mussolini's Italy, Militarist Japan)
World leaders resolved to create a stronger, more effective international organisation to maintain peace and prevent future wars.

2. Aims, Objectives & Principles of the UN
2.1 Purposes / Objectives of the UN (Article 1 of UN Charter)
- Maintain international peace and security — the primary purpose. Take collective measures to prevent and remove threats to peace.
- Develop friendly relations among nations — based on the principle of equal rights and self-determination of peoples.
- Achieve international cooperation — in solving economic, social, cultural, and humanitarian problems. Promote and encourage respect for human rights and fundamental freedoms.
- Be a centre for harmonising the actions of nations — to coordinate efforts towards achieving these common goals.
2.2 Principles of the UN (Article 2 of UN Charter)
- Sovereign equality — all member states are equal in the UN.
- Good faith fulfilment of obligations — members must carry out their Charter obligations in good faith.
- Peaceful settlement of disputes — all disputes must be resolved through peaceful means (negotiation, mediation, arbitration, judicial settlement).
- Refrain from threat or use of force — against the territorial integrity or political independence of any state.
- Assistance to the UN — members must assist the UN in any action it takes under the Charter.
- Non-intervention in domestic matters — the UN cannot intervene in matters that are essentially within a state's domestic jurisdiction (Article 2(7) — the sovereignty clause).
ICSE 2026 Insight: The most commonly asked question: "State any four objectives of the UN" or "Explain any four principles of the UN." Memorise the Preamble's opening line: "We the peoples of the United Nations, determined to save succeeding generations from the scourge of war..."
3. The Six Principal Organs of the UN
| Organ | Headquarters | Composition | Key Function |
|---|---|---|---|
| General Assembly | New York | All 193 member states (one vote each) | Deliberative body — discusses and makes recommendations on any matter within the Charter |
| Security Council | New York | 15 members (5 permanent + 10 non-permanent) | Maintenance of international peace and security — can impose sanctions, authorise military action |
| International Court of Justice (ICJ) | The Hague, Netherlands | 15 judges | Settles legal disputes between states; gives advisory opinions |
| Economic and Social Council (ECOSOC) | New York | 54 members (elected by GA for 3-year terms) | Coordinates economic, social, and humanitarian work of the UN |
| Secretariat | New York | ~40,000 staff (headed by the Secretary-General) | Administrative arm — carries out day-to-day operations of the UN |
| Trusteeship Council | New York | 5 permanent members of SC (inactive since 1994) | Oversaw decolonisation of trust territories (now suspended — all territories have achieved self-government) |
ICSE Focus: The syllabus requires you to study three organs in detail: General Assembly, Security Council, and International Court of Justice. The other three (ECOSOC, Secretariat, Trusteeship Council) are asked briefly or not at all.
4. The General Assembly (GA) — The World's Parliament
4.1 Composition
- Members: All 193 member states of the UN — each has one vote (principle of sovereign equality).
- Representation: Each member sends up to 5 delegates, but only one vote per country.
- President: Elected annually from among the member states (rotates among regional groups — African, Asia-Pacific, Eastern European, Latin American & Caribbean, Western European & Others).
- Sessions: Annual regular session from September to December (General Debate in the last week of September). Special/Emergency sessions can be called.
4.2 Functions and Powers of the General Assembly
| Category | Functions |
|---|---|
| Deliberative | Discuss any matter within the scope of the UN Charter (peace, security, human rights, development). Make recommendations to members or the Security Council (non-binding). |
| Financial | Approves the UN budget (assessed contributions from all members). Determines the scale of assessments (how much each member pays — based on GDP). For 2024–25, the budget is ~$3.6 billion (regular budget). |
| Admission / Suspension / Expulsion | Admits new members (on recommendation of Security Council). Can suspend or expel a member (on SC recommendation). |
| Elections | Elects the non-permanent members of the Security Council (10 out of 15). Elects judges of the ICJ (jointly with SC). Appoints the Secretary-General (on SC recommendation). Elects members of ECOSOC. |
| Amendments | Can amend the UN Charter (requires 2/3 majority vote in GA + ratification by 2/3 of members including all 5 permanent SC members). |
| Trusteeship | Exercises supervisory functions over the Trusteeship Council. |
| Peace and Security | Can discuss any peace/security issue and make recommendations (when SC is not handling it). Under Uniting for Peace Resolution (1950), GA can act if SC is paralysed by veto. |
4.3 Voting in the General Assembly
- One country, one vote — regardless of size, population, or wealth.
- Two-thirds majority required for "important questions" (peace & security, admission of members, budget, amendments, election of SC members).
- Simple majority for all other questions.
- Resolutions are NOT legally binding — they are recommendations. However, they carry moral and political weight.
4.4 Main Committees of the General Assembly
The GA has 6 Main Committees that handle specific agenda items before they reach the full Assembly:
- First Committee (DISEC) — Disarmament & International Security
- Second Committee (ECOFIN) — Economic & Financial
- Third Committee (SOCHUM) — Social, Humanitarian & Cultural
- Fourth Committee (SPECPOL) — Special Political & Decolonisation
- Fifth Committee (ACABQ) — Administrative & Budgetary
- Sixth Committee (LEGAL) — Legal
5. The Security Council (SC) — The UN's Enforcement Arm
Primary Responsibility: Maintenance of international peace and security. Its decisions are legally binding on all UN members (Article 25).
5.1 Composition of the Security Council
| Category | Number | Members (as of 2026) |
|---|---|---|
| Permanent Members (P5) | 5 | USA, United Kingdom, France, Russia, China These are the 5 major Allied powers of WWII. Each has veto power — can block any substantive resolution. |
| Non-Permanent Members | 10 | Elected by GA for 2-year terms. 5 from Africa & Asia; 2 from Latin America; 2 from Western Europe & Others; 1 from Eastern Europe. Current (2025–26): Albania, Brazil, Gabon, Ghana, Japan, Malta, Mozambique, Switzerland, UAE, Ecuador (rotate every 2 years). |
| Total | 15 |
5.2 Functions and Powers of the Security Council
| Category | Functions |
|---|---|
| Peace & Security (Chapter VI — Pacific Settlement) | Investigate any dispute that threatens international peace. Call on parties to settle disputes peacefully (negotiation, mediation, arbitration). Offer good offices or recommend terms of settlement. |
| Enforcement Action (Chapter VII — Coercive Measures) | If peaceful means fail, the SC can: • Impose sanctions (economic, diplomatic, arms embargoes) — e.g., Iran, North Korea • Authorise military action ("all necessary means") — e.g., Kuwait 1991, Libya 2011 • Establish peacekeeping operations (Blue Helmets) — e.g., UNIFIL (Lebanon), MINUSMA (Mali) • Refer cases to the International Criminal Court (ICC) — e.g., Darfur 2005 |
| Admission of Members | Recommends admission of new members to the GA (the GA then votes). |
| Appointment of Secretary-General | Recommends a candidate to the GA (the GA then appoints). |
| Election of ICJ Judges | Votes jointly with the GA to elect ICJ judges. |
5.3 Veto Power — The Most Criticised Feature
- What is it? Any of the 5 permanent members can vote "No" on a substantive resolution and block it — even if the other 14 members vote in favour.
- Procedural matters: Veto does NOT apply (needs 9/15 votes). But what counts as "procedural" is itself subject to veto (the "double veto" problem).
- Abstention: A permanent member can abstain without vetoing (this is common — e.g., India-related resolutions where Russia/China abstain).
- History: USSR used veto ~120 times during the Cold War. USA has vetoed ~80+ times (most on Israel-related resolutions). China has vetoed ~15+ times. Russia vetoed ~25+ times (including on Syria, Ukraine).
- Criticism: Veto power is undemocratic — it reflects the power structure of 1945, not 2026. P5 rarely vetoes on matters affecting their own interests. Reforming the veto is a major demand of the Global South.
5.4 Peacekeeping — The UN's Most Visible Activity
- UN Peacekeeping: Deployed to help countries transition from conflict to peace. Authorised by SC, troops contributed voluntarily by member states (not a standing UN army).
- Three Principles: (1) Consent of parties, (2) Impartiality, (3) Non-use of force except in self-defence and defence of the mandate.
- Current missions: ~12 active missions (down from ~16 in 2015). Largest: MINUSMA (Mali), MONUSCO (DRC), UNMISS (South Sudan).
- Blue Helmets: ~70,000 troops from ~120 countries. India is the 3rd largest troop contributor (after Bangladesh and Pakistan).
- Nobel Peace Prize: UN Peacekeeping Forces have won the Nobel Peace Prize (1988).
ICSE Exam Hotspot: You must know the 5 permanent members (P5) and their veto power. A common 8-mark question: "Describe the composition and functions of the Security Council. What is the veto power and why is it criticised?"
5.5 Security Council Reform — The Demand
- Why reform? The SC represents the world of 1945 (P5 = WWII victors), not 2026. Africa (54 countries) has NO permanent seat. Latin America, Asia, and the Arab world are underrepresented.
- G4 Nations — India, Japan, Germany, Brazil — demand permanent seats (with or without veto).
- Uniting for Consensus (Coffee Club) — Italy, Pakistan, South Korea, Canada, Mexico, Argentina — oppose expansion of permanent seats; prefer elected 2-year seats.
- African Union position — demands 2 permanent seats for Africa (with veto).
- Current status: Intergovernmental negotiations (IGN) ongoing since 2008. No consensus reached. Any Charter amendment needs 2/3 GA + all 5 P5 ratification — so P5 can block their own reduction in power.
6. International Court of Justice (ICJ) — The World Court
Fact: The ICJ is the principal judicial organ of the UN. It replaced the Permanent Court of International Justice (PCIJ) which operated under the League of Nations. The ICJ Statute is an integral part of the UN Charter.
6.1 Composition
- Number of judges: 15 judges, elected for 9-year terms (renewable).
- Election: By absolute majority in both the General Assembly AND the Security Council (simultaneous voting — candidates must get majority in both).
- Geographical distribution: 3 from Africa, 2 from Latin America, 3 from Asia, 5 from Western Europe & Others, 2 from Eastern Europe (unofficial convention).
- Qualifications: Judges must be persons of high moral character who qualify for the highest judicial offices in their own countries or are jurists of recognised competence in international law.
- The P5 convention: Each permanent member of the SC (USA, UK, France, Russia, China) ALWAYS has a judge on the ICJ (not legally required, but a diplomatic convention).
- President & Vice-President: Elected by the judges for a 3-year term (renewable).
- No two judges from the same nationality — ensures diversity.
- Ad hoc judges: If a party to a case does not have a judge of its nationality on the bench, it can appoint an ad hoc judge for that case only.
6.2 Jurisdiction of the ICJ
| Type | What It Means | Examples |
|---|---|---|
| Contentious Jurisdiction | Settles legal disputes between states only (individuals, NGOs, or corporations CANNOT approach the ICJ directly). Both parties must consent to the court's jurisdiction. | India vs Pakistan (Kulbhushan Jadhav — 2017, India won; ICJ ruled Jadhav's Vienna Convention rights were violated). India vs Pakistan (Kashmiri — Rann of Kutch arbitration, 1968). |
| Advisory Jurisdiction | Gives advisory opinions on legal questions referred by authorised UN organs (GA, SC, ECOSOC, Trusteeship Council) or specialised agencies (WHO, UNESCO, ILO). Opinions are NOT binding — but carry great legal weight. | Advisory on Chagos Islands (2019) — UK's detachment of Chagos from Mauritius was unlawful. Advisory on Nuclear Weapons (1996) — threat/use of nuclear weapons generally contrary to international law. |
6.3 How a Case Reaches the ICJ
- Application filed — by one or both states to the ICJ Registry.
- Written proceedings — both parties submit written memorials and counter-memorials.
- Oral proceedings — public hearings where lawyers argue the case.
- Judgment — delivered in open court by majority vote. Judges may write separate (concurring or dissenting) opinions.
- Binding & final — the ICJ's judgment is binding on the parties and there is no appeal. If a party does not comply, the other party can approach the Security Council.
6.4 Compulsory vs Optional Jurisdiction
- Compulsory (treaties): If states have signed a treaty that includes an ICJ dispute-resolution clause (e.g., Vienna Convention on Consular Relations), the ICJ automatically has jurisdiction.
- Optional Clause (Article 36(2)): States can declare that they accept ICJ jurisdiction as compulsory — but many states (including India) have made such declarations with reservations (excluding certain types of disputes). India's declaration excludes disputes with Commonwealth countries, treaty partners, and matters within India's domestic jurisdiction.
6.5 India and the ICJ
- India has been a member of the ICJ since 1945 (though the ICJ started in 1946).
- Indian judges on the ICJ: Sir Benegal Narsing Rau (1952–1953), Nagendra Singh (1973–1988 — also served as President 1985–1988), R.S. Pathak (1989–1991), Dalveer Bhandari (2012–present; re-elected in 2018 for a 2nd term ending 2027).
- Kulbhushan Jadhav case (2017): India filed a case against Pakistan for denying consular access to Jadhav (sentenced to death by Pakistani military court). ICJ ruled in India's favour — Pakistan must provide "effective review and reconsideration" of the sentence and grant consular access.
- Enrica Lexie case (2015): Italy vs India — dispute over the killing of Indian fishermen by Italian marines. PCA (Permanent Court of Arbitration) — not ICJ — ruled that India can prosecute the marines but Italy has jurisdiction over the ship.

From my 80/80 History exam (ICSE 2026): The United Nations chapter is purely factual — there's no analysis required beyond memorising compositions and functions. My strategy: (1) General Assembly vs Security Council comparison tables — this single table answers 80% of the comparative questions. (2) Composition = marks — for every organ, memorise the number of members, term, voting, and how they're selected. This is the most commonly tested "8-mark" question pattern. (3) Security Council reform — this is the only "current affairs" element. Know the G4 (India, Japan, Germany, Brazil) and Coffee Club opposition. The fact that P5 can veto their own reform is the key insight. (4) Kulbhushan Jadhav case — India-vs-Pakistan at ICJ is a favourite "India and the ICJ" question. Remember: consular access, Vienna Convention, ICJ ruled in India's favour. (5) Specialised agencies — a guaranteed 2-marker. Know WHO (Geneva), UNESCO (Paris), UNICEF (NY), ILO (Geneva), FAO (Rome). (6) Remember: 24 Oct 1945 — this is the single most important date in the chapter. Good luck!
