Learn the Concept

All

The United Nations (UN), founded in 1945, is the world's central international organisation for peace, security and cooperation — the successor to the failed League of Nations and the cornerstone of the post-WWII order. Fix the significance: created in the aftermath of the Second World War to “save succeeding generations from the scourge of war”, the UN was established by the UN Charter signed at San Francisco (1945). Learning from the League's weaknesses, it gave real power to a Security Council with five permanent, veto-wielding members, included the great powers (notably the USA), and built a wide system of specialised agencies. It maintains international peace, promotes human rights, development and decolonization, and remains the principal forum of world diplomacy — with India a founder member and active participant.

In One Line
  • Founded: 1945, by the UN Charter signed at San Francisco; HQ in New York.
  • Purpose: maintain peace & security; promote human rights, development, cooperation.
  • Key organs: General Assembly, Security Council (5 permanent veto members), ICJ, Secretariat, ECOSOC.
  • Improvement on the League: great powers included, a Council with teeth, wide agencies.
Glossary (define-on-first-use)
  • UN Charter: the founding treaty of the United Nations (1945).
  • Security Council: the UN's peace-and-security organ; 5 permanent + 10 rotating members.
  • Veto: the power of each of the 5 permanent members (P5) to block a Council decision.
  • General Assembly: the body of all member states, each with one vote.
  • Specialised agencies: bodies like WHO, UNESCO, UNICEF, FAO, ILO under the UN system.

1. Background & founding

  • Determined to avoid the League's failure and another world war, the Allies planned a new body during WWII (the Atlantic Charter, 1941; the “United Nations” declaration, 1942; Dumbarton Oaks and Yalta). The UN Charter was signed at the San Francisco Conference (June 1945) and the UN formally came into being on 24 October 1945 (UN Day), with its headquarters in New York.

2. Principal organs

  • The UN has six main organs: the General Assembly (all members, one vote each); the Security Council (primary responsibility for peace — five permanent members, the USA, USSR/Russia, UK, France, China (the P5), with the veto, plus ten elected members); the International Court of Justice (The Hague); the Secretariat (headed by the Secretary-General); the Economic and Social Council (ECOSOC); and the (now dormant) Trusteeship Council.

3. Functions & agencies

  • The UN works to maintain peace (peacekeeping, sanctions, mediation), promote human rights (the Universal Declaration of Human Rights, 1948), advance development, health and education through specialised agencies (WHO, UNESCO, UNICEF, FAO, ILO, World Bank, IMF), and it supported decolonization. Its goals now include the Sustainable Development Goals.

4. Significance & critique

  • The UN has helped prevent a third world war, provided a universal forum, and done vast humanitarian and development work. But it is criticised for the P5 veto (which can paralyse the Council), unrepresentative structure, and limited enforcement power — fuelling calls for reform, including a permanent seat for India. It remains the indispensable institution of the modern international order.

Security CouncilPeace & security; P5 veto
ICJ (The Hague)Settles legal disputes

Key Facts to Remember
  • UN founded 1945 (Charter signed San Francisco; UN Day = 24 October); HQ New York.
  • Six organs; the Security Council has primary peace responsibility.
  • P5 (permanent, veto) = USA, Russia, UK, France, China.
  • UDHR 1948; specialised agencies: WHO, UNESCO, UNICEF, FAO, ILO.
  • Criticised for the veto & structure; India seeks a permanent seat.
Connect the Dots
  • League of Nations: the failed predecessor (previous leaf).
  • World War II: the catastrophe that prompted the UN (earlier leaf).
  • Decolonization: the process the UN supported (earlier leaf).
  • Cold War: the rivalry that often paralysed the Council.

Prepare for the Exam — Prelims

Prelims

Tested on 1945/San Francisco/UN Day, the six organs, the P5 veto, the UDHR (1948), and the specialised agencies.

High-probability areas
  • UN founded 1945; Charter signed at San Francisco; HQ New York.
  • UN Day = 24 October.
  • P5 (veto) = USA, Russia, UK, France, China.
  • UDHR adopted 1948; ICJ at The Hague.
  • Agencies: WHO, UNESCO, UNICEF, FAO, ILO.
Common traps
  • UN = 1945 (League = 1920).
  • Security Council = peace; veto held by the P5 only.
  • ICJ at The Hague; HQ (overall) at New York.
  • India is a founder member, seeking a permanent seat.
Revision tip: 1945 San Francisco → 6 organs → P5 veto → UDHR 1948 → agencies → reform/India.

How to Write the Answer

Mains
Worked example — decoding the question

“The United Nations learned from the mistakes of the League of Nations.” Discuss. (15)
“Discuss” = compare the two, showing how the UN corrected the League's flaws.

Introduction · ~20%
Note the UN's founding (1945) as the League's stronger successor.
Body · ~60%
Improvements: the great powers (incl. USA) joined; the Security Council has real enforcement power; a wide system of agencies; majority (not unanimity) decisions. But the P5 veto introduced its own paralysis during the Cold War. Mention functions: peace, human rights, development, decolonization.
Conclusion · ~20%
The UN is a stronger body than the League, yet still needs reform.
10-mark: ~150 words · ~7 min
15-mark: ~250 words · ~12 min
Common mistakes
