Chapter in a nutshell: The United Nations (UN) was founded on 24 October 1945 after World War II to maintain world peace, promote human rights, cooperation and development. It works through six principal organs โ the General Assembly, Security Council, ECOSOC, ICJ, Secretariat and Trusteeship Council โ and many specialised agencies (WHO, UNICEF, UNESCO).
1. Objectives of the UN
- Maintain international peace and security (settle disputes peacefully).
- Promote human rights and fundamental freedoms for all.
- Foster international cooperation on economic, social and humanitarian problems.
- Encourage social and economic development and better living standards.
2. The Six Principal Organs

| Secretariat | the administrative arm, headed by the Secretary-General |
