United Nations (commonly known as the UN) is a global international organization founded on October 24, 1945, following the devastation of World War II, with the primary mandate to maintain international peace and security, develop friendly relations among nations, and promote international cooperation. Succeeding the ineffective League of Nations, the UN currently unites nearly all recognized sovereign states worldwide—totaling 193 member states.
Peace and Security: Preventing armed conflict, mediating international disputes through diplomatic channels, and deploying peacekeeping missions to stabilize post-conflict zones.
Human Rights and Sustainable Development: Safeguarding fundamental human freedoms, combating discrimination, eradicating extreme poverty, providing humanitarian relief, and executing the ambitious Sustainable Development Goals (SDGs).
General Assembly: The main deliberative, policymaking, and representative organ of the UN, comprising all member states (each holding a single vote) to debate global issues and adopt non-binding resolutions.
Security Council: The powerful executive organ bearing primary responsibility for maintaining international peace and security. It consists of 15 members, including five permanent veto-wielding powers—often known as the P5 (China, France, Russia, the United Kingdom, and the United States)—and ten rotating non-permanent members elected for two-year terms.
Secretariat: The administrative engine of the organization, headed by the Secretary-General, carrying out day-to-day operations, field missions, and research.
International Court of Justice (ICJ): The principal judicial organ of the UN, located in The Hague, Netherlands, which adjudicates legal disputes submitted by states and provides advisory opinions on legal questions.
Economic and Social Council (ECOSOC): The central platform coordinating economic, social, and environmental work across the vast network of UN specialized agencies.
Global Network: The UN system encompasses numerous autonomous specialized bodies and operational programs addressing specific global challenges, including the World Health Organization (WHO), UNESCO, UNICEF, the UN Development Programme (UNDP), and the UN High Commissioner for Refugees (UNHCR).
