United Nations

The United Nations (UN) is an intergovernmental organization established to maintain international peace and security, promote friendly relations among nations, foster international cooperation, protect human rights, and coordinate collective action on global challenges. Founded on 24 October 1945 following the entry into force of the Charter of the United Nations, the organization was created in the aftermath of the Second World War to prevent future conflicts and promote a rules-based international order. Headquartered in New York City, the United Nations comprises 193 member states and serves as the world's principal forum for multilateral diplomacy and international cooperation. It maintains additional major offices in Geneva, Vienna, and Nairobi.

The United Nations operates through six principal organs: the United Nations General Assembly, the United Nations Security Council, the United Nations Economic and Social Council (ECOSOC), the International Court of Justice (ICJ), the United Nations Secretariat, and the United Nations Trusteeship Council, although the latter has suspended active operations. The organization addresses a broad range of global issues, including peacekeeping, conflict prevention, humanitarian assistance, sustainable development, climate change, human rights, public health, international law, refugee protection, disaster relief, nuclear non-proliferation, and economic development. It also authorizes peacekeeping missions, administers sanctions through the Security Council, supports election monitoring, and coordinates international responses to humanitarian crises and armed conflicts.

The United Nations system comprises numerous specialized agencies, funds, programmes, and related organizations with distinct mandates. These include the World Health Organization (WHO), the International Monetary Fund (IMF), the World Bank, the United Nations Educational, Scientific and Cultural Organization (UNESCO), the International Civil Aviation Organization (ICAO), the International Maritime Organization (IMO), the Food and Agriculture Organization (FAO), the International Labour Organization (ILO), the United Nations Development Programme (UNDP), the United Nations Children's Fund (UNICEF), the United Nations High Commissioner for Refugees (UNHCR), and the United Nations Conference on Trade and Development (UNCTAD). Through these institutions, the United Nations supports international cooperation in fields including health, education, trade, aviation, labour standards, environmental protection, humanitarian relief, and sustainable development.

The United Nations works closely with international organizations such as the World Trade Organization (WTO), the Organisation for Economic Co-operation and Development (OECD), the Financial Stability Board (FSB), the Bank for International Settlements (BIS), and regional organizations including the European Union, the African Union, the Association of Southeast Asian Nations (ASEAN), and the Organization of American States (OAS). Guided by the principles of sovereign equality, peaceful dispute resolution, and international cooperation, the United Nations plays a central role in shaping global governance, promoting international law, advancing the Sustainable Development Goals (SDGs), and addressing transnational challenges affecting peace, security, development, and human welfare.
