The United Nations (UN) is the world’s largest and most influential international organization, established in 1945 after the devastation of World War II. Its primary purpose is to maintain international peace and security, promote human rights, support social and economic development, and uphold international law. With 193 member states, the UN plays a vital role in addressing global challenges such as climate change, conflict, humanitarian crises, and sustainable development.
In this article, we will explore the structure of the UN, its main organs, specialized agencies, and how it functions as a central platform for cooperation among nations.

1. The Structure of the United Nations

2. The Six Principal Organs of the United Nations
2.1 The General Assembly
- The General Assembly (GA) is the main deliberative body of the UN, where all 193 member states have equal representation and one vote each.
- It discusses important global issues, such as international peace, economic development, and human rights.
- While its resolutions are not legally binding, they carry strong moral and political weight.
2.2 The Security Council
- The UN Security Council (UNSC) is responsible for maintaining international peace and security.
- It has 15 members: 5 permanent members (United States, United Kingdom, France, Russia, and China) with veto power, and 10 non-permanent members elected for two-year terms.
- The UNSC can authorize peacekeeping missions, impose sanctions, and approve the use of military force when necessary.
2.3 The International Court of Justice (ICJ)
- Based in The Hague, Netherlands, the ICJ is the UN’s principal judicial organ.
- It settles legal disputes between states and gives advisory opinions on international law.
- Only states, not individuals, can bring cases before the ICJ.
2.4 The Secretariat
- The Secretariat carries out the daily work of the UN.
- It is headed by the Secretary-General, who serves as the organization’s chief administrative officer and symbolic leader.
- The Secretariat supports peacekeeping operations, prepares reports, and coordinates international conferences.
2.5 The Economic and Social Council (ECOSOC)
- ECOSOC promotes international economic and social cooperation and development.
- It coordinates the work of specialized agencies such as the World Health Organization (WHO), International Monetary Fund (IMF), and UNESCO.
- It serves as a forum for discussing global economic, social, and environmental issues.
2.6 The Trusteeship Council
- Originally established to oversee trust territories and help them achieve self-governance.
- It suspended operations in 1994 after Palau, the last trust territory, gained independence.
- Today, it exists only formally and has no active role.
3. Specialized Agencies and Programs
Beyond the six main organs, the UN system includes specialized agencies, funds, and programs that address specific global challenges. Some of the most notable include:
- World Health Organization (WHO): Coordinates international health efforts and responds to pandemics.
- United Nations Educational, Scientific and Cultural Organization (UNESCO): Promotes education, culture, and science.
- United Nations Children’s Fund (UNICEF): Provides humanitarian aid and protection for children worldwide.
- World Food Programme (WFP): Delivers food assistance to countries affected by crises.
- International Monetary Fund (IMF) and World Bank: Support global financial stability and development projects.
4. The Role of the Secretary-General
The Secretary-General serves as the head of the Secretariat and represents the UN globally. Often described as the “world’s top diplomat,” the Secretary-General plays a crucial role in mediation, conflict resolution, and advocating for peace. The current Secretary-General (as of 2025) is António Guterres, from Portugal.
5. Importance of the United Nations Today
The UN remains central to international cooperation in the 21st century. Some of its most critical roles include:
- Peacekeeping: Deploying missions to conflict zones.
- Humanitarian Aid: Assisting refugees, disaster victims, and vulnerable populations.
- Climate Action: Leading initiatives to combat climate change through agreements like the Paris Climate Accord.
- Human Rights Protection: Monitoring and promoting universal human rights standards.
Conclusion
The United Nations and its structure form the backbone of global governance, ensuring cooperation among nations in pursuit of peace, stability, and sustainable development. While the UN faces challenges such as political divisions and limited enforcement powers, it continues to serve as the most important forum for addressing worldwide problems.
