The United Nations: Introduction

This page providing an introduction to the United Nations (UN). It includes information about the UN's founding, its goals and functions, as well as the significance of the UN Charter as the legal basis for the organization.

Introduction

The United Nations (UN) is an intergovernmental organization founded in 1945 with the aim to maintain international peace and security, protect human rights, deliver humanitarian aid, promote sustainable development, and uphold international law.

The UN was established after World War II to replace the ineffective League of Nations. Its founding charter was signed by 51 member states, with the goal of preventing future wars by facilitating collective security and cooperation. Over the decades, the UN has grown to comprise 193 member states.

Headquartered in New York City, the UN has expanded its scope and activities significantly since its inception. While the Security Council holds primary responsibility for safeguarding peace, the organization carries out a wide array of functions through its various agencies and programs. From election monitoring to refugee relief to arms control treaties, the UN plays a vital role in global governance and cooperation.

Though not a world government, the UN provides a unique forum for multilateral diplomacy and upholding international law. Its successes, limitations and evolving challenges continue to make it an indispensable actor on the world stage.

UN Charter

The UN Charter serves as the legal basis and constitutional framework for the United Nations. The Charter was signed in June 1945 after extensive negotiations at the United Nations Conference on International Organization in San Francisco. Upon ratification by a majority of signatories, the Charter entered into force in October 1945.

The Charter establishes four key purposes for the UN:

  • To maintain international peace and security
  • To develop friendly relations among nations
  • To cooperate in solving international problems and in promoting respect for human rights
  • To be a centre for harmonizing the actions of nations

The UN Charter also lays out several guiding principles for the organization and its members, including:

  • All members are sovereign and equal
  • Members must settle disputes peacefully
  • No use of force against other member states
  • Non-intervention in domestic affairs
  • Members must provide assistance to the UN
  • The UN itself has no authority to intervene in matters within domestic jurisdiction

In signing the Charter, member states agree to accept obligations and rules that constrain their sovereignty. This includes refraining from the use of force in international relations and respecting decisions from UN bodies like the International Court of Justice. Members are also obligated to pay financial contributions to support the UN’s operations and activities.

The Charter established the UN as an intergovernmental organization governed by international law. By signing on, member states agree to be legally bound by the Charter’s provisions. This grants the UN a unique level of international legal identity and authority.

Principal Organs of the UN

The United Nations has six principal organs that carry out its work. These are:

  • The General Assembly (GA) - The GA is the main deliberative and policymaking organ of the UN. All 193 member states are represented in the GA, making it the most democratic and representative body of the UN. The GA discusses and makes recommendations on any matters within the scope of the UN Charter, except matters of peace and security that are under the Security Council’s consideration.

  • The Security Council (SC) - The SC has primary responsibility for maintaining international peace and security. It has 15 members, 5 of which are permanent (China, France, Russia, the United Kingdom and the United States) and 10 are non-permanent members elected by the GA for 2 year terms. The SC takes binding decisions related to peace and security matters.
  • The Economic and Social Council (ECOSOC) - ECOSOC is responsible for promoting economic, social, and environmental cooperation and development. It serves as the central forum for discussing international economic and social issues and formulating policy recommendations addressed to member states and the UN system.
  • The Trusteeship Council (TC) - The TC was established to supervise trust territories placed under the administration of member states. Its mission is complete and the TC is currently inactive.
  • The International Court of Justice (ICJ) - The ICJ is the principal judicial organ of the UN. It settles legal disputes submitted by states and gives advisory opinions on legal issues referred by authorized UN organs and agencies.
  • The Secretariat - The Secretariat carries out the day-to-day work of the UN. It provides studies, information, and facilities needed by the other UN organs to set policies and carry out decisions. The head of the Secretariat is the Secretary-General, who is appointed by the GA on the recommendation of the SC.

The Security Council

The Security Council (SC) is one of the principal organs of the United Nations and is charged with ensuring international peace and security. The SC has 15 members, including 5 permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 non-permanent members elected by the General Assembly for two-year terms.

The SC has primary responsibility for maintaining international peace and security. Under the UN Charter, all member states are obligated to comply with Council decisions. The SC takes the lead in determining the existence of a threat to the peace or act of aggression. It calls upon the parties to a dispute to settle it by peaceful means and recommends methods of adjustment or terms of settlement. In some cases, the Security Council can resort to imposing sanctions or even authorize the use of force to maintain or restore international peace and security.

The SC is the only UN body that can issue binding resolutions on member states. The permanent members have veto power over substantive but not procedural matters. This means that a permanent member can block the adoption of a resolution but cannot block its debate and consideration. The veto power of the permanent members has been criticized as limiting the effectiveness of the SC in some cases. However, the SC remains a critical component of the UN for addressing threats to international peace and security.

The General Assembly

The General Assembly (GA) is one of the six principal organs of the United Nations and the main deliberative, policymaking, and representative organ of the UN.

The GA is composed of all 193 Member States of the UN, each of which has equal representation and one vote. It provides a forum for multilateral discussion of international issues covered by the UN Charter.

The Assembly meets in regular annual sessions under a president elected from among the representatives. Special sessions can also be called for by the United Nations Security Council or a majority of UN members.

The GA has the authority to discuss and make recommendations on any matters within the scope of the UN Charter, except where a dispute or situation is being discussed by the Security Council. It can also discuss and make recommendations on matters brought to its attention by other UN organs.

The powers and functions of the General Assembly include:

  • Admit new Members to the UN
  • Elect members to other UN organs such as the Security Council
  • Appoint the Secretary-General on the recommendation of the Security Council
  • Receive and consider reports from other principal organs
  • Initiate studies and make recommendations to promote international cooperation and development
  • Approve the UN budget and assign the financial assessments of Member States
  • Elect the non-permanent members of the Security Council
  • Appoint the judges of the International Court of Justice
  • Coordinate the activities of the UN through participation of Member States

While the Assembly’s recommendations are not legally binding on Member States, its decisions become part of international customary law over time. The legitimacy, representative nature, and deliberative function of the GA make its recommendations compelling and meaningful in global governance.

The Secretariat

The Secretariat is the bureaucratic staff of the UN, headed by the Secretary-General. The Secretariat of the UN carries out the day-to-day work of the UN. It services the other principal organs of the UN and administers the programs and policies laid down by them.

The Secretariat is composed of international civil servants who represent the UN rather than any individual nation or government. Staff are recruited from member states, but employment contracts pledge staff to act independently of any government. The UN Charter describes the Secretary-General as the “chief administrative officer” of the Organization who shall act in that capacity in all meetings of the General Assembly, of the Security Council, of the Economic and Social Council and of the Trusteeship Council.

The functions of the Secretariat include:

  • Preparing the budget for the UN and the agendas for the major meetings of the principal UN organs
  • Providing studies, information, and facilities needed by UN bodies to make decisions
  • Administering peacekeeping operations
  • Mediating international disputes
  • Surveying economic and social trends
  • Interpreting speeches and translating documents into the UN’s official languages

The Secretariat thus performs a wide variety of international services central to the mandate of the UN in areas such as political affairs, law, development, and humanitarian assistance.

The Trusteeship Council

The Trusteeship Council was established to provide international supervision for 11 Trust Territories that had been placed under the administration of seven Member States, and ensure that adequate steps were taken to prepare the Territories for self-government and independence.

The Charter designated the Trusteeship Council as one of the main organs of the United Nations and assigned it the task of supervising the administration of Trust Territories placed under the Trusteeship System. Major goals of the System were to promote the advancement of the inhabitants of Trust Territories and their progressive development towards self-government or independence. The Trusteeship Council received reports from the Administering Authorities on the political, economic, social and educational advancement of the peoples of Trust Territories and examined petitions from and undertook periodic and other special missions to Trust Territories.

By 1994, all Trust Territories had attained self-government or independence. The Trusteeship Council suspended operation on 1 November 1994 with the independence of Palau, the last remaining United Nations Trust Territory, on 1 October 1994.

The Trusteeship Council has no remaining mandates and hence is currently inactive. However, under the Charter, it remains open for States responsible for administering trust territories to continue to use it. The Trusteeship Council was not formally abolished and continues to exist pursuant to the United Nations Charter’s Chapter XIII. Its future role and existence remain uncertain.

The International Court of Justice (ICJ)

The International Court of Justice (ICJ) is the principal judicial organ of the United Nations. It was established in 1945 by the UN Charter and began work in 1946. The court is located in the Peace Palace in The Hague, Netherlands.

The role of the ICJ is to settle legal disputes submitted by states and give advisory opinions on legal questions submitted by authorized UN organs and agencies. The ICJ is the successor of the Permanent Court of International Justice which functioned between 1922 and 1946.

Only states may be parties in contentious cases before the ICJ. This does not preclude private interests from being the subject of proceedings if a state brings them before the court. The ICJ’s judgements have binding force and are without appeal for parties concerned. In the event of a dispute as to the meaning or scope of a judgement, the ICJ interprets it upon request of any party.

The ICJ primarily resolves two types of disputes: contentious issues between states and requests for advisory opinions. The court’s contentious jurisdiction is based on the voluntary acceptance of the ICJ’s jurisdiction by the disputing states. In contentious cases, the court produces binding rulings between states that agree to submit to the ruling of the court. Advisory opinions are non-binding, but they are influential and widely respected interpretations of international law.

Overall, the International Court of Justice plays a key role in peaceful dispute resolution between states, and in clarifying and developing international law. Its judgements and advisory opinions carry great legal weight and moral authority. The ICJ provides a crucial forum for ensuring compliance with international agreements, reducing conflicts, and enabling the peaceful settlement of disputes.

The Economic and Social Council

The Economic and Social Council (ECOSOC) is one of the 6 principal organs of the United Nations established by the UN Charter to discuss a range of economic, social, cultural, educational, health and related matters and to undertake studies and make recommendations on these issues.

ECOSOC serves as the central forum for discussing international economic and social issues and formulating policy recommendations addressed to member states and the UN system. ECOSOC is made up of 54 member states elected by the General Assembly for 3 year terms. Members are chosen according to geographical representation with 14 seats allocated to African states, 11 to Asian states, 6 to Eastern European states, 10 to Latin American and Caribbean states and 13 to Western European and other states.

The key functions and responsibilities of ECOSOC include:

  • Promoting higher standards of living, full employment, and economic and social progress
  • Identifying solutions to international economic, social and health problems
  • Facilitating international cultural and educational cooperation
  • Encouraging universal respect for human rights and fundamental freedoms

Some of the major issues addressed by ECOSOC include poverty reduction, sustainable development, human rights, narcotic drugs, population issues, statistics, women’s rights and youth issues among others. ECOSOC undertakes studies and makes recommendations to member states and the UN system on these issues but does not have binding legal authority. However, ECOSOC’s recommendations serve an important role in setting the agenda and priorities for the UN’s work on social and economic development issues.

Conclusion

The United Nations is a formal institution created in 1945 by the UN Charter to govern international relations between member states. Its principal organs include the Security Council, General Assembly, Secretariat, Trusteeship Council, International Court of Justice, and Economic and Social Council.

The UN plays an important role in promoting international cooperation and establishing a legal framework for inter-state politics. Key provisions in the UN Charter like sovereignty equality and non-intervention constrain state actions and enable new forms of global politics. While UN organs have limited binding legal authority, the organization’s identity and influence in geopolitics is significant.

By providing a forum for cooperation and a basic code of conduct between nations, the UN system aims to prevent armed conflict and promote peace, security, development, and human rights worldwide. Despite imperfections, the UN has arguably helped limit inter-state wars and fosters dialogue for resolving disputes. With most countries participating, the UN helps shape modern norms and laws in international relations.
