List of International Organizations and their Headquarters

An international organization (or intergovernmental organization) is formed by a treaty under international law and has its own legal identity. Examples include the United Nations and the World Health Organization. These organizations are mainly made up of member states but can also include other entities like NGOs.

The term “international organization” was first used by Scottish law professor James Lorimer in the 1870s. In 1935, Pitman B. Potter defined it as a group of nations working together for a common purpose. International organizations are often called intergovernmental organizations (IGOs) to differentiate them from international non-governmental organizations (INGOs) like the Red Cross. IGOs are established through treaties that give them legal status. It is important to distinguish IGOs from informal groupings of states, like the G7, which don’t have formal treaties. Also, some treaties do not create independent organizations but rather rely on member states for administration. Overall, these organizations play a key role in international relations and law.

International Organizations and Their Headquarters

Types and Purpose of Intergovernmental Organizations (IGOs)

Intergovernmental organizations (IGOs) vary in their functions, membership, and goals, which are usually stated in their founding treaties. They can serve as neutral forums for debate, resolve disputes, and promote peace. Some focus on specific issues, like environmental protection, human rights, or economic development.

Common Types of IGOs:

  • Global Organizations: Open to nations worldwide, like the United Nations, World Health Organization, and World Bank.
  • Cultural and Regional Organizations: Based on cultural or historical ties, such as the Commonwealth of Nations or the Arab League.
  • Economic Organizations: Focused on trade and economic policies, like the World Trade Organization and OPEC.
  • Educational Organizations: Centered on higher education and research, such as the United Nations University.
  • Health Organizations: Address global health issues collectively, like Partners in Population and Development.

Regional Organizations: Limited to specific regions, like the European Union and African Union, which have criteria for membership based on geography or political systems. Overall, IGOs play an essential role in fostering cooperation and addressing global challenges.

History of International Organizations

One early example of an international organization is the Congress of Vienna (1814–1815), which aimed to reshape Europe after Napoleon’s fall. Since the Peace of Westphalia in 1648, countries prioritized their sovereignty in decision-making.

The International Telecommunication Union, established in 1865, is the oldest international organization with a treaty and a permanent secretariat. The League of Nations, created on January 10, 1920, was the first general organization focused on various issues, primarily to maintain peace after World War I. The United Nations followed in 1945, becoming the main international organization, with key bodies like the Security Council and the General Assembly. Since 1940, the number of IGOs has grown from about 60 to around 350 by 1980, and this number has remained stable since then.
