Intergovernmental Organizations (IGOs)

Intergovernmental organizations, also known as international governmental organizations: the type of organization most closely associated with the term ‘international organization’, these are organizations that are made up primarily of sovereign states (referred to as member states). Notable examples include the United Nations (UN), Organisation for Economic Co-operation and Development (OECD) Organization for Security and Co-operation in Europe (OSCE), Council of Europe (CoE), European Union (EU; which is a prime example of a supranational organization), and World Trade Organization (WTO). The UN has used the term “intergovernmental organization” instead of “international organization” for clarity.
