intergorvermental organisation is a

An intergovernmental organization (IGO) is an entity created by treaty, involving two or more nations, to work on issues of common interest. In contrast to non-governmental organizations (NGOs), which are private entities, IGOs are established by sovereign states, with rights and responsibilities agreed upon by their member governments. Member states of an IGO typically have equal representation and vote on policies and decisions that affect the entire group.

Examples of IGOs include:

1. United Nations (UN) - An international organization founded in 1945 to promote peace, security, and cooperation among countries.
2. European Union (EU) - A political and economic union of 27 European countries that are located primarily in Europe.
3. North Atlantic Treaty Organization (NATO) - A military alliance established in 1949 between North American and European countries for mutual defense against aggression.
4. World Health Organization (WHO) - A specialized agency of the UN responsible for international public health.
5. International Monetary Fund (IMF) - An organization of 190 countries working to foster global monetary cooperation and financial stability.

IGOs operate in various fields, including security, health, trade, environmental protection, and human rights, providing a platform for negotiation and cooperation amongst states.
