An intergovernmental organization (IGO) is a collective entity formed by multiple sovereign states, aimed at pursuing common interests and fostering cooperation on various issues such as trade, security, and development. IGOs, like the United Nations or European Union, enable member states to collaborate, negotiate agreements, and address challenges that transcend national borders. They provide a platform for dialogue and conflict resolution, enhancing international relations. IGOs can influence global governance and facilitate collective action in response to global challenges, promoting stability and cooperation among nations.
