One of the key features of modern international relations and international law is the significant increase in the role of international organizations. International organizations play a crucial role not only in regulating cooperation between states but also in ensuring global peace, security, socio-economic development, and the protection of human rights. Their number and diversity, especially after World War II, have grown sharply: by the beginning of the 21st century, there are over 4,000 international organizations, of which approximately 300 are intergovernmental.

The emergence of international organizations is associated with the ongoing needs of humanity and the desire of nations and states for integration. Additionally, they play an essential role in addressing global economic, social, and political issues, preventing armed conflicts, and ensuring effective use of regional resources.

This article examines the origin and development stages of international organizations, their classification, the differences between intergovernmental and non-governmental organizations, as well as the role and significance of the United Nations in contemporary international relations. This approach highlights the distinctive characteristics of international organizations as an institution of modern international law.
