In particular, the concept of a risk society, which is the return of the modern era, is also a fact of today's society. In the face of risk society, nation-states are no longer singular individuals. In this context, nation-states should be able to eliminate risks that may arise in mutual coordination. Integration theories that can be applied on a regional and global scale have been created by various researchers throughout history for this situation. One of these approaches, functionalism, was created by David Mitrany in the Post-World War II period. Mitrany proposes that with this approach, called functionalism, an international security environment can be achieved based on the idea of intergovernmental functional organizations specializing in this field. The aim of this study was to explain the concept of functionalism identified with Mitrany and the concepts of risk society identified with Ulrich Beck and to address their relationship with each other. In this context, both concepts are explained in detail in the first two parts of the study. In the third part of the study, the Covid-19 epidemic in which the world is already located is presented as an example of the risk society, and the World Health Organization (WHO) is an intergovernmental organization, as an example of a functionalism approach. The relationship between the Covid-19 outbreak and the WHO samples and the two approaches to each other is the main focus of the study. During the study, a detailed literature review was conducted and related concepts were explained, and descriptive research technique was selected as the main method. As a result of the study, it was found that the ability of nation-states to ensure their national security in the face of potential risks that may arise ceases to be a situation that can be done alone. Nation-states must now interact with each other and ensure international and national security in common coordination. As a result, national security and international security are integrated in the risk society.
