This chapter discusses how, since the end of the Cold War, the global security agenda has not only widened but also deepened, moving the focus of security concerns away from the sovereign State to include other objects such as the environment, social groups, and regional institutions. The process of widening and deepening the global security agenda is premised upon the theory of securitization. Since its emergence, this theory has provided a critical perspective to security studies and contemporary debates about security governance. After briefly reviewing the trajectory of the theoretical debate, the chapter examines the institutional practice of securitization, with particular focus on the practices of the United Nations, European Union, African Union, and the Association of Southeast Asian Nations as major international and regional security institutions. The understanding of how global and regional policy issues have been securitized in institutional practices is of particular significance to the development of international law because of the ways in which the process of securitization operates within, or interacts with, the existing framework of international law. The role of national security in the process of securitization of a global policy agenda also reveals normative constraint within the framework of international law.
