This handbook assesses and discusses the topic of international security, paying attention both to great powers, and smaller actors. In addition to traditional security topics, it also covers topics on international law, international organisations, globalisation, and transnational challenges. Consisting of 62 chapters, the handbook is divided into four parts: (1) Complexity of International Security; (2) Material Geographies and Contemporary Conflicts, which examines the tangible dimensions of security, including territorial disputes, resource distribution, and ongoing conflicts; (3) Immaterial or Diffuse Geographies, focusing on energy, data, cyberspace, digital technologies, and artificial intelligence; and (4) International Security Perspectives on Governance and International Law. As such, the handbook brings together multiple aspects of international security, combining theories and case studies. While continuing to track the development of the new and diverse security concepts, it also considers the latest relevant international events or other important topics, such as energy security, maritime security, decarbonisation of global economy, armed conflict, populism, Ukraine War, Artificial Intelligence, Lethal Autonomous Weapons Systems (LAWS), Arctic, and Feminist Movements.
