The phenomenon of international security is one of the most controversial areas in terms of social sciences for the last 20 years. However, there is still no consensus in the literature on the meaning of the word ‘security’, which is the origin of the concept. For this reason, this book has tried to reveal the etymological and conceptual dimensions of the subject as clearly as possible and has been successful. This book will be accepted as the most detailed book written for readers who want to see the ‘whole picture’ in the field of security studies. Because in the book, concepts, theories, organizations, facts, and events related to international security are examined in detail.
