International Relations: Theories, Concepts, and Organizations analyzes the changing dynamics of world politics on a rational scale. It presents the conceptual and theoretical codes of International Relations (IR) to academics, journalists, politicians, and thinkers. In addition to concepts and theories, intergovernmental and non-governmental organizations (NGOs) that have an important place in IR are examined. Under the influence of the globalization process, radical changes are taking place in world politics. Increasingly complex, world politics is transforming into a multi-layered structure. This book has been prepared to make IR understandable and accessible clearly.
