This volume, with contributions from well-respected experts on Turkey, examines how well different theories and frameworks in international relations explain various aspects of contemporary Turkish foreign policy (TFP). Exploring the value of both structural (neorealist) and ideational (constructivist) approaches, the book's theory informed case studies on the features of TFP including Neo-Ottomanism; the role of religion; and Turkey's relations with the European Union, the Middle East, Russia, and the United States, provide an analytical perspective on developments that have captured the attention of both academics and policymakers. More importantly, this collection examines the shift in Turkey's foreign policy stance from Western and secular (non-sectarian) to Islamist, Turkist, Neo-Ottomanist and Eurasianist orientations. With Turkey assuming importance across a number of regions and issues, this book will be a great resource for academics, researchers, and advanced students of Middle East Studies, and Politics and International Relations. This book was originally published as a special issue of the journal, Turkish Studies.
