This book delves into Turkey’s increasing ethno-religious, pragmatic, and complicated involvement and activism in the Balkans since 2002, under the Justice and Development Party (Adalet ve Kalkınma Partisi – AKP). It primarily focusses on the intersectionality between domestic and foreign policy that has played an important role in Turkey’s recent relations with the Balkan countries as well as exploring how the Europeanisation process influences this relationality. Broadly, the chapters in this volume posit that religion, ethnicity and kin politics are indispensable components of identity politics and have the capacity to transform Turkey’s foreign policy attitudes as well as the orientations of the Balkan countries. The book also asserts that the impact of the processes of Europeanisation and de-Europeanisation on the relationship between Turkey and the Balkans needs to be included into the analysis. This book will be useful to students, researchers and academics interested in Politics, International Relations and Southeast European Studies. The chapters in this book were originally published as a special issue of Southeast European and Black Sea Studies.
