This book explores how 'balkanization' as a discourse underpins the policies of the European Union (EU) and the North Atlantic Treaty Organization (NATO) toward the Western Balkans. It shows how EU and NATO policies have emerged from, and led to, the constant reinvention of the unity of the West through 'balkanizing' the region and illustrates how this dynamic is maintained by and instrumentalized for the political elites. Through a genealogical analysis that stretches from the Balkans Wars to more recent events such as North Macedonia's change of name in 2018, the author shows how Western policies have aimed at recreating the united West on the back of the 'broken' Balkans. The book will appeal to scholars and students of Southeast Europe, International Relations, Political Science, Peace and Conflict Studies and History.
