This volume examines how European institutions, the European Union in particular through its policy of conditionality, have shaped the post-conflict reconstruction of the Western Balkans. From state-building to democratization and environmental policies, this book explores whether and in what ways the EU has been successful in consolidating states and democracy in the Balkans. In addition to requiring countries to be ready to join the European Union, the EU has also set new conditions in an effort to become the prime international organization involved in stabilizing the Western Balkans after the wars of the 1990s. Its record has been mixed: the conditions of the EU have often been haphazard and were frequently not followed through. In addition, enlargement towards the Western Balkans has been slow and marred by open questions over the stability of some countries in the region.This volume assesses the EU's struggle to transform the societies through conditionality and whether the offer of EU membership is enough to build stable democracies.This book was published as a special issue of Europe-Asia Studies.
