Europe Undivided explores how the leverage of an enlarging EU has facilitated a convergence toward liberal democracy among credible future members of the EU in Central and Eastern Europe. It reveals how variations in domestic competition put democratizing states on different political trajectories after 1989, and illuminates the changing dynamics of the relationship between the EU and candidate states from 1989 to accession, and beyond. Albeit not by design, the most powerful and successful tool of EU foreign policy has turned out to be EU enlargement--and this book helps us to understand why, and how, it works. `Europe Undivided is an exemplary work of the new comparative-international politics. It is a subtle and substantial analysis of how asymmetric interdependence and meritocratic European Union membership criteria combined to enhance the influence of the EU on domestic political reforms in Eastern Europe.' Robert O. Keohane, Professor of International Affairs, Woodrow Wilson School of International and Public Affairs, Princeton University `In this important study, Vachudova develops an original and compelling analysis of how variations in domestic competition and changes in EU leverage combined to shape postcommunist political and economic pathways in East Central Europe.' Valerie Bunce, Professor and Chair of Government, Aaron Binenkorb Chair of International Studies, Cornell University `A scrupulous, clearly organized, and highly informative analysis of one of the great success stories of our time. Vachudova combines the methods of comparative politics and international relations to explore the very direct connections between political change in Central and Eastern Europe and the influence of the European Union over the fifteen years from the velvet revolutions of 1989 to the eastward enlargement of the EU in 2004.' Timothy Garton Ash, Professor of European Studies, University of Oxford, and Senior Fellow, Hoover Institution, Stanford University Challenges the EU to continue using enlargement as a tool to promote liberal democracy, ethnic tolerance, and economic prosperity.
