"Costly Democracy is a welcome addition to the literature on peace-building. It advances a new and important theory and develops a framework of analysis for understanding the peace-building process that has significant implications for both scholarship and public policy. It is methodologically rigorous—a model of structured comparative case study analysis—and is written with admirable clarity. It is an outstanding book that deserves to be read widely."—Richard Caplan, Cambridge Review of International Affairs "This excellent volume presents two well-supported arguments about the study of peace building and democratization . . . Highly recommended."—M. Tetreault, Choice "A consistent and rigorous focus across many different cases of international peacebuilding makes this a standout book."—Benjamin Reilly, Australian National University "Costly Democracy gets at the heart of today's peace and security agenda: How can societies wracked by war progress toward sustainable peace? In this compellingly written and artfully researched volume, Christoph Zürcher and his colleagues explore the partial and deeply vexatious nature of international support for democratic transitions after war. The detailed and deep case studies evidently expose the outer limits of outsiders' ability to use aid and assistance to promote democracy in societies emerging from conflict."—Timothy D. Sisk, University of Denver "This book advances a new and important claim about democratic peacebuilding—it depends on the politics within fragile states. Sophisticated analysis of nine cases shows that the interactions between internal and external actors and their impact domestic politics is the key. This is a model for collaborative research and sophisticated social science."—Deborah Avant, Editor of Who Governs the Globe?
