"This is a first-rate work of political science. Page Fortna does something all too rare in contemporary international relations research. She asks a normatively important question--what factors determine the success or failure of a peace agreement following an interstate war?--and then develops a compelling answer based on a systematic and careful consideration of relevant evidence. Both as an example of research methods and for its substantive conclusions it should be a natural choice for graduate and advanced undergraduate seminars."--James D. Fearon, Stanford University "Addressing an extremely timely and important subject, this book will generate considerable interest from both the academic and policy community. Page Fortna offers a compelling analysis of the duration of peace and of the ability of belligerents and outsiders to affect the risks of a renewed war.Peace Timenot only taught me a lot but also generated several new ideas I would like to pursue. I look forward to assigning it in both my undergraduate and graduate classes."--Suzanne Werner, Emory UniversityFortna, Virginia Page is the author of 'Peace Time Cease-Fire Agreements and the Durability of Peace', published 2004 under ISBN 9780691115122 and ISBN 0691115125.
