'The First World War is a dominant event for subfields in both history and political science. This interdisciplinary revisiting of the causes of the conflict focuses on several enduring and important questions, including the impact of situational and dispositional factors, whether Germany or other states bear primary responsibility, and why the war began in 1914. These serious, scholarly, and timely essays are a valuable addition to multiple research traditions, including international relations theory, security studies, and diplomatic history.' Colin Elman, Maxwell School of Syracuse University 'This important collection of essays offers new perspectives on a century-old controversy that shows no sign of abating. It is a unique volume which advances original and thought-provoking interpretations by leading historians and political scientists.' Annika Mombauer, The Open University 'World War I continues to command attention even after a century both because of the immense destruction it caused and the still worse conflict and war it helped produce. That it also remains highly instructive on fundamental questions of war, peace, and international politics is convincingly proved by this well organized and expertly edited collection of original essays by leading historians and political scientists.' Paul W. Schroeder, Professor (emeritus), University of Illinois at Urbana-Champaign 'The editors are to be congratulated for assembling a closely reasoned volume of essays of outstanding quality. Blending insights from international history and from political science, this book provides an indispensable update that forcefully represents both sides in the continuing debate.' David Stevenson, London School of Economics and Political Science
