Since the development of the modern state system in Europe four centuries ago, there have been ten general wars involving a majority of the major powers and a high level of casualties. Another major war is difficult to conceive of, since it would presumably be the last such conflict, and yet it is not an impossibility. In this volume a distinguished group of political scientists and historians examine the origins of major wars and discuss the problems in preventing a nuclear war.

This widely used and acclaimed text reader brings together some of the best work on the onset of war, the expansion of war, the conditions of peace, and the termination and impact of war. Editorial commentary on the major findings and the statistical analysis used in each study teaches students how to read the article so that they can become literate in social science methods. A learning package in the appendix provides a programmed text to teach students how to interpret tables, read basic statistics, and conduct elementary data analysis. Correlates of War data on European countries is provided, and a methodological table of contents allows instructors to assign articles from the easiest (simple percentages) to the most advanced (time series and formal modeling).

Political psychology applies what is known about human psychology to the study of politics. It examines how people reach political decisions on topics such as voting, party identification, and political attitudes as well as how leaders mediate political conflicts and make foreign policy decisions. In this updated third edition of The Oxford Handbook of Political Psychology, Leonie Huddy, David O. Sears, Jack S. Levy, and Jennifer Jerit have gathered together an international group of distinguished scholars to provide an up-to-date account of key topics and areas of research in the field. Chapter authors draw on theory and research on biopsychology, neuroscience, personality, psychopathology, evolutionary psychology, social psychology, developmental psychology, cognitive psychology, and intergroup relations. Some chapters address the political psychology of political elites, while other chapters deal with the dynamics of mass political behavior. Focusing first on political psychology at the individual level (attitudes, values, decision-making, ideology, personality) and then moving to the collective (group identity, mass mobilization, political violence), this fully interdisciplinary volume covers models of the mass public and political elites and addresses both domestic issues and foreign policy. Now with new chapters on authoritarianism, nationalism, status hierarchies, minority political identities, and several other topics along with substantially updated material to account for the recent cutting-edge research within both psychology and political science, this is an essential reference for scholars and students interested in the intersection of the two fields.

The First World War had profound consequences both for the evolution of the international system and for domestic political systems. How and why did the war start? Offering a unique interdisciplinary perspective, this volume brings together a distinguished group of diplomatic historians and international relations scholars to debate the causes of the war. Organized around several theoretically based questions, it shows how power, alliances, historical rivalries, militarism, nationalism, public opinion, internal politics, and powerful personalities shaped decision-making in each of the major countries in the lead up to war. The emphasis on the interplay of theory and history is a significant contribution to the dialogue between historians and political scientists, and will contribute to a better understanding of the war in both disciplines.

In this far-reaching exploration of the evolution of warfare in human history, Jack S. Levy and William R. Thompson provide insight into the perennial questions of why and how humans fight. Beginning with the origins of warfare among foraging groups, "The Arc of War" draws on a wealth of empirical data to enhance our understanding of how war began and how it has changed over time. The authors point to the complex interaction of political economy, political and military organization, military technology, and the threat environment - all of which create changing incentives for states and other actors. They conclude that those actors that adapt survive, and those that do not are eliminated. In modern times, warfare between major powers has become exceedingly costly and therefore quite rare, while lesser powers are too weak to fight sustained and decisive wars or to prevent internal rebellions. Conceptually innovative and historically sweeping, "The Arc of War" represents a significant contribution to the existing literature on warfare.

Political psychology applies what is known about human psychology to the study of politics. It examines how, for example, people reach political decisions on topics such as voting, party identification, and political attitudes as well as how leaders mediate political conflicts and make foreign policy decisions. The Oxford Handbook of Political Psychology gathers together a distinguished group of scholars from around the world to shed light on such questions as: how does personality affect leadership style? What are the origins of racial prejudice? How does violent communal conflict originate? Focusing first on political psychology at the individual level (attitudes, values, decision-making, ideology, personality) and then moving to the collective (group identity, mass mobilization, political violence), this fully interdisciplinary volume covers models of the mass public and political elites and addresses both domestic issues and foreign policy. Now with new material providing an up-to-date account of cutting-edge research within both psychology and political science, this is an essential reference for scholars and students interested in the intersection of the two fields.

The apparently accelerating arms race between the United States and the Soviet Union and the precarious political conditions existing in many parts of the world have given rise to new anxiety about the possibility of military confrontation between the superpowers. Despite the fateful nature of the risk, we have little knowledge, as Jack S. Levy has pointed out, "of the conditions, processes, and events which might combine to generate such a calamity." No empirically confirmed theory of the causes of war exists, and the hypotheses -- often contradictory -- that have been proposed remain untested. As a step toward the formulation of a theory of the causes of war that can be tested against historical experience, Levy has developed a unique data base that will serve as an invaluable resource for students of international conflict in coming years. War in the Modern Great Power System provides a much-needed perspective on the major wars of the past. In this thorough and systematic study, Levy carefully defines the Great Power concept and identifies the Great Powers and their international wars since the late fifteenth century. The resulting compilation of war data is unique because of its five-century span and its focus on a well-defined set of Great Powers. Turning to a quantitative analysis of the characteristics, patterns, and trends in war, Levy demonstrates that although wars between the Great Powers have become increasingly serious in every respect but duration over the last five hundred years, their frequency has diminished. He rejects the popular view that the twentieth century has been the most warlike on record, and he demonstrates that it instead constitutes a return to the historical norm after the exceptionally peaceful nineteenth century. Applying his data to the question whether war is "contagious," he finds that the likelihood of war is indeed highest when another war is under way, but that this contagious effect disappears after the first war is over. Contrary to the popular "war-weariness" theory, he finds no evidence that war generates an aversion to subsequent war. This study, extending the scientific analysis of war back over five centuries of international history, constitutes a major contribution to our knowledge of international conflict.
