A brilliant and vitally important history of why states go to war, by the acclaimed, award-winning author of The Peloponnesian War. War has been a fact of life for centuries. By lucidly revealing the common threads that connect the ancient confrontations between Athens and Sparta and between Rome and Carthage with the two calamitous World Wars of the twentieth century, renowned historian Donald Kagan reveals new and surprising insights into the nature of war and peace. Vivid, incisive, and accessible, Kagan's powerful narrative warns against complacency and urgently reminds us of the importance of preparedness in times of peace.

One of the most important questions of human existence is what drives nations to war—especially massive, system-threatening war. Much military history focuses on the who, when, and where of war. In this riveting book, Dale C. Copeland brings attention to bear on why governments make decisions that lead to, sustain, and intensify conflicts.Copeland presents detailed historical narratives of several twentieth-century cases, including World War I, World War II, and the Cold War. He highlights instigating factors that transcend individual personalities, styles of government, geography, and historical context to reveal remarkable consistency across several major wars usually considered dissimilar. The result is a series of challenges to established interpretive positions and provocative new readings of the causes of conflict.Classical realists and neorealists claim that dominant powers initiate war. Hegemonic stability realists believe that wars are most often started by rising states. Copeland offers an approach stronger in explanatory power and predictive capacity than these three brands of realism: he examines not only the power resources but the shifting power differentials of states. He specifies more precisely the conditions under which state decline leads to conflict, drawing empirical support from the critical cases of the twentieth century as well as major wars spanning from ancient Greece to the Napoleonic Wars.

In The Behavioral Origins of War, D. Scott Bennett and Allan C. Stam analyze systemic, binary, and individual factors in order to evaluate a wide variety of theories about the origins of war. Challenging the view that theories of war are nothing more than competing explanations for observed behavior, this expansive study incorporates variables from multiple theories and thus accounts for war's multiplicity of causes. While individual theories offer partial explanations for international conflict, only a valid set of theories can provide a complete explanation. Bennett and Stam's unconventional yet methodical approach opens the way for cumulative scientific progress in international relations. D. Scott Bennett is Professor of Political Science at the Pennsylvania State University. Allan C. Stam is Associate Professor in the Government Department at Dartmouth College.

James Joll's study is not simply another narrative, retracing the powder trail that was finally ignited at Sarajevo. It is an ambitious and wide-ranging analysis of the historical forces at work in the Europe of 1914, and the very different ways in which historians have subsequently attempted to understand them. The importance of the theme, the breadth and sympathy of James Joll's scholarship, and the clarity of his exposition, have all contributed to the spectacular success of the book since its first appearance in 1984. Revised by Gordon Martel, this new 3rd edition accommodates recent research and an expanded further reading section.

The Crimean War (1853-56) between Russia, Turkey, Britain, France and the Kingdom of Sardinia was a diplomatically preventable conflict for influence over an unstable Near and Middle East. It could have broken out in any decade between Napoleon and Wilhelm II; equally, it need never have occurred. In this masterly study, based on massive archival research, David Goldfrank argues that the European diplomatic roots of the war stretch far beyond the `Eastern Question' itself, and shows how the domestic concerns of the participants contributed to the outbreak of hostilities.

PMH Bell's famous book is a comprehensive study of the period and debates surrounding the European origins of the Second World War. He approaches the subject from three different angles: describing the various explanations that have been offered for the war and the historiographical debates that have arisen from them, analysing the ideological, economic and strategic forces at work in Europe during the 1930s, and tracing the course of events from peace in 1932, via the initial outbreak of hostilities in 1939, through to the climactic German attack on the Soviet Union in 1941 which marked the descent into general conflict. Written in a lucid, accessible style, this is an indispensable guide to the complex origins of the Second World War.

BANCROFF PRIZE WINNER • King Philip's War, the excruciating racial war—colonists against Indigenous peoples—that erupted in New England in 1675, was, in proportion to population, the bloodiest in American history. Some even argued that the massacres and outrages on both sides were too horrific to "deserve the name of a war." The war's brutality compelled the colonists to defend themselves against accusations that they had become savages. But Jill Lepore makes clear that it was after the war—and because of it—that the boundaries between cultures, hitherto blurred, turned into rigid ones. King Philip's War became one of the most written-about wars in our history, and Lepore argues that the words strengthened and hardened feelings that, in turn, strengthened and hardened the enmity between Indigenous peoples and Anglos. Telling the story of what may have been the bitterest of American conflicts, and its reverberations over the centuries, Lepore has enabled us to see how the ways in which we remember past events are as important in their effect on our history as were the events themselves.
