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.

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.

When did war begin? Standard military accounts tend to start with the Graeco-Persian wars, laying undue emphasis on the preeminence of Greek heavy infantry. But, as this strikingly original and entertaining book shows, the origins of war can be traced back not to the Iron Age, or even to the Bronze Age, but to the emergence of settled life itself nearly 10,000 years ago. The military revolution that occurred then?the invention of major new weapons, the massive fortifications, the creation of strategy and tactics?ultimately gave rise to the great war machines of ancient Egypt, Assyria, and Persia that dominated the Near East until the time of Alexander the Great.It is Arther Ferrill's thesis that in the period before Alexander there were two independent lines of military development?a Near Eastern one culminating in the expert integration of cavalry, skirmishers, and light infantry and a Greek one based on heavy infantry. When Philip and Alexander blended the two traditions in their crack Macedonian army, the result was a style of warfare that continued, despite technological changes, down to Napoleon.This newly revised edition presents detailed and copiously illustrated accounts of all the major battles on land and sea up to the fourth century b.c., analyzes weapons from the sling to the catapult, and discusses ancient strategy and tactics, making this a book for armchair historians everywhere.

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.

Stretching across continents and centuries, The Origins of War: Violence in Prehistory provides a fascinating examination of executions, torture, ritual sacrifices, and other acts of violence committed in the prehistoric world. Written as an accessible guide to the nature of life in prehistory and to the underpinnings of human violence. Combines symbolic interpretations of archaeological remains with a medical understanding of violent acts. Written by an eminent prehistorian and a respected medical doctor.

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.

The American Civil War (1861-65) was the bloodiest war of the nineteenth century and its impact continues to be felt today. It, and its origins have been studied more intensively than any other period in American history, yet it remains profoundly controversial. Brian Holden Reid's formidable volume is a major contribution to this ongoing historical debate. Based on a wealth of primary research, it examines every aspect of the origins of the conflict and addresses key questions such as was it an avoidable tragedy, or a necessary catharsis for a divided nation? How far was slavery the central issue? Why should the conflict have errupted into violence and why did it not escalate into 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.

A brisk account of this defining feature of human society, from prehistory to nuclear proliferation and lethal autonomous weapons. The Shortest History books deliver thousands of years of history in one riveting, fast-paced read. War has changed, but we have not. From our hunter-gatherer ancestors to the rival nuclear powers of today, whenever resources have been contested, we’ve gone to battle. Acclaimed historian Gwynne Dyer illuminates our many martial clashes in this brisk account, tracing warfare from prehistory to the world’s first cities—and on to the thousand-year “classical age” of combat, which ended when the firearm changed everything. He examines the brief interlude of “limited war” before eighteenth-century revolution ushered in “total war”—and how the devastation was halted by the nuclear shock of Hiroshima. Then came the Cold War and Russia’s invasion of Ukraine, which punctured the longest stretch of peace between major powers since World War II. For all our advanced technology and hyperconnected global society, we find ourselves once again on the brink as climate change heightens competition for resources and superpowers stand ready with atomic bombs, drones, and futuristic “autonomous” weapons in development. Throughout, Dyer delves into anthropology, psychology, and other relevant fields to unmask the drivers of conflict. The Shortest History of War is for anyone who wants to understand the role of war in the human story—and how we can prevent it from defining our future.
