This volume explores the nature of civil war in the modern world and in historical perspective. Civil wars represent the principal form of armed conflict since the end of the Second World War, and certainly in the contemporary era. The nature and impact of civil wars suggests that these conflicts reflect and are also a driving force for major societal change. In this sense, Understanding Civil Wars: Continuity and change in intrastate conflict argues that the nature of civil war is not fundamentally changing in nature. The book includes a thorough consideration of patterns and types of intrastate conflict and debates relating to the causes, impact, and ‘changing nature’ of war. A key focus is on the political and social driving forces of such conflict and its societal meanings, significance and consequences. The author also explores methodological and epistemological challenges related to studying and understanding intrastate war. A range of questions and debates are addressed. What is the current knowledge regarding the causes and nature of armed intrastate conflict? Is it possible to produce general, cross-national theories on civil war which have broad explanatory relevance? Is the concept of ‘civil wars’ empirically meaningful in an era of globalization and transnational war? Has intrastate conflict fundamentally changed in nature? Are there historical patterns in different types of intrastate conflict? What are the most interesting methodological trends and debates in the study of armed intrastate conflict? How are narratives about the causes and nature of civil wars constructed around ideas such as ethnic conflict, separatist conflict and resource conflict? This book will be of much interest to students of civil wars, intrastate conflict, security studies and international relations in general.

NEW YORK TIMES BESTSELLER • A leading political scientist examines the dramatic rise in violent extremism around the globe and sounds the alarm on the increasing likelihood of a second civil war in the United States “Required reading for anyone invested in preserving our 246-year experiment in self-government.”—The New York Times Book Review (Editors’ Choice) WINNER OF THE GLOBAL POLICY INSTITUTE AWARD • THE SUNDAY TIMES BOOK OF THE YEAR • ONE OF THE BEST BOOKS OF THE YEAR: Financial Times, The Times (UK), Esquire, Prospect (UK) Political violence rips apart several towns in southwest Texas. A far-right militia plots to kidnap the governor of Michigan and try her for treason. An armed mob of Trump supporters and conspiracy theorists storms the U.S. Capitol. Are these isolated incidents? Or is this the start of something bigger? Barbara F. Walter has spent her career studying civil conflict in places like Iraq, Ukraine, and Sri Lanka, but now she has become increasingly worried about her own country. Perhaps surprisingly, both autocracies and healthy democracies are largely immune from civil war; it’s the countries in the middle ground that are most vulnerable. And this is where more and more countries, including the United States, are finding themselves today. Over the last two decades, the number of active civil wars around the world has almost doubled. Walter reveals the warning signs—where wars tend to start, who initiates them, what triggers them—and why some countries tip over into conflict while others remain stable. Drawing on the latest international research and lessons from over twenty countries, Walter identifies the crucial risk factors, from democratic backsliding to factionalization and the politics of resentment. A civil war today won’t look like America in the 1860s, Russia in the 1920s, or Spain in the 1930s. It will begin with sporadic acts of violence and terror, accelerated by social media. It will sneak up on us and leave us wondering how we could have been so blind. In this urgent and insightful book, Walter redefines civil war for a new age, providing the framework we need to confront the danger we now face—and the knowledge to stop it before it’s too late.
