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

“Like those who spoke up clearly about the dangers of global warming decades ago, Walter delivers a grave message that we ignore at our peril.”—David Remnick, The New Yorker

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 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.

Praise for How Civil Wars Start

“It turns out that there is a discipline that you might call ‘civilwarology’—the study of the factors that lead to civil war. . . . Barbara F. Walter became a civilwarologist nearly a quarter of a century ago and her entry is evidently well-thumbed in the Rolodexes of the CIA and the U.S. State Department. In other words, she knows what she’s talking about—which makes this book rather scary.”—The Times (U.K.)
