States of Exception in American History brings to light the remarkable number of instances since the Founding in which the protections of the Constitution have been overridden, held in abeyance, or deliberately weakened for certain members of the polity. In the United States, derogations from the rule of law seem to have been a feature of-not a bug in-the constitutional system. The first comprehensive account of the politics of exceptions and emergencies in the history of the United States, this book weaves together historical studies of moments and spaces of exception with conceptual analyses of emergency, the state of exception, sovereignty, and dictatorship. The Civil War, the Great Depression, and the Cold War figure prominently in the essays; so do Francis Lieber, Frederick Douglass, John Dewey, Clinton Rossiter, and others who explored whether it was possible for the United States to survive states of emergency without losing its democratic way. States of Exception combines political theory and the history of political thought with histories of race and political institutions. It is both inspired by and illuminating of the American experience with constitutional rule in the age of terror and Trump.
