As one part of the global democratic recession, severe political polarization is increasingly afflicting old and new democracies alike, producing the erosion of democratic norms and rising societal anger. This volume is the first book-length comparative analysis of this troubling global phenomenon, offering in-depth case studies of countries as wide-ranging and important as Brazil, India, Kenya, Poland, Turkey, and the United States. The case study authors are a diverse group of country and regional experts, each with deep local knowledge and experience.

Democracies Divided identifies and examines the fissures that are dividing societies and the factors bringing polarization to a boil. In nearly every case under study, political entrepreneurs have exploited and exacerbated long-simmering divisions for their own purposes—in the process undermining the prospects for democratic consensus and productive governance.

But this book is not simply a diagnosis of what has gone wrong. Each case study discusses actions that concerned citizens and organizations are taking to counter polarizing forces, whether through reforms to political parties, institutions, or the media.

The book’s editors distill from the case studies a range of possible ways for restoring consensus and defeating polarization in the world’s democracies. Timely, rigorous, and accessible, this book is of compelling interest to civic activists, political actors, scholars, and ordinary citizens in societies beset by increasingly rancorous partisanship.

Advance Praise

“A must-read for anyone concerned about the fate of contemporary democracies. Democracies Divided offers new insights into the causes of polarization, illuminates the ways polarization can harm democracy, and explores a range of real-world efforts to overcome polarization.”
—Steven Levitsky, Harvard University, co-author of How Democracies Die

“At a moment when American society is being divided by profound polarization, Carothers and O’Donohue provide new and necessary perspective by focusing on polarization as an international problem. Their insights will help Americans, Europeans, and citizens around the world identify why polarization is worsening and what can be done to counter it.”
—Anne Applebaum, The Washington Post

“An exceptionally rich, insightful, and timely analysis of one of the most serious challenges to democracy. The lucid and incisive case studies vividly demonstrate the danger posed by intense polarization, and Carothers and O’Donohue urge creative initiatives to bridge political gulfs. This is a must-read for scholars and practitioners of democracy.”
—Larry Diamond, Stanford University, author of Ill Winds

    Notes From Kyiv: Is Ukraine Preparing for Elections?

    As discussions about settlement and elections move from speculation to preparation, Kyiv will have to manage not only the battlefield, but also the terms of political transition. The thaw will not resolve underlying tensions; it will only expose them more clearly.
