How Democracies Die warns that democracy's greatest threats often come from within.
If you're concerned about the health of democracy, this book offers a clear-eyed analysis of how democratic systems can unravel—not just through coups, but through the slow erosion of norms and institutions. Levitsky and Ziblatt draw on global and historical examples to show how even established democracies are vulnerable when key unwritten rules are ignored. Steven Levitsky and Daniel Ziblatt are Harvard political scientists specializing in comparative politics and the study of democratic regimes. Their expertise gives them a broad, global perspective on how democracies succeed and fail.
Levitsky and Ziblatt argue that democracy depends not just on laws and constitutions, but on shared norms—especially mutual tolerance and institutional forbearance. These unwritten rules ensure that rivals see each other as legitimate and that those in power restrain themselves from exploiting legal loopholes. When these norms break down, even robust democracies can slide toward authoritarianism.
The authors identify two core democratic norms: mutual tolerance (accepting political opponents as legitimate) and institutional forbearance (avoiding the use of every possible legal advantage to crush rivals). When politicians and citizens treat opponents as existential threats or exploit every technicality to win, the system becomes brittle and prone to crisis.
Democratic backsliding rarely happens overnight. Levitsky and Ziblatt show that elected leaders can gradually undermine democracy from within—by attacking the press, politicizing institutions, and weakening checks and balances. These actions often occur legally, making them harder to recognize and resist until it’s too late.
Drawing on examples from Europe, Latin America, and the United States, the book demonstrates that no democracy is immune. From the rise of leaders like Hugo Chávez to the collapse of democracies in interwar Europe, the authors illustrate patterns and warning signs that precede democratic breakdowns.
Levitsky and Ziblatt devote special attention to the United States, arguing that its democracy has survived thanks to strong norms—but these are now under strain. They trace the erosion of bipartisanship and the rise of extreme partisanship, warning that the U.S. is not exempt from the dangers faced elsewhere.
The book ends with a call to action: citizens and leaders must actively defend democratic norms, resist the temptation to treat politics as total war, and build broad coalitions to isolate would-be authoritarians. Democracy, they argue, is not self-sustaining; it requires constant vigilance and commitment.
How Democracies Die is a sobering, accessible guide to the warning signs of democratic decline. By focusing on the vital role of norms and the dangers of polarization, Levitsky and Ziblatt offer both a diagnosis and a prescription for anyone who cares about the future of democracy. This book is essential reading for understanding the fragility of democratic systems and the responsibility of citizens to protect them.
“Democracies may die at the hands not of generals but of elected leaders—presidents or prime ministers who subvert the very process that brought them to power.”
“The tragic paradox of the electoral route to authoritarianism is that democracy’s assassins use the very institutions of democracy—gradually, subtly, and even legally—to kill it.”
