You'll learn the four key indicators of democratic backsliding and strategies for strengthening democratic resilience.
Key idea 1
Authoritarians typically reject democratic rules, deny opponents' legitimacy, tolerate violence, and curtail civil liberties.
Levitsky and Ziblatt identify four behavioral indicators that distinguish authoritarian leaders from conventional politicians. These include rejecting democratic rules, denying political opponents' legitimacy, encouraging or tolerating violence, and showing readiness to curtail civil liberties. The authors demonstrate how these patterns have emerged in countries like Venezuela, Hungary, and Turkey, and how they manifested during Donald Trump's presidency.

Key idea 2
Democracies depend on unwritten norms—mutual toleration and institutional forbearance—more than written constitutions.
The book argues that democracies rely on two key unwritten norms: mutual toleration (accepting political opponents as legitimate) and institutional forbearance (avoiding technically legal but norm-violating actions). These guardrails prevent democratic competition from becoming existential warfare. The authors show how the erosion of these norms in American politics created conditions for democratic backsliding.

Key idea 3
The book examines democratic erosion in Venezuela, Russia, Turkey, Hungary, and Poland to identify common patterns.
Levitsky and Ziblatt analyze how democracies have collapsed in different contexts, showing that the process typically involves elected leaders gradually accumulating power while weakening checks and balances. They demonstrate how constitutional hardball tactics—like court-packing, gerrymandering, and stonewalling nominations—can hollow out democratic institutions while maintaining a veneer of legality.
Remember
How Democracies Die is a comparative political analysis that examines how democracies collapse from within rather than through external invasion. Harvard political scientists Steven Levitsky and Daniel Ziblatt draw on their expertise in authoritarian regimes to identify the warning signs of democratic backsliding and explain how elected leaders can systematically dismantle democratic institutions.
The book contrasts traditional military coups with the modern pattern of democratic erosion, where leaders use democratic processes to gain power before subverting democratic norms. It provides a framework for understanding contemporary threats to democracy in the United States and other established democracies, emphasizing the crucial role of political norms and institutional guardrails.

Levitsky and Ziblatt's analysis combines academic rigor with urgent contemporary relevance. Their framework for identifying authoritarian behavior provides readers with practical tools for assessing political leaders and understanding democratic vulnerabilities. The comparative approach—drawing lessons from Venezuela, Hungary, Turkey, and other cases—makes the book's warnings about American democracy particularly compelling.
Critical Reception: How Democracies Die became a #1 New York Times bestseller and was praised by Barack Obama as "an essential guide to what's happening in American politics." The Economist called it "the most important book of the Trump era," while The Guardian described it as "a fascinating—and alarming—account of how the US shook off its democratic safeguards." The book has been translated into more than 20 languages and remains a foundational text in contemporary political discourse.

Steven Levitsky and Daniel Ziblatt are Harvard University professors of government who specialize in comparative politics and the study of democracy and authoritarianism. Levitsky's research focuses on political parties, authoritarian regimes, and democratization in Latin America and post-communist Europe. Ziblatt specializes in European politics, state-building, and democratic institutions.
Both authors bring decades of academic expertise to their analysis of democratic breakdown. They published a 2023 sequel, Tyranny of the Minority, that addresses counter-majoritarian threats to democracy. Their work has been featured in major media outlets and has influenced political discourse about democratic resilience worldwide.
