Democracy
The system that spread and is now contested
Description
In 1974, roughly thirty countries could be classified as democracies. By 2005, the figure had risen to roughly a hundred and twenty. This was one of the most striking political transformations of the twentieth century — what Samuel Huntington, in a 1991 book, called the third wave of democratization. Portugal in 1974, Spain in 1975, the Latin American transitions of the 1980s, the Eastern European collapse in 1989, the post-apartheid transition in 1994, the Arab Spring in 2011 — the period from the mid-1970s to the early 2010s saw authoritarian regimes fall and democratic institutions emerge across most of the world at a pace with no historical precedent. For much of this period, the question was not whether democracy would spread but how quickly.
The trajectory has since reversed. The 2010s and 2020s have seen what Freedom House classifies as a sustained democratic recession — eighteen consecutive years, through 2024, of more countries moving toward authoritarianism than toward democracy. Hungary under Orbán, Turkey under Erdogan, democratic backsliding in several Latin American countries, Poland and India, continued authoritarian consolidation in Russia and China, and stress on American democratic institutions during the Trump years have all contributed to a picture very different from the triumphalist moment of 1990. The third wave has crested. Whether a fourth wave is coming, or whether the democratic share of world states will continue to decline, is one of the major open questions of the current period.
What democracy actually is, whether it is the system most compatible with human flourishing, and whether the specific forms that emerged in the twentieth century are the best available designs are all questions the current moment has reopened. The post-Cold War consensus that treated liberal democracy as the terminal stable form has not survived the past fifteen years. The critiques are coming from several directions — authoritarian, populist, technocratic — and the defenders of democratic institutions are responding from positions that have had to become more self-conscious than a generation ago. Whether the defenses will hold is not yet clear.
● The question we're asking: what is democracy, why did it spread, and why is it now contested?
● What we'll see: the historical trajectory, the institutional forms democracy has taken, the arguments for and against it, and the current stresses on the democratic model.

01The historical trajectory
Democracy in the classical sense originated in Athens in the sixth and fifth centuries BC, as direct rule by the adult male citizens of a small city-state. The Athenian version had roughly thirty to forty thousand enfranchised citizens excluding women, slaves, and resident foreigners. The assembly met regularly, magistrates were selected by lot rather than election, and the system functioned for roughly two centuries before being overtaken by Macedonian and Roman power. Athens was the exception in the ancient Mediterranean; most ancient states were monarchies or oligarchies. The Athenian experiment did not produce a durable tradition, and the word democracy was out of serious political circulation for most of the two millennia after its fall.
The modern democratic tradition begins with the English, American, and French Revolutions of the seventeenth and eighteenth centuries. These did not immediately produce democracy in the contemporary sense. The American Republic of 1787 extended the franchise to roughly twenty percent of adult white men, excluded women, and maintained slavery for another seventy-eight years. The British reforms of 1832 extended the vote to one in five adult men. The French revolutionary democracies were repeatedly overthrown by Bonapartist or Bourbon restorations. What the period produced was the idea and institutional precedents, not democracy as currently understood.
02The institutional forms
Modern democracy in practice is a bundle of institutions rather than a single technique. The standardized components include universal adult suffrage, competitive elections, protected civil liberties, independent judiciary, constitutional limits on executive authority, rule of law, press freedom, and minority rights. When the combination functions, power transitions peacefully through elections, disagreements are resolved through compromise, and citizens have protection from arbitrary state action. Functional democracy is a set of arrangements that together constrain the exercise of power.
The specific institutional forms vary substantially. Parliamentary systems are more common globally than presidential systems. Federal systems distribute power between national and subnational governments; unitary systems do not. Electoral systems vary from proportional representation to single-member district plurality to hybrid forms, each with different consequences. The variation suggests there is no single correct design. What functional democracies have in common is not the specific form but the underlying commitment to competitive politics under rule of law.
03The arguments for and against
The classical case for democracy rests on several claims. The consent argument — legitimate authority must derive from the consent of the governed. The information argument — distributed decision-making aggregates information better than concentrated decision-making by a small elite. The protection argument — democracies are less likely to commit the specific pathologies, including mass atrocities, that authoritarian regimes reliably produce. The peaceful-transition argument — democracy provides the mechanism for changing rulers without violence. Each has defenders and critics; together they provide the core case for democracy as a political system.
The empirical case generally supports the democratic side. Democracies, on average, have higher per-capita GDP, higher life expectancy, better public health outcomes, and lower rates of interstate war with other democracies than authoritarian regimes of equivalent resource endowment. The democratic peace thesis has substantial statistical support. Amartya Sen's argument that democracies do not have large-scale famines has held up relatively well. The weight of the evidence is that democracies, on the outcomes measurable across regime types, tend to do somewhat better than authoritarian regimes.
04The current stresses
The contemporary stresses come from several reinforcing sources. Economic inequality has risen substantially since the 1980s, producing political coalitions that are harder to manage and voter frustrations that populists have exploited. Social media has transformed the information environment in ways that reward outrage and polarization over substantive deliberation. Immigration has become politically toxic across most receiving countries, producing coalitions organized around cultural grievance that strain the liberal-democratic tolerance the postwar order depended on. Aging populations and declining birth rates are changing the electoral balance in ways that are consequential.
The backsliding pattern has been documented extensively. Steven Levitsky and Daniel Ziblatt's 2018 book How Democracies Die, drawing on cases from Latin America and Europe, argued that contemporary decline occurs not through coups but through gradual subversion by elected leaders who dismantle constraints on their power. The pattern — packing courts, weakening press freedom, criminalizing opposition, redrawing electoral districts, restricting civil society — has been visible across multiple countries. That it is recognizable does not make it easy to counter; institutional defenses against gradual subversion are weaker than against outright coups, and by the time cumulative damage is obvious, repair has usually become difficult.
05Conclusion
Democracy still matters because most of the institutional gains that made the modern world tolerable were produced by democratic systems. The reduction of mass poverty, expansion of civil rights, restraint of arbitrary state violence, development of social welfare, protection of minorities, extension of political participation — all have happened, with exceptions, in countries with functioning democratic institutions. Authoritarian regimes have, on the whole, not produced comparable gains and have often produced the specific catastrophes democratic systems were designed to prevent. The case for democracy rests not on philosophical elegance but on an empirical record substantially better than the alternatives on the outcomes most people care about.
