What Is Populism: Definitions, Historical Examples, and Political Impact

Defining Populism

Populism is a contested concept in political science, but most contemporary scholars define it through what political scientist Cas Mudde has called a "thin-centred ideology" — a set of loosely connected ideas that can attach to a wide variety of more substantive political programs. In Mudde's influential definition, populism divides society into two homogeneous and antagonistic camps: "the pure people" versus "the corrupt elite," and holds that politics should be an expression of the general will of the people.

Three core elements characterize populism across its many manifestations:

• Anti-elitism: A claim that a corrupt, self-serving elite — economic, political, cultural, or media — has betrayed the people and hijacked government for its own benefit.
• Popular sovereignty: An emphasis on the will of "the people" as the ultimate source of political legitimacy, often invoked to override institutional checks, legal constraints, or minority rights.
• Moral Manichaeism: The world is divided into the virtuous people and the degenerate elite; politics is a moral struggle, not merely a competition between interests.

Because populism is a thin ideology, it can combine with almost any substantive political position — nationalism, socialism, agrarianism, or technocracy — producing the wide variety of populist movements observed historically and today.

Left and Right Populism

Populism manifests across the political spectrum. Left-wing populism typically frames "the elite" in economic terms — financiers, corporations, the wealthy — and champions redistribution and expanded social rights for working people. Right-wing populism more often defines the people in cultural or ethnic terms and frames elites as cultural, media, or cosmopolitan establishments who favor immigrants or minorities over "native" citizens. Some scholars (like Ernesto Laclau) see populism as an inherently left-wing phenomenon; others observe it thriving predominantly on the right in contemporary Europe and the Americas.

Historical Examples

American Populist Party (1890s): One of the earliest major uses of "populism" as a self-designation, the U.S. People's Party of the 1890s emerged from agrarian discontent among farmers squeezed by railroads, banks, and currency deflation. It championed monetary reform, nationalization of railroads, and direct democracy. Its 1892 presidential candidate James Weaver won over 1 million votes and carried several states.

Peronism in Argentina (1945–present): Juan Domingo Perón built a populist movement combining labor rights, economic nationalism, anti-imperialism, and charismatic leadership. Peronism has been a dominant force in Argentine politics for decades and represents one of the longest-lived populist movements in history.

Hugo Chávez and Bolivarian Venezuela (1998–2013): Chávez mobilized Venezuela's poor majority against a wealthy oligarchy and foreign (especially U.S.) interests, using oil revenues for extensive social programs while concentrating power and undermining institutional checks on the executive.

European right-wing populism (2000s–present): Parties including France's Rassemblement National, Italy's Lega and Fratelli d'Italia, Hungary's Fidesz, and Poland's Law and Justice (PiS) have achieved significant electoral successes by combining economic concerns with nativist and anti-immigration positions.

Populism and Democratic Institutions

A central debate in political science concerns populism's relationship to democracy. Populism is "democratic" in the sense that it claims to represent the authentic majority; it is potentially "anti-democratic" in that its majoritarian logic can justify attacks on institutions designed to protect minority rights and constrain majority power — courts, independent media, central banks, electoral commissions.

Scholars Steven Levitsky and Lucan Way have documented how populist leaders in Hungary, Venezuela, Turkey, Bolivia, and elsewhere have used electoral majorities to systematically weaken institutional constraints in ways they term "competitive authoritarianism" — maintaining the form of democratic elections while undermining their substance. In Hungary, Viktor Orbán's government used its parliamentary supermajority to pack courts, control media, redraw electoral districts, and rewrite constitutional rules in ways that entrenched its power.

Other scholars, including Chantal Mouffe, argue that populism can serve a democratic function by re-politicizing issues suppressed by technocratic consensus and re-engaging disaffected citizens. From this perspective, right-wing populism's rise reflects the failure of mainstream parties to represent the genuine economic anxieties of working-class voters left behind by globalization.

Conditions for Populist Success

Research identifies several conditions that tend to favor populist electoral success:

• Economic dislocation: Rising inequality, unemployment, or economic insecurity, particularly when mainstream parties are perceived as indifferent or complicit.
• Elite corruption or scandal: High-profile corruption or dysfunction among established parties creates an "anti-elite" opening.
• Cultural threat perceptions: Rapid demographic change, immigration, or perceived cultural displacement among previously dominant groups.
• Institutional distrust: Low trust in courts, media, parliaments, and other institutions that are targets of populist critique.
• Charismatic leadership: Populism is typically personalist — it centers on a charismatic leader who embodies the authentic people.

Global Spread of Populism

Conclusion

Populism is a persistent feature of democratic politics rather than a temporary aberration. It thrives on genuine grievances about inequality, corruption, and cultural change, but can pose serious risks to the institutional safeguards of liberal democracy. Understanding populism — its ideological core, its historical variations, and the conditions that produce it — is essential for comprehending the most significant political developments of the early twenty-first century.
