What Is The History of Political Science?

The history of political science is the story of how humans went from asking “who should rule?” to building an entire academic discipline around studying how power actually works. It’s a journey from ancient philosophical speculation to modern data-driven research — with some genuinely ruthless thinkers along the way.

Political science as a formal discipline is surprisingly young. The first university departments didn’t appear until the 1880s. But people have been thinking systematically about government, authority, and justice for about 2,500 years.

The Greeks Started Arguing About It First

The ancient Greeks invented democracy. They also invented the habit of arguing about whether democracy was a good idea. Both contributions turned out to be pretty important.

Before the Greeks, political authority was mostly justified by religion or tradition. The pharaoh ruled because the gods said so. Kings were kings because their fathers were kings. Nobody asked whether the system itself was optimal.

The Greek city-states — particularly Athens — changed that. When you have citizens voting in assemblies, debating policy, and occasionally exiling leaders they don’t like, people inevitably start asking harder questions. What’s the best form of government? What makes a law legitimate? Who deserves to participate?

Plato (428–348 BCE) addressed these questions in the Republic, one of the first major works of political philosophy. His answer was pretty unflattering to democracy. Plato argued that most people are too ignorant or easily manipulated to govern well. The ideal state should be ruled by “philosopher-kings” — people who’ve spent decades studying truth and goodness. Democracy, he thought, degenerates into mob rule and eventually tyranny.

Aristotle (384–322 BCE) took a more empirical approach. He and his students collected and analyzed the constitutions of 158 Greek city-states — essentially the first comparative politics study. He classified governments into six types: monarchy, aristocracy, and polity (the good versions) versus tyranny, oligarchy, and democracy (the corrupt versions). His analysis was practical rather than utopian. The best achievable government, Aristotle thought, was a polity — a stable middle-class constitutional system.

Aristotle’s Politics raised questions that political scientists still wrestle with: What causes revolutions? How do economic conditions affect political stability? What institutional arrangements best prevent corruption?

Rome: Law, Republic, and Empire

The Romans were better administrators than philosophers, but their contributions to political thinking were substantial.

Cicero (106–43 BCE) adapted Greek political philosophy for Roman circumstances. He developed the concept of natural law — the idea that there are universal moral principles discoverable by reason, independent of any particular government’s decrees. This concept survived the fall of Rome and eventually influenced the American Declaration of Independence’s claim that certain rights are “self-evident.”

The Roman Republic’s constitutional structure — with its separation of powers among consuls, the Senate, and popular assemblies — provided a model that later political thinkers studied intensely. Polybius (c. 200–118 BCE) analyzed Rome’s “mixed constitution” as a balance of monarchical, aristocratic, and democratic elements, arguing that this balance explained Rome’s success.

The Republic’s collapse into Empire raised uncomfortable questions about whether republics are inherently unstable. These questions haunted political thinkers for centuries — especially the American founders, who were obsessed with the Roman example.

Medieval Political Thought: God and Government

Medieval political thinking in Europe was dominated by one question: what is the proper relationship between spiritual authority (the Church) and temporal authority (kings and emperors)?

Augustine of Hippo (354–430 CE) argued in The City of God that earthly political arrangements are inherently imperfect and secondary to the spiritual city of God. Government exists to restrain sin, not to achieve perfection. This was a pretty pessimistic view, and it shaped Christian political thought for a millennium.

Thomas Aquinas (1225–1274) was more optimistic. Drawing on Aristotle (who had been reintroduced to Europe through Islamic scholars), Aquinas argued that government is natural and good — humans are social animals who need political community to flourish. He also developed the concept of just war, specifying conditions under which warfare is morally permissible.

The Investiture Controversy (11th–12th centuries) — a showdown between popes and Holy Roman Emperors over who got to appoint bishops — forced the development of more sophisticated theories about the limits of authority. This was practical political theory driven by real institutional conflict.

In the Islamic world, Al-Farabi (c. 872–950) described the ideal city ruled by a philosopher-prophet, while Ibn Khaldun (1332–1406) took a radically different approach. His Muqaddimah analyzed the rise and fall of civilizations through what we’d now call sociological methods — looking at group solidarity (asabiyyah), economic conditions, and institutional decay. Ibn Khaldun is sometimes called the first social scientist, and his work reads as surprisingly modern.

Machiavelli: The Ruthless Turn

Niccolo Machiavelli (1469–1527) broke decisively from the tradition of imagining ideal states. He wanted to describe how politics actually works.

The Prince (1513) is infamous for advising rulers that “it is better to be feared than loved.” But the real significance isn’t the cynicism — it’s the method. Machiavelli analyzed power relationships empirically, drawing on historical examples rather than moral ideals. He separated the study of politics from ethics and theology.

Was he a monster or a realist? Scholars have argued about this for 500 years. His Discourses on Livy show a genuine commitment to republican government. Some read The Prince as satire, others as straightforward advice, others as a job application to the Medici family. Whatever his intention, Machiavelli established that you could study politics without assuming rulers are virtuous.

Social Contract Theory: Why Government Exists

The 17th and 18th centuries produced the idea that government’s legitimacy comes from the consent of the governed — the social contract.

Thomas Hobbes (1588–1679), writing during the English Civil War, argued that without government, human life is “solitary, poor, nasty, brutish, and short.” People agree to surrender their freedom to a sovereign in exchange for security. The sovereign’s power should be essentially absolute — any alternative is worse than tyranny.

John Locke (1632–1704) took a much more optimistic view. People have natural rights to life, liberty, and property. Government exists to protect these rights, and if it fails, the people have the right to revolt. Locke’s ideas showed up almost verbatim in the American Declaration of Independence.

Jean-Jacques Rousseau (1712–1778) added another dimension. In The Social Contract (1762), he argued that legitimate government expresses the “general will” of the people. His ideas influenced the French Revolution — for better and worse, since the “general will” can be interpreted in frighteningly authoritarian ways.

Montesquieu (1689–1755) contributed the most practical idea: separation of powers. In The Spirit of the Laws, he argued that liberty requires legislative, executive, and judicial power to be held by different bodies. The American founders read Montesquieu very carefully.

The Birth of Modern Political Science

The 19th century saw political study transform from philosophical speculation into something resembling a social science.

Alexis de Tocqueville (1805–1859) visited America and produced Democracy in America (1835/1840) — still one of the most perceptive analyses of democratic society ever written. He identified both democracy’s strengths (equality, civic participation) and its dangers (tyranny of the majority, individualism leading to apathy).

Karl Marx (1818–1883) argued that political institutions are superstructures built on economic foundations. Understanding politics requires understanding class relations and economic production. Whether you agree with his conclusions, his insistence on connecting political analysis to material conditions permanently changed the field.

The formal discipline of political science emerged in the late 1800s. Francis Lieber held the first chair in political science at Columbia College in 1857. The first dedicated department was established at Columbia in 1880 by John Burgess. The American Political Science Association was founded in 1903.

The 20th Century: Data, Behavior, and Institutions

Political science in the 1900s went through several major phases.

The behavioral revolution (1950s–1960s) pushed the discipline toward quantitative methods. Instead of analyzing constitutions and philosophical texts, political scientists started conducting surveys, running statistical analyses, and testing hypotheses about voter behavior, legislative bargaining, and international conflict. The idea was to make political science as rigorous as the natural sciences.

The rational choice approach applied economic models to politics. Politicians are vote-maximizers. Bureaucrats are budget-maximizers. Voters calculate costs and benefits. This framework generated precise, testable predictions — though critics argued it was too simplistic about human motivation.

The new institutionalism (from the 1980s onward) brought renewed attention to how institutional rules and structures shape political outcomes. Same voters, same politicians, different electoral system — different results. Institutions matter, often more than individual preferences.

Today, political science uses experiments, big data, game theory, computational modeling, and field research alongside traditional methods. The discipline studies everything from congressional voting patterns to civil wars to the effects of social media on democratic participation.

Where the Discipline Stands Now

Modern political science is divided into several subfields: comparative politics, international relations, political theory, American politics (in U.S. departments), and public policy/administration.

The field faces genuine tensions. Between quantitative and qualitative methods. Between the desire for scientific rigor and the reality that political questions are often normative. Between relevance (advising policymakers) and objectivity (studying politics without taking sides).

And the big questions — the ones Plato and Aristotle started with — remain stubbornly open. What makes a government legitimate? Why do democracies sometimes fail? How should we balance liberty and equality? Twenty-five centuries of thinking haven’t produced settled answers. But the questions keep getting sharper, the methods keep improving, and the stakes — given the fragility of democratic institutions worldwide — have never been higher.

Frequently Asked Questions

When did political science become a separate academic discipline?

Political science became a distinct academic discipline in the late 19th century. The first political science department in the United States was established at Columbia University in 1880. The American Political Science Association was founded in 1903. Before this, the study of politics was part of philosophy, history, and law rather than a standalone field with its own methods.

What is the difference between political science and political philosophy?

Political philosophy asks normative questions — how should government work, what is justice, what rights do people have? Political science asks empirical questions — how does government actually work, what predicts voter behavior, what causes revolutions? In practice they overlap, but modern political science emphasizes data, methodology, and testable hypotheses, while political philosophy emphasizes argument and ethical reasoning.

Who is considered the father of political science?

This depends on what you mean. Aristotle is often called the father of political science for his systematic, empirical study of different constitutions and government types. Niccolo Machiavelli is sometimes given the title for separating political analysis from moral idealism. In the modern academic sense, scholars like Francis Lieber and John Burgess, who established the first university departments in the 1800s, founded the discipline as we know it.
