Political science is the systematic study of governments, political processes, and political behavior. It examines how power is distributed and exercised within societies, how political institutions are structured and function, and how individuals and groups engage in political activity. The discipline encompasses the analysis of political systems ranging from direct democracies and constitutional republics to authoritarian regimes and totalitarian states, seeking to understand the principles, mechanisms, and consequences of each.
Governance and political theory form the intellectual backbone of political science. From the classical works of Plato and Aristotle to Enlightenment thinkers like Locke, Montesquieu, and Rousseau, and modern theorists such as Rawls and Habermas, the field grapples with enduring questions about justice, liberty, equality, and the legitimate use of power. Concepts like the social contract, separation of powers, federalism, and constitutionalism provide frameworks for understanding how governments derive authority, how they are constrained, and how citizens relate to the state.
International relations constitutes a major subfield that analyzes interactions among nation-states, international organizations, and non-state actors. Political science also encompasses comparative politics, which examines different political systems across countries, and public policy analysis, which evaluates how governments address societal problems. In an era of globalization, democratic backsliding, and rapid technological change, political science offers essential tools for understanding the forces that shape collective decision-making and the distribution of resources and rights within and among societies.

A system of government in which power is vested in the people, who exercise it directly or through freely elected representatives. Democracies are characterized by free and fair elections, the protection of individual rights, the rule of law, and political pluralism.
Example: The United States operates as a representative democracy where citizens elect members of Congress and the President, who then govern on their behalf within constitutional constraints.
A form of government characterized by the concentration of power in a single leader or a small elite not constitutionally accountable to the people. Authoritarian regimes limit political freedoms, suppress opposition, and control or heavily influence media and civil society.
Example: North Korea under the Kim dynasty exemplifies an authoritarian regime where political dissent is criminalized, the state controls all media, and power is concentrated in a single ruling family.
A governance model in which governmental authority is divided among distinct branches, typically the legislative, executive, and judicial, to prevent the concentration of power and provide checks and balances. Each branch has independent powers and responsibilities that limit the others.
Example: In the United States, Congress makes laws, the President enforces them, and the Supreme Court interprets them, with each branch able to check the others through vetoes, judicial review, and legislative override.
A system of government in which sovereignty is constitutionally divided between a central authority and subnational political units such as states or provinces. Each level of government has its own defined powers and areas of jurisdiction, though they often share responsibilities.
Example: In Germany, the federal government handles defense and foreign policy, while the Laender (states) retain authority over education and policing, with both levels sharing responsibility for taxation.
A coherent set of beliefs about the proper order of society, the role of government, and the relationship between the individual and the state. Ideologies provide frameworks for understanding political events and guide policy preferences and political action.
Example: Liberalism emphasizes individual rights, limited government intervention, and free markets, while socialism advocates for collective ownership and greater economic equality through state regulation or planning.
The aggregate of individual attitudes, beliefs, and preferences held by the adult population on matters of public interest. Public opinion is shaped by media, political socialization, personal experience, and elite discourse, and it influences government policy and electoral outcomes.
Example: Public opinion polling before elections helps campaigns understand voter priorities, while shifts in public sentiment on issues like healthcare or immigration can pressure legislators to change policy positions.
The set of rules and procedures by which votes are translated into seats in a legislature or into executive office. Different systems, such as first-past-the-post, proportional representation, and ranked-choice voting, produce different outcomes in terms of representation and party systems.
Example: The United Kingdom uses first-past-the-post, which tends to produce two dominant parties, while the Netherlands uses proportional representation, which results in a multiparty parliament requiring coalition governments.
The study of interactions among sovereign states, international organizations, multinational corporations, and non-governmental actors. Major theoretical frameworks include realism, which emphasizes power and national interest, and liberalism, which stresses cooperation and international institutions.
Example: The United Nations Security Council represents an institutional approach to international relations, where major powers attempt to maintain global security through collective decision-making, though veto power reflects realist concerns about sovereignty.
