Why This Matters

Every political system you'll encounter in this course—whether you're analyzing democratic transitions, comparing authoritarian regimes, or evaluating policy outcomes—rests on a foundation of core concepts. These aren't abstract definitions to memorize; they're the analytical tools you'll use to explain why governments function the way they do, how power flows through institutions, and what makes political systems stable or prone to collapse.

When exam questions ask you to compare political systems or explain institutional design, you're being tested on your ability to apply these concepts, not just recall them. Understanding legitimacy helps you explain why some authoritarian regimes survive while others fall. Grasping sovereignty lets you analyze tensions between national governments and international organizations. Don't just memorize definitions—know what each concept does in political analysis and which concepts pair together to explain real-world phenomena.


Foundations of Political Authority

Before examining specific systems, you need to understand where political power comes from and what makes it accepted. These concepts explain the basic building blocks of any political order.

Sovereignty

  • Supreme authority over a territory—the foundational claim that a state can govern itself without external interference
  • Essential to statehood alongside defined territory, permanent population, and functioning government; without sovereignty, there is no independent state
  • Increasingly contested by globalization, international organizations, and transnational challenges like climate change and migration

Legitimacy

  • The acceptance of a government's right to rule—distinct from mere power; a government can have power without legitimacy, but not stability
  • Three classical sources identified by Max Weber: legal-rational (laws and procedures), traditional (custom and heredity), and charismatic (personal qualities of leaders)
  • Determines regime durability—illegitimate governments must rely more heavily on coercion, making them vulnerable to collapse

Power

  • The capacity to influence behavior of individuals, groups, or institutions—the currency of all political relationships
  • Multiple sources including authority (legitimate power), coercion (force or threat), and persuasion (changing minds through argument)
  • Shapes all political outcomes—understanding who has power and how they use it is central to political analysis

Compare: Sovereignty vs. Legitimacy—both involve authority, but sovereignty concerns external recognition of a state's independence while legitimacy concerns internal acceptance of a government's right to rule. An FRQ might ask how a regime can have sovereignty but lack legitimacy (think: internationally recognized but domestically contested governments).


Types of Political Systems

Political scientists classify governments based on how power is distributed and who participates in governance. These categories form the basis for comparative analysis.

Democracy

  • Government by the people—power exercised directly or through elected representatives who remain accountable to citizens
  • Core features include free and fair elections, protection of human rights, political equality, and the rule of law
  • Not binary but a spectrum—democracies vary in quality, and political scientists measure democratic consolidation using multiple indicators

Authoritarianism

  • Concentrated power with limited pluralism—a single leader, party, or small group holds authority and restricts political participation
  • Suppression of dissent through censorship, surveillance, and punishment; citizens excluded from meaningful political decision-making
  • Multiple varieties including military juntas, one-party states, personalist dictatorships, and hybrid regimes that maintain democratic facades

Federalism

  • Divided sovereignty between central and regional governments, each with constitutionally protected authority
  • Accommodates diversity by allowing subnational units to address local preferences while maintaining national unity on shared concerns
  • Creates multiple access points for political participation and policy experimentation; states as "laboratories of democracy"

Compare: Democracy vs. Authoritarianism—both require some form of legitimacy to survive, but democracies derive it from procedural consent (elections, participation) while authoritarian regimes often rely on performance legitimacy (economic growth, stability) or traditional/charismatic claims. If an FRQ asks about regime stability, consider which legitimacy source each system depends on.


Institutional Design and Constraints

How governments structure their institutions determines how power flows and what limits exist on its exercise. These concepts explain the architecture of political systems.

Separation of Powers

  • Division of authority among executive, legislative, and judicial branches—each with distinct functions and independent operation
  • Prevents tyranny through checks and balances; no single branch can dominate without resistance from others
  • Varies across systems—presidential systems (U.S.) have stricter separation than parliamentary systems (U.K.) where executive emerges from legislature

Constitutionalism

  • Government limited by fundamental law—authority derives from and must conform to constitutional principles
  • Protects rights by placing certain freedoms beyond the reach of ordinary political majorities
  • Requires enforcement mechanisms—constitutional courts, judicial review, and amendment procedures that make changes difficult

Rule of Law

  • Legal equality and accountability—all individuals and institutions, including government officials, are bound by publicly known laws
  • Prevents arbitrary power by requiring decisions based on established rules rather than personal whim
  • Foundation for rights protection—without rule of law, constitutional guarantees become mere paper promises

Bureaucracy

  • Administrative apparatus of trained officials who implement government policies through established procedures
  • Ensures consistency and expertise—bureaucratic rules create predictability; specialized knowledge shapes policy implementation
  • Can become a political actor—bureaucracies influence outcomes through discretion, information control, and institutional interests

Compare: Separation of Powers vs. Federalism—both divide power to prevent concentration, but separation of powers divides functionally (by branch) while federalism divides territorially (by level of government). The U.S. uses both simultaneously, creating multiple veto points in the policy process.


Political Participation and Representation

These concepts explain how citizens connect to government and how diverse interests get translated into political outcomes.

Political Parties

  • Organized groups seeking power through elections and policy influence—the primary vehicles for political competition in democracies
  • Aggregate and articulate interests by combining diverse voter preferences into coherent platforms and policy programs
  • Structure political choice—party systems (two-party vs. multiparty) shape what options voters have and how coalitions form

Electoral Systems

  • Rules for translating votes into seats—the mechanism determining how citizen preferences become political representation
  • Major types include first-past-the-post (winner-take-all), proportional representation (seats match vote shares), and ranked-choice voting (preference ordering)
  • Profound consequences for party systems, representation of minorities, and government stability; electoral rules shape political behavior

Civil Rights and Liberties

  • Fundamental protections against government overreach—freedoms of speech, religion, assembly, and due process guarantees
  • Distinguish civil liberties (freedoms from government interference) from civil rights (protections of equal treatment)
  • Essential for democracy—without protected space for dissent and participation, democratic competition becomes impossible

Compare: Political Parties vs. Electoral Systems—parties are the actors while electoral systems are the rules of the game. The same parties behave differently under different electoral rules; proportional representation encourages multiple parties while first-past-the-post tends toward two-party dominance (Duverger's Law).


Ideas That Shape Politics

Political behavior isn't random—it's guided by belief systems and collective identities that determine what people want from government.

Ideology

  • Coherent belief systems about how society should be organized and what government should do
  • Major ideologies include liberalism (individual rights, limited government), conservatism (tradition, gradual change), socialism (economic equality, collective ownership), and nationalism (national identity and interests)
  • Shapes political conflict—ideological differences define party competition, policy debates, and social movements

Nation-State

  • Political unit combining nation and state—a government (state) that corresponds to a people with shared identity (nation)
  • The dominant form of political organization since the 19th century; international system assumes nation-state as basic unit
  • Often imperfect fit—multinational states, stateless nations, and contested borders create ongoing political tensions

Compare: Ideology vs. Political Parties—ideologies are the ideas while parties are the organizations that mobilize around them. Multiple parties can share an ideology (various conservative parties) and single parties can contain ideological factions (big-tent parties). Understanding this distinction helps explain intra-party conflict and party system change.
