Inside This Unit: The Full Breakdown
This unit establishes the core vocabulary of comparison: states, nations, regimes, and governments, and how regimes range from democratic to authoritarian. It introduces sovereignty, legitimacy, and the six course countries (China, Iran, Mexico, Nigeria, Russia, UK).
Why it matters
Unit 1 carries the heaviest MCQ weight (18%–27%) and supplies the conceptual frame for every later unit. Misusing "state," "regime," and "government" is the most common way students lose easy points.
Key concepts
- A state has sovereignty over territory; a regime is the set of rules; a government is the current officeholders.
- Regimes range from liberal democracies to illiberal/hybrid regimes to authoritarian regimes and theocracies.
- Legitimacy (traditional, charismatic, rational-legal) explains why people accept a regime’s authority.
- The six course countries differ in federal vs. unitary structure and in sources of legitimacy.
State, Nation, Regime, Government
Keep these distinct: the state is the permanent sovereign organization over a territory; a nation is a people sharing identity; a regime is the enduring set of rules and institutions; a government is the particular set of leaders in power now. A change of government (new PM or president) is shallow; a change of regime (new rules of the game) is deep.
Classifying Regimes
Liberal democracies combine competitive elections with protected rights and rule of law (UK). Illiberal or hybrid regimes hold elections but constrain competition and rights (Russia). Authoritarian regimes limit competition sharply (China), and theocracies place religious authority above elected institutions (Iran). Use civil-liberties and competition criteria to classify rather than the mere presence of elections.
Sovereignty, Legitimacy, and Structure
Sovereignty is supreme authority free of outside control; supranational bodies like the EU complicate it (Brexit). Legitimacy — the belief in a regime’s right to rule — comes from tradition, charisma, or rational-legal institutions. Federal systems (Nigeria, Russia, Mexico) share power with regions; unitary systems (UK, China, Iran) centralize it.
AP exam tip
On the exam, never use "government" when you mean "regime" or "state." Graders reward precise use of these three terms, and conflating them is the fastest way to lose concept-application points.
Connections to other units
- Unit 2: Regime type shapes which political institutions hold real power.
- Unit 3: Legitimacy connects to political culture and citizens’ willingness to participate.
- Unit 5: Sovereignty is tested by globalization and supranational organizations.
