Unit 1: Political Systems, Regimes, and Governments

Unit 1 supplies the vocabulary the rest of the course depends on: state, nation, regime, government, sovereignty, legitimacy, and power. It distinguishes democratic from authoritarian regimes and unitary from federal structures, using the six course countries as illustrations. Getting these definitions exactly right pays off on every later free-response question.

Sample Systems and Regimes questions

Practice questions, not yet expert-reviewed

Original practice questions written to the published framework for this section. No expert has reviewed them, and they are not taken from any official exam. Try each one before you open the answer.

Question 1Foundational
Which term names the enduring set of rules and institutions that determine how political power is organized and exercised, and that normally outlasts any particular set of officeholders?
1. ARegime
2. BGovernment
3. CNation
4. DBureaucracy
Show answer
Answer: A. Regime
A regime is the durable framework of rules through which power is held and used, while a government is the specific group of people currently occupying those offices. Government is the tempting distractor precisely because governments change often within a single stable regime.
Key insight: Governments come and go through elections; regime change means the rules of the game themselves have been replaced.
Question 2Foundational
Which of the six AP Comparative Government course countries combines elected institutions with a clerical Supreme Leader who holds final authority, making it a theocratic republic?
1. AIran
2. BChina
3. CRussia
4. DNigeria
Show answer
Answer: A. Iran
Iran layers an elected president and Majlis beneath an unelected Supreme Leader and clerical bodies whose religious authority overrides electoral outcomes. China is the tempting distractor as another authoritarian case, but its ruling authority is a secular Communist Party rather than a religious hierarchy.
Key insight: Iran is the course's theocracy: elections exist, but clerical institutions decide who may run and what may become law.
Question 3Intermediate
In Max Weber's typology of authority, which source of legitimacy rests on established laws, written procedures, and the offices themselves rather than on custom or personal appeal?
1. ARational-legal legitimacy
2. BTraditional legitimacy
3. CCharismatic legitimacy
4. DCoercive legitimacy
Show answer
Answer: A. Rational-legal legitimacy
Rational-legal legitimacy attaches to the office and the legal process that fills it, which is why an unpopular official still holds real authority. Charismatic legitimacy is the tempting distractor, but it depends on the personal qualities of a specific leader and rarely survives that leader's departure.
Key insight: Ask what people are obeying: the law, the tradition, or the person. That answer names the type of legitimacy.
Question 4Intermediate
Which course country remains constitutionally unitary yet has transferred substantial legislative powers to elected bodies in Scotland, Wales, and Northern Ireland?
1. AThe United Kingdom
2. BNigeria
3. CMexico
4. DRussia
Show answer
Answer: A. The United Kingdom
Devolution granted the Scottish Parliament and the Welsh and Northern Ireland assemblies real policy authority, but Parliament at Westminster retains legal sovereignty and could in principle reclaim those powers. Nigeria is the tempting distractor because it also manages regional diversity, but Nigeria does so through a constitutionally entrenched federal system rather than delegated devolution.
Key insight: Devolution is power lent by a unitary center; federalism is power that belongs to the regions by constitutional right.
Question 5Advanced
What term describes a regime that holds regular multiparty elections but restricts civil liberties, press freedom, and opposition organizing so that incumbents rarely lose?
1. AIlliberal democracy
2. BLiberal democracy
3. CTotalitarian regime
4. DFailed state
Show answer
Answer: A. Illiberal democracy
An illiberal democracy keeps the electoral form while hollowing out the freedoms that make elections meaningful; Russia is the course country most often placed in this category, though as its restrictions have tightened many observers now classify it as authoritarian outright. Totalitarian regime is the tempting distractor, but totalitarianism seeks to control private life and ideology entirely and does not bother maintaining competitive elections.
Key insight: Elections alone do not make a democracy liberal; rights, a free press, and a real opposition are what give a vote its meaning.
