AP Comparative Government compares how political systems gain power, organize institutions, respond to citizens, and make policy. This cheat sheet helps students review the six course countries, key concepts, and comparison tools in one place. It is useful for connecting vocabulary to real governments and for preparing short-answer, free-response, and multiple-choice questions.
The core ideas include sovereignty, authority, legitimacy, democratization, political institutions, civil society, and policy outcomes. Students should know how executives, legislatures, courts, parties, elections, and bureaucracies work in different regimes. Strong comparison uses evidence from course countries such as China, Iran, Mexico, Nigeria, Russia, and the United Kingdom.
Key Facts
- A state has sovereignty when it has independent legal authority over a defined territory and population.
- Legitimacy is the public belief that a government has the right to rule, often based on tradition, elections, ideology, religion, performance, or nationalism.
- A unitary system concentrates authority in the national government, while a federal system constitutionally divides power between national and regional governments.
- Democratization means a political system becomes more open, competitive, accountable, and protective of civil liberties.
- Political liberalization increases rights and freedoms, but democratization requires meaningful competition for power.
- Proportional representation usually increases party representation because seats are awarded based on each party's share of the vote.
- A parliamentary system fuses executive and legislative power because the prime minister and cabinet depend on legislative confidence.
- Turnout rate = number of voters / number of eligible voters x 100.
Vocabulary
- Regime
- A regime is the basic rules, institutions, and practices that determine how political power is gained and used.
- Civil Society
- Civil society is the network of voluntary groups, organizations, media, unions, and associations outside direct government control.
- Rule of Law
- Rule of law means government officials and citizens are expected to follow clear, public, and fairly enforced laws.
- Authoritarianism
- Authoritarianism is a system in which political power is concentrated and citizens have limited meaningful ability to challenge rulers.
- Political Socialization
- Political socialization is the process by which people form political beliefs through family, school, media, religion, peers, and state institutions.
- Corporatism
- Corporatism is a system in which the state manages interest representation by officially recognizing selected groups.
Common Mistakes to Avoid
- Confusing political liberalization with democratization is wrong because expanded freedoms do not always create competitive elections or peaceful transfers of power.
- Calling every elected government democratic is wrong because elections can be unfair, restricted, manipulated, or held without real opposition.
- Ignoring country evidence is wrong because AP Comparative Government responses must connect concepts to specific examples from course countries.
- Treating federalism and devolution as the same thing is wrong because federalism constitutionally divides power, while devolution transfers authority that the central government may be able to revise.
- Assuming proportional representation always creates stable governments is wrong because it can produce multiparty coalitions that are more representative but sometimes less stable.
