AP Comparative Government compares political systems in the United Kingdom, Russia, China, Mexico, Iran, and Nigeria. This cheat sheet helps students organize the six required course countries by regime type, institutions, participation, and sources of legitimacy. Students need a compact reference because the exam often asks them to compare patterns across countries rather than memorize facts in isolation.
The most important ideas are how power is gained, limited, and used in each state. Core comparisons include democracy versus authoritarianism, unitary versus federal systems, parliamentary versus presidential structures, and secular versus theocratic authority. Strong answers connect institutions, political culture, civil society, elections, and state legitimacy to specific country evidence.
Key Facts
- The six AP Comparative Government countries are the United Kingdom, Russia, China, Mexico, Iran, and Nigeria.
- A regime is the set of rules and institutions that determines how political power is gained, used, and transferred.
- A state is sovereign when it has recognized authority over a defined territory and population.
- The United Kingdom is a parliamentary democracy with a unitary system, an uncodified constitution, and a fusion of executive and legislative power.
- Russia and China are authoritarian systems where elections or party structures exist, but real competition and civil liberties are heavily limited.
- Mexico and Nigeria are presidential federal republics where elections are competitive, but corruption, regional divisions, and weak rule of law can challenge accountability.
- Iran is a theocratic republic because elected institutions operate under unelected religious authority, especially the Supreme Leader and Guardian Council.
- A strong comparison uses country evidence plus a category of analysis, such as institutions, legitimacy, political participation, or civil society.
Vocabulary
- Regime
- A regime is the basic system of rules and institutions that determines how a government operates.
- Legitimacy
- Legitimacy is the public belief that a government has the right to rule.
- Federal System
- A federal system divides governing authority between a national government and regional governments.
- Unitary System
- A unitary system concentrates sovereignty in the national government, even if local governments perform important tasks.
- Authoritarianism
- Authoritarianism is a system in which leaders limit political competition, civil liberties, and meaningful public control over government.
- Civil Society
- Civil society is the network of voluntary groups, media, unions, religious organizations, and associations outside the state.
Common Mistakes to Avoid
- Calling the United Kingdom a presidential system is wrong because the prime minister comes from Parliament and depends on parliamentary support.
- Treating all elections as democratic is wrong because authoritarian states can hold elections while limiting opposition, media freedom, and real competition.
- Confusing federalism with democracy is wrong because federalism describes the division of power between levels of government, not whether citizens control leaders.
- Describing Iran as only democratic is wrong because elected offices are constrained by unelected religious institutions such as the Supreme Leader and Guardian Council.
- Using country facts without comparison is weak because AP responses must connect evidence to a larger concept, similarity, difference, or political consequence.
