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.
Practice Questions
- 1 List the 6 AP Comparative Government countries and identify each as primarily democratic, authoritarian, hybrid, or theocratic.
- 2 Out of the 6 course countries, how many are federal systems, and which countries are they?
- 3 If a short-answer question asks for 2 examples of institutions that limit democracy, choose 2 countries and name one institution or practice from each.
- 4 Explain why a country can have elections but still lack full democratic accountability.
Understanding AP Comparative Government Six Countries
Comparative government becomes more useful when students separate formal rules from actual power. A constitution may describe elections, courts, legislatures, and rights, yet informal networks can decide who gets access to office or state resources. In the United Kingdom, the government must retain support in Parliament, so party discipline matters greatly.
In China, the Chinese Communist Party shapes major appointments and policy direction through party channels that operate alongside state institutions. In Iran, candidates can seek elected office only after review by the Guardian Council.
These examples show why an institution cannot be understood by its title alone. Students should ask who selects leaders, who can block decisions, and whether rules are applied consistently.
Federalism has different effects depending on the strength of national and regional institutions. Mexico and Nigeria both divide authority between national and subnational governments, but governors, local political machines, ethnic communities, and resource distribution can make that division especially important. In Nigeria, oil revenue has created major disputes over which regions receive public funds and who controls production.
Ethnic and religious differences can shape voting patterns, party coalitions, and conflict. In Mexico, local officials may have different levels of capacity and public trust than the national government. This matters in daily life because education, policing, roads, permits, and public services are often delivered locally.
A federal system does not automatically protect liberty or create effective government. Its results depend on accountability, funding, and the rule of law.
Legitimacy means that people accept a government’s right to rule, at least enough for the system to continue. Elections are one source, but they are not the only source. Governments may claim legitimacy through religion, historical tradition, nationalism, economic growth, security, or the delivery of public services.
Iran uses religious authority as a central basis for rule. China often emphasizes national development and social stability. The United Kingdom draws partly on long established institutions and regular electoral competition.
Legitimacy can weaken when citizens face corruption, unequal treatment, economic hardship, or violence. Protests, low turnout, distrust of parties, and support for populist leaders can all signal a legitimacy problem. Students should avoid assuming that public obedience always means genuine support, since fear and limited alternatives can produce obedience too.
For exam writing, use a clear comparison chain. Name a shared category, give precise evidence from each country, then explain the consequence. For example, a response could compare how candidate selection affects political competition.
Party leaders have strong influence over candidates in the United Kingdom, while the Guardian Council can disqualify candidates in Iran. The key point is not merely that the systems differ. Explain that different selection rules change voter choice and limit or expand accountability.
Pay attention to command terms. A prompt asking for a similarity needs a real common pattern, not two unrelated facts.
A prompt asking for an explanation needs cause and effect. Accurate country evidence is important, but the analysis earns its value by showing how political structures shape people’s choices and government outcomes.
