AP Comparative Government Unit 1 Review: Political Systems and Government Types

Comparative politics builds knowledge by analyzing data across countries. Political scientists use both quantitative indexes and qualitative sources, and they must carefully distinguish correlation from causation. Because many variables affect political outcomes simultaneously, establishing causation is difficult. Key indexes you must know for the exam include Freedom House (political freedoms and civil liberties), the Human Development Index (life expectancy, education, income), GDP per capita, the Gini Index (income inequality), and the Corruption Perceptions Index.

• Empirical vs. normative: Empirical statements are factual and observable; normative statements express value judgments. Political scientists prioritize empirical claims when comparing countries.
• Correlation vs. causation: Two variables can move together (correlation) without one causing the other. Causation requires ruling out confounding variables, which is hard in comparative politics.
• Freedom House: Rates countries on political rights and civil liberties; used to compare regime openness across course countries.
• Gini Index: Measures income inequality within a country; higher values indicate greater inequality.
• Human Development Index (HDI): Combines life expectancy, education, and income per capita to measure overall development beyond GDP alone.

These four terms are frequently confused and frequently tested. A state combines a permanent population, governing institutions, defined territory, and international recognition. A regime is the set of fundamental rules controlling access to and exercise of power; regimes typically outlast individual governments. A government is the specific set of institutions or officeholders making binding decisions right now. A nation is a group of people sharing a common identity, which may or may not align with state borders. Weber's concept of the state as holding a monopoly on the legitimate use of force is foundational here.

• State: A political organization with a permanent population, governing institutions, defined territory, and international recognition.
• Regime: The fundamental rules controlling access to and exercise of political power; regimes endure across multiple governments.
• Government: The specific institutions or individuals legally empowered to make binding decisions for a state at a given time.
• Nation: A group of people sharing a common identity (ethnic, cultural, linguistic); does not require its own state.
• Monopoly on legitimate force: Weber's definition of the state: only the state has the recognized right to use coercive force within its territory.

Democracy and authoritarianism are best understood as a spectrum rather than a binary. The key indicators for placing a regime on that spectrum are: adherence to rule of law, degree of media freedom, competitiveness and fairness of elections, government transparency, and the nature of citizen participation. Democratic regimes feature independent branches that check each other; authoritarian regimes concentrate power and limit competition. Authoritarian subtypes include illiberal democracies, hybrid regimes, one-party states, theocracies, and totalitarian governments. Russia and Iran are frequently used to illustrate hybrid and theocratic regimes respectively.

• Rule of law: The principle that all individuals and institutions, including the government, are subject to and accountable to the law.
• Hybrid regime: A political system combining democratic elements like elections with authoritarian features like restricted civil liberties and limited competition.
• Illiberal democracy: Elections occur but individual rights, judicial independence, and checks on executive power are weak.
• Totalitarian government: A regime exercising comprehensive control over all aspects of public and private life, including economy, culture, and society.
• Separation of powers: Division of authority among executive, legislative, and judicial branches to prevent any one branch from dominating.

Democratization is the process of transitioning from authoritarian rule toward democratic governance. It is not linear: the process can stall or reverse (democratic backsliding). Goals of democratization include fairer elections, universal adult suffrage, protected civil rights, greater transparency, equal treatment, and rule of law. Electoral system design matters: proportional representation, gender quotas, and adjusted vote thresholds can increase multiparty competition and accommodate ethnic diversity. Political corruption is a major obstacle; independent judiciaries help reduce it. Mexico's transition away from PRI dominance and Nigeria's shift to a multiparty republic after military rule are key course examples.

• Democratization: The transition from an authoritarian regime toward a democratic one, aiming for competitive elections, civil rights, and rule of law over time.
• Democratic backsliding: A reversal or stalling of democratization, where a regime moves toward greater authoritarianism after a period of democratic progress.
• Proportional representation: An electoral system allocating legislative seats based on each party's share of the vote, increasing multiparty competition.
• Consolidated democracy: A democracy where institutions and practices are stable and widely accepted, making a return to authoritarianism unlikely.
• Political corruption: Abuse of public office for private gain; a major obstacle to democratization that independent judiciaries can help reduce.

Sources of power and authority include constitutions, religion, military forces, political parties, legislatures, and popular support. Each course country illustrates a different combination: China's Communist Party controls the military to maintain regime stability; Iran's 1979 Revolution replaced dictatorship with theocracy based on Islamic Sharia law; Mexico and Nigeria transitioned to multiparty republics after military rule and single-party dominance; Russia's political elite backs a strong president in a managed democracy; the UK has devolved power through constitutional reforms. Regime change occurs when the fundamental rules are replaced, either incrementally or suddenly, through elections, coups, or revolutions. Government change is more routine and can happen through elections, appointments, or lines of succession. Violent transitions, as in Iran's 1979 Revolution and Nigeria's military coups, illustrate sudden regime change.

• Regime change: Replacement of the fundamental rules and institutions of a political system, occurring suddenly (coup, revolution) or incrementally.
• Coup d'etat: A sudden, often violent seizure of power by a group, typically the military, replacing the existing government or regime.
• Managed democracy: A system where elections exist but are structured to favor a dominant party or leader, as in Russia.
• Lines of succession: Established rules determining who assumes power when a leader leaves office, enabling peaceful government transitions.
• 1979 Revolution: The Iranian Revolution that overthrew the Shah and established a theocracy based on Islamic Sharia law, a key example of sudden regime change.

Federal systems divide power between national and regional governments, giving subnational units a degree of local autonomy over services like education and social programs. Unitary systems concentrate power at the national level, producing more uniform policies. Among the course countries, Mexico, Nigeria, and Russia are federal; China, Iran, and the United Kingdom are unitary. The degree of centralization can shift over time in both types: the UK has devolved significant authority to Scotland, Wales, and Northern Ireland, while Russia has recentralized power through presidential envoys overseeing federal districts. Ethnic cleavages and supranational organizations like the EU can also drive changes in how power is distributed.

• Federalism: A system dividing power between national and regional governments, with each level holding constitutionally protected authority.
• Unitary state: A system concentrating power at the national level; subnational governments exist at the center's discretion.
• Devolution: The transfer of authority from a central government to regional governments, as the UK did with Scotland, Wales, and Northern Ireland.
• Local autonomy: The degree of independent decision-making authority granted to regional or local governments within a federal system.
• Presidential envoys: Representatives appointed by Russia's president to oversee federal districts, a mechanism for recentralizing control over regions.

Legitimacy is the public belief that a government has the right to use power. It is distinct from raw power: a government with legitimacy can govern with less coercion. Sources of legitimacy include popular elections, constitutional provisions, nationalism, tradition, governmental effectiveness, economic growth, ideology, religious heritage, and dominant party endorsement. Governments sustain legitimacy through effective policy delivery, peaceful transfers of power, reduced corruption, and economic development. Legitimacy erodes when corruption increases, electoral competition shrinks, or the economy performs poorly. Devolution can both enhance legitimacy by matching policies to local needs and weaken it by creating regional grievances.

• Legitimacy: The public belief that a government has the right to rule and use power; reduces the need for coercion.
• Charismatic authority: Authority derived from a leader's personal appeal and perceived exceptional qualities rather than legal rules or tradition.
• Governmental effectiveness: A government's ability to deliver services and implement policies efficiently; a key source of legitimacy for both democratic and authoritarian regimes.
• Political efficacy: Citizens' belief that they can understand and influence political outcomes; higher efficacy supports regime legitimacy.
• Constitutional provisions: A source of legitimacy derived from a government's legal framework establishing its authority to rule.

Internal actors can bolster or undermine regime stability and rule of law. The six course countries illustrate contrasting approaches to corruption, protest, and separatist violence. China uses the 'flies and tigers' anti-corruption campaign to target opponents while suppressing protest (Tiananmen 1989, Hong Kong 2020). Iran deploys the Revolutionary Guard and morality police against dissent, as seen in the Mahsa Amini protests. Mexico faces drug cartel violence and has created anti-corruption institutions like the National Electoral Institute. Nigeria contends with ethnic separatism, Boko Haram, and prebendalism. Russia restricts NGOs and jails opposition figures like Navalny. Authoritarian regimes also limit internal actors to attract foreign direct investment and improve economic growth.

• Protest movements: Collective actions by citizens seeking political or social change; can reinforce or threaten regime stability depending on state response.
• Separatist group violence: Violence by groups seeking independence or autonomy from a larger state, challenging territorial integrity and rule of law.
• Prebendalism: A system of political patronage in which leaders exploit state resources for personal gain, a significant stability challenge in Nigeria.
• Flies and tigers campaign: China's anti-corruption campaign under Xi Jinping that targets both low-level officials (flies) and high-ranking ones (tigers), also used to remove political rivals.
• Revolutionary Guard: Iran's elite military force reporting directly to the Supreme Leader, used to suppress internal dissent and enforce regime authority.
