Political systems, regimes, and governments form the foundational framework for understanding how power is organized, exercised, and legitimized across different countries. This area of comparative politics examines the structures and processes through which societies make collective decisions, allocate resources, and maintain order.
Regime classification lies at the heart of this field. Scholars distinguish among democracies, authoritarian regimes, and hybrid regimes based on criteria such as competitive elections, civil liberties, rule of law, and accountability. The AP Comparative Government course focuses on six countries: China, Iran, Mexico, Nigeria, Russia, and the United Kingdom as case studies.
Legitimacy underpins the stability of any political system. Max Weber identified three ideal types of legitimate authority: traditional, charismatic, and rational-legal.
