This document discusses political regimes, power, and legitimacy. It defines a regime as the rules a state sets and follows in exerting power. There are different types of regimes including democracies, which base authority on the will of the people, and authoritarianism, where decisions are made by political elites without citizen input. Legitimacy can come from tradition, charismatic leaders, or rational-legal systems based on established laws. Political culture and ideologies also influence a regime's power structure and claims to legitimacy.
