The difference between a democratic regime and an authoritarian regime lies in the level of political freedom and citizen participation. In a democracy, power is derived from the people, characterized by free and fair elections, rule of law, and protection of civil liberties. Citizens have the right to participate in governance and express dissent. In contrast, authoritarian regimes concentrate power in a single leader or a ruling party, often suppressing political opposition, limiting freedoms, and controlling media, leading to political repression and reduced individual rights.
