The terms authoritarianism and totalitarianism denote different forms of government. Authoritarianism refers to a political system characterized by concentrated power in a single authority, often suppressing political dissent and limiting civil liberties. Totalitarianism, on the other hand, represents an extreme form of authoritarianism where the state seeks to control all aspects of public and private life, including the economy, education, and even personal beliefs. While both systems restrict freedom, totalitarian regimes employ an extensive ideology, seeking to mobilize citizens and maintain complete control over society.
