Authoritarianism is a political system characterized by concentrated power in a single authority or a small group, often limiting individual freedoms and suppressing dissent. In such regimes, political pluralism is typically absent, and the government may use coercion, Propaganda, and censorship to maintain control. Citizens often have little to no input in governance, and civil liberties are frequently curtailed. Common examples of authoritarianism include military dictatorships and one-party states.
