Totalitarianism is a political system in which the state holds total control over every aspect of citizens’ lives and seeks to stamp out all opposition. It is characterized by a highly centralized, autocratic government, a one-party political system, strict control over the economy, propaganda and censorship, and the widespread use of secret police and a paramilitary force to maintain order.
