Totalitarian regimes are characterized by an absolute concentration of power in a single authority, often maintained through state control of multiple aspects of life, including politics, economy, and culture. These regimes typically suppress political dissent, limit civil liberties, and utilize propaganda to maintain their grip on power. Citizens are often subject to constant surveillance, and opposition is systematically eliminated or suppressed. The lack of political pluralism and civil society engagement further consolidates control, with the government exercising total control over the populace, often justified by a perceived need for stability or national security.
