What are the theories of totalitarianism?

Theories of totalitarianism explore the nature and functioning of regimes that seek to exert total control over public and private life. Key theorists, such as Carl Friedrich and Zbigniew Brzezinski, define totalitarianism through characteristics like an official ideology, a single ruling party, state control of the economy, and the use of terror. Other theories emphasize the psychological and social mechanisms that enable such regimes to maintain power, including Propaganda, surveillance, and repression of dissent. Overall, these theories aim to understand how totalitarian systems emerge, sustain themselves, and impact individual freedoms and societal structures.
