"The Origins of Totalitarianism" is a book by political theorist Hannah Arendt, published in 1951. It explores the rise of totalitarian regimes in the 20th century, particularly focusing on Nazi Germany and Stalinist Russia. Arendt examines how these governments used ideology, propaganda, and terror to control society and eliminate dissent. Arendt argues that totalitarianism is distinct from other forms of government due to its aim of total domination over all aspects of life. She discusses the role of mass movements, the manipulation of truth, and the impact of imperialism in creating conditions that allow totalitarian systems to thrive.
