After Lenin's death, Stalin seized power in the Soviet Union and transformed it into a totalitarian state where the government exercised total control over public and private life. Totalitarian regimes like Stalin's used police terror and indoctrination to maintain control, repressing dissent and standardizing thought. More recent dictators in the 20th century, such as Hitler, Mussolini, and Saddam Hussein, employed similar totalitarian tactics to consolidate authority over their populations and economies. While there are few outright totalitarian governments today, authoritarian regimes still exist that strive to regulate all aspects of society.
