The term 'Father of Fascism' primarily refers to Benito Mussolini, the Italian political leader who founded the Fascist Party and ruled Italy as a dictator from 1922 to 1943. Mussolini's ideology emphasized authoritarianism, nationalism, and the importance of a strong, centralized state, which became key characteristics of fascism. His influence on the development of fascist movements across Europe set the stage for the rise of totalitarian regimes in the early 20th century.
