The main architect behind Fascism in Italy was Benito Mussolini. He founded the National Fascist Party in 1921 and became Italy's Prime Minister in 1922. Mussolini's ideology emphasized nationalism, authoritarianism, and militarism, promoting the idea of a strong centralized state. He sought to create a new Roman Empire and utilized propaganda, violence, and repression to consolidate power. Mussolini's regime aimed to suppress political dissent and strengthen Italy’s position in Europe through aggressive expansionist policies. His influence extended beyond Italy and helped shape fascist movements in other countries, leading to a broader European shift toward authoritarianism in the 20th century.
