Mussolini used extensive propaganda to strengthen his fascist regime in Italy. He exploited Italy's Roman past in architecture and monuments to impress people and link fascism to Italy's former glory. Propaganda developed gradually through the press, radio, film, and posters. While these media helped spread fascist messages, they were not always effective due to censorship of opposing views, bureaucratic inefficiency, and Italians sometimes believing propaganda out of self-interest rather than belief in fascism. Mussolini also used culture for propaganda by promoting fascist-themed art and literature, though faced challenges controlling intellectual thought.
