Authoritarian regimes maintain control through a combination of repression, propaganda, and manipulation of political structures. They often suppress dissent by curbing free speech, controlling the media, and eliminating rival political groups. Fear tactics, such as surveillance or imprisonment, serve to intimidate citizens from opposing the state. Additionally, these regimes may utilize ideological indoctrination to reinforce loyalty among the populace and justify their rule. By controlling information and stifling opposition, authoritarian leaders aim to ensure their grip on power remains unchallenged.
