The ideology that supports direct rule of the state by one powerful leader is called "fascism". Fascism is a political ideology that advocates for a totalitarian government led by a single charismatic leader, who has absolute power and authority over the state and its citizens. In fascist regimes, individual rights and freedoms are often suppressed in favor of the collective interests of the state, and opposition to the ruling party is not tolerated. Some of the most well-known examples of fascist regimes in history include Nazi Germany under Adolf Hitler and Fascist Italy under Benito Mussolini.
