Why did the dictators/military leaders find widespread support among the people of their nation?

Most dictators, like Fidel Castro or Stalin, came to power by helping overthrow the previous government. They take leadership because usually they led the revolution, and after that, they enforce propaganda to make the people think that their country is the best in the world and that everyone has it really good. Most people in a dictated country are really unhappy, and they either revolt or just let themselves get beat down.
