Hitler and Mussolini both came to be dictators under Germany and Italy because of each countries state at the time. Meaning, it was easy to establish single party states because of the depression and major issues residing in both countries. For example, in Germany, their was trouble with production and unemployment, as well as a severe declining economy. When Hitler came to power, he made the country self sufficient in many things- which established totalitarian power by basically creating the Nazi Party which controlled military, economy, and more. Similarly Mussolini was supportive of a radicalized movement, and was able to cater crowds because of this. And since they both envisioned themselves as leaders, they were able to drive their countries to a totalitarian state.
