The correct answer to this open question is the following.
In those years, the rise of totalitarian states was a common event in Russia, Italy, and Germany. Poverty, lack of jobs, troubles in society, and weak leadership were the common denominators in the rising of totalitarianism.
We have the cases of the governments of Joseph Stalin in the Soviet Union, Adolph Hitler in Germany, Benito Mussolini in Italy, and even Francisco Franco in Spain.
In totalitarian states, political power relies on a dictator, all media is controlled by the central government, and secret police arrest individuals without a warrant. You cannot think against the dictator.
In a totalitarian state, the dictator has absolute power and control of everything. People cannot speak against the government and the media is controlled by the state. The government maintains strict control over newspapers, radio, TV, and the internet, and all political power is held by a single party.
