How did the dictatorial regimes that gained power in the years after world war 1 acquire and maintain their power?

Dictatorial regimes that emerged after World War I often acquired power through a combination of political instability, economic hardship, and social unrest, exploiting the discontent of the populace. They maintained control by employing Propaganda, suppressing dissent, and using state violence, including secret police and military force, to eliminate opposition. Additionally, these regimes frequently manipulated nationalist sentiments and promised stability and order in the face of chaos, thereby garnering public support. The consolidation of power was often facilitated by the dissolution of democratic institutions and the erosion of civil liberties.
