Which type of authoritarian government can best be defined as a political and social system based on strict social-class distinctio?

Dictator government because it is that its system of government dictatorship is a modality that, invoking an alleged public interest, identified in reality with group interests, dispenses, to get it, the will of the governed. It is a power exercised by a person or group on the margins or above the laws, without being subject to control or any democratic control. The dictatorship excludes or obviates when it does not eliminate it, a division of the powers of the legislative, executive and judicial State, implying the restriction or suppression of freedom of expression, assembly, and association. As a rule, it is imposed by military coups d'etat backed by civil sectors professing a specific ideology, with hegemonic aspirations and authoritarian programs, particularly in situations of economic or political crisis. for example, In Marxist-Leninist theory, we speak of the dictatorship of the proletariat to refer to the form of government that the working class would implement once overthrown the capitalist system as a phase prior to the advent of communist society to consolidate and develop the revolutionary socialist process
