A dictatorship is an autocratic form of government which is characterized by a leader, or a group of leaders, who hold governmental powers with few to no limitations. Politics in a dictatorship are controlled by a dictator, and they are facilitated through an inner circle of elites that includes advisers, generals, and other high-ranking officials. The dictator maintains control by influencing and appeasing the inner circle and repressing any opposition, which may include rival political parties, armed resistance, or disloyal members of the dictator's inner circle. Dictatorships can be formed by a military coup that overthrows the previous government through force or they can be formed by a self-coup in which elected leaders make their rule permanent. Dictatorships are authoritarian or totalitarian, and they can be classified as military dictatorships, one-party dictatorships, personalist dictatorships, or absolute monarchies.

Autocracy is a system of government in which absolute power is held by the ruler, known as an autocrat. It includes most forms of monarchy and dictatorship, while it is contrasted with democracy and feudalism. Various definitions of autocracy exist. They may restrict autocracy to cases where power is held by a single individual, or they may define autocracy in a way that includes a group of rulers who wield absolute power. The autocrat has total control over the exercise of civil liberties within the autocracy, choosing under what circumstances they may be exercised, if at all. Governments may also blend elements of autocracy and democracy, forming an anocracy. The concept of autocracy has been recognized in political philosophy since ancient times.
