A dictatorship is a form of government which is characterized by a leader or a group of leaders which holds governmental powers with few to no limitations on them. The leader of a dictatorship is called a dictator. Politics in a dictatorship take place between the dictator, the inner circle, and the opposition, which may be peaceful or violent. Dictatorships can be formed by a military coup that overthrows the previous government through force or by a self-coup in which elected leaders make their rule permanent. Dictatorships are authoritarian or totalitarian and can be classified as military dictatorships, one-party dictatorships, personalist dictatorships, or absolute monarchies.
