Dictator

A dictator is a ruler who wields absolute power. A state ruled by a dictator is called a dictatorship. The word originated as the title of a magistrate in the Roman Republic appointed by the Senate to rule the republic in times of emergency (see Roman dictator and justitium).

Like the term "tyrant" (which was originally a respectable Ancient Greek title), and to a lesser degree "", "dictator" came to be used almost exclusively as a non-titular term for oppressive, even abusive rule, yet had rare modern titular use.

In modern usage, the term "dictator" is generally used to describe a leader who holds and/or abuses an extraordinary amount of personal power, especially the power to make laws without effective restraint by a legislative assembly. Dictatorships are often characterised by some of the following traits: suspension of elections and of civil liberties; proclamation of a state of emergency; rule by decree; repression of political opponents without abiding by rule of law procedures; these include one-party state, and cult of personality.

The term "dictator" is comparable to – but not synonymous with – the ancient concept of a tyrant; initially "tyrant", like "dictator", did not carry negative connotations. A wide variety of leaders coming to power in a number of different kinds of regimes, such as military juntas, one-party states and civilian governments under personal rule, have been described as dictators. They may hold left or right-wing views, or may be apolitical.
