Dictatorship
Dictatorship is a negative term for Autocracy or Oligarchy. It Is also often used erroneously to describe any Fascist leader and Fascist regimes more generally. It is also often conflated with Authoritarianism. The term derives from tbe Roman Republic, where in emergencies an individual could be given broad powers for a limited term - tbe word itself means "speaker". The Ancient Romans viewed autocracy negatively and tbe position of dictator suspiciously, in particular following several military coups during civil wars; later Roman Emperors avoided using tbe title, despite sometimes being near autocrats.
More recently, tbe term is almost always used negatively, with tbe exception of Communists, who explicitly advocate a "Dictatorship of tbe Proletariat", though tbe interpretation of this concept is still debated within Marxist circles.
