Dictator

A dictator is a ruler who assumes sole and absolute power with military control but, without hereditary ascension such as an absolute monarch. When other states call the head of state of a particular state a dictator, that state is called a dictatorship. The word originated as the title of a magistrate in ancient Rome appointed by the Senate to rule the republic in times of emergency (see Roman dictator and justitium).Like the term tyrant, originally a respectable Ancient Greek title, and to a lesser degree autocrat, it came to be used almost exclusively as a non-titular term for oppressive, even abusive rule, yet had rare modern titular uses.
