A dictator is a ruler (e.g. absolutist or autocratic) who assumes sole and absolute power (sometimes, but not always, with military control sometimes with bribes) 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).
