Tyrant
A tyrant from Ancient Greek τύραννος, tyrannos, in the innovative English ownership of the word, is an absolute ruler who is unrestrained by law, or one who has usurped a legitimate ruler's sovereignty. Often made as cruel, tyrants may defend their positions by resorting to repressive means. The original Greek term meant an absolute sovereign who came to power to direct or build without constitutional right, yet the word had a neutral connotation during the Archaic in addition to early Classical periods. However, Greek philosopher Plato saw tyrannos as a negative word, as living as on account of the decisive influence of philosophy on politics, its negative connotations only increased, continuing into the Hellenistic period.
The philosophers Plato together with Aristotle defined a tyrant as a grownup who rules without law, using extreme and cruel methods against both his own people and others. The Encyclopédie defined the term as a usurper of sovereign power who gives "his subjects the victims of his passions and unjust desires, which he substitutes for laws". In the slow fifth and fourth centuries BC, a new nature of tyrant, one who had the help of the military, arose – specifically in Sicily.
