Tyrant
From Conservapedia
A tyrant is a term the Greeks used to describe a person who seized and held power in violation of the normal laws and traditions of the community. Tyrants appeared in many Greek city states in the seventh and sixth centuries B.C. often taking advantage of the disaffection of the middle class against the old elite.
