Definition of tyranny. Tyranny is usually thought of as cruel and oppressive, and it often is, but the original definition of the term was rule by persons who lack legitimacy, whether they be malign or benevolent. Historically, benign tyrannies have tended to be insecure, and to try to maintain their power by becoming increasingly oppressive.
The Oxford English Dictionary offers alternative definitions: a ruler, an illegitimate ruler (a usurper), an absolute ruler (despot) or an oppressive, unjust or cruel ruler. The term is usually applied to vicious dictators who achieve bad results for the governed. The definition of a tyrant is cursed by subjectivity. Oppression, injustice and cruelty do not have standardized measurements or thresholds. The Greeks defined both usurpers and those inheriting rule from usurpers as tyrants.
