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.
A tyrannical ruler wields absolute power and authority, and often wields that power unjustly, cruelly, or oppressively. Tyrannical rule is the opposite of democratic rule, which places the power in the people, the majority of whom makes the decisions.
