Emperor

Emperor was a (male) monarch, usually the sovereign ruler of an empire or another type of imperial realm. Empress, the female equivalent, may indicate an emperor's wife (empress consort) or a woman who rules in her own right (empress regnant). Emperors are generally recognised to be of a higher honour and rank than kings.
