Emperor

An emperor was a male monarch, usually the sovereign ruler of an empire or another type of imperial realm.

An empress, the female equivalent, could be an emperor's wife (empress consort) or, in Queen Victoria's case, a woman who ruled in her own right (empress regnant). (TV: Tooth and Claw) An empress' husband was sometimes an emperor consort. (AUDIO: Empire of the Racnoss) Emperors were generally recognised to be of a higher honour and rank than kings.
