A king-emperor or queen-empress is a sovereign ruler who is simultaneously a king or queen of one polity and emperor or empress of another. This dual title usually results from merger of one royal and one imperial crown (ruling office), but recognises the two polities as politically distinct and their supreme magistracies, i. e., political offices, as different in form. It also denotes the imperial status of a king who holds it by virtue of acquisition of an empire or vice versa.
