Rule by a king or queen, usually of one family or dynasty or aristocratic clan or house that manages to acquire an empire. Pure monarchy, although common in primitive societies, is exceedingly rare in modern times. There are, however, numerous petty egomaniacs and eccentrics throughout the galaxy who have set up their own principalities, kingdoms as so on.
Monarchic traditions also live on in some contemporary governments, although the monarch is no longer an absolute ruler, relegated to a more symbolic status. Examples include the Braccattian Kingdom, the Daglian Assembly of Clans and, historically, the former Orceronian Ruling Court.
