Oligarchia
Oligarchia (Graece ὀλιγαρχία > ὀλίγος 'paucus' + ἄρχω 'rego, impero') est genus structurae potestatis in qua potestas paucis hominibus aut parvo factioni est. Qui homines moderatione nobilitatis, divitiarum, coniunctionum familiarium, educationis, corporationis, religionis, politicae, militaris distingui possunt. Civitates oligarchicae a familiis saepe reguntur quae ab una ad proximam aetatem usitate transmittunt, sed hereditas non est condicio necessaria. Monarchia autem est dominatio unius hominis.

Oligarchiae saepe per historiam sunt tyrannicae, oboedentia publica vel etiam oppressione ut existat nitens. Aristoteles quidem hoc vocabulo primus utebatur ut synonymum regiminis hominum divitum, pro qua sententia plutocratia, aliud vocabulum, hodie saepe adhibetur.
