This paper re-examines the role of ‘client kings’ in the Roman east in the early Principate. Contrary to previous emphasis on continuity with the republican past, it proposes that Octavian-Augustus enacted a set of measures that fundamentally changed the relations of certain eastern monarchs with the imperial centre. These ‘provincial monarchs’ became a new elite of Roman administrators, personally loyal to the domus Augusta and distinct from ‘client kings’ earlier and elsewhere. This Augustan systemisation complemented the provincial division of 27 b.c.e., creating a ‘divide and rule’ dynamic between provincial monarchs and imperial legates which was expedient to the Julio-Claudians. This model is then used to challenge the view that the Flavians systematically ‘provincialised’ the east as part of a reorganisation of the frontier. It raises the alternative possibility that provincial monarchy gradually died out, following the Flavians’ realisation that its continued maintenance was detrimental to their public image in Rome.
