Acquisition of Territory in Illyria - Impression in Greece and Macedonia
But the Romans went further, and established themselves on the east coast. The Illyrians of Scodra were rendered tributary to Rome; Demetrius of Pharos, who had passed over from the service of Teuta to that of the Romans, was installed, as a dependent dynast and ally of Rome, over the islands and coasts of Dalmatia; the Greek cities Corcyra, Epidamnus, Apollonia, and the communities of the Atintanes and Parthini were attached to Rome under mild forms of symmachy.
These acquisitions on the east coast of the Adriatic were not sufficiently extensive to require the appointment of a special auxiliary consul; governors of subordinate rank appear to have been sent to Corcyra and perhaps also to other places, and the superintendence of these possessions seems to have been entrusted to the chief magistrates who administered Italy.(11)
11. A standing Roman commandant of Corcyra is apparently mentioned in Polyb. xxii. 15, 6 (erroneously translated by Liv. xxxviii. ii, comp. xlii. 37), and a similar one in the case of Issa in Liv. xliii. 9. We have, moreover, the analogy of the -praefectus pro legato insularum Baliarum- (Orelli, 732), and of the governor of Pandataria (Inscr. Reg. Neapol. 3528). It appears, accordingly, to have been a rule in the Roman administration to appoint non-senatorial -praefecti- for the more remote islands.
But these "deputies" presuppose in the nature of the case a superior magistrate who nominates and superintends them; and this superior magistracy can only have been at this period that of the consuls. Subsequently, after the erection of Macedonia and Gallia Cisalpina into provinces, the superior administration was committed to one of these two governors; the very territory now in question, the nucleus of the subsequent Roman province of Illyricum, belonged, as is well known, in part to Caesar's district of administration.
