 The province of Illyricum was constituted out of both Dalmatia and the newly conquered southern Pannonia, and, despite being a frontier province, was designated as a senatorial province.From 14 BC to 10 BC there were a series of rebellions in southern Pannonia and northern Dalmatia which Roman writers referred to as "Bellum Pannomicum" (the "Pannonian War").What little is known about these events comes chiefly from brief accounts by Cassius Dio and a few references by other authors, though there is no information about the causes.
