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 Pannonicum" (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. The Roman sources had little interest in events in Illyria from the campaigns of Augustus in 35–33 BC to 16 BC. Cassius Dio wrote that in that year the governor of Illyria for 17–16 BC, Publius Silius Nerva, went to fight in the Italian Alps because there were no troops there. Some Pannonians and Noricans entered Istria and pillaged it. Silius Nerva quickly brought the situation under control. At the same time there was a small rebellion in Dalmatia. The Dentheletae, together with the Scordisci, who lived in present-day Serbia at the confluence of the Rivers Savus (Sava), Dravus (Drava), and Danube, attacked the Roman province of Macedonia. A civil war broke out in Thrace. In 15 BC the Romans conquered the Scordisci and annexed Noricum and conducted other operations in other parts of the Alps against the Rhaeti and Vindelici. In 13 BC, Augustus gave Marcus Vipsanius Agrippa, his most important ally, the supreme command in Illyricum. Agrippa found a negotiated solution; however, he died suddenly and the treaty was ignored. Command was then given to Tiberius, who finally defeated the Illyrians. Roman military operations in Illyricum might have started by the time of Marcus Vinicius' governorship in 14–13 BC. The Pannonian War led to Illyricum being redesignated an imperial province.
