In 35 BC, the Iapydes, the northernmost tribe of Dalmatia, carried out raids into northeastern Italy. They attacked Aquileia, and plundered Tergestus (Trieste). From 35–33 BC Octavian (who would soon become the emperor Augustus) undertook military campaigns in the region. He defeated the Iapydes and then pushed into southern Pannonia, where he seized the city of Segesta (which later, as a Roman town, was called Siscia). He then turned on the Dalmatians and captured Promona (to the south of modern Knin, Croatia) on the coast, the main city of the Liburnians, which had been seized by the Dalmatians. After that he took the Dalmatian cities of Sunodium and Setovia. He then moved upon the Derbani, who sued for peace. He also destroyed the settlements on the islands of Melite (Mljet) and Melaina Corcyra (Korčula), and deprived the Liburnians of their ships, because all were involved in piracy. Octavian's lieutenants conducted various other operations in the region. Octavian temporarily restored Roman authority in Dalmatia and pushed into southern Pannonia, which had never before been reached by Roman armies.
