Illyrian people Taulantii, during the period of foundation of Syracuse, Sicily. Appian also wrote that they possessed Epidamnus in Albania, but both accounts, although possibly anachronistic, don't seem impossible. They are probably a reflection of Illyrian southward migration during the Early Iron Age (c. 1000 BCE). The fall of Liburnian domination in the Adriatic Sea and their final retreat to their ethnic region (Liburnia) were caused by the military and political activities of Dionysius the Elder of Syracuse (406 – 367 BC). The imperial power base of this Syracusan tyrant stemmed from a huge naval fleet of 300 tetreras and penteras. After he ended Carthaginian authority in Sicily, he turned against the Etruscans. He made use of the Celtic invasion of Italy, and the Celts became his allies in the Italian peninsula (386 - 385 BC). This alliance was crucial for his politics, then focusing on the Adriatic Sea, where the Liburnians still dominated. In light of this strategy, he established a few Syracusan colonies on the coasts of the Adriatic Sea: Adria at the mouth of Po river and Ancona at the western Adriatic coast, Issa on the outermost island of the central Adriatic archipelago (island of Vis) and others. Meanwhile, in 385-384 BC he helped colonists from the Greek island of Paros to establish Pharos (Starigrad) colony on the Liburnian island of Hvar, thus taking control of the important points and navigable routes in the southern, central and northern Adriatic. The name of the Vindelician town of Cambodunum (today Kempten) is apparently derived from the Celtic cambo dunon: "fortified place at the river bend" . One classical source, Servius' commentary on Virgil's Aeneid, says on the contrary that the Vindelicians were originally Liburnians – a non-Celtic Indo-European people from the northeastern shores of the Adriatic (modern Croatia). This caused a simultaneous Liburnian resistance on both coasts, whether in their ethnic domain or on the western coast, where their possessions or interests were in danger. A great naval battle was recorded a year after the establishment of Pharos colony, by a Greek inscription in Pharos (384 – 383 BC) and by the Greek historian Diodorus Siculus (80 – 29 BC), initiated by conflicts between the Greek colonists and the indigenous Hvar islanders, who asked their compatriots for support. 10,000 Liburnians sailed out from their capital Idassa (Zadar), led by the Iadasinoi (people of Zadar), and laid siege to Pharos.
