In late Iron Age and early classical antiquity, the first polities of the area would be created by tribal groupings, including the Taulantii and Dardani. The most powerful Illyrian states of the area, the Ardiaean kingdom, emerged in the 3rd century BC during the rule of Agron and Teuta. The Illyrians came into conflict with Roman Republic and were defeated in the Illyrian Wars, which were followed by many revolts. The largest and last of them was the Great Illyrian Revolt (6-9 BC). The beginning of the integration of the region of Illyria in the Roman world followed the revolt and saw many Illyrians rise through the ranks of the Roman society and the Roman army in particular which produced several emperors of Illyrian origin.
In 231 BC, Agron possessed the most powerful land army and navy, of any of the kings who had reigned before him. He extended the kingdoms' borders in the north and south.
Ballaios ruled over the eastern Adriatic with capital at Rhizon. He is attested only from silver and bronze coinage, found abundantly along both coasts of the Adriatic. He is considered as the predecessor of Agron.
Bardylis was the founder of the first attested Illyrian dynasty. Macedonian campaigns proved successful in 393, 372 and 359 BC and invaded Epirus in alliance with Dionysius of Syracuse.
Bardyllis II was the son of Cleitus (r. 295–290 BC). He managed to re-create the state of his grandfather in the region of Dassaretis to the west of the Lynkestian lake.
Flavius Valentinianus II was the Emperor of the Roman Empire from 375 to 392.
Historical rulers
Enchelean-Taulantian rulers
Galaurus: king of Taulantii. Unsuccessfully invaded Macedonia between 678 and 640 BC.
Grabos I (5th century BC): attested on an Athenian inscription, he was very likely a person with great political responsibilities. He probably was the grandfather of Grabos II.
Grabos II (r. 358–356 BC): entered Athenian alliance to resist Philip's power in 356 BC.
Pleuratus I (r. 356–335 BC): reigned near the Adriatic coast in southern Illyria. In a losing effort in 344 BC, tried to thwart Philip's advances in Illyria.
Pleurias (r. c. 337/336 BC): Illyrian ruler who campaigned against Philip II about 337 BC. He is considered by some scholars as king of either the Autariatae, the Taulantii, or the Dardani. Some have suggested that he was the same as Pleuratus I; Pleurias is mentioned only in Diodorus (16.93.6), elsewhere unattested in ancient sources.
Glaucias: king of Taulantii. He aided Cleitus at the Battle of Pelion in 335 BC, raised Pyrrhus of Epirus and was involved in other events in southern Illyria in the late 4th century BC.
