Regardless of the number of the alternately ruling dynasties, of their tribal affiliation, and of the actual extension of their kingdom, it represented an alliance of Illyrian tribes that united under the rulership of a single leader, expressly referred to as "King of the Illyrians" in ancient historical records (whether in Ancient Greek or in Latin).
The kingdom of the Taulantii on the south-eastern coast of the Adriatic evidently reached its apex under Glaukias' rule and dominated southern Illyrian affairs in the late 4th century BC, exerting great influence on the Epirote state through the close ties with the Molossian king Pyrrhus.
It became a formidable power both on land and sea by assembling a great army and fleet, and directly ruling over a large area made up of different Illyrian tribes and cities that stretched from the Neretva River in the north to the borders of Epirus in the south, while its influence extended throughout Epirus and down into Acarnania.
[4] It seems that the weakening of the dynasty of Enchelae resulted in their assimilation and inclusion into a newly established Illyrian realm at the latest in the 5th century BC, marking the arising of the Dassaretii, who appear to have replaced the Enchelei in the Lakeland area of Lychnidus.
[5] The weakening of the Enchelean realm was also caused by the strengthening of another Illyrian dynasty established in its vicinity—that of the Taulantii—which existed for some time along with that of the Enchelei.
[6] The Taulantii—another people among the more anciently known groups of Illyrian tribes—lived on the Adriatic coast of southern Illyria (modern Albania), dominating at various times much of the plain between the Drin and the Aous, comprising the area around Epidamnus/Dyrrhachium.
2nd-century AD) recorded the supposed oldest known king in Illyria, Galaurus or Galabrus, a ruler of the Taulantii who reigned in the latter part of the 7th century BC.
[12] Whether or not this account is historically reliable, and despite Polyaenus' interest in the anecdote, it implies the widespread thought throughout antiquity about a significant animosity between the Macedonians and the Illyrians as early as the 7th century BC, if the consensus in modern scholarship in dating the reigning period of Argaeus I is correct.
Their capital was Daorson located in Ošanići near Stolac in Herzegovina, which became the main center of classical Illyrian culture.
Daorson, during the 4th century BC, was surrounded by megalithic, 5 meter high stonewalls, composed out of large trapeze stones blocks.
[31] Pliny (23–79 AD) writes that the people that formed the nucleus of the Illyrian kingdom were 'Illyrians proper' or Illyrii proprie dicti.
