[1] Their territory included the entire region between the rivers Asamus and Eordaicus (whose union forms the Apsus), the plateau of Korça locked by the fortress of Pelion and, towards the north it extended to Lake Lychnidus up to the Black Drin.
[3] One of the most important settlements in their territory was established at Selcë e Poshtme near the western shore of Lake Lychnidus, where the Illyrian Royal Tombs were built.
[10][11] During a campaign in Illyria in 335 BC, Alexander the Great undertook a victorious siege at Pelion, in Dassaretis, against Illyrians who revolted under the leadership of Cleitus, son of Bardylis, with the aid of Glaucias, king of the Taulantii.
It is related to Illyrian personal names Dazos and Dassius and is also reflected in the toponym of Daksa island and the river Ardaxanos, which is mentioned by Polybius (2nd century BC) in the hinterland of modern Durrës and Lezhë.
[27] According to a mythological tradition reported by Appian (2nd century AD), the Dassaretii were among the South-Illyrian tribes that took their names from the first generation of the descendants of Illyrius, the eponymous ancestor of all the Illyrian peoples.
[31][32][33] The Dassaretii were located between the tribes of Parthini (who dwelled in the Shkumbin valley) and Atintanes (who inhabited in the mountain ranges between Asamus and Aous rivers).
The extent of the territory of Dassaretii seems to have been considerable, since it included the entire region between the rivers Asamus and Eordaicus (whose union forms the Apsus), the plateau of Korça locked by the fortress of Pelion and, towards the north it extended to Lake Lychnidus up to the city of the same name.
[37] Livy (1st century BC) reports that following the victory of 167, the Roman Senate decided to give freedom to "Issenses et Taulantios, Dassaretiorum Pirustas, Rhizonitas, Olciniatas", rewarded because they abandoned the Illyrian kingdom of Gentius a little before his defeat.
For a similar reason Daorsi too gained immunitas, while half of the tax had to be paid by "Scodrensibus et Dassarensibus et Selepitanis ceterisque Illyriis" ("the inhabitants of Scodra, Dassarenses and Seleptani, as well as by other Illyrians").
[41][42][24] The settlement of Hija e Korbit in the Korça plain at the Devoll river (ancient Eordaicus) had been probably one of the relevant commercial and military sites of the Illyrian Dassaretii.
[47] It has been suggested that the zone located to the south and west of the Dassareti, Parthini and Taulanti, before reaching the Chaones and Atintanes, was a mixed area generally considered as a part of Illyria, however it was a cultural extension of Greek-speaking Epirus.
In particular, a 3rd-century BC silvered bronze belt buckle, found inside the Illyrian Tombs of Selça e Poshtme near the western shore of Lake Lychnidus in Dassaretan territory, depicts a scene of warriors and horsemen in combat, with a giant serpent as a protector totem of one of the horsemen; a very similar belt was found also in the necropolis of Gostilj near the Lake Scutari in the territory of the Labeatae, indicating a common hero-cult practice in those regions.
Modern scholars suggest that the iconographic representation of the same mythological event includes the Illyrian cults of the serpent, of Cadmus, and of the horseman, the latter being a common Paleo-Balkan hero.
In later Roman times, the cult of Diana Candaviensis, which has been interpreted as "Artemis the Huntress", was practiced up to the region north of Lake Shkodra (ancient lacus labeatis), including also the territory of the Docleatae.
It seems that the weakening of the kingdom of Enchelae resulted in their assimilation and inclusion into a newly established Illyrian realm at the latest in the 6th–5th centuries BC, marking the arising of the Dassaretii, who appear to have replaced the Enchelei in the lakeland area (Ohrid and Prespa).
[7][8] According to a historical reconstruction, Bardylis founded a powerful Illyrian dynasty among the Dassaretii in the 5th century BC,[55][56][57][58] and established a realm centered in their territory that comprised the area along Lychnidus and east to the Prespa Lakes, which was called "Dassaretis" later in Roman times.
[63] Bardylis' expansion in Upper Macedonia and Molossis, and his son Cleitus' revolt at Pelion in Dassaretis against Alexander the Great make this localization of the core of their realm even more plausible.
[34] The site of Selcë was in the past a flourishing economical centre more developed than the surroundings because it occupied a predominant position inside the region currently called Mokër, and because it controlled the road which led from the Adriatic coasts of Illyria to Macedonia.
[73] The retreat to the north and in later times the destruction of the Illyrian kingdom highlighted numerous communities in southern Illyria – including the Dassaretii – that were organized in koina, as evidenced by historical sources, coins and epigraphic material.
[74] The following is a list of the members of Bardylis' Illyrian dynasty recorded as such in ancient sources, whose realm was centered in the territory of the Dassaretii as claimed by a number of modern scholars:[9] Grabos I (fl.
2nd century BC) describes peoples of Illyria, like the Dassaretae and the Ardiaei, using the term ethnos, with the meaning of "tribes" within wider national units.
Including the valleys of Osum and Devoll rivers, stretching to the east into the Korçë Plain, and comprising the area around lake Ohrid, the Illyrian Dassaretan region was rich in natural resources and was located in a strategic geographical position that aroused the political wishes of the neighbours and the interest of the Greek merchants.
An example is the account about the Roman consul Sulpicius, who during the Second Macedonian War in 199 BC, passed through the territory of the Dasaretii and supplied his army with the products offered by that region, without the resistance of the locals.
