they would have been either the Enchelei, whose realm was centered at that time in the area of Lake Lychnidus, or the Taulantii, who were based farther west, in the coastal area within and around Epidamnos and Apollonia. The Illyrian raids against the Argeads who were based at Aegae indicate that Illyrian attacks also involved the Upper Macedonian regions of Lynkestis, Orestis and Eordaea, Elimea, and Tymphaea, as they were located between Illyrian territory and Argead lands. Classical period The Taulantii continued to play an important role in Illyrian history between the 5th and 4th–3rd centuries BC, and in particular in the history of Epidamnos-Dyrrhachion, not only as its neighbors but also as part of its population. Although the Epidamnians established the figure of a trade magistrate (poletes) to avoid the influence of the native people surrounding Epidamnos, it wasn't enough to prevent intervention of neighboring Illyrians in the internal affairs of the city. The constitution of Epidamnos was initially oligarchic, and many inhabitants were not citizens. In 435 BC, the city suffered an intence civil war undertaken between the democratic faction and the aristocratic faction. After the democrats had seized power, the exiled oligarchs joined with the neighboring Taulantii to retake the city. The Illyrians besieged the city in strength, and through the occupation of the surrounding region, they caused much damage to the economy of the city. The social crisis caused the intervention of the two mother cities: Corinth on the side of the democrats and Corcyra on the side of the aristocrats and native Illyrians. Corcyra won the naval battle against Corinth, taking Epidamnos and driving out the demos. At the end of the naval battle Athens, the leader of the Delian League, took sides with the Corcyreans, as Corinth was already allied with Sparta within the Peloponnesian League. This was the pretext for the Peloponnesian War as reported by Thucydides. In the well attested historical period, the Taulantian kingdom seems to have reached its apex during Glaukias' rule, in the years between 335 BC and 295 BC. Glaucias had entered into an alliance and joined the cause of another Illyrian dynast, Cleitus son of Bardylis, who revolted against Alexander the Great, in the siege of Pelium (335 BC). However, they were both defeated and Cleitus was forced to take refuge within the Taulantian territories. Unlike the Illyrians of Cleitus, king Glaukias and the Taulantii had not
