Bardhyllus was an Illyrian king who ruled from 385 to 358 BC and founded the Bardhyllus Dynasty. The name translates to "white star" from Albanianbardhë (white) and yll (star).
Initially a Dardanian coalman, he claimed the throne of the first Illrian king, Sirra. He took back all Illyrian land from the Macedonians, defeating four Macedonian kings and was very popular with the Illyrian people when he divided up his spoils. Under his reign, the Illyrians nearly succeeded in destroying the kingdom of Macedon, but in 359 BC, Philip the Great conquered Illyria. Bardylis made peace with Philip before dying in 358 BC at the age of 90.
The Army had been nearly destroyed in the recent battle with Bardylis, the Illyrian, Macedonia was probably in horrible shape, Philip faced the prospect of war with two pretenders to the throne, and his adjacent enemies, seeing Macedonia weakened, were ready to pounce.
Philip was attempting to delay Bardylis though his marriage to Audata to not stop him.
Bardylis was very old when he defeated Perdikkas and might have lost his urge to wage war.19 He was not planning on such a monumental defeat of his foe and thus was not prepared to venture into the interior of Macedonia.
