Bardylis, a Dardanian chieftain, created a kingdom which turned Illyria into a formidable local power in the 4th century BC. The main cities of this kingdom were Scodra (present-day Shkodra, Albania) and Rhizon (present-day Risan, Montenegro). In 359 BC, King Perdiccas III of Macedon was killed by attacking Illyrians.
