Bardylis or Bardyllis (; ; –358 BC) was an Illyrian king, and the founder of the first attested Illyrian dynasty. During his reign, Bardylis aimed to make Illyria a regional power interfering with Macedon. He united many southern Illyrian tribes under his realm and defeated the Macedonians and Molossians several times, expanding his dominion over upper Macedonia, including Lynkestis, and ruling over Macedon through a puppet king. Before the rise of Macedon, Illyrians were the dominant power in the region. Bardylis also led raids against Epirus, but his soldiers were eventually expelled from th

Cersobleptes (, also found in the form Cersebleptes, Kersebleptēs) was the son of Cotys I, king of the Odrysians in Thrace, on whose death in September 360 BC he inherited the throne. ==Early troubles== From the beginning of his reign, however, Cersobleptes was beset by problems. He inherited a conflict with the Athenians and with the rebel former royal treasurer Miltokythes from his father, and then there appeared two rivals for the throne, Berisades and Amadocus II. Despite the continued able service of Cersobleptes' brother-in-law, the Euboean adventurer Charidemus, Cersobleptes was f

Langarus (; died 335 BC), king of the Agrianians, was a contemporary of Alexander the Great (336–323 BC), with whom he ingratiated himself even before the death of Philip II, previous king of Macedon. Langarus rendered Alexander important services during Alexander's expedition against the Illyrians and Taulantians shortly after his accession, when the Autariatae were preparing to attack him on his march. Langarus invaded their territory, preventing them from carrying their purpose into effect. Alexander conferred on him the most distinguished marks of his favour and promised him his half

He is most known for entering into an alliance with Athens, the Illyrians, and the Paeonians against Philip II of Macedonia in the summer of 356 BC, negotiated by his brother Mononius.

Pleurias (Ancient Greek Πλευρίας; ruled c. 337 – 335 BC) was an Illyrian king. According to some scholars Pleurias was probably king of the Autariatae. An Illyrian king called Pleurias is mentioned only in Diodorus (16.93.6). The name is elsewhere unattested in ancient sources, hence some scholars have identified him with Pleuratos, which is on the contrary a very common name among Illyrians.

Patraus () was king of the ancient kingdom of Paeonia from around 335 until his death in 315 BC. Patraus' relationship with the previous Paeonian king, Lyppeius, is unknown, as are the circumstances surrounding his ascension. Aside from the silver coinage struck in his name, we know nothing for certain about the events of Patraus' reign.

Hebryzelmis (Ancient Greek: Εὐρύζελμις, Ἑβρύζελμις, Ἑβροζέλμης, Εὐρύτελμις) was an Odrysian king of Thrace, attested as ruling in 386/385 BC.

Cothelas (), also known as Gudila (fl. 4th century BC), was a king of the Getae who ruled an area near the Black Sea, between northern Thrace and the Danube. His polity also included the important port of Odessos. Around 341 BC, he concluded a treaty with Macedonian king Philip II, becoming his vassal. This relation was further cemented when Cothelas' daughter, Meda of Odessos, became one of the Macedonian king's wives. The tomb of Cothelas is probably at the Getic burial complex near the present day Bulgarian village of Sveshtari, in North-Eastern Bulgaria.

Lyppeius () was king of the ancient kingdom of Paeonia from 359/8 until his death around 335 BC. He succeeded the first known Paeonian king, Agis, under unknown circumstances and may have been his son, but this is only speculation.
