Bardylis

Under the reign of Philip II (359–336 BC), the ancient kingdom of Macedonia, initially at the periphery of classical Greek affairs, came to dominate Ancient Greece in the span of less than 25 years, largely thanks to the character and policies of its king. In addition to utilising effective diplomacy and marriage alliances to achieve his political aims, Philip II was responsible for reforming the ancient Macedonian army into an effective fighting force. The Macedonian phalanx became the hallmark of the Macedonian army during his reign and the subsequent Hellenistic period. His army and engineers also made extensive use of siege engines. Chief among Philip's Thracian enemies was the ruler Kersebleptes, who may have coordinated a temporary alliance with Athens. In a series of campaigns stretching from 356 to 340 BC, Philip II managed to ultimately subjugate Kersebleptes as a tributary vassal, conquering much of Thrace in the process. Philip II also fought against the Illyrian king Bardylis, who threatened Macedonia proper, and against Grabos II and Pleuratus in Illyria (centred in modern-day Albania). In his newly conquered territories, he founded new cities such as Philippi, Philippopolis (modern Plovdiv, Bulgaria), Herakleia Sintike (Pirin Macedonia, Bulgaria), and Herakleia Lynkestis (modern Bitola, North Macedonia).

Philip II eventually campaigned against the city-state of Athens and her allies in the Aegean region, as well as Thebes after the decline of its hegemony in mainland Greece. In the defence of the Amphictyonic League of Delphi and in conjunction with the Thessalian League, Macedonia became a key player in the Third Sacred War (356–346 BC), defeating the Phocians, commanded by Onomarchus, at the Battle of Crocus Field in 352 BC. While poised to launch a direct assault on Athens in 346 BC, the Macedonian king was met with an Athenian embassy that arranged the Peace of Philocrates. As a result, Macedonia and Athens became allies, yet Athens was forced to relinquish its claims to the city of Amphipolis (in modern-day Central Macedonia).

The Illyrian kingdom was an Illyrian political entity that existed on the western part of the Balkan Peninsula in ancient times. Regardless of the number of the alternately ruling dynasties, of their tribal affiliation, and of the actual extension of their kingdom, it represented an alliance of Illyrian tribes that united under the rulership of a single leader, expressly referred to as "King of the Illyrians" in ancient historical records (whether in Ancient Greek or in Latin). The monarchic superstructure of the Illyrian state coexisted with the Illyrian tribal communities and the republican system of the Illyrian koina.

The Enchele's polity was the earliest to emerge among Illyrians. The earliest known Illyrian king – Bardylis – emerged in southern Illyria around 400 BC, most likely centered in Dassaretis, a region along Lake Ohrid and east to the Prespa Lakes, located on the border between Macedon and Epirus. He 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 and Lynkestis and subjugating Macedon for several decades until he was decisively defeated by Philip II of Macedon. Before the Rise of Macedon Illyrians were the dominant power in the area. The kingdom of the Taulantii on the south-eastern coast of the Adriatic evidently reached its apex under Glaukias' rule and dominated southern Illyrian affairs in the late 4th century BC, exerting great influence on the Epirote state through the close ties with the Molossian king Pyrrhus.

The kingdom of Macedonia was an ancient state in what is now the Macedonian region of northern Greece, founded in the mid-7th century BC during the period of Archaic Greece and lasting until the mid-2nd century BC. Led first by the Argead dynasty of kings, Macedonia became a vassal state of the Achaemenid Empire of ancient Persia during the reigns of Amyntas I of Macedon (r. 547 – 498 BC) and his son Alexander I of Macedon (r. 498 – 454 BC). The period of Achaemenid Macedonia came to an end in roughly 479 BC with the ultimate Greek victory against the second Persian invasion of Greece led by Xerxes I and the withdrawal of Persian forces from the European mainland.

During the age of Classical Greece, Perdiccas II of Macedon (r. 454 – 413 BC) became directly involved in the Peloponnesian War (431–404 BC) between Classical Athens and Sparta, shifting his alliance from one city-state to another while attempting to retain Macedonian control over the Chalcidice peninsula. His reign was also marked by conflict and temporary alliances with the Thracian ruler Sitalces of the Odrysian Kingdom. He eventually made peace with Athens, thus forming an alliance between the two that carried over into the reign of Archelaus I of Macedon (r. 413 – 399 BC). His reign brought peace, stability, and financial security to the Macedonian realm, yet his little-understood assassination (perhaps by a royal page) left the kingdom in peril and conflict. The turbulent reign of Amyntas III of Macedon (r. 393 – 370 BC) witnessed devastating invasions by both the Illyrian ruler Bardylis of the Dardani and the Chalcidian city-state of Olynthos, both of which were defeated with the aid of foreign powers, the city-states of Thessaly and Sparta, respectively. Alexander II (r. 370 – 368 BC) invaded Thessaly but failed to hold Larissa, which was captured by Pelopidas of Thebes, who made peace with Macedonia on condition that they surrender noble hostages, including the future king Philip II of Macedon (r. 359 – 336 BC).

Pelion, also Pellion or Pelium (Ancient Greek: Πήλιον, Πέλλιον or Πήλεον, Latin: Pelion, Pelium or Pellium) was an ancient fortified settlement traditionally located in Illyria, near the Tsangon Pass, on the border with Macedonia. Pelion is generally placed in eastern Dassaretis very close to the historical border with Macedonia, however its precise location is uncertain and various theories have been proposed for the site of the settlement.

Founded either by the Illyrian king Bardylis or by the Macedonian king Philip II, the fortified site of Pelion had been controlled in different periods by the Illyrian kingdom, the Macedonian kingdom, and Rome. Under the Roman rule Pelion was placed in the autonomous administrative unit of Dassaretis, in Epirus Nova and in the Prefecture of Illyricum.

Glaucias (Ancient Greek: Γλαυκίας; ruled c. 335 – c. 295 BC) was a ruler of the Taulantian kingdom, situated in modern day Albania, which dominated southern Illyrian affairs in the second half of the 4th century BC. Glaucias is first mentioned as bringing a considerable force to the assistance of Bardylis' son Cleitus, an Illyrian prince who revolted against Alexander the Great, in the battle of Pelium 335 BC. They were, however, both defeated, and Cleitus was forced to take refuge within the Taulantian territories, whither Alexander did not pursue him, his attention being called elsewhere by the news of the revolt of Thebes.

We next hear of Glaucias, nearly 20 years later, as affording an asylum to the infant Pyrrhus, when his father Aeacides was driven out of Epirus; Glaucias' wife Beroea belonged to the Molossian Aeacidae. By this measure he gave offence to Cassander, who sought to gain possession of Epirus for himself, and who in vain offered Glaucias 200 talents to give up the child.

During classical antiquity, Albania was home to several Illyrian tribes such as the Albanoi, Ardiaei, Bylliones, Dassaretii, Enchele, Labeatae, Taulantii, Parthini, Penestae, Amantes, and many others, but also Bryges and Epirote tribes, as well as several Greek colonies established on the Illyrian coast in cooperation with the local Illyrians, notably Epidamnos-Dyrrhachium and Apollonia.

The Enchele's polity was the earliest to emerge and centered in Albania. Also the earliest known Illyrian king, Bardylis, emerged in what is now Albania around 400 BC, aiming 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 and Lynkestis. Before the Rise of Macedon Illyrians were the dominant power in the region. The kingdom of the Taulantii under Glaukias' rule was based in central Albania and dominated southern Illyrian affairs in the late 4th century BC, exerting great influence on the Epirote state through the close ties with the Molossian king Pyrrhus. Under the Ardiaei the greatest known Illyrian kingdom emerged in the 3rd century BC encompassing also northern Albania in its core territory. It became a formidable power both on land and sea by assembling a great army and fleet, and directly ruling over a large area made up of different Illyrian tribes and cities that stretched from the Neretva River in the north to the borders of Epirus in the south, while its influence extended throughout Epirus and down into Acarnania. The dominant power of the Illyrian kingdom in the region ceased after the Illyrian defeat in the Illyro-Roman Wars (229–168 BC). The last known "King of the Illyrians" was Gentius, of the Labeatae tribe.

Cleitus (Ancient Greek: Κλεῖτος; ruled c. 356–335 BC) was an Illyrian ruler, the son of the King Bardylis and the father of Bardylis II.

Cleitus was the mastermind behind the well-structured Illyrian Revolt of 335 BC. Cleitus entered into an agreement with the Taulantii State under Glaucias and the Autariatae State under Pleurias. Cleitus had captured and garrisoned the city of Pelion and waited for Glaucias' troops to arrive. However, Alexander arrived on the scene first and blockaded Cleitus within the city walls. Glaucias came to Cleitus' aid, and the Macedonians were forced to retreat. Alexander came back with more equipment and supplies and skillfully drove Glaucias' army from the surrounding heights, preventing Cleitus from engaging with Glaucias.
