Koinon in the context of Illyrian kingdoms

The Bylliones (Ancient Greek: Βυλλίονες) were an Illyrian tribe that lived near the Adriatic coast of southern Illyria (modern Albania), on the lower valley of the Vjosa river, in the hinterland of Apollonia. The Bylliones were firstly attested in epigraphic material from the oracle of Dodona dating back to the 4th century BC, and their koinon was firstly attested in a 3rd-century BC inscription from the same oracle. Their territory was trapezoidal on the right side of the rivers Luftinje and Vjosa, extending in the west to the Mallakastra mountains. The chief city of their koinon was Byllis. Another important centre of their koinon was Klos, an earlier Illyrian settlement later called Nikaia, as an inscription attests. The Bylliones also inhabited in the area of an ancient sanctuary of the eternal fire called Nymphaion.

Through contact with their Greek neighbours, in Hellenistic times the Bylliones acquired a certain degree of Hellenization and bilingualism, especially in the urban centres of their koinon. In Hellenistic times their koinon minted coins as attested by inscriptions reporting their ethnicon in Greek letters. The koinon of the Bylliones survived until Roman Imperial times. In the Roman era, the Bylliones reappear in the late 1st century CE when they are mentioned by Pliny the Elder in the Natural History (c. 79 CE) as one of the "barbarian" tribes which lived in the area of Nymphaeum. The koinon of the Bylliones and the koinon of the Amantes were the most notable Illyrian koina.

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 Thessalian League (Thessalian Aeolic: Κοινὸν τοῦν Πετθαλοῦν, Koinòn toûn Petthaloûn; Attic: Κοινὸν τῶν Θετταλῶν, Koinòn tôn Thettalôn; Ionic and Koine Greek: Κοινὸν τῶν Θεσσαλῶν, Koinòn tôn Thessalôn) was a koinon or loose confederacy of feudal-like poleis and tribes in ancient Thessaly, located in the Thessalian plain in Greece. The seat of the Thessalian League was Larissa.

The Epirote League (Epirote: Κοινὸν Ἀπειρωτᾶν, Koinòn Āpeirōtân; Attic: Κοινὸν Ἠπειρωτῶν, Koinòn Ēpeirōtôn) was an ancient Greek coalition, or koinon, of Epirote tribes.

The League of the Macedonians and Koinon of Macedonia (Ancient Greek: Κοινὸν Μακεδόνων, romanized: Koinòn Makedónōn), was a confederationally-organized commonwealth institution regional state or koinon) consisting of all Macedonian communities united around a monarch. It can be paralleled from the Epirote League, but it seems that the Macedonian koinon had far less power than that of the Epirote Molossians. The capital, or headquarters, of the Macedonian koinon was the city of Beroia.

The Chalcidian League (Greek: Κοινόν τῶν Χαλκιδέων, Koinon tōn Chalkideōn, "League of the Chalcidians"), also referred to as the Olynthians or the Chalcidians in Thrace (Χαλκιδεῖς ἐπί Θρᾴκης, Chalkideis epi Thrakēs) to distinguish them from the Chalcidians in Euboea, was a federal state that existed on the Chalcidice peninsula, on the shores of the northwest Aegean Sea, from around 430 BCE until it was destroyed by Philip II of Macedon in 348 BCE.

The League of the Islanders (Ancient Greek: τὸ κοινὸν τῶν νησιωτῶν, romanized: to koinon tōn nēsiōtōn) or Nesiotic League was a federal league (koinon) of ancient Greek city-states encompassing the Cyclades islands in the Aegean Sea. Organized under the auspices of Antigonus Monophthalmus in c. 314/3 BC, it remained under Antigonid control until c. 287 BC. It then passed under the aegis of the Ptolemaic Kingdom until Ptolemaic control over the central Aegean collapsed and the League was dissolved sometime in the mid-3rd century BC. The Cycladic islands reverted to independence, except for a few that passed under Macedonian control. The league was re-established ("Second Nesiotic League") under the leadership of Rhodes in c. 200 BC, and survived until c. 167 BC.
