Noun
Meaning

An association or federation of distinct city-states with shared political institutions and citizenship.
Examples
In addition, the koinon financed new building projects at Ilion, for example a new theatre c. 306 and the expansion of the sanctuary and temple of Athena Ilias in the 3rd century, in order to make the city a suitable venue for such a large festival.
The primary purpose of the koinon was to organize the annual Panathenaia festival which was held at the sanctuary of Athena Ilias.
The governing body of the koinon was the synedrion on which each city was represented by two delegates.
This system of equal (rather than proportional) representation ensured that no one city could politically dominate the koinon.
