In ancient Greece, a metropolis and its apoikiai constituted a form of kinship unity. In Thucydides’ view, at least in his era, particular bonds of kinship connected the Corinthian apoikiai on, or in the vicinity of, the Ambracian Gulf with Corinth itself, and literary tradition endowed Ambracia, Leucas and Anactorion with a special cultural unity. Modern research ranging over political institutions, foreign policy, ideology, economic factors, cults, myths, calendar and burial customs has shown that these poleis regarded themselves as members of a Corinthian colonial family. Initially highly dependent on Corinthian policy during the archaic period, by the end of this period the western apoikiai had admittedly begun to diverge from a Corinthian-centred economy and to move away from Corinthian traditions. Internal social diversification also caused these poleis to move away from Corinthian institutions and habits. Nevertheless, despite various political fluctuations, western Corinthian apoikiai remained within the Corinthian sphere of influence and after Timoleon’s campaign they revived old Corinthian traditions and institutions. Indeed, other Greeks of late classical times regarded the citizens of these poleis as if they were indeed Corinthians. The area remained under Corinthian economic influence throughout Hellenistic times and memories of affinities with and ties to Corinth survived in her apoikiai. Lastly, Hellenistic monarchs and even Augustus himself took advantage of the peculiar Corinthian identity of these apoikiai for their own ends.
