Cities in Thrace and Asia Minor sometimes formed homonoia (alliances) with other cities. The competition for prestige and rivalry between cities in the East was intense. Alliances could enhance a city's status by aligning either with many cities or with particularly important ones. Homonoia was part of civic "foreign policy" and might have involved the exchange of delegates and joint celebrations and sacrifices. At least 87 cities issued homonoia coins celebrating their alliances.
