Nikopolis, Epirus was founded as a "free" Greek city after the battle of Actium, 31 B.C. It grew very quickly into a big city, its population of Greek citizens gathered by force from twenty cities of Aetolia, Acarnania and Epirus, also Corinth, and even Italy. Instantly Nikopolis became a pole of attraction for the Mediterranean area, because of citizen's connections throughout the region, its excellent location, three ports, and the Aktia (games held every five years).
