The consequence of this battle was the collapse of the last Hellenistic kingdom (the Ptolemeans of Egypt) and the beginning of the Roman Age under the monocracy (autocracy) of the victor, Octavian Augustus. In memory of his glorious victory, Octavian founded Nicopolis (the City of Victory) to the southernmost end of Epirus by forcing the inhabitants from around twenty cities of Etolia, Acarnania and Epirus to resettle there, in addition to bringing new settlers from Italy.
Endowed with exceptional privileges and tax exemptions, as a "free city", Nicopolis did not take long to develop into a large thriving city. Its harbours (Komaros and Vathy), its excellent geographical position at a junction between Epirus and Acarnania as well as between Greece and Italy, the re-establishment of the Aktia Games as an "equivalent to the Olympic gymnastic games along with musical competitions, horse races that were held every four full years", turned it into a pole of attraction in the wider Mediterranean area. 'Nicopolis is populous, and its numbers are increasing daily', mentions Strabo. Its inhabitance continued on into the Byzantine times as well. http://www.visit-preveza.com/el/nikopoli
