Perinthus was founded by colonists from the island of
Samos in 602 BC. It was particularly renowned for
its obstinate defence against
Philip II of Macedon. At that time it appears to have been a more important and flourishing town even than
Byzantium and being both a harbour and a point at which several main roads met, it was the seat of extensive commerce. This circumstance explains the reason why so many of its coins are still extant from which we learn that large and celebrated festivals were held here. Perinthus was renamed to Heraclea in 286 AD during the reign of the Roman emperor
Diocletian. It was sometimes called Heraclea Thraciae and Heraclea Perinthus.
Septimius Severus (r. 193–211) twice granted the city the prestigious title of
neokoros and gave it permission to hold crown festivals in his honor, in recognition of its support during his conflict with
Pescennius Niger, a rival claimant to the Roman throne.
Justinian restored the old imperial palace, and the
aqueducts of the city. The inscriptions from Perinthus and the literary testimonia on the city have been collected by Mustafa Hamdi Sayar. == Cityscape ==
