The first mention of Achilleion is as a fortified settlement from which Mytilene conducted its attacks on Athenian controlled Sigeion to the north in the early 6th century BCE. It is not clear whether Achilleion had been settled earlier, but the ceramic record also begins at this point, suggesting that it had not. Recent excavations have established that the walls of the settlement also date to the first half of the 6th century BCE, further corroborating the literary accounts of Herodotus and Strabo regarding its origins. Achilleion remained under Mytilenaean control until Athens brought an end to the Mytilenean revolt in 427 BCE and took over all the so-called Actaean cities in the Troad. Achilleion appears in the Athenian tribute lists for 425/4 and 422/1 BCE, indicating that it had joined the Delian League. The legend ("ACH") which some bronze coins found in this region bear is thought to refer to Ach (illeion) and suggest that c. 350 - 300 BCE the city minted its own coins. King Lysimachus synoecized Ilion with many surrounding communities including Achilleion during his reign (306 - 281 BCE), effectively ending Achilleion's political independence. The testimony of Demetrius of Scepsis, who hailed from a nearby town in the Troad, indicates that there was still a hamlet known as Achilleion on the site in the mid-2nd century BCE. It is to around this time that the latest ceramic finds from Achilleion date, suggesting that the site became uninhabited soon afterwards.
