The early settlements of Notion dates back to the 6th century BC. During the Peloponnasian Wars- the dreadful wars between Helens during the years of 431-404 BC, Notion played a significant role, serving as the naval base of Athenians. The numerous wars between Spartans& Athenians were to colonize the coastal towns of Anatolia and ended with the loss of Athenians. The harbor of Notion was considered as alternative to the harbor of Ephesus but did not become as popular as Ephesus, during the time. In 334 BC, the city was invaded by Alexander the Great. Following his death, Lysimakhos, the founder of the New Ephesus, deported most of the inhabitants to Ephesus and Lebedus. Part of the remaining population emigrated to Notion, which hence forth was called "Neo Colophon" . During the Roman times, the city entered upon a new era of prosperity both in commerce and social life. Temples, agoras, and bouleuterions, buildings housing social activities were built throughout the period. Towards the end of the Roman era, the harbor of Notion lost its prior importance as it was getting filled. During the Byzantine era, Notion was within the borders of Asian Province and remained as the bishopric until the Middle Ages.
