Amisos was a colony of Miletos that was settled in the 6th century BCE. It grew into a very prosperous town that was easily defended due to being enclosed on two sides by the sea and another by a ravine.
In the 5th century BCE the city became part of the Delian league and was renamed Peiraios after the Athenian Pericles. When Alexander the Great occupied the area, the name returned to Amisos and the city returned to democratic rule.
It eventually became part of the Pontic Kingdom under Mithradates I. The coin below was minted during the time of Mithradates VI.
Not much remains of the ancient city today. Parts were destroyed for a radar base and most of the area is off limits as a military installation. The rest is the modern day city of Samsun.
