Polieum

Polieum (later known by the more famous name of Sinis) is an Ionian colony founded in the territory of the Oenotrians by colonists fleeing Colophon for fear of conquest by King Gyges of Lydia. It is a prosperous city located on fertile lands and thought to have lived in luxury and decadence similar to Sybaris, but this wealth, combined with its Ionian origins would eventually lead to the Achaean colonies of Sybaris, Kroton and Metapontum forming a coalition to destroy it completely at some point between 550 BCE and 510 BCE. Its empty lands would later be host to a dispute between Taras and Thurii, which would be won by Taras, who would establish a new colony of Heraclea on what once was Polieum.
