It was situated on the Eurymedon River about 10 miles (16 km) inland from the Mediterranean Sea; it shared a border with, and was hostile to, Side. According to later tradition, the (originally non-Greek) city was founded around 1000 B.C. by Greeks who may have come from Argos. The wide range of its coinage throughout the ancient world indicates that, in the 5th century B.C., Aspendus had become the most important city in Pamphylia. At that time the Eurymedon River was navigable as far as Aspendus, and the city derived great wealth from a trade in salt, oil, and wool. In 333 B.C.

In 190 B.C. the city surrendered to the Romans, who later pillaged it of its artistic treasures. Toward the end of the Roman period the city began a decline that continued throughout Byzantine times.
