Characene
Characene, (Χαρακηνή in Ancient Greek) also known as Mesene (Μεσσήνη) and Meshan, was a kingdom within the Parthian Empire at the head of the Persian Gulf in southern Iraq. Characene's capital was Charax Spasinou (Χάραξ Σπασινού). The city was an important port in trade between Mesopotamia and India, and it provided port facilities for the great city of Susa further up the present-day Karun River.
