Maga was a King of Characene a vassal state of the Parthian Empire and important trading city in the Persian Gulf.
[3] Maga may have had possibly one successor, the twenty-third and last ruler Characene, Abinergaios III, who was defeated in 222 by a Persian named Ardašir.
Ardašir had just revolted against his Parthian overlord and was in the process of establishing the Sasanian Empire.
It should also be noted that the king list of Characene is a modern construct and given the sparsity of records could well be inaccurate.
[4] Although a minor and poorly recorded vassal king on the edge of the ancient civilisations, Maga’s rule is of some interest as Characene was the last rump state remaining from the Seleucid Empire.
