Antiochus III of Commagene

Antiochus III Epiphanes (Greek: Ἀντίοχος ὀ Ἐπιφανής, flourished 1st century BC and 1st century AD) was the ruler of the Kingdom of Commagene from 12 BC to 17 AD. He was the son and successor of King Mithridates III of Commagene and Iotapa, and of mixed Iranian, Armenian, Greek and Median descent – the last through his mother. His parents were first cousins.

When Antiochus died in 17 AD, his death created major issues for the kingdom, which was in political turmoil at the time. The reasons for this situation are unclear, but it may have been the consequence of his children, Antiochus and Iotapa, being too young to succeed their father. This may have meant that there was no effective authority to prevent civil unrest and unite the citizens of Commagene.
