Xérxēs (Ξέρξης) is the Greek and Latin (Xerxes, Xerses) transliteration of the Old Iranian Xšaya-ṛšā ("ruling over heroes"), a popular name amongst the rulers of the Persian Achaemenid Empire.^[1]

Xerxes belonged to the Orontid dynasty of Iranian^[2] and Armenian^[3] origin. His father was Arsames I, who ruled Sophene, Commagene and possibly Armenia.^[4] Xerxes succeeded his father as the ruler of Sophene and Commagene in 228 BC, while his brother Orontes IV ruled Armenia. In 223 BC, several Seleucid satraps rebelled against King Antiochus III, including Artabazanes (Upper Media), Molon (Lower Media), Alexander (Persis), and Achaeus (Asia Minor). By 220 BC Antiochus had put down most of the rebellions; however, Achaeus was not defeated until 213 BC.

These rebellions help explain Antiochus' subsequent aggressive policy toward his satrap Xerxes. By 212 BC, Antiochus III had invaded the domain of Xerxes and defeated him after laying siege to the city of Arsamosata.^[5] Shortly afterwards Antiochus III arranged for Xerxes to marry his sister, Antiochis.^[6] However, within the same year she arranged to have her new husband assassinated, thinking that her brother would then be able to take control of Sophene. Whether Xerxes still ruled Commagene by the time of his assassination is not known.

His Persianism meanwhile was a constructed identity with contemporaneous aims and not a case of real 'continuity'. The historical roots of the Commagenian dynasty – whether Persian, Armenian, Macedonian or a mixture of all that – have little relevance for understanding Antiochos' dynastic policy, which can best be understood in the context of its own time rather than from the Persian 'traditions' that Antiochos presents to us but are not attested in Commagene before his reign.[...]The dual rows of stelae on both the east and west terrace (fg 2) represent Antiochos' progonoi in respectively the male and female line: the first traces his ancestry through Commagenian kings and Armenian satraps to the Achaemenid dynasty (EN I, 1–15; WS I, 1–15);[...]As regards the historicity of Antiochos' Achaemenid ancestry: a marital bond between the Orontid rulers of Armenia and the Achaemenid dynasty has indeed been attested, and is referred to on Nemrud Dağ by the mentioning of Rhodogune, daughter of Artaxerxes II, on stele 6, which is dedicated to the first of the Armenian satraps, Aroandas/Orontes I (Artaxerxes II precedes him on stele 5): "Aroandas son of Artasuras, who married Queen Rhodogune, daughter of Artaxerxes". A weak link, however, appears in the form of the first Commagenian ruler, Ptolemaios, who is supposed to be the connection between on the one hand the rulers of Commagene and on the other hand the Orontid kings of Armenia. The Armenian Orontids controlled Commagene as part of their holdings until it became a separate administrative unit or kingdom within the Seleucid Empire, perhaps in the reign of Antiochos III the Great. Next to nothing, however, is known about this Ptolemaios, who ruled as an independent Seleucid client from ca. 163 or 150 BCE. While the link between the Achaemenids and the Orontids of Armenia is indicated by the mentioning of Rhodogune, a connection between Ptolemaios and the Armenian Orontids is conspicuously absent, though a marital link is not in itself impossible.
