Knowledge 1: Mithridates II of Commagene
Mithridates II Antiochus Epiphanes Philorhomaeus Philhellen Monocrites (died 20 BC), also known as Mithridates II of Commagene, was a man of Armenian and Greek descent who lived in the 1st century BC.He was a prince of Commagene and one of the sons of King Antiochus I Theos of Commagene and Queen Isias Philostorgos of Commagene.When his father died in 38 BC, he succeeded his father and reigned until his death.According to Plutarch, he was an ally of the Roman triumvir Mark Antony.In 31 BC, Mithridates personally led his forces to Actium in Greece in support of Antony in the war against Caesar Octavian, the future Roman emperor Augustus.After the defeat of Antony, however, Mithridates became a loyal ally to Augustus.Nevertheless, Augustus forced Mithridates to hand over a village in Commagene called Zeugma, which was a major crossing point of the Euphrates River, to the Roman province of Syria.To show his support for Augustus, Mithridates dropped the title "Philhellenfriend of the Greeks") from his Aulic titulature and adopted the title "Philorhomaeusfriend of the Romans") instead.Both titles were derived from the Commagenean royal cult that Mithridates' father had founded, and in which Mithridates played an important role.His other title "Monocrites" is an otherwise unattested title and was most likely a judicial function within the royal administration and a sign of his high social standing.Mithridates had a brother, Antiochus II of Commagene, who was also a prince of the kingdom.In 29 BC, Antiochus was summoned to Rome and executed by Roman emperor Augustus, because Antiochus had caused the assassination of an ambassador whom Mithridates had sent to Rome.According to an inscription found in the Turkish village of Sofraz on a funerary altar of a prominent and wealthy local family, dating to around the mid-1st century, the wife of Mithridates was a Greek woman called Laodice.The altar inscribes the names of seven generations of family members, including the names of Mithridates, of his father and of his wife.When Mithridates died in 20 BC, his son by Laodice, Mithridates III of Commagene, succeeded him.
