Context: Vespasian (  ;  17 November AD 9  23 June AD 79) was Roman emperor from AD 69 to AD 79. Vespasian founded the Flavian dynasty that ruled the Empire for twenty-seven years. Vespasian was from an equestrian family that rose into the senatorial rank under the JulioClaudian emperors. Although he fulfilled the standard succession of public offices and held the consulship in AD 51, Vespasian's renown came from his military success: he was legate of Legio II "Augusta" during the Roman invasion of Britain in 43 and subjugated Judaea during the Jewish rebellion of 66., The Parthian Empire (247 BC  224 AD), also known as the Arsacid Empire, was a major Iranian political and cultural power in ancient Iran and Iraq. Its latter name comes from Arsaces I of Parthia who, as leader of the Parni tribe, founded it in the mid-3rd century BC when he conquered the region of Parthia in Iran's northeast, then a satrapy (province) in rebellion against the Seleucid Empire. Mithridates I of Parthia (r. "c". 171138 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to eastern Iran. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han Empire of China, became a center of trade and commerce., Orodes II of Parthia ( Persian :    ) , ( also called Hyrodes Anaridius ) was the king of the Parthian Empire from 57 BC to 37 BC. Orodes was a son of Phraates III , whom he murdered in 57 BC , assisted by his brother Mithridates . He married a Greek Princess from the Kingdom of Commagene , called Laodice who was a daughter of King Antiochus I Theos of Commagene and Queen Isias Philostorgos of Commagene ., The Seleucid Empire ("Basileía tn Seleukidn") was a Hellenistic state ruled by the Seleucid dynasty, which existed from 312 BC to 63 BC; it was founded by Seleucus I Nicator following the division of the Macedonian empire vastly expanded by Alexander the Great. Seleucus received Babylonia and, from there, expanded his dominions to include much of Alexander's near eastern territories. At the height of its power, it included central Anatolia, Persia, the Levant, Mesopotamia, and what is now Kuwait, Afghanistan, and parts of Pakistan and Turkmenistan., Antiochus IV Epiphanes ("Antíochos D' ho Epiphans", "God Manifest"; c. 215 BC  164 BC) was a Hellenistic Greek king of the Seleucid Empire from 175 BC until his death in 164 BC. He was a son of King Antiochus III the Great. His original name was Mithradates (alternative form "Mithridates"); he assumed the name Antiochus after he ascended the throne., The Kingdom of Commagene was an ancient Armenian kingdom of the Hellenistic period, located in and around the ancient city of Samosata, which served as its capital. The Iron Age name of Samosata, Kummuh, probably gives its name to Commagene. Commagene has been characterized as a "buffer state" between Armenia, Parthia, Syria, and Rome; culturally, it seems to have been correspondingly mixed. The kings of the Kingdom of Commagene claimed descent from Orontes with Darius I of Persia as their ancestor, by his marriage to Rodogoune, daughter of Artaxerxes II who had a family descent from king Darius I. The territory of Commagene corresponds roughly to the modern Turkish provinces of Adyaman and northern Antep.
Little is known of the region of Commagene prior to the beginning of the 2nd century BC. However, it seems that, from what little evidence remains, Commagene formed part of a larger state that also included the Kingdom of Sophene. This control lasted until , when the local satrap, Ptolemaeus of Commagene, established himself as independent ruler following the death of the Seleucid king, Antiochus IV Epiphanes. The Kingdom of Commagene maintained its independence until 17 AD, when it was made a Roman province by Emperor Tiberius. It reemerged as an independent kingdom when Antiochus IV of Commagene was reinstated to the throne by order of Caligula, then deprived of it by that same emperor, then restored to it a couple of years later by his successor, Claudius. The reemergent state lasted until 72 AD, when the Emperor Vespasian finally and definitively made it part of the Roman Empire.
One of the kingdom's most lasting visible remains is the archaeological site on Mount Nemrut, a sanctuary dedicated by King Antiochus Theos to a number of syncretistic Graeco-Iranian deities as well as to himself and the deified land of Commagene. It is now a World Heritage Site., Arsaces I ("Arshak") was the founder of the Arsacid dynasty of Parthia, and after whom all 30+ monarchs of the Arsacid empire officially named themselves. A celebrated descent from antiquity (the Bagratid "line") begins with Arsaces. Arsaces or Ashk has also given name to the city of Ashkabad., In Ancient Rome, a province (Latin: "provincia", pl. "provinciae") was the basic, and, until the Tetrarchy (293 AD), largest territorial and administrative unit of the empire's territorial possessions outside of Italy. The word "province" in modern English has its origins in the term used by the Romans., Subject: orodes ii of parthia, Relation: noble_family, Options: (A) arsacid dynasty of parthia (B) flavian dynasty (C) seleucid empire (D) tetrarchy
