Phraates II was king of the Parthian Empire from 132 BC to 127 BC. He was the son and successor of Mithridates I. Because he was still very young when he came to the throne, his mother Rinnu initially ruled on his behalf. His short reign was mainly marked by his war with the GreekSeleucid Empire, who under king Antiochus VII Sidetes attempted to regain the lands lost to Phraates' father. Initially unsuccessful in the conflict, Phraates managed to gain the upper hand and defeated Antiochus VII's forces, with the Seleucid himself dying in battle or committing suicide. Phraates II afterwards rushed to the east to repel an invasion by nomadic tribes—the Saka and Yuezhi, where he met his end. He was succeeded by his uncle Artabanus I.
Phraates II was born in ; he was the son of Mithridates I, the fifth Parthian king, and a noblewoman named Rinnu, who was the daughter of a Median magnate.
Reign
Phraates succeeded his father in 132 BC; due to still being a minor, his mother ruled with him for a few months. Around this period, Phraates gave Darayan I kingship over the southern Iranian region of Persis. In 130 BC the Parthian empire was attacked from the west. Antiochus VII Sidetes, king of the Seleucid Empire, attacked in the west to reconquer territory lost earlier. After three battles he reclaimed Babylonia. After this he offered a peace, by which he would regain Mesopotamia and large parts of Iran. The Parthian realm would be restricted to its core territories and would pay a heavy tribute. Phraates II could not accept these high demands, so he refused the offer. In the following winter, Antiochus VII quartered himself and his army in Ecbatana, where he completely alienated the local people by forcing them to pay for the upkeep of his soldiers and because, it seems, the soldiers assaulted the locals. Thus, when Phraates II attacked the Seleucid army in its winter quarters, the local population supported him. Antiochus VII was defeated and killed or committed suicide, ending Seleucid rule east of the Euphrates. Phraates II succeeded in capturing Seleucus and Laodice, two of his children who had accompanied their father on campaign. Phraates II later married Laodice and showed Seleucus great favour. He allowed Antiochus VII a royal funeral and later returned the body to Syria in a silver coffin along with Seleucus. Phraates II also released Demetrius II Nicator, who had been held by the Parthians as a hostage for several years, to become king of the Seleucid realm for a second time. Syria, which was now all that was left of the Seleucid empire, lacked military power and Phraates II apparently planned to invade it. However, on the eastern front, various nomadic tribes already infiltrating and usurping the Saka and Tokhari destroyed the Greco-Bactrian Kingdom, penetrated to the borders of the realm in 129 BC, and threatened the Parthian realm. The king had to rush to the eastern front, installing Himeros as governor of Babylon, who quickly became a tyrant. Phraates II marched east, his army including a large force of captured Seleucid soldiers from the army of the late Antiochus VII Sidetes. These soldiers ultimately refused to fight for the Parthian king, and he was defeated and killed in battle.
Coinage and Imperial ideology
Phraates refrained from using the title of "King of Kings" in his coinage, and instead used the title of "great king". Like the rest of the Parthian kings, he used the title of Arsaces on his coinage, which was the name of the first Parthian ruler Arsaces I, which had become a royal honorific among the Parthian monarchs out of admiration for his achievements. Furthermore, he also used the title of Philhellene, which had been introduced during the reign of his father Mithridates I as a political act in order to establish friendly relations with their Greek subjects. An unusual title attested during the reign of Phraates was the title of "King of the Lands", which was rarely used by the Seleucid monarchs. Like his father, Phraates is wearing a Hellenistic diadem, whilst his beard represents the traditional Iranian/Near Eastern custom.
