Osroes I

Coin of Osroes I.

Osroes I (Parthian: 𐭇𐭅𐭎𐭓𐭅, Khusraw) was a prince of Iranian and Greek ancestry. He ruled the Parthian Empire from 109 to 129, with a brief interruption from 116 to 117. He succeeded his brother Pacorus II. For the whole of his reign he contended with the rival King Vologases III based in the East of Parthia.


Osroes I was one of the sons born to Vonones II by a Greek concubine. He invaded Armenia and placed first his nephew Axidares and then his brother Parthamasiris on the Armenian throne.

He deposed Osroes I and put his own puppet ruler, the son of Osroes I, Parthamaspates on the throne. In Mesopotamia Osroes I's brother Mithridates IV and his son Sanatruces II took the diadem and fought against the Romans, but Trajan marched southward to the Persian Gulf, defeated them, and declared Mesopotamia a new province of the empire. Later in 116, he crossed the Khuzestan Mountains into Persia and captured the great city of Susa.

Following the death of Trajan and Roman withdrawal from the area, Osroes I easily defeated Parthamaspates and reclaimed the Persian throne. Hadrian acknowledged this fait accompli, recognized Osroes I, Parthamaspates King of Osroene, and returned Osroes I's daughter who had been taken prisoner by Trajan.
