The Parthians captured Edessa and installed Wa'el (son of Sahru) as puppet king.[1][2] Ma'nu VIII (son of Ma'nu VII), the legitimate king, was forced to flee to the Romans.[3]
Wa'el would rule Edessa/Osroene as a Parthian subject from 163 to 165, when the Romans regained possession of the city and reinstalled Ma'nu VIII on the throne.[1][2] During his short tenure, Wa'el issued coins with the portrait of the Parthian king.[2]
