In 163, the Parthians installed Wa'el, son of Sahru, as ruler of Edessa and Osroene, displacing the pro-Roman Ma'nu VIII. Wa'el issued coins bearing the Parthian king's portrait, signalling a shift in allegiance. Ma'nu VIII fled to Roman territory, prompting Roman intervention to reassert influence over the strategically important city.
In 165, Roman forces under Emperor Lucius Verus besieged Parthian-held Edessa. During the siege, the city's own citizens killed the Parthian garrison and opened the gates to the Roman army. Roman troops entered the city, and Ma'nu VIII was reinstated as ruler of Edessa and Osroene, receiving the honorary title Philorhomaios, meaning Friend of the Romans.
Following the siege, Edessa and Osroene formally renounced their allegiance to the Parthian Empire and re-entered the Roman sphere of influence. The reinstatement of Ma'nu VIII as a client ruler cemented Roman dominance over the region and reversed the Parthian political gains made in 163.
