When Vespasian in 69 became Roman emperor, Sohaemus was among the first to swear allegiance to him.[1] Under him, Emesa sent the Roman military a regular levy of archers and assisted them in their siege of Jerusalem in 70. In 72, Sohaemus supplied troops to the Roman General Lucius Caesennius Paetus who was the head of the Legio VI Ferrata, in the annexation of the Kingdom of Commagene.
