Sinharib or Sanharib, Syriac: ܣܢܚܪܝܒ, according to the Hagiography of Mar Behnam was an Assyrian client king of Nineveh in the fourth century AD. Nineveh was at the time within the Asōristān province of the Sasanian Empire. Much like Julian the Apostate of the Roman Empire, Sanharib disliked Christianity and tried to persuade his son Behnam to reject Christianity. Although greatly influenced by the Persian Zoroastrian religion at first, he later became Christian.
