Mu'izz al-Din Mahmud was the Zengid Emir of Jazirat Ibn 'Umar (present-day Cizre) from 1208 to 1250/51. One of the last Zengid rulers, Mahmud succeeded his infamous father, Mu'izz al-Din Sanjar Shah, as the ruler of a minor Zengid principality. Contemporary sources described Mahmud's extreme cruelty but otherwise say very little about his reign. He seems to have successfully navigated a complex political landscape and formed an alliance with Badr al-Din Lu'lu', the ruler of Mosul. After Mahmud's death, Badr al-Din Lu'lu' appears to have had his son killed and annexed Jazirat Ibn 'Umar to his own territory.
