Abūʾl Nasr Manṣūr ibn Luʾluʾ, also known by his laqab (honorific epithet) of Murtaḍā al-Dawla ("Approved of the State"), was the ruler of the Emirate of Aleppo between 1008 and 1016. He succeeded his father Lu'lu' al-Kabir, with whom he had shared power. Unlike Lu'lu', however, Mansur's rule was opposed by Aleppo's notables, who chafed at his oppression and monopolization of power. Both Mansur and his father harassed the remaining members of the Hamdanid dynasty, in whose name they ostensibly ruled. On the diplomatic front, Mansur balanced ties with both the Byzantine Empire and the Fatimid Caliphate, and maintained the emirate's Shia Muslim orientation.
