Nāṣir al-Dawla Abū ʿAlī al-Ḥusayn ibn al-Ḥasan (Arabic: ناصر الدولة أبو علي الحسين بن الحسن), better known by his honorific epithet as Nasir al-Dawla Ibn Hamdan,[1][2] was a descendant of the Hamdanid dynasty who became a general of the Fatimid Caliphate, ruing Egypt as a de facto dictator in 1071–1073.
He was later appointed governor of Alexandria, where he expelled the rebellious Bedouin Abu Qurra clan from the western Nile Delta.
He was released shortly after, as Mahmud tried to gain Fatimid support against his uncle, Mu'izz al-Dawla Thimal, who was seeking to recover control of Aleppo.
[10] Nasir al-Dawla played a leading role in the civil war of 1067 to 1073 between the Fatimids' Turkish and Nubian troops as the leader of the former.
[contradictory] The anarchic conditions in the country continued until al-Mustansir called upon the governor of Palestine, Badr al-Jamali, for aid in late 1073.
