Nasr ibn Mahmud
Nasr ibn Mahmud ibn Nasr ibn Salih ibn Mirdas was the Mirdasid emir of Aleppo in 1075–1076.
Family
Nasr was the eldest son of Mahmud ibn Nasr, the Mirdasid emir of Aleppo. Nasr's mother was a daughter of the Buyid emir al-Malik al-Aziz ibn Jalal al-Dawla. His brothers, from a different mother, were Sabiq, Waththab and Shabib and sister Mani'a.Rule
Mahmud designated his youngest son Shabib as his successor, but upon Mahmud's death in early 1075, Nasr was recognized as Aleppo's emir. Shabib was still young and the leading officials of the emirate, as well as its troops, favored Nasr. As soon as he took office he executed his father's vizier, the commander Ali ibn Abi al-Thurayya, having accused him of influencing Mahmud's nomination of Shabib. In his place, Nasr appointed Abu Nasr Muhammad ibn al-Hasan al-Tamimi, known as Ibn al-Nahhas. Nasr entrusted his foster-uncle, the Banu Munqidh emir Sadid al-Mulk Ali ibn Muqallid, to oversee most of his leadership duties. Sadid al-Mulk and Ibn al-Nahhas shared an interest in literature and developed a strong working relationship. According to the historian Thierry Bianquis, Nasr "showed himself to be more peaceful and more generous than his father".He enjoyed the support of the Turkmen forces based in Aleppo, who were commanded by a certain Ahmad Shah. The latter besieged and captured Manbij from the Byzantines in September/October 1075. Not long after, Aleppo's southern countryside was raided by the Seljuk ruler of Damascus, Atsiz, and his brother Jawli. During the assault, they captured Rafaniyya. After Nasr's attempt to pay Atsiz to withdraw was rebuffed, he dispatched Ahmad Shah against him. Ahmad Shah fought the Seljuks in two engagements and drove them out, restoring Mirdasid control over Rafaniyya.
