 Under Ali, the Banu Munqidh played a dominant role in the affairs of their nominal Mirdasid suzerains.Tensions with the Mirdasid emir of Aleppo, Mahmud ibn Nasr, led Ali to depart Aleppo for Tripoli where he was able to gain further recognition of the Banu Munqidh's budding principality in the middle Orontes valley.During the chaotic succession process following Mahmud's death, Ali was instrumental in installing Mahmud's son Sabiq as Aleppo's emir.
