Salih ibn Mirdas . Salih ibn Mirdas (died 1029) was the founder of the Mirdasid dynasty and emir of Aleppo from 1025 until his death. His sons and grandsons ruled Aleppo for most of the next five decades. In 1008 he seized the Euphrates river fortress of al-Rahba. He was imprisoned and tortured in 1012 by the emir of Aleppo, Mansur ibn Lu'lu', before escaping two years later and capturing Mansur in battle. With his Bedouin warriors, Salih captured a string of fortresses along the Euphrates, including Manbij and Raqqa, by 1022. He later allied with the Banu Kalb and Banu Tayy tribes in their rebellion against the Fatimids of Egypt, who ruled Aleppo. He annexed the central Syrian towns of Homs, Baalbek and Sidon before conquering Aleppo in 1025 and establishing a well-organized administration. He paid formal allegiance to the Fatimids, but his alliance with the Banu Tayy drew him into conflict with the Fatimid general, Anushtakin al-Dizbari, whose forces killed Salih in battle n
