Tāj al-Dawla Alp Arslān ibn Riḍwān,[1] nicknamed al-Akhras ('The Mute'),[2] was the Seljuk sultan of Aleppo from AD 1113 (AH 507) until his death in 1114 (508).
[3] Historian Amin Maalouf wrote that Alp Arslan, in addition to his brothers, executed "several officers, a few servants, and in general anyone to whom he took a dislike".
[6] At the suggestion of Sāʿid ibn Badīʿ, raʾīs ('leader') of the aḥdāth, Alp Arslān persecuted the Nizārī Bāṭiniyya, executing their leader, Abū Ṭāhir al-Sāʾigh, and confiscating the properties of the rest.
[7][8] In March 1114, Alp Arslān turned to Ṭughtegin of Damascus for protection against Antioch, against the Nizārīs and against his atabeg, Luʾluʾ.
[6][8] Ṭughtegin sent forces to Aleppo, but they found the official toleration of the Shia unacceptable and left before the end of the year.
