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). According to Ibn al-Athīr, he was not actually mute but had only a speech impediment and a stammer. He was the son of the Sultan Riḍwān by a daughter of Yağısıyan, governor of Antioch.[3]
