Page "Alp Arslan" Paragraph 16

Suleiman ibn Kutalmish was the son of the contender for Arslan's throne ; he was appointed governor of the north-western provinces and assigned to completing invasion of Anatolia.

An explanation for this choice can only be conjectured from Ibn al-Athir ’ s account of the battle between Alp-Arslan and Kutalmish, in which he writes that Alp-Arslan wept for the latter's death and greatly mourned the loss of his kinsman.
