Kilij Arslan I
In 1086, Suleiman, seeking to expand his dominion, placed Aleppo under siege and demanded its surrender. The emir of Aleppo sent a message to Tutush I, the Seljuk ruler of Syria, stating he would hand the city over to him. Suleiman, hearing of the approach of Tutush's forces, raised the siege and marched to meet him. Near Aleppo, Suleiman's forces fled before Tutush's army, while Suleiman was killed. Suleiman's son, Kilij Arslan I, was captured, and Malik Shah transferred him to Isfahan as a hostage.
