 Malik-Shah was succeeded in the Anatolian Sultanate of Rûm by Kilij Arslan I, and in Syria by his brother Tutush I, who died in 1095.Tutush's sons Fakhr al-Mulk Radwan and Duqaq inherited Aleppo and Damascus respectively, further dividing Syria amongst emirs antagonistic towards each other, as well as Kerbogha, the atabeg of Mosul.This disunity among the Anatolian and Syrian emirs allowed the crusaders to overcome any military opposition they faced on the way to Jerusalem.
