From 1092, the status quo in the Middle East disintegrated following the death of the effective ruler of the Seljuk Empire, Nizam al-Mulk. This was closely followed by the deaths of the Seljuk sultan Malik-Shah and the Fatimid caliph al-Mustansir Billah. Wracked by confusion and division, the Islamic world disregarded the world beyond, so that, when the First Crusade arrived, it came as a surprise. Malik-Shah was succeeded in the Anatolian Sultanate of Rûm by Kilij Arslan, and in Syria by his brother Tutush I who started a civil war against Berkyaruq to become sultan himself. When Tutush was killed in 1095, his sons Ridwan and Duqaq inherited Aleppo and Damascus, respectively, further dividing Syria amongst emirs antagonistic towards each other, as well as Kerbogha, the atabeg of Mosul. Egypt and much of Palestine were controlled by the Fatimids. The Fatimids, under the nominal rule of caliph al-Musta'li but actually controlled by vizier al-Afdal Shahanshah, lost Jerusalem to the Seljuks in 1073 but succeeded in recapturing the city in 1098 from the Artuqids, a smaller Turkish tribe associated with the Seljuks, just before the arrival of the crusaders.
