Malik-Shah died on 19 November 1092 while he was hunting. Upon his death, the Seljuk Empire fell into chaos, as rival successors and regional governors carved up their empire and waged war against each other. The individual tribes, the Danishmends, Mangujekids, Saltuqids, Tengribirmish begs, Artuqids (Ortoqids) and Akhlat-Shahs, had started vying with each other to establish their own independent states. Malik Shāh I was succeeded in Anatolia by Kilij Arslan I, who founded the Sultanate of Rum, and in Syria by his brother Tutush I. In Persia he was succeeded by his son Mahmud I, whose reign was contested by his other three brothers Barkiyaruq in Iraq, Muhammad I in Baghdad, and Ahmad Sanjar in Khorasan. The situation within the Seljuk lands was further complicated by the beginning of the First Crusade, which detached large portions of Syria and Palestine from Muslim control in 1098 and 1099. The success of the First Crusade is at least in part attributable to the political confusion which resulted from Malik-Shah's death
