The son and successor of Malik-Shah I (r. 1072–1092), he reigned during the opening stages of the decline and fragmentation of the empire, which marked the rise of Turkoman atabegates and principalities, which would eventually stretch from Kirman to Anatolia and Syria. His reign was marked by internal strife, mainly against other Seljuk princes. Read more on Wikipedia
