In the summer of 1083, the former Marwanid vizier Fakhr al-Dawla ibn Jahir persuaded the Seljuk Sultan Malikshah to send him with an army against the Marwanid emirate, and eventually Jazirat Ibn ʿUmar, the last remaining stronghold, was captured in 1085. Although the Marwanid emirate was severely reduced, its final emir Nasir al-Dawla Mansur was permitted to continue to rule solely Jazirat Ibn ʿUmar under the Seljuk Sultanate from 1085 onwards. The mamluk Jikirmish seized Mansur and usurped the emirate of Jazirat Ibn ʿUmar on Mansur's death in January 1096. In late 1096, Jikirmish set out to relieve Kerbogha's siege of Mosul following a request for aid from the Uqaylid Emir Ali ibn Sharaf al-Dawla of Mosul, but was defeated by Kerbogha's brother Altuntash, and submitted to him as a vassal. Jikirmish was forced to aid in the ultimately successful siege against his former ally, and thus came under the suzerainty of Kerbogha as Emir of Mosul. Kerbogha died in 1102, and Sultan Barkiyaruq appointed Jikirmish as his replacement as emir. Jazirat Ibn ʿUmar was thereafter directly ruled over by a string of Seljuk emirs of Mosul until the appointment of Zengi.
