…Ismailis under the leadership of Hassan-e Sabbah seize the fortress of Alamut.

Moreover, the succession to the sultanate has been complicated by the death of two of Malik Shah's eldest sons: Dawud (died 1082) and Ahmad (died 1088), whom both were sons of the Kara-Khanid Princess Turkan Khatun, she also has a named Mahmud (born 1087) who she wants to succeed his father, while Nizam and most of the Seljuq army is in favor of Barkiyaruq, the oldest of Malik Shah's living sons and one born to a Seljuq princess.

Turkan Khatun now allies with Taj al-Mulk Abu'l Ghana'im to try to remove Nizam from his post.

Taj even accuses Nizam of corruption before the sultan.

Malik Shah I, however, does not dare to dismiss Nizam.

Nizam later besieges Alamut, but is forced to withdraw.
