マリク・シャー
The Assassins were immediately threatened by the forces of Seljuk sultan Malik-Shah I, marking the beginning of the Nizari-Seljuk wars. One of Sabbah's disciples named Dihdar Bu-Ali from Qazvin rallied local supporters to deflect the Seljuks. Their attack on Alamut Castle and surrounding areas was canceled upon the death of the sultan. The new sultan Barkiyaruq, son of Malik-Shah I, did not continue the direct attack on Alamut, concentrating on securing his position against rivals, including his half-brother Muhammad I Tapar, who eventually settled for a smaller role, becoming "malik" in Armenia and Azerbaijan.
