in 1131, dying a year later due to his injuries. Ridwan died in 1113 and was succeeded as ruler of Aleppo by his son Alp Arslan al-Akhras. Alp Arslan continued his father's conciliatory approach to the Assassins. A warning from Muhammad I Tapar and a prior attempt of the assassination of Abu Harb Isa ibn Zayd, a wealthy Persian merchant, led to a wholescale expulsion of the Assassins from Aleppo in that same year. Led by militia commander Sāʿid ibn Badī, the attack resulted in the execution of Abu Tahir al-Sa’igh and the brother of al-Hakim al-Munajjim, with 200 other Assassins killed or imprisoned, some thrown from the top of the citadel. Many took refuge with the Banu Munqidh at Shaizar. Revenge was slow but sure, taken out on Sāʿid ibn Badī in 1119. The shiftless Arp Arslan had exiled Sāʿid to Qalʿat Jaʿbar, where he was murdered along with two of his sons by Assassins. The Assassins struck again in Damascus in 1116. While a guest of Toghtekin's, Kurdish emir Ahmad-Il ibn Ibrāhim ibn Wahsūdān was sitting next to his host when a grieving man approached with a petition he wished be conveyed to Muhammad I Tapar. When Ahmad-Il accepted the document, he was stuck with a dagger, then again and again by a second and third accomplice. It was thought that the real target may have Toghtekin, but the attackers were discovered to be Assassins, likely after Ahmad-Il, the foster brother of sultan. In 1118, Muhammad I Tapar died and his brother Ahmad Sanjar became Seljuk sultan, and Hassan sent ambassadors to seek peace. When Sanjar rebuffed these ambassadors, Hassan then sent his Assassins to the sultan. Sanjar woke up one morning with a dagger stuck in the ground beside his bed. Alarmed, he kept the matter a secret. A messenger from Hassan arrived and stated, "Did I not wish the sultan well that the dagger which was struck in the hard ground would have been planted on your soft breast". For the next several decades there ensued a ceasefire between the Isma'ilis and the Seljuks. Sanjar himself pensioned the Assassins on taxes collected from the lands they owned, gave them grants and licenses, and even allowed them to collect tolls from travelers. By 1120, the Assassins position in Aleppo had improved to the point that they demanded the small citadel of Qal'at ash-Sharif from Ilghazi, then Artuqid
