emir of Aleppo. Rather than refuse, he had the citadel demolished. The end of Assassin influence in Aleppo ended in 1124 when they were expelled by Belek Ghazi, a successor to Ilghazi. Nevertheless, the qadi ibn al-Khashahab who had overseen the demolition of Qal'at ash-Sharif was killed by Assassins in 1125. At the same time, the Assassins of Diyarbakir were set upon by the locals, resulting in hundreds killed. No one was more responsible for the succession crisis that caused the exile of Nizar ibn Mustarstir than the powerful Fatimid vizier al-Afdal Shahanshah. In 1121, al-Afdal was murdered by three Assassins from Aleppo, causing a seven-day celebration among the Isma'ilis and no great mourning among the court of Fatimid caliph al-Amir bi-Ahkam Allah who resented his growing boldness. Al-Afdal Shahanshah was replaced as vizier by al-Ma'mum al-Bata'ihi who was instructed to prepare a letter of rapprochement between Cairo and Alamut. Upon learning of a plot to kill both al-Amir and al-Ma'mum, such ideas were disbanded, and severe restrictions on dealing with the Assassins were instead put in place. The next generation In 1124, Hassan-i Sabbah died, leaving a legacy that reverberated throughout the Middle East for centuries. He was succeeded at Alamut by Kiya Buzurg Ummid. The appointment of a new da'i at Alamut may have led the Seljuks to believe the Assassins were in a weakened position, and Ahmad Sanjar launched an attack on them in 1126. Led by Sanjar's vizier Mu'in ad-Din Kashi, the Seljuks again struck at Quhistan and also Nishapur in the east, and at Rudbar to the north. In the east, the Seljuks had minor successes at a village near Sabzevar, where the population was destroyed, their leader leaping from the mosque's minaret, and at Turaythirth in Nishapur, where the attackers "killed many, took much booty, and then returned." At best, the results were not decisive, but superior to the routing the Seljuks received in the north, with one expedition driven back, losing their previous booty, and another having a Seljuk commander captured. In the end, the Isma'ili position was better than before the offensive. In the guise of a peace offering of two Arabian horses, Assassins gained the confidence of Mu'in ad-Din Kashi and killed him in 1127. At the same time, in Syria, a Persian named Bahram al-Da'i, the successor to Abu Tahir al-Sa’igh who had been executed in Aleppo in 1113, appeared
