period. When Jalal al-Din Hasan III succeeded as Isma'ili imam in 1210 (607 AH) he claimed to have converted to Sunni Islam and took the name "Naw-Musalmān" meaning "New Muslim". The people of Qazvin were skeptical and demanded proof, and he obliged by inviting some of Qazvin's leading men to Alamut Castle where he publicly burned Isma'ili texts for them to see. Also in 1210, the city was damaged by the forces of Kingdom of Georgia sent by Tamar the Great, as per the retribution for destroying Georgian-controlled Ani by the Muslim forces that left 12,000 Christians dead. The Mongols Meanwhile, a new threat was looming – the Mongols. Qazvin changed hands several times during their wars with the Khwarazmshahs, and in 1220 (617 AH) the Mongols massacred the city's inhabitants. It was under the Mongols that there was large-scale Turkic migration into the Qazvin area. Although at least some must have settled there during Seljuk times, it was during the Mongols that they started coming in larger numbers. Several prominent Turkic families established themselves in Qazvin. One of them was the Būlātmūriyān, who first came during the rule of Ögedei when their member Amir Takash was appointed shihna or military governor of Qazvin. Another was the Qarāvulān, who acquired large landed estates but had already lost their prominence by the time of Hamdallah Mustawfi. However, most of the main families at his time still traced their roots back to an Arab founder. The religion was mostly Sunni of the Shafi'i madhhab, although there were Shi'i and Hanafi Sunni minorities. Mangu Qa'an appointed Iftikhar al-Din Muhammad al-Bukhari as governor of Qazvin in 1253/4 (651 AH). Iftikhar al-Din learned Mongolian and translated the Kalila wa-Dimna into Mongolian. He and his brother Imam al-Din Yahya remained in office until 1278/9 (677 AH). Qazvin suffered during the tumultuous period preceding Ghazan Khan's rise to power in 1295. Many people left the town, to the point that Hamdallah Mustawfi wrote that Friday prayers could not be performed. He also mentioned Mongol reappropriation of waqf land in nearby Pishkildarra. At the end of Uljaytu's reign Qazvin became administered by Husam al-Din Amir Umar Shirazi and the mustawfi Hajji Fakhr al-Din Ahmad. When Abu Sa'id Bahadur Khan took over in 1316, he assigned the income from Qazvin to cover the expenses of his mother's household. After the fall of the Ilkhanate, Qazvin had an uneventful history
