The Arabs managed to bring Balkh under their control only in 715 AD, in spite of strong resistance offered by the Balkh people during the Umayyad period. Qutayba ibn Muslim al-Bahili, an Arab General was Governor of Khurasan and the east from 705 to 715. He established a firm hold over lands beyond the Oxus for the Arabs. He fought and killed Tarkhan Nizak in Tokharistan (Bactria) in 715. In the wake of Arab conquest, the resident monks of the Vihara were either killed or forced to abandon their faith. The Viharas were razed to the ground. Priceless treasures in the form of manuscripts in the libraries of monasteries were consigned to ashes. Presently, only the ancient wall of the town, which once encircled it, stands partially. Nava-Vihara stands in ruins, near Takhta-i-Rustam. In 726, the Umayyad governor Asad ibn Abdallah al-Qasri rebuilt Balkh and installed in it an Arab garrison, while in his second governorship, a decade later, he transferred the provincial capital there.
