with which Nasr was regarded by the native population in Transoxiana, that in contrast to Khurasan, no native city there welcomed the Hashimi missionaries, and that they remained loyal to him even during the later Abbasid Revolution. Civil wars and the Abbasid Revolution In 743, after the death of Caliph Hisham, his successor, Walid II, reconfirmed Nasr in his post. The influential governor of Iraq, Yusuf ibn Umar al-Thaqafi, an opponent of Nasr, tried to lure him away from his province by calling him to Iraq. Nasr delayed his departure, stalling for time, and was saved by the murder of Walid in April 744. Walid's successor, Yazid III, moved to install a regime dominated by the Yemeni Kalb tribe. Nasr's position was severely undermined, and the Yemeni faction now hoped to see their leader, Juday al-Kirmani, appointed governor in his stead.

It is indicative of the lingering inter-tribal antagonism of the late Umayyad world that the rebellion was launched in the name of revenge for the Muhallabids, an Azd family that had been purged after rebelling in 720—an act which had since become a symbol of Yemeni resentment of the Umayyads and their northern Arab-dominated regime. On 13 July 744, Nasr captured and imprisoned al-Kirmani. After barely a month, the latter escaped, and his rebellion was joined not only by Azd soldiers, but also by many of the Arab settlers around Marv. A tentative truce was initially agreed upon, during which fruitless negotiations were conducted, but after Yazid reconfirmed Nasr in his post, al-Kirmani and the Yemenis—in reality, al-Kirmani's followers included other tribes as well, including most of the Syrians and even some Mudaris, but they were collectively called in the
