This chapter focuses on both the careers of the Muhallabids, the most prominent al-Azd family during the Umayyad period, and their role as sites of memory for later generations. It examines narratives by Abu Mikhnaf, al-Mada’ini, Wahb b. Jarir, al-Awtabi, and others for events including al-Muhallab’s war against the Azraqites, Yazid b. al-Muhallab’s governorships of Khurasan, and the Muhallabid revolt against the caliph Yazid II. In doing so, it teases out the different approaches to the family in Abbasid-era accounts, and so charts shifts in the significance of al-Azd identity in the late 700’s and 800’s. One key theme is that the Muhallabids’ significance depended in part on their ability to tap Oman as a source of military manpower. Finally, it examines the prominent Muhallabids of the early Abbasid era and their roles in the Abbasid revolution and others.
