Banu Kalb
The orientalist Henri Lammens considers Yazid's portrayal as "a pro-Mudar and anti-Yaman extremist" as "unfair, as he actually tried to balance the conflicting groups, just as other Umayyad rulers did". Yazid did not champion the Qays over the Quda'a, a major component of the Yaman confederation in Syria. Indeed, members of the Quda'a's principal tribe, the Banu Kalb, had formed the core of the caliph's army during the suppression, pursuit and elimination of the Muhallabids. He appointed Yamani governors to the large provinces of Ifriqiya (North Africa west of Egypt) and the Jazira (Upper Mesopotamia) and its dependent districts of Adharbayjan and Armenia.
