Banu Tujibi

The Banu Tujibi were an Arab dynasty that were appointed to govern Calatayud in 872, and in 886 were given Zaragoza. This they held as governors (sometimes only nominally, carrying out their own foreign policy) under the Umayyads. The collapse of the Caliphate of Córdoba allowed them to found the Taifa of Zaragoza, which they ruled from 1018 until they were expelled by a rival dynasty, the Banu Hud, in 1039.
