[1] Abd al-Wahid was back in Marrakesh in February 1224, when his grand-nephew, the young Almohad caliph Yusuf II, was accidentally killed, leaving no heirs.
However, the hastiness of the election and the probable unconstitutionality of these proceedings, was disputed by his other nephews, the brothers of al-Nasir, who governed in al-Andalus.
Like other leading Almohad family nobles, the brothers had probably hoped for a less-experienced and more pliable candidate, likelier to give them freer rein to carry on autonomously in the provinces, as they had enjoyed during the caliphate of Yusuf II.
[1] The succession stunt unbalanced the careful coalition that had been built up over decades, setting different branches of the Almohad family member against each other, and against the palace bureaucrats and the tribal sheikhs.
Instigated by the shadowy figure of Abu Zayd ibn Yujjan, a former high bureaucrat who had been disgraced and exiled by ibn Jami'i, the brothers decided to elect their own Caliph Abdallah al-Adil in Seville, and set about ferrying troops from Spain to challenge Abd al-Wahid I in Morocco.
