The Hammudids, said to be a collateral branch of the Idrisides, were the
only Taifa rulers to put a direct dynastic claim on the Umayyad Caliphate of
Al-Andalus and used for themselves the title Imam on all their coins. A
dynastic claim directly based on a false letter purportedly sent by Hisham
II to the then governor of Ceuta , ´Ali ibn Hammud, appointing him as his
successor.
