Arab Muslim dynasty that ruled Berber areas of Morocco (789921).
The founder, Idr 012B; s I (r. 789791), established the sharifian tradition in Morocco, by which the claim to descent from Muhammad was established as the principle for monarchic rule. His son Idr 012B; s II (r. 803828) founded Fez (modern Fès ) in 808. The dynasty was the first to incorporate both Berbers and Arabs . It broke up into rival principalities, paving the way for another Berber group, the Almoravid dynasty .
