Arab Muslim dynasty that ruled Berber areas of Morocco (789–921).
The founder, Idrīs I (r. 789–791), established the sharifian tradition in Morocco, by which the claim to descent from Muhammad was established as the principle for monarchic rule. His son Idrīs II (r. 803–828) founded Fez (modern Fès ) in 808. The dynasty was the first to incorporate both Berbers and Almoravid dynasty .
