Idrisid dynasty
The city fell to local tribes around 285 and was never retaken by Rome because of its remoteness and indefensibility on the south-western border of the Roman Empire. It continued to be inhabited for at least another 700 years, first as a Latinised Christian community, then as an early Islamic settlement. In the late 8th century it became the seat of Idris ibn Abdallah, the founder of the Idrisid dynasty of Morocco. By the 11th century Volubilis had been abandoned after the seat of power was relocated to Fes. Much of the local population was transferred to the new town of Moulay Idriss Zerhoun, about from Volubilis.
