Input: Question: How long did the Almohads rule Annaba? Passage:The Phoenicians settled in Annaba during the 14th century BC. Hippo Regius was a center of early Western Christianity, and it was the site of many Christian synods, one of which was a key site for the dissemination of the books of the New Testament. Augustine of Hippo was bishop here from 396 AD until his death in 430 AD. The city was destroyed in the 5th century by the Vandals. Vandals ruled the city for roughly a century until 534. Gelimer, the King of the Vandals and Alans from 530 to 534 AD, faced with the starvation of his followers and their children, and realizing he had no chance of regaining his kingdom of North Africa, surrendered to Flavius Belisarius, a general of the Byzantine Empire under Justinian I, at Bône. Byzantines then ruled Hippona (Hippo's renamed name after 395) before the Muslim conquest of the Maghreb in 699 AD. Later, Abbasids, Aghlabids, and Fatimids ruled Bona before the rise of the Zirids. It was relocated to its present place after flooding and Banu Hilal the ravages that occurred in 1033 during Hammadid rule. It was attacked by a Pisan and Genovese fleet in 1034 and was conquered by Kingdom of Sicily in 1153. The Almohads took it in 1160.
