=== Muslim infighting ===
Similarly, there was frequent Muslim infighting throughout the existence of al-Andalus. The [[Abbasid Revolution]] (747–750) divided Muslim rulers in Iberia into the pro-[[Abbasid Caliphate]] faction (based in [[Baghdad]]) and the pro-[[Umayyad Caliphate|Umayyad faction]] (reconstituted as the [[Emirate of Córdoba]]).<ref>{{cite book |last=Ullidtz |first=Per |date=2014 |title=1016: The Danish Conquest of England |location=Copenhagen |publisher=Books on Demand |isbn=978-87-7145-720-9 |url={{GBurl|kXGaAwAAQBAJ|page=132}} |page=132}}</ref> [[Charlemagne]]'s failed [[Abbasid-Carolingian Alliance#Military alliance in Spain (777–778)|778 campaign into Iberia]] was prompted by the invitation of the pro-Abbasid governor of Barcelona, [[Sulayman al-Arabi]], which led to a brief [[Abbasid-Carolingian Alliance]] against the Umayyads.{{sfn|Ullidtz|2014|p=132}} During the [[Fitna of al-Andalus]] (1009–1031), the Umayyad-run [[Caliphate of Córdoba]] fell apart into rival [[taifa]]s headed by Islamic emirs warring each other.<ref>{{cite book|title=Europe and the Islamic World: A History|year=2013|publisher=Princeton University press|last=Tolan|first=John|place=Princeton|pages= 39–40}}</ref> After the Christian king of Castile and León [[History of Toledo, Spain#Medieval Toledo after the Reconquest|conquered Toledo]] in 1085, the emirs requested [[Yusuf ibn Tashfin]], leader of the strict Islamic [[Almoravid dynasty|Almoravid]] sect, to come to their defence, which he did at the [[Battle of Sagrajas]] (1086). However, Yusuf soon turned on the Muslim emirs of Spain, defeating them all and conquering their lands by 1091.<ref>''Encarta Winkler Prins Encyclopaedia'' (1993–2002) s.v. "Almoraviden §2.

This succession conflict took place simultaneously with the [[Granada War]], and was ended only by the Castilian conquest in 1492.<ref>''Encarta Winkler Prins Encyclopaedia'' (1993–2002) s.v.
