The betrayal of a rogue Byzantine officer gave Muslims, specifically the North African Aghlabid dynasty, an opportunity for the conquest of Sicily. The Muslims embarked on what was to be a 130-year conquest of the island. Like Spain, Sicily became an exemplary Euro-Islamic state marked by an appreciation for erudition of all peoples and the diversity within its own population. Muslim power passed from the Aghlabids to the Fatimids who gave control of the island to the Kalbites. In much the same way as the island came into the hands of the Muslims, it was so taken away. A disgruntled governor appealed to the Normans (Vikings) in Italy for aid against his own coreligionists.
