Fall of the Caliphate of Córdoba
Muslim Spain breaks up into dozens of taifas
The civil war that began in 1009 toppled caliph after caliph, and in 1031 the notables of Córdoba abolished the caliphate. Al-Andalus split into taifas, petty emirates that were soon paying tribute to the Christian kings.
