Umayyad conquest of Hispania
The "Reconquista", or the gradual reconquest of Muslim Iberia by the Christian kingdoms in the North, was driven by a powerful religious motivation: to reclaim Iberia for Christendom following the Umayyad conquest of Hispania centuries before. By the 14th century, most of the Iberian Peninsula (present-day Spain and Portugal) had been reconquered by the Christian kingdoms of Castile, Aragon, León, Galicia, Navarre, and Portugal.
