The purpose of the Reconquista was to reclaim and establish Christian rule in the Iberian Peninsula, which had come under Muslim control during the early 8th century. It was a long and intermittent process that took place between the 8th and 15th centuries, involving a series of military campaigns and conflicts. The Reconquista was driven by religious, political, and territorial motivations, as well as the desire to restore Christian influence and culture to the region.
