It wasn't until later centuries that the Christians started to see their conquests as part of a secular effort to restore the unity of the Visigothic kingdom.
The battle against Moors didn't keep the Christian kingdoms of battling among themselves or allying with Islamic kings. For example, the earlier kings of Navarre were family of the Banu Qasi[?] of Tudela[?]. The Moorish kings often have wives or mothers born Christians. Also Christian champions like the Cid were contracted byt Taifa[?] kings to fight against their neighbours.
In the late years of Al-Andalus[?], Castile had the military power to conquest the remains of the kingdom of Granada, but the kings preferred to claim the tribute of the parias[?]. The commerce of Granadan goods and the parias were a main way for the African gold to enter medioeval Europe[?].
In the High Middle Ages[?], the fight against the Moors in Iberia was linked to the fight of the whole Christendom. Military orders like order of Santiago[?], Montesa[?], the Temple Knights were founded or called. The Popes called the knights of Europe to the Crusades in the Peninsula. French, Navarrese, Castilian and Aragonese armies united in the massive battle of Las Navas de Tolosa (1212).

Currently, along the Mediterranean coast, the festivals of moros y cristianos[?] ("Moors and Christians") recreate the fights as colourful parades with elaborate garments and lots of fireworks.
