The Iberian Peninsula was largely divided before the hallmark of this marriage. Five independent kingdoms: Portugal in the West, Aragon and Navarre in the East, Castile in the large center, and Granada in the south, all had independent sovereignty and conflicting interests. The conflict between Christians and Muslims to control Iberia, which started from North African Muslim's successful launch of attack in 711, lasted from the years 718 to 1492. Christians, fighting for control, successfully pushed the Muslims back to Granada, which was the Muslim's last control of the Iberia.
