who invaded the iberian peninsula and lived there for eight centuries
Iberian Peninsula From the 8th–15th centuries, only the southern part of the Iberian Peninsula was part of the Islamic world. It became a center of culture and learning, especially during the Caliphate of Córdoba, which reached its height of its power under the rule of Abd-ar-Rahman III and his successor al-Hakam II.[31] The Muslims, who were initially Arabs and Berbers, included some local converts, the so-called Muladi.[32] The Muslims were referred to by the generic name, Moors[33] The Reconquista gained momentum on c. 718, when the Christian Asturians opposed the Moors. The southern march to push out the Muslims continued for three hundred years[citation needed]. For another four hundred years, only the southern part of the Iberian Peninsula was transformed into a Romance-speaking and Arabic-speaking Muslim land, along with pockets of a large minority of Arabic-speaking Sephardi Jews[citation needed].
Portuguese colonization of the Americas Portugal was the leading country in the European exploration of the world in the 15th century. The Treaty of Tordesillas in 1494 divided the Earth outside Europe into Castilian and Portuguese global territorial hemispheres for exclusive conquest and colonization. Portugal colonized parts of South America (mostly Brazil), but also made some unsuccessful attempts to colonize North America in present-day Canada.
