Isidore created the first western encyclopedia which had a huge impact during the Middle Ages.
Muslim Era and Reconquista:
In the 8th century, nearly all of the Iberian Peninsula was conquered (711–718) by largely Moorish Muslim armies from North Africa. These conquests were part of the expansion of the Umayyad Caliphate. Only a small area in the mountainous north-west of the peninsula managed to resist the initial invasion. Legend has it that Count Julian, the governor of Ceuta, in revenge for the violation of his daughter, Florinda, by King Roderic, invited the Muslims and opened to them the gates of the peninsula.
Under Islamic law, Christians and Jews were given the subordinate status of dhimmi. This status permitted Christians and Jews to practice their religions as People of the Book but they were required to pay a special tax and had legal and social rights inferior to those of Muslims.
Conversion to Islam proceeded at an increasing pace. The muladíes (Muslims of ethnic Iberian origin) are believed to have formed the majority of the population of Al-Andalus by the end of the 10th century.
The Muslim community in the Iberian Peninsula was itself diverse and beset by social tensions. The Berber people of North Africa, who had provided the bulk of the invading armies, clashed with the Arab leadership from the Middle East. Over time, large Moorish populations became established, especially in the Guadalquivir River valley, the coastal plain of Valencia, the Ebro River valley and (towards the end of this period) in the mountainous region of Granada.
Córdoba, the capital of the caliphate since Abd-ar-Rahman III, was the largest, richest and most sophisticated city in western Europe. Mediterranean trade and cultural exchange flourished. Muslims imported a rich intellectual tradition from the Middle East and North Africa. The Romanized cultures of the Iberian Peninsula interacted with Muslim and Jewish cultures in complex ways, giving the region a distinctive culture. Outside the cities, where the vast majority lived, the land ownership system from Roman times remained largely intact as Muslim leaders rarely dispossessed landowners and the introduction of new crops and techniques led to an expansion of agriculture introducing new produces which originally came from Asia or the former territories of the Roman Empire.
In the 11th century, the Muslim holdings fractured into rival Taifa states (Arab, Berber, and Slav), allowing the small Christian states the opportunity to greatly enlarge their territories. The arrival from North Africa of the Islamic ruling sects of the Almoravids and the Almohads restored unity upon the Muslim holdings, with a stricter, less tolerant application of Islam, and saw a revival in Muslim fortunes. This re-united Islamic state experienced more than a century of successes that partially reversed Christian gains.
The Reconquista (Reconquest) was the centuries-long period in which Christian rule was re-established over the Iberian Peninsula. The Reconquista is viewed as beginning with the Battle of Covadonga won by Don Pelayo in 722 and was concurrent with the period of Muslim rule on the Iberian Peninsula. The Christian army’s victory over Muslim forces led to the creation of the Christian Kingdom of Asturias along the northwestern coastal mountains. Shortly after, in 739, Muslim forces were driven from Galicia, which was to eventually host one of medieval Europe’s holiest sites, Santiago de Compostela and was incorporated into the new Christian kingdom.
