Muslim Iberia

The Alhambra palace complex in Granada.In the 8th century, nearly all of the Iberian Peninsula was conquered by Muslim armies (see Moors) from North Africa. These conquests were part of the expansion of the Umayyad Islamic Empire.Only a number of areas in the mountainous north of the Iberian Peninsula managed to resist the initial invasion and they were the starters of the Reconquista. These areas roughly corresponding to modern Asturias, Cantabria, Navarre and northern Aragon.
Under Islam, Christians and Jews were recognised as "peoples of the book", and were free to practice their religion, but faced a number of mandatory discriminations and penalties as dhimmis. Conversion to Islam proceeded at a steadily increasing pace. The muladies are believed to have comprised the majority of the population of Al-Andalus by the end of the 10th century. La Giralda, the bell tower of the Seville Cathedral.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 in the mountainous region of Granada.
Córdoba, the capital of the caliphate, was the largest, richest and most sophisticated city of medieval western Europe.[note 11] Mediterranean trade and cultural exchange flourished. Muslims imported a rich intellectual tradition from the Middle East and North Africa. Muslim and Jewish scholars played an important part in reviving and expanding classical Greek learning in Western Europe. The Romanized cultures of the Iberian peninsula interacted with Muslim and Jewish cultures in complex ways, thus 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 a remarkable expansion of agriculture.
However, by the 11th century, Muslim holdings had fractured into rival Taifa kingdoms, allowing the small Christian states the opportunity to greatly enlarge their territories and consolidate their positions.The arrival of the North African Muslim ruling sects of the Almoravids and the Almohads restored unity upon Muslim holdings, with a stricter, less tolerant application of Islam, but ultimately, after some successes in invading the north, proved unable to resist the increasing military strength of the Christian states.
