The Conquest (711-722 CE)
In 711 CE, after the Visigothic Kingdom of Iberia had weakened through internal conflict, the Umayyad general Musa ibn Nusayr sent Tariq ibn Ziyad with an army across the strait now bearing his name. The decisive Battle of Guadalete (July 711) destroyed the Visigothic forces under King Roderic. Within three years, Islamic armies had reached as far north as the Pyrenees.
The conquest was rapid partly because many of the Iberian population — particularly Jews who had suffered under the Visigoths — welcomed the Muslim armies or at least offered no resistance. The Umayyad policy of dhimmi status for Christians and Jews (religious and legal autonomy in exchange for the jizya tax) was more tolerant than the Visigothic Christian supremacism.
The bridge at Tours/Poitiers (732 CE): Charles Martel’s victory over the advancing Islamic forces at Tours/Poitiers is often cited in Western history as the turning point that “saved Europe.” Modern historians note that the Islamic forces were likely a raiding party rather than a full conquest army, and that internal divisions and supply challenges had already limited their northward advance.
The Umayyad Emirate and Caliphate of Cordoba (756-1031 CE)
‘Abd al-Rahman I (r. 756-788 CE) — an Umayyad prince who escaped the Abbasid massacre of his dynasty — established an independent emirate in Cordoba. His arrival transformed al-Andalus from an Abbasid province to an independent power.
‘Abd al-Rahman III (r. 912-961 CE) declared himself Caliph in 929 CE — challenging both the Abbasids in Baghdad and the Fatimids in North Africa. Under his rule and that of his successor al-Hakam II, Cordoba became:
- A city of 500 mosques, 300 public baths, and 70 libraries at a time when the rest of Europe had almost none
- Home to a population estimated at half a million — the largest in Western Europe
- The intellectual center of the Western world, with scholars coming from throughout Europe to study
The Great Mosque of Cordoba (La Mezquita) — begun by ‘Abd al-Rahman I in 785 CE and expanded multiple times — remains one of the most extraordinary architectural achievements in Islamic history.
The Convivencia — Coexistence in Al-Andalus
The period of convivencia (Latin: coexistence) in al-Andalus — particularly from the 9th through 11th centuries — represents a historical case study in multi-religious intellectual cooperation:
- Jewish scholars wrote philosophy and poetry in Arabic
- Christian scholars came to Andalusian cities to access the preserved texts of classical antiquity
- Scholars of all three Abrahamic faiths participated in the translation movement that transmitted Greek philosophy and science to medieval Europe
- Figures like Maimonides, who wrote in Arabic as naturally as Hebrew, and Ibn Rushd, whose commentaries were foundational to European scholasticism, emerged from this environment
The convivencia was not perfectly harmonious — there were periods of discrimination and violence — but it was a qualitatively different model from the religious persecution that characterized much of the rest of medieval Europe.
The Reconquista (718-1492 CE) and the End of Al-Andalus
The Christian kingdoms of northern Iberia never fully disappeared and gradually pushed southward in a process called the Reconquista (reconquest). Key moments:
- 1085 CE: Toledo falls to Alfonso VI of Castile
- 1212 CE: Battle of Las Navas de Tolosa — decisive defeat of the Almohad forces
- 1492 CE: Fall of Granada — the last Islamic kingdom in Iberia, ruled by Muhammad XII (Boabdil)
In 1492 — the same year Columbus reached the Americas — the Alhambra Decree expelled all Jews from Spain. The Muslims were subsequently forced to choose between conversion and exile; many converted nominally (Moriscos) while secretly maintaining their faith until mass expulsion in 1609-1614 CE.
The Legacy
Al-Andalus gave medieval Europe: algebra (from al-Khwarizmi via Toledo translations), astronomical instruments, the three-course meal structure, the acoustic guitar (predecessor to the oud), and the philosophical commentaries that sparked the European Renaissance and Scholasticism.
The poet-king al-Mu’tamid of Seville, deposed and exiled to Morocco in 1091 CE, wrote on the experience of loss that defines al-Andalus’s emotional legacy: “I said to the sea: ‘Do you know who I am? I who left my palaces for you?’ The sea was silent.”
