Al-Andalus
On the 30th of April 711, an army of 7,000 men led by Tariq ibn-Ziyad landed at Gibraltar. This force crossed into the Iberian Peninsula to intervene in a Visigothic civil war. The decisive Battle of Guadalete occurred on the 19th of July 711, where Tariq defeated King Roderic. Musa ibn Nusayr, governor of Ifriqiya, accompanied Tariq and brought most of the Visigothic Kingdom under Muslim rule within seven years. They expanded north across the Pyrenees to occupy Septimania in southern France. The region became a province subordinate to Ifriqiya, with governors appointed by the emir of Kairouan rather than Damascus. Córdoba served as the regional capital while Muslim settlers distributed widely across the peninsula. Berber soldiers garrisoned the center and north, including the Pyrenees, while colonists settled throughout all regions. Resistant Visigoths fled to the Cantabrian highlands to form the Kingdom of Asturias. In the 720s, raids into Aquitaine were halted by Duke Odo the Great at the Battle of Toulouse in 721. Charles Martel later defeated the Andalusi raiding army at Poitiers in 732, killing Al Ghafiqi. By 759, the Franks captured Narbonne, sealing al-Andalus off from further expansion into Francia.
Abd al-Rahman I arrived on the coast of Spain in 755 after fleeing the Abbasids. He spent four years assessing the political situation before landing at Almuñécar. His forces conquered Málaga and Seville, then besieged Córdoba. Despite starvation and a truce offer involving marriage to his enemy's daughter, he persisted until defeating Yūsuf al-Fihri. He proclaimed himself emir in 756 and controlled all of al-Andalus. Abd al-Rahman III declared himself caliph in 929, marking the start of the Caliphate period. Córdoba became one of the largest cities in the world with over half a million inhabitants. It surpassed Constantinople as the most prosperous city globally during this era. The city hosted extensive trade in silk, ceramics, gold, grain, olive oil, and wine. Amalfitan merchants traded Fatimid and Byzantine silks there by the tenth century. Abd al-Hakam II built libraries and a university that attracted scholars from across the Mediterranean. Abulcasis and Averroes produced works that influenced medieval European intellectual life. Gerard of Cremona and Michael Scot later translated these texts into Latin for Italy.
A ruinous civil war between 1009 and 1013 caused the Caliphate of Córdoba to collapse. In 1013, invading Berbers sacked Córdoba, massacring its inhabitants and burning the palace complex. The territory fragmented into independent mini-states known as taifas. Major entities included Badajoz, Toledo, Zaragoza, and Granada. These states were too weak to defend against repeated raids from Christian kingdoms like Navarre, León, Portugal, Castile, and Aragon. Alfonso VI of Castile annexed Toledo in 1085, galvanizing taifa leaders to seek outside help. Yusuf Ibn Tashfin led Almoravid campaigns into al-Andalus initially to defend the taifas. At the Battle of Sagrajas or Zallaqa, his army soundly defeated Alfonso VI. By 1090, however, he returned to conquer al-Andalus directly instead of defending it. Most taifas were annexed by 1094 except for Zaragoza which fell in 1110. Valencia was occupied in 1102 after El Cid's death. The Almohads overthrew the Almoravids in North Africa by 1147 under Abd al-Mu'min. They intervened in al-Andalus from 1146 onward taking control of the region. Ya'qub al-Mansur won a major victory at the Battle of Alarcos in 1195 against Alfonso VIII. A coalition of Christian kings defeated the Almohads at Las Navas de Tolosa in 1212. In 1228, caliph al-Ma'mun withdrew from al-Andalus leaving a political vacuum filled by new taifa kingdoms.
Scholars in al-Andalus made significant advances in medicine, astronomy, mathematics, and agronomy. Abu al-Qasim al-Zahrawi wrote Kitab al-tasrif around 1000 CE, a comprehensive medical encyclopedia used for centuries. It included illustrations of surgical instruments and sections on cauterization, incisions, venesection, wounds, and bone-setting. Ibn al-Baytar described over 1400 plants in his Comprehensive Book on Simple Drugs and Foodstuffs. The ibn Zuhr family produced five generations of medical experts focusing on dietary sciences and medicaments. Abu Marwan ibn Zuhr provided one of the earliest clinical descriptions of the scabies mite in Kitab al-Taysir. Astronomers like Maslama al-Majriti improved Ptolemy's Planisphaerium and Almagest. Abu Ishaq Ibrahim al-Zarqali calculated the motion of the solar apogee to be 12.04 seconds per year. Agronomists developed large-scale irrigation projects using water for city baths, mosques, gardens, and palaces. Ibn al-'Awwam wrote the Book of Agriculture containing 34 chapters discussing over 580 plant types. These innovations facilitated the Arab Agricultural Revolution making southern Iberia the most advanced agricultural region in Europe.
Eleven thousand eight hundred thirty-one known scholars were active between the eighth and fifteenth centuries producing thirteen thousand seven hundred thirty works. Poetry served as the prime literary genre adopting traditional forms like qaşida and maqama. The muwaşšaħ rhyme revolution emerged in the tenth and eleventh centuries featuring complex schemes with five branches interspersed with common threads ending in a kharja often in a different language. Andalusi zajal represented strophic poetry in vernacular Arabic associated with Ibn Quzman. This strophic form influenced Old Occitan lyric poetry of troubadours across Western Europe. Rithā' al-Andalus poems lamented the fall of cities drawing inspiration from historical events. Jewish poetry developed using Hebrew but adopted Arabic prosodic models and poetic genres. Ziryab arrived in Córdoba in 822 playing a role in music and cultural aspects including the nawba and zajal. Multilingual households existed with speakers of Romance dialects, Classical Arabic, Hebrew, and Berber languages. By 1260 most Christians had migrated north leaving Muslim territories reduced to Granada where over ninety percent converted to Islam. Literacy rates far exceeded those in many other western nations during this period.
Abd ar-Rahman I constructed the Great Mosque of Córdoba beginning in 785 which expanded multiple times until the tenth century. Its features included a hypostyle hall with marble columns supporting two-tiered horseshoe arches and ribbed domes. Madinat al-Zahra served as a luxurious palace-city built by Abd ar-Rahman III at the height of his power. The Pyxis of al-Mughira exemplified ivory boxes carved with vegetal figurative and epigraphic motifs produced in official workshops. The Aljaferia Palace of Zaragoza represented the most significant preserved palace from the Taifas period featuring ornamental arcades and stucco decoration. Almohad rulers built the Great Mosque of Seville incorporating a massive minaret now known as the Giralda. The Alhambra complex began under Ibn al-Ahmar integrating buildings and gardens with natural site qualities. Courtyards featured water pools or fountains while decoration focused on tile mosaics and carved stucco using geometric patterns and calligraphy. Muqarnas sculpting created three-dimensional vaulted ceilings particularly during Muhammad V's reign. Mudéjar style emerged after conquests when Christian patrons employed Muslim craftsmen to build churches and synagogues like Santa Maria la Blanca in Toledo.
The final war to conquer Granada began in earnest in 1482 capturing new cities year by year. Muhammad XII formally surrendered Granada to Catholic Monarchs on the 2nd of January 1492. By this time Muslims in Castile numbered half a million people. One hundred thousand died or were enslaved while two hundred thousand emigrated leaving two hundred thousand as residual population. Many elite Muslims including Muhammad XII found life intolerable under Christian rule passing over into North Africa. Mass forced conversions occurred in 1499 leading to revolts spreading through Alpujarras and Ronda mountains. The Capitulations of 1492 were revoked allowing open practice of Islam until 1526 in Aragon and Valencia kingdoms. In 1502 the Catholic Monarchs decreed forced conversion for all Muslims living under Crown of Castile rule. Descendants faced expulsions from Spain between 1609 and 1614 known as Moriscos. The last mass prosecution against crypto-Islamic practices happened in Granada in 1727 with most convicts receiving light sentences. The Morisco community kept their identity alive at least through the late eighteenth century.
