Al Andaluz

Al-Andalus translit. ; an, al-Andalus; ast, al-Ándalus; eu, al-Andalus; ber, ⴰⵏⴷⴰⵍⵓⵙ, label= Berber, translit=Andalus; ca, al-Àndalus; gl, al-Andalus; oc, Al Andalús; pt, al-Ândalus; es, al-Ándalus () was the Muslim-ruled area of the Iberian Peninsula. The term is used by modern historians for the former Islamic states in modern Spain and Portugal. At its greatest geographical extent, it occupied most of the peninsula and a part of present-day southern France, Septimania (8th century). For nearly a hundred years, from the 9th century to the 10th, al-Andalus extended its presence from Fraxinetum into the Alps with a series of organized raids and chronic banditry. The name describes the different Arab and Muslim states that controlled these territories at various times between 711 and 1492. These boundaries changed constantly as the Christian Reconquista progressed,"Para los autores árabes medievales, el término Al-Andalus designa la totalidad de las zonas conquistadas – siquiera temporalmente – por tropas arabo-musulmanas en territorios actualmente pertenecientes a Portugal, España y Francia" ("For medieval Arab authors, Al-Andalus designated all the conquered areas – even temporarily – by Arab-Muslim troops in territories now belonging to Spain, Portugal and France"), José Ángel García de Cortázar, ''V Semana de Estudios Medievales: Nájera, 1 al 5 de agosto de 1994'', Gobierno de La Rioja, Instituto de Estudios Riojanos, 1995, p. 52. eventually shrinking to the south and finally to the Emirate of Granada.

Following the Umayyad conquest of the Christian Visigothic kingdom of Hispania, al-Andalus, then at its greatest extent, was divided into five administrative units, corresponding roughly to modern Andalusia; Castile and León; Navarre, Aragon, Catalonia; Portugal and Galicia; and the Languedoc-Roussillon area of Occitanie. As a political domain, it successively constituted a province of the Umayyad Caliphate, initiated by the Caliph al-Walid I (711–750); the Emirate of Córdoba (c. 750–929); the Caliphate of Córdoba (929–1031); the Caliphate of Córdoba's ''taifa'' (successor) kingdoms (1009–1110); the Sanhaja Amazigh Almoravid Empire (1085–1145); the second taifa period (1140–1203); the Masmuda Amazigh Almohad Caliphate (1147–1238); the third taifa period (1232–1287); and ultimately the Nasrid Emirate of Granada (1238–1492).

Under the Caliphate of Córdoba, al-Andalus was a centre of learning, and the city of Córdoba, the second largest in Europe, became one of the leading cultural and economic centres throughout the Mediterranean Basin, Europe, and the Islamic world. Achievements that advanced Islamic and Western science came from al-Andalus, including major advances in trigonometry ( Geber), astronomy ( Arzachel), surgery ( Abulcasis Al Zahrawi), pharmacology ( Avenzoar), and agronomy (Ibn Bassal and Abū l-Khayr al-Ishbīlī). Al-Andalus became a major educational center for Europe and the lands around the Mediterranean Sea as well as a conduit for cultural and scientific exchange between the Islamic and Christian worlds.

Christians and Jews were subject to a special tax called jizya, to the state, which in return, provided internal autonomy in practicing their religion, and offered the same level of protections by the Muslim rulers. The jizya was not only a tax, however, but also a symbolic expression of subordination, according to orientalist Bernard Lewis.

For much of its history, al-Andalus existed in conflict with Christian kingdoms to the north. After the fall of the Umayyad caliphate, al-Andalus was fragmented into minor states and principalities. Attacks from the Christians intensified, led by the Castilians under Alfonso VI. The Almoravid empire intervened and repelled the Christian attacks on the region, deposing the weak Andalusi Muslim princes, and included al-Andalus under direct Berber rule. In the next century and a half, al-Andalus became a province of the Berber Muslim empires of the Almoravids and Almohads, both based in Marrakesh.

Ultimately, the Christian kingdoms in the north of the Iberian Peninsula overpowered the Muslim states to the south. In 1085, Alfonso VI captured Toledo, starting a gradual decline of Muslim power. With the fall of Córdoba in 1236, most of the south quickly fell under Christian rule, and the Emirate of Granada became a tributary state of the Kingdom of Castile two years later. In 1249, the Portuguese Reconquista culminated with the conquest of the Algarve by Afonso III, leaving Granada as the last Muslim state on the Iberian Peninsula. Finally, on January 2, 1492, Emir Muhammad XII surrendered the Emirate of Granada to Queen Isabella I of Castile, completing the Christian Reconquista of the peninsula.

Name

The toponym ''al-Andalus'' is first attested by inscriptions on coins minted in 716 by the new Muslim government of Iberia. These coins, called ''dinars'', were inscribed in both Latin and Arabic. The etymology of the name "''al-Andalus''" has traditionally been derived from the name of the ''Vandals'' (''vándalos'' in Spanish); however, proposals since the 1980s have challenged this tradition. In 1986, Joaquín Vallvé proposed that "''al-Andalus''" was a corruption of the name ''Atlantis''. Heinz Halm in 1989 derived the name from a Gothic term, ''*landahlauts'', and in 2002, Georg Bossong suggested its derivation from a pre-Roman substrate.

History

Province of the Umayyad Caliphate

During the caliphate of the Umayyad Caliph Al-Walid I, the Moorish commander Tariq ibn-Ziyad led an army of 7,000 that landed at Gibraltar on April 30, 711, ostensibly to intervene in a Visigothic civil war. After a decisive victory over King Roderic at the Battle of Guadalete on July 19, 711, Tariq ibn-Ziyad, joined by Arab governor Musa ibn Nusayr of Ifriqiya, brought most of the Visigothic Kingdom under Muslim rule in a seven-year campaign. They crossed the Pyrenees and occupied Visigothic Septimania in southern France.

Most of the Iberian peninsula became part of the expanding Umayyad Empire, under the name of ''al-Andalus''. It was organized as a province subordinate to Ifriqiya, so, for the first few decades, the governors of al-Andalus were appointed by the emir of Kairouan, rather than the Caliph in Damascus. The regional capital was set at Córdoba, and the first influx of Muslim settlers was widely distributed.

The small army Tariq led in the initial conquest consisted mostly of Berbers, while Musa's largely Arab force of over 12,000 soldiers was accompanied by a group of ''mawālī'' (Arabic, موالي), that is, non-Arab Muslims, who were clients of the Arabs. The Berber soldiers accompanying Tariq were garrisoned in the centre and the north of the peninsula, as well as in the Pyrenees, while the Berber colonists who followed settled in all parts of the country north, east, south and west. Visigothic lords who agreed to recognize Muslim suzerainty were allowed to retain their fiefs (notably, in Murcia, Galicia, and the Ebro valley). Resistant Visigoths took refuge in the Cantabrian highlands, where they carved out a rump state, the Kingdom of Asturias.

In the 720s, the al-Andalus governors launched several ''sa'ifa'' raids into Aquitaine but were severely defeated by Duke Odo the Great of Aquitaine at the Battle of Toulouse (721). However, after crushing Odo's Berber ally Uthman ibn Naissa on the eastern Pyrenees, Abdul Rahman Al Ghafiqi led an expedition north across the western Pyrenees and defeated the Aquitanian duke, who in turn appealed to the Frankish leader Charles Martel for assistance, offering to place himself under Carolingian sovereignty. At the Battle of Poitiers in 732, the al-Andalus raiding army was defeated by Charles Martel. In 734, the Andalusi launched raids to the east, capturing Avignon and Arles and overran much of Provence. In 737, they traveled up the Rhône valley, reaching as far north as Burgundy. Charles Martel of the Franks, with the assistance of Liutprand of the Lombards, invaded Burgundy and Provence and expelled the raiders by 739.

Relations between Arabs and Berbers in al-Andalus had been tense in the years after the conquest. Berbers, heavily outnumbering the Arabs in the province, had done the bulk of the fighting, and were assigned the harsher duties (e.g., garrisoning the more troubled areas). Although some Arab governors had cultivated their Berber lieutenants, others had grievously mistreated them. Mutinies by Berber soldiers were frequent; e.g., in 729, the Berber commander Munnus had revolted and managed to carve out a rebel state in Cerdanya for a while.

In 740, a Berber Revolt erupted in the Maghreb (North Africa). To put down the rebellion, the Umayyad Caliph Hisham dispatched a large Arab army, composed of regiments (''Junds'') of Bilad Ash-Sham, to North Africa. But the great Umayyad army was crushed by the Berber rebels at the Battle of Bagdoura (in Morocco). Heartened by the victories of their North African brethren, the Berbers of al-Andalus quickly raised their own revolt. Berber garrisons in the north of the Iberian Peninsula mutinied, deposed their Arab commanders, and organized a large rebel army to march against the strongholds of Toledo, Cordoba, and Algeciras.

In 741, Balj b. Bishr led a detachment of some 10,000 Arab troops across the straits. The Arab governor of al-Andalus, joined by this force, crushed the Berber rebels in a series of ferocious battles in 742. However, a quarrel immediately erupted between the Syrian commanders and the Andalusi, the so-called "original Arabs" of the earlier contingents. The Syrians defeated them at the hard-fought Battle of Aqua Portora in August 742 but were too few to impose themselves on the province.

The quarrel was settled in 743 when Abū l-Khaṭṭār al-Ḥusām, the new governor of al-Andalus, assigned the Syrians to regimental fiefs across al-Andalus the Damascus jund was established in Elvira ( Granada), the Jordan jund in Rayyu ( Málaga and Archidona), the Jund Filastin in Medina-Sidonia and Jerez, the Emesa (Hims) jund in Seville and Niebla, and the Qinnasrin jund in Jaén. The Egypt jund was divided between Beja ( Alentejo) in the west and Tudmir (Murcia) in the east. The arrival of the Syrians substantially increased the Arab element in the Iberian peninsula and helped strengthen the Muslim hold on the south. However, at the same time, unwilling to be governed, the Syrian ''junds'' carried on an existence of autonomous feudal anarchy, severely destabilizing the authority of the governor of al-Andalus.

A second significant consequence of the revolt was the expansion of the Kingdom of the Asturias, hitherto confined to enclaves in the Cantabrian highlands. After the rebellious Berber garrisons evacuated the northern frontier fortresses, the Christian king Alfonso I of Asturias set about immediately seizing the empty forts for himself, quickly adding the northwestern provinces of Galicia and León to his fledgling kingdom. The Asturians evacuated the Christian populations from the towns and villages of the Galician-Leonese lowlands, creating an empty buffer zone in the Douro River valley (the "Desert of the Duero"). This newly emptied frontier remained roughly in place for the next few centuries as the boundary between the Christian north and the Islamic south. Between this frontier and its heartland in the south, the al-Andalus state had three large march territories (''thughur''): the Lower March (capital initially at Mérida, later Badajoz), the Middle March (centered at Toledo), and the Upper March (centered at Zaragoza).

These disturbances and disorders also allowed the Franks, now under the leadership of Pepin the Short, to invade the strategic strip of Septimania in 752, hoping to deprive al-Andalus of an easy launching pad for raids into Francia. After a lengthy siege, the last Arab stronghold, the citadel of Narbonne, finally fell to the Franks in 759. Al-Andalus was sealed off at the Pyrenees.

The third consequence of the Berber revolt was the collapse of the authority of the Damascus Caliphate over the western provinces. With the Umayyad Caliphs distracted by the challenge of the Abbasids in the east, the western provinces of the Maghreb and al-Andalus spun out of their control. From around 745, the Fihrids, an illustrious local Arab clan descended from Oqba ibn Nafi al-Fihri, seized power in the western provinces and ruled them almost as a private family empire of their own Abd al-Rahman ibn Habib al-Fihri in Ifriqiya and Yūsuf al-Fihri in al-Andalus. The Fihrids welcomed the fall of the Umayyads in the east, in 750, and sought to reach an understanding with the Abbasids, hoping they might be allowed to continue their autonomous existence. But when the Abbasids rejected the offer and demanded submission, the Fihrids declared independence and, probably out of spite, invited the deposed remnants of the Umayyad clan to take refuge in their dominions. It was a fateful decision that they soon regretted, for the Umayyads, the sons and grandsons of caliphs, had a more legitimate claim to rule than the Fihrids themselves. Rebellious-minded local lords, disenchanted with the autocratic rule of the Fihrids, conspired with the arriving Umayyad exiles.

Umayyad Emirate of Córdoba

Establishment

In 755, the exiled Umayyad prince Abd al-Rahman I (also called ''al-Dākhil'', the 'Immigrant') arrived on the coast of Spain. He had fled the Abbasids, who had overthrown the Umayyads in Syria and were slaughtering members of that family, and then he spent four years in exile in North Africa, assessing the political situation in al-Andalus across the Straits of Gibraltar, before he landed at Almuñécar.

News of his arrival spread across al-Andalus, and when word reached its governor, Yūsuf al-Fihri, he was not pleased. During this time, Abd al-Rahman and his supporters quickly conquered Málaga and then Seville, finally besieging the capital of al-Andalus, Córdoba. Abd al-Rahman's army was exhausted after their conquest, meanwhile Governor Yūsuf al-Fihri had returned from quashing another rebellion with his army. The siege of Córdoba began, and noticing the starving state of Abd al-Rahman's army, al-Fihri began throwing lavish feasts every day as the siege went on, to tempt Abd al Rahman's supporters to defect to his side. However, Abd al-Rahman persisted, even rejecting a truce that would have allowed Abd al-Rahman to marry al-Fihri's daughter. After decisively defeating Yūsuf al-Fihri's army, Abd al-Rahman was able to conquer Córdoba, where he proclaimed himself emir in 756. The rest of Iberia was easily conquered, and Abd al-Rahman soon had control of all of Iberia.

Rule

Abd al Rahman's rule was stable in the years after his conquest – he built major public works, most famously the Mosque of Córdoba, and helped urbanize the emirate while defending it from invaders, including the quashing of numerous rebellions, and decisively repelling the invasion by Charlemagne (which would later inspire the epic, Chanson de Roland). By far the most important of these invasions was the attempted reconquest by the Abbasid Caliphate. In 763 Caliph Al-Mansur of the Abbasids installed al-Ala ibn-Mugith as governor of Africa (whose title gave him dominion over the province of al-Andalus). He planned to invade and destroy the Emirate of Córdoba, so in response Abd al Rahman fortified himself within the fortress of Carmona with a tenth as many soldiers as al-Ala ibn-Mugith]. After a long siege, it appeared that Abd al Rahman would be defeated, but in a last stand Abd al Rahman with his outnumbered forces opened the gates of the fortress and charged at the resting Abbasid army, and decisively defeated them. After being sent the embalmed head of al-Ala ibn-Mugith], it is said Al Mansur exclaimed "Praise be to God who has put the sea between me and this devil!".

Abd al Rahman I died in 788 after a lengthy and prosperous reign. He was succeeded by his son, Hisham I of Córdoba, Hisham I, who secured power of exiling his brother who had tried to rebel against him. Hisham enjoyed a stable reign of eight years and was succeeded by his son Al-Hakam I. The next few decades were relatively uneventful, with only occasional minor rebellions, and saw the rise of the emirate. In 822 Al Hakam died and was succeeded by Abd al-Rahman II, the first great emir of Córdoba. He rose to power with no opposition and sought to reform the emirate. He quickly reorganized the bureaucracy to be more efficient and built many mosques across the emirate. During his reign science and art flourished, as many scholars fled the Abbasid caliphate due to the disastrous Fourth Fitna. The scholar Abbas ibn Firnas made an attempt to flee, though accounts vary on his success. In 852 Abd al Rahman II died, leaving behind him a powerful and well-established state that had become one of the most powerful in the Mediterranean.

Abd al Rahman was succeeded by Muhammad I of Córdoba, who according to legend had to wear women's clothing to sneak into the imperial palace and be crowned, since he was not the heir apparent. His reign marked a decline in the emirate, which was ended by Abd al-Rahman III. His reign was marked by multiple rebellions, which were dealt with poorly and weakened the emirate, most disastrously following the rebellion of Umar ibn Hafsun. When Muhammad died, he was succeeded by emir Abdullah ibn Muhammad al-Umawi whose power barely reached outside of the city of Córdoba. As Ibn Hafsun ravaged the south, Abdullah did almost nothing, and slowly became more and more isolated, barely speaking to anyone. Abdullah purged his administration of his brothers, which lessened the bureaucracy's loyalty towards him. Around this time several local Arab lords began to revolt, including one Kurayb ibn Khaldun, who was able to conquer Seville. Some loyalists tried to quell the rebellion, but without proper material support, their efforts were in vain.

He declared that the next emir would be his grandson Abd al-Rahman III, ignoring the claims of his four living children. Abdullah died in 912, and the throne passed to Abd al Rahman III. Through force of arms and diplomacy, he put down the rebellions that had disrupted his father's reign, obliterating Ibn Hafsun and hunting down his sons. After this he led several sieges against the Christians, sacking the city of Pamplona, and restoring some prestige to the emirate. Meanwhile, across the sea the Fatimids had risen up in force, ousted the Abbasid government in North Africa, and declared themselves a caliphate. Inspired by this action, Abd al Rahman joined the rebellion and declared himself caliph in 929.

Umayyad Caliphate of Córdoba

The period of the Caliphate is seen as the golden age of al-Andalus. Crops produced using irrigation, along with food imported from the Middle East, provided the area around Córdoba and some other ''Andalusī'' cities with an agricultural economic sector that was the most advanced in Europe by far, sparking the Arab Agricultural Revolution. Among European cities, Córdoba under the Caliphate, with a population of perhaps 500,000, eventually overtook Constantinople as the largest and most prosperous city in Europe.Chandler, Tertius. ''Four Thousand Years of Urban Growth: An Historical Census'' (1987), St. David's University Press
etext.org
). . Within the Islamic world, Córdoba was one of the leading cultural centres. The work of its most important philosophers and scientists (notably Abulcasis and Averroes) had a major influence on the intellectual life of medieval Europe.

Muslims and non-Muslims often came from abroad to study at the famous libraries and universities of al-Andalus, mainly after the reconquest of Toledo in 1085 and the establishment of translation institutions such as the Toledo School of Translators. The most noted of those was Michael Scot (c. 1175 to c. 1235), who took the works of Ibn Rushd ("Averroes") and Ibn Sina ("Avicenna") to Italy. This transmission of ideas significantly affected the formation of the European Renaissance.Perry, Marvin; Myrna Chase, Margaret C. Jacob, James R. Jacob
''Western Civilization: Ideas, Politics, and Society''
(2008), 903 pages, pp. 261–262.

The Caliphate of Cordoba also had extensive trade with other parts of the Mediterranean, including Christian parts. Trade goods included luxury items (silk, ceramics, gold), essential foodstuffs (grain, olive oil, wine), and containers (such as ceramics for storing perishables). In the tenth century, Amalfitans were already trading Ifriqiyan and Byzantine silks in Umayyad Cordoba. Later references to Amalfitan merchants were sometimes used to emphasize the previous golden age of Cordoba. Fatimid Egypt was also a supplier of luxury goods, including elephant tusks, and raw or carved crystals. The Fatimids were traditionally thought to be the only supplier of such goods but were also valuable connections to Ghana. Control over these trade routes was a cause of conflict between Umayyads and Fatimids.

''Taifas'' period

The Caliphate of Córdoba effectively collapsed during a ruinous civil war between 1009 and 1013, although it was not finally abolished until 1031 when ''al-Andalus'' broke up into a number of mostly independent mini-states and principalities called ''taifas''. In 1013, invading Berbers sacked Córdoba, massacring its inhabitants, pillaging the city, and burning the palace complex to the ground. The largest of the taifas to emerge were Badajoz (''Batalyaws''), Toledo (''Ṭulayṭulah''), Zaragoza (''Saraqusta''), and Granada (''Ġarnāṭah''). After 1031, the ''taifas'' were generally too weak to defend themselves against repeated raids and demands for tribute from the Christian states to the north and west, which were known to the Muslims as "the Galician nations", and which had spread from their initial strongholds in Galicia, Asturias, Cantabria, the Basque country, and the Carolingian '' Marca Hispanica'' to become the Kingdoms of Navarre, León, Portugal, Castile and Aragon, and the County of Barcelona. Eventually raids turned into conquests, and in response the ''Taifa'' kings were forced to request help from the Almoravids, Muslim Berber rulers of the Maghreb. Their desperate maneuver would eventually fall to their disadvantage, however, as the Almoravids they had summoned from the south went on to conquer and annex all the ''Taifa'' kingdoms.
During the eleventh century several centers of power existed among the taifas, and the political situation shifted rapidly. Before the rise of the Almoravids from the south or the Christians from the north, the Abbadid-ruled Taifa of Seville succeeded in conquering a dozen lesser kingdoms, becoming the most powerful and renowned of the taifas, such that it could have laid claim to be the true heir to the Caliphate of Cordoba. The taifas were vulnerable and divided but had immense wealth. During its prominence the Taifa of Seville produced technically complex lusterware and exerted significant influence on ceramic production across al-Andalus.

Almoravids, Almohads, and Marinids

In 1086 the Almoravid ruler of Morocco, Yusuf ibn Tashfin, was invited by the Muslim princes in Iberia to defend them against Alfonso VI, King of Castile and León. In that year, Tashfin crossed the straits to Algeciras and inflicted a severe defeat on the Christians at the Battle of Sagrajas. By 1094, ibn Tashfin had removed all Muslim princes in Iberia and had annexed their states, except for the one at Zaragoza. He also regained Valencia from the Christians. The city-kingdom had been conquered and ruled by El Cid at the end of its second taifa period. The Almoravid dynasty made its capital in Marrakesh, from which it ruled its domains in al-Andalus. Modern scholarship has sometimes admitted originality in North African architecture, but according to Yasser Tabbaa, historian of Islamic art and architecture, the Iberocentric viewpoint is anachronistic when considering the political and cultural environment during the rule of the Almoravid dynasty. The rise and fall of the Almoravids is sometimes seen as an expression of Ibn Khaldun's asabiyyah paradigm.

The Almoravids were succeeded by the Almohads, another Berber dynasty, after the victory of Abu Yusuf Ya'qub al-Mansur over the Castilian Alfonso VIII at the Battle of Alarcos in 1195. In 1212, a coalition of Christian kings under the leadership of the Castilian Alfonso VIII defeated the Almohads at the Battle of Las Navas de Tolosa. The Almohads continued to rule Al-Andalus for another decade, though with much reduced power and prestige. The civil wars following the death of Abu Ya'qub Yusuf II rapidly led to the re-establishment of taifas. The taifas, newly independent but now weakened, were quickly conquered by Portugal, Castile, and Aragon. After the fall of Murcia (1243) and the Algarve (1249), only the Emirate of Granada remained as a Muslim state in Iberia, tributary of Castile until 1492. Most of its tribute was paid in gold that was carried to Iberia from present-day Mali and Burkina Faso through the merchant routes of the Sahara.

The last Muslim threat to the Christian kingdoms was the rise of the Marinids in Morocco during the 14th century. They took Granada into their sphere of influence and occupied some of its cities, like Algeciras. However, they were unable to take Tarifa, which held out until the arrival of the Castilian Army led by Alfonso XI. The Castilian king, with the help of Afonso IV of Portugal and Peter IV of Aragon, decisively defeated the Marinids at the Battle of Río Salado in 1340 and took Algeciras in 1344. Gibraltar, then under Granadian rule, was besieged in 1349–50. Alfonso XI and most of his army perished by the Black Death. His successor, Peter of Castile, made peace with the Muslims and turned his attention to Christian lands, starting a period of almost 150 years of rebellions and wars between the Christian states that secured the survival of Granada.

Emirate of Granada, its fall, and aftermath

From the mid 13th to the late 15th century, the only remaining domain of al-Andalus was the Emirate of Granada, the last Muslim stronghold in the Iberian Peninsula. The emirate was established by Muhammad ibn al-Ahmar in 1230 and was ruled by the Nasrid dynasty, the longest reigning dynasty in the history of al-Andalus. Although surrounded by Castilian lands, the emirate was wealthy through being tightly integrated in Mediterranean trade networks and enjoyed a period of considerable cultural and economic prosperity.

However, for most of its existence Granada was a tributary state, with Nasrid emirs paying tribute to Castilian kings. Granada's status as a tributary state and its favorable geographic location, with the Sierra Nevada as a natural barrier, helped to prolong Nasrid rule and allowed the emirate to prosper as a regional entrepôt with the Maghreb and the rest of Africa. The city of Granada also served as a refuge for Muslims fleeing during the Reconquista, accepting numerous Muslims expelled from Christian controlled areas, doubling the size of the city and even becoming one of the largest in Europe throughout the 15th century in terms of population. The independent Nasrid kingdom was also a trade hub between the Atlantic and Mediterranean, and was frequented especially by Genoese merchants.

In 1469, the marriage of Ferdinand of Aragon and Isabella of Castile signaled the launch of the final assault on the emirate. The King and Queen convinced Pope Sixtus IV to declare their war a crusade. The Catholic Monarchs crushed one center of resistance after another until finally on January 2, 1492, after a long siege, the emirate's last sultan Muhammad XII surrendered the city and the fortress palace, the renowned Alhambra (see Fall of Granada).

By this time Muslims in Castile numbered half a million. After the fall, "100,000 had died or been enslaved, 200,000 emigrated, and 200,000 remained as the residual population. Many of the Muslim elite, including Muhammad XII, who had been given the area of the Alpujarras mountains as a principality, found life under Christian rule intolerable and passed over into North Africa." Under the conditions of the Capitulations of 1492, the Muslims in Granada were to be allowed to continue to practice their religion.

Mass forced conversions of Muslims in 1499 led to a revolt that spread to Alpujarras and the mountains of Ronda; after this uprising the capitulations were revoked. In 1502 the Catholic Monarchs decreed the forced conversion of all Muslims living under the rule of the Crown of Castile, although in the kingdoms of Aragon and Valencia (both now part of Spain) the open practice of Islam was allowed until 1526. Descendants of the Muslims were subject to expulsions from Spain between 1609 and 1614 (see Expulsion of the Moriscos).
The last mass prosecution against Moriscos for crypto-Islamic practices occurred in Granada in 1727, with most of those convicted receiving relatively light sentences. From then on, indigenous Islam is considered to have been extinguished in Spain.

Science

There were many scientific advances, especially in the fields of medicine, astronomy, and agronomy in Al-Andalus. Córdoba served as a major center for this scientific growth, with a vast amount of these advancements occurring during the rule of ‘Abd al-Rahman III from 929 to 961, in part due to the exposure of scientists to translations of older Greek and Persian works during that time. Scholars often worked in many different and overlapping subjects, so it is difficult to place those discussed here into a single scientific field each.

Medicine

Notable surgeons, physicians, and medical scholars from al-Andalus include Ibn al-Baytar (d. 1248), Abu al-Qasim al-Zahrawi (Albucasis; d. 1013), Muhammad al-Shafrah (d. 1360), Abu Marwan 'Abd al-Malik ibn Habib (d. 853), and Abu Marwan ibn Zuhr (Avenzoar; d. 1162). Of particular note is al-Zahrawi, who is considered by many to be "probably the greatest physician in the entire history of Western Islam." Around the year 1000 C.E, he wrote a book with a title that roughly translates to ''The Arrangement of Medical Knowledge for One Who is Not Able to Compile a Book for Himself'' (''Kitab al-tasrif li-man 'ajiza 'an al-ta'alif'')—a comprehensive medical encyclopedia with the goal of summarizing all existing medical knowledge and eliminating the need for students and practitioners to rely on multiple medical texts. The book is renowned for its chapter on surgery which included important illustrations of surgical instruments, as well as sections "on cauterization, on incisions, venesection and wounds, and on bone-setting." For hundreds of years after its publication it was one of the most widely used medical texts for students and medical practitioners and was translated into Hebrew, Latin, and Castilian. This encyclopedia is also significant for its inclusion of al-Zahrawi's personal experiences as a surgeon, which provided important case studies for aspiring surgeons. This distinguishes it from other strictly factual medical works of the time, most notably Ibn Sina's ''Canon of Medicine''.

Other important medical texts include al-Baytar's ''Comprehensive Book on Simple Drugs and Foodstuffs—''an encyclopedia with descriptions of the medical uses of over 1400 plants and other types of medicine—and ibn Habib's ''Book of the Medicine of the Arabs'' (''Kitab tibb al-'arab'')—a historical summary of Arabic medicine until the 9th century''.'' Ibn Habib's work is significant because it is one of the oldest known writings in the field of prophetic medicine, which uses hadiths to create Islamic-based medicinal guidelines. His book is also significant because it uses principles of Galenic medicine, such as humorism and the theory of four temperaments, as the basis of its medical recommendations.

The ibn Zuhr family played a very important role in the production of Andalusi medical knowledge, as they produced five generations of medical experts, particularly in the fields of dietary sciences and medicaments. Abu Marwan ibn Zuhr (d. 1162) is particularly notable, as he wrote the ''Book of Moderation'' (''Kitab al-Iqtisad'')—a treatise on general therapy; the ''Book of Foods'' (''Kitab al-Aghdhiya'')—a manual on foods and regimen which contains guidelines for a healthy life; and the ''Kitab al-Taysir''—a book written to act as a compendium to Ibn Rushd's Colliget. In ''Kitab al-Taysir'' he provides one of the earliest clinical descriptions of the scabies mite.

Astronomy

Three of the most notable Andalusi astronomers were Ibn Tufail (d. 1185), Ibn Rushd (Averroes; d. 1198), and Nur ad-Din al-Bitruji (Alpetragius; d. 1204). All lived around the same time and focused their astronomical works on critiquing and revising Ptolemaic astronomy and the problem of the equant in his astronomical model. Instead, they accepted Aristotle's model and promoted the theory of homocentric spheres.

Al-Bitruji is believed to have studied under Ibn Tufail and Bitruji's ''Book on Cosmology'' (''Kitab fi al-hay'a'') built on Ibn Tufail's work, as well as that of Ibn Rushd, Ibn Bajja, and Maimonides. The book's goal was "to overcome the physical difficulties inherent in the geometrical models of Ptolemy's '' Almagest'' and to describe the cosmos in agreement with Aristotelian or Neoplatonic physics," which it succeeded in doing to an extent. Bitruji's book set a precedent of criticizing the ''Almagest'' in future works in the field of astronomy.

Although Ibn Rushd originally trained and practiced as a jurist, he was exposed to astronomy—possibly through Ibn Tufail—and became a renowned scientist in the field. His most popular work was his ''Summary of the Almagest'', but he also published shorter works discussing Aristotle's planetary theories''.'' Ibn Rushd published writings on philosophy, theology, and medicine throughout his life too, including commentaries on the works of Ibn Sina.

In addition to writing the important ''Book of the Medicine of the Arabs'', Ibn Habib also wrote the ''Book on Stars'' (''Kirab fi l-nujim''). This book included important "teachings on the lunar mansions, the signs of the zodiac, ndthe division of the seasons." In these teachings, Ibn-Habib calculated the phases of the moon and dates of the annual solstices and equinoxes with relative accuracy.

Another important astronomer from al-Andalus was Maslama al-Majriti (d. 1007), who played a role in translating and writing about Ptolemy's ''Planisphaerium'' and ''Almagest''. He built on the work of older astronomers, like Muhammad ibn Musa al-Khwarizmi, whose astronomical tables he wrote a discussion on and subsequently improved.

Abu Ishaq Ibrahim al-Zarqali (d. 1087) had many influential astronomical successes, as shown by Copernicus's recognition of him in his ''On the Revolutions of the Heavenly Spheres'' five centuries later. Along with other astronomers, he undertook extensive work to edit the Toledan Zij astronomical tables. He also accurately calculated the motion of the solar apogee to be 12.04 seconds per year, which is relatively close to today's calculation of 11.8 seconds per year.

Agronomy

Other important scientific advances in al-Andalus occurred in the field of agronomy. These advances were in part facilitated by technological innovations in irrigation systems. State organized, large-scale irrigation projects provided water to city baths, mosques, gardens, residential homes, and governing palaces, such as the al-Hambra and its gardens in Granada. Collective, peasant-built irrigation infrastructure also played an important role, especially in agriculture. Many of these irrigation techniques, especially those utilized by peasants, were brought to al-Andalus by migrating Berber and Arab tribes. Although some irrigation projects built on existing Roman infrastructure, most of al-Andalus's irrigation systems were new projects built separate from old Roman aqueducts. However, there is some debate about this among scholars.

One notable agriculturalist was Ibn al-'Awwam, who wrote the ''Book of Agriculture''. This book contains 34 chapters about various aspects of agriculture and animal husbandry, including discussions of over 580 different types of plants and how to treat plant diseases.

Other agronomic innovations in al-Andalus include the cultivation of the pomegranate from Syria, which has since become the namesake and ubiquitous symbol of the city of Granada, as well as the first attempt to create a botanical garden near Córdoba by ‘ Abd al-Rahman I.

Culture

Religion

The society of al-Andalus was made up of three main religious groups: Muslims, Christians, and Jews. The Muslims, although united on the religious level, had several ethnic divisions, mainly the distinction between the Arabs and the Berbers. The Arab elite regarded non-Arab Muslims as second-class citizens and particularly scorned the Berbers.

The ethnic structure of al-Andalus consisted of Arabs at the top of the social scale, followed by, in descending order, Berbers, Muwalladûn, Mozarabes, and Jews. Each of the communities inhabited distinct neighborhoods in the cities. In the 10th century, a massive conversion of Christians took place, and ''muladies'' (Muslims of native Iberian origin), formed the majority of Muslims. The Muwalladûn had spoken in a Romance dialect of Latin called Mozarabic, but they increasingly adopted Arabic, which eventually evolved into Andalusi Arabic in which Muslims, Jews and Christians had become monolingual in the last surviving Muslim state in the Iberian Peninsula, the Emirate of Granada (1230–1492). Eventually, the Muladies and later the Berber tribes adopted an Arabic identity, like the majority of subject people in Egypt, the Levant, Mesopotamia, and North Africa. Muladies, together with other Muslims, had comprised 80% of the population of al-Andalus by 1100.
Mozarabs were Christians who had long lived under Muslim and Arab rule and adopted many Arab customs, art and words, but they maintained their religion, Latin rituals and Romance languages.

The Jewish population worked mainly as tax collectors, in trade, or as doctors or ambassadors. In the late 15th century, there were about 50,000 Jews in Granada and roughly 100,000 in the whole of Islamic Iberia.

Non-Muslims were given the status of '' ahl al-dhimma'' (people under protection), with adult men paying a " Jizya" tax equal to one dinar per year with exemptions for the elderly and the disabled. Those who were neither Christians nor Jews, such as pagans, were given the status of ''Majus''. The treatment of non-Muslims in the Caliphate has been a subject of considerable debate among scholars and commentators, especially those interested in drawing parallels to the co-existence of Muslims and non-Muslims in the modern world.

Jews constituted more than five percent of the population. Al-Andalus was a key centre of Jewish life during the early Middle Ages, produced important scholars and was one of the most stable and wealthy Jewish communities.

The longest period of relative tolerance began after 912, with the reign of Abd-ar-Rahman III and his son, Al-Hakam II, and the Jews of al-Andalus prospered by devoting themselves to the service of the Caliphate of Córdoba the study of the sciences; and to commerce and industry, especially by trading in silk and slaves, which thus promoted the prosperity of the country. Southern Iberia became an asylum for the oppressed Jews of other countries.

Under the Almoravids and the Almohads, there may have been intermittent persecution of Jews, but sources are extremely scarce and do not give a clear picture though the situation appears to have deteriorated after 1160. Muslim pogroms against Jews in al-Andalus occurred in Córdoba (1011) and in Granada (1066).Frederick M. Schweitzer, Marvin Perry., ''Anti-Semitism: myth and hate from antiquity to the present'', Palgrave Macmillan, 2002, , pp. 267–268. However, massacres of ''dhimmis'' are believed to be rare in Islamic history.

far surpassed the Almoravides in fundamentalist outlook, and treated the non-Muslim harshly. Faced with the choice of either death or conversion, many Jews and Christians emigrated.Frank and Leaman, 2003, pp. 137–138. Some, such as the family of Maimonides, fled east to more tolerant Muslim lands.

Many ethnicities and religions co-existed in al-Andalus, each of which contributed to its intellectual prosperity. Literacy in Islamic Iberia was far more widespread than in many other nations in the West of the time.

In the 11th century, the Hindu-Arabic numeral system (base 10) had reached Europe via Al-Andalus through Spanish Muslis, together with knowledge of astronomy and instruments like the astrolabe, which was first imported by Gerbert of Aurillac. For that reason, the numerals came to be known in Europe as Arabic numerals despite their origins in India.

From the earliest days, the Umayyads wanted to be seen as intellectual rivals to the Baghdad
