Al-Andalus () refers to the various Muslim ruled territories on the Iberian Peninsula that existed between 711 and 1492. At its height, it covered the entirety of Spain and Portugal, as well as parts of southern France. The name refers to the different Muslim states that controlled these territories at various times between 711 and 1492. At its greatest geographical extent, it occupied most of the peninsula as well as Septimania under Umayyad rule. These boundaries changed through a series of conquests that Western historiography has traditionally characterised as the Reconquista,"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"), García de Cortázar, José Ángel.

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 (–929); the Caliphate of Córdoba (929–1031); the first taifa kingdoms (1009–1110); the Almoravid Empire (1085–1145); the second taifa period (1140–1203); the Almohad Caliphate (1147–1238); the third taifa period (1232–1287); and ultimately the Nasrid Emirate of Granada (1238–1492). Under the Caliphate of Córdoba, the city of Córdoba became one of the leading cultural and economic centres of the Mediterranean Basin, Europe, and the Islamic world. Achievements that advanced Islamic and Western science came from al-Andalus, including major advances in trigonometry (Jabir ibn Aflah), astronomy (al-Zarqali), surgery (al-Zahrawi), pharmacology (Ibn Zuhr), and agronomy (Ibn Bassal and Abu'l-Khayr al-Ishbili). Al-Andalus became a conduit for cultural and scientific exchange between the Islamic and Christian worlds.

For much of its history, al-Andalus existed in conflict with Christian kingdoms to the north. After the fall of the Umayyad Caliphate of Cordoba by 1031, al-Andalus was fragmented into taifa states and principalities, some of which (such as the Taifa of Toledo, the Taifa of Zaragoza, the Taifa of Seville and the Taifa of Badajoz) reached considerable territorial extent. After the Christian capture of Toledo in 1085, the Almoravid empire intervened and repelled attacks on the region, then brought al-Andalus under direct Almoravid rule. For the next century and a half, al-Andalus became a province of the Muslim empires of the Almoravids and their successors, the Almohads, both based in Marrakesh.

Ultimately, the northern Christian kingdoms overpowered the Muslim states to the south. In the 13th century, most of the south quickly fell under Christian rule, with Gharb al-Andalus, the Guadalquivir Valley and Eastern al-Andalus falling to Portuguese, Castilian, and Aragonese conquests. This left the Emirate of Granada as the remaining Muslim state on the Iberian Peninsula, which became a tributary state of the Crown of Castile, before surrendering in 1492 to the Catholic Monarchs.

Etymology

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, vândalos in Portuguese).

Since the 1980s, several alternative etymologies 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 commander Tariq ibn-Ziyad led an army of 7,000 that landed at Gibraltar on 30 April 711, ostensibly to intervene in a Visigothic civil war. After a decisive victory over King Roderic at the Battle of Guadalete on 19 July 711, Tariq, accompanied by his mawla, 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 organised 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.

Following the Muslim conquest of Spain, al-Andalus, then at its greatest extent, was divided into five administrative units, corresponding very roughly to: modern Andalusia; Castile and León; Navarre, Aragon, and Catalonia; Portugal and Galicia; and the Languedoc-Roussillon area of Occitania.

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 recognise 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 decisively defeated by Duke Odo the Great of Aquitaine at the Battle of Toulouse (721). However, after crushing Odo's Berber ally Uthman ibn Naissa in 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 and Al Ghafiqi was killed. In 734, the Andalusi launched raids to the east, capturing Avignon and Arles, and overran much of Provence. In 737, they travelled 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.

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) from Bilad Ash-Sham,Specifically, the army of 27,000 troops comprised 6,000 men from each of the four main junds of Jund Dimashq (Damascus), Jund Hims (Homs), Jund al-Urdunn (Jordan), and Jund Filastin (Filastin), plus 3,000 from Jund Qinnasrin. An additional 3,000 were recruited in Egypt. See R. Dozy (1913) Spanish Islam: A History of the Muslims in Spain (translated by Francis Griffin Stokes from Dozy's original (1861) French Histoire des Musulmans d'Espagne, with consultation of the 1874 German version and the 1877 Spanish version) Chatto & Windus, London, page 133 to North Africa. This Umayyad army was defeated 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 organised a large rebel army to march against the strongholds of Toledo, Córdoba, and Algeciras.

In 741, Balj bin Bishr led a detachment of some 10,000 Arab troops across the straits. The Arab governor of al-Andalus, joined by this force, was victorious over the Berber rebels in a series of battles in 742. A dispute 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 (Palestine) 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 destabilising 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. On the Muslim side of the frontier, al-Andalus had three large march territories (thaghr, pl. thughūr): the Lower March (capital at Mérida and Badajoz, featuring a population primarily of Berber and Muwallad stock), the Middle March (centred at Toledo, primarily muwallad), and the Upper March (centred at Zaragoza, with a more intricate ethnic mix and a more substantial population of Arab stock as well as maintaining more complex relations with its Carolingian and Navarrese neighbours).

These disturbances and disorder 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.Cardini, Franco.
