Capture of Toledo (1085): Alfonso VI Takes a Great Moorish City

The capture of Toledo on 25 May 1085 was the moment King Alfonso VI of León and Castile took possession of Toledo, a great city of Muslim Spain and the former capital of the Visigothic kingdom. It was the first major city of al-Andalus to pass to the Christian kingdoms of the north, and its fall shifted the balance of power in the Iberian Peninsula. Toledo went on to become a centre where Arabic learning was translated into Latin, with lasting effects on European science and philosophy.

Background: Toledo and the taifa kingdoms

Toledo stands on a rocky hill almost encircled by the River Tagus. It had been the royal seat of the Visigoths until the Muslim conquest of 711. Under Muslim rule it became a large, prosperous and often rebellious city, home to Muslims, Arabic-speaking Christians known as Mozarabs, and a significant Jewish community.

In the early eleventh century the Caliphate of Córdoba collapsed, and by 1031 al-Andalus had broken up into rival states known as taifas. Toledo became the centre of one of the largest, ruled by the Dhu’l-Nunid dynasty. The taifas were rich but militarily weak, and many paid regular tribute, called parias, to Christian kings in exchange for protection.

Alfonso VI had personal ties to Toledo. In 1072, after losing a war against his brother Sancho II, he lived for some months as an exile at the court of Toledo’s ruler, al-Ma’mun. Later that year Sancho was murdered, and Alfonso became king of both León and Castile.

The road to surrender

Al-Ma’mun died in 1075 and was succeeded by his grandson Yahya al-Qadir, an unpopular and ineffective ruler. Toledo was torn by factions, and in about 1080 a revolt drove al-Qadir from the city. Alfonso helped restore him, in return for heavy payments and, according to many historians, an understanding that Toledo would eventually be handed over.

From the early 1080s Alfonso’s armies raided the lands around Toledo, destroying crops and cutting off supplies. By 1084 the city was under blockade. Its leaders sought help from other taifas, but little came.

At last al-Qadir agreed to surrender. In return, Alfonso promised to help him gain the kingdom of Valencia, which al-Qadir later ruled under Castilian protection. Alfonso entered Toledo on 25 May 1085. The city had been taken by pressure and diplomacy rather than by storm.

Terms of the surrender

According to the surviving accounts, the terms were generous. Muslims who wished to leave could take their movable goods; those who stayed kept their homes and property, paid the same taxes as before, and could continue to worship in their mosques, including the main mosque.

The last promise did not last. In 1086, while the king was away, the new archbishop, Bernard of Sédirac, a French monk from Cluny, took over the great mosque with the support of Queen Constance and consecrated it as a cathedral. Chroniclers later said Alfonso was angry, but the change stood. Over the following generations many Muslims left, while settlers from the north and from France moved in.

Alfonso, who already used grand imperial titles, now styled himself ruler of Toledo and claimed leadership over all of Spain. In 1088 Pope Urban II confirmed the archbishop of Toledo as primate of the Spanish Church, reviving the city’s old Visigothic religious role.

A mixed city under Castilian rule

Christian Toledo kept much of its Islamic character for generations. Arabic remained a language of daily life, contracts and even some church business among the Mozarabs, who were granted their own legal privileges by Alfonso VI in 1101. Craftsmen continued to build in Islamic styles, producing the brick and horseshoe-arch architecture later called Mudéjar.

Muslims who stayed, known as Mudéjars, lived under Christian rule with their own leaders and laws, as did the city’s Jewish community, which became one of the most important in Castile. Toledo’s synagogues, such as the building now called Santa María la Blanca, date from this later period. Relations between the communities were often uneasy and changed over time, but for several centuries the city remained a place where three faiths and several languages met.

Consequences: the Almoravids arrive

The fall of Toledo shocked the other taifa rulers. Seville, Badajoz and Granada, fearing they would be next, turned for help to the Almoravids, a powerful Berber movement that had built an empire in Morocco. Their leader, Yusuf ibn Tashfin, crossed the Strait of Gibraltar in 1086.

On 23 October 1086 the Almoravids and their Andalusi allies defeated Alfonso at the Battle of Sagrajas, known in Arabic as al-Zallaqa, near Badajoz. Over the following years the Almoravids deposed most of the taifa kings and made al-Andalus part of their own empire.

Toledo itself held out. It withstood Almoravid attacks, including a siege in 1109 shortly after Alfonso’s death, and stayed in Christian hands. It became a frontier stronghold and later one of the main cities of the Crown of Castile. Alfonso’s former commander Rodrigo Díaz, El Cid, took Valencia in 1094 during the same era of shifting alliances.

A city of translators

The most lasting result of 1085 was cultural. Toledo kept many Arabic manuscripts and a population able to read Arabic, Hebrew and Latin. From the twelfth century, encouraged by Archbishop Raymond (1125-1152) and later churchmen, scholars began translating Arabic texts into Latin.

The most productive was Gerard of Cremona (c. 1114-1187), who came to Toledo to find Ptolemy’s Almagest and translated dozens of works on astronomy, mathematics, medicine and philosophy, including Avicenna’s Canon of Medicine. Others, such as Dominicus Gundissalinus, translated philosophy, often with help from Jewish or Mozarab collaborators. In the thirteenth century King Alfonso X sponsored translations into Castilian.

Historians sometimes call this activity the “Toledo School of Translators”, but the label dates from the nineteenth century. There was no formal school; rather, individual scholars and patrons worked in the city over more than a century.

Key people

Alfonso VI (c. 1040-1109) was King of León from 1065 and of Castile from 1072. His reign saw the greatest Christian expansion in Iberia up to that time.

Yahya al-Qadir (died 1092) was the last Dhu’l-Nunid ruler of Toledo. He was killed in a revolt in Valencia.

Bernard of Sédirac (died 1125) was the first archbishop of Christian Toledo and a strong promoter of Roman church practices in Spain.

Why it matters

The capture of Toledo marked a turning point in the long series of wars later called the Reconquista. It moved the Christian frontier to the River Tagus, drew North African powers into Iberian politics, and opened a door through which Arabic and ancient Greek learning reached Latin Europe. The struggle it intensified continued for four more centuries, through the Battle of Las Navas de Tolosa to the fall of Granada in 1492.
