Abd al-Rahman III

Abd al-Rahman III ruled Muslim Spain, al-Andalus, for nearly half a century, from 912 to 961. He inherited a crumbling emirate whose writ barely ran beyond Córdoba, crushed the rebels who had divided it, and in 929 declared himself caliph, founding the Caliphate of Córdoba. Under him Córdoba became one of the richest and most cultivated cities in Europe, and the Christian kings of the north came to seek his favour.

Abd al-Rahman was born in Córdoba, most sources say on 18 December 890, though 889 and 891 are also given. He descended from the Umayyad dynasty that had once ruled the whole Islamic world from Damascus and, after its fall, had held al-Andalus as independent emirs for generations. His father, Muhammad, was killed by his own brother when Abd al-Rahman was a small child, and the boy grew up in the palace household. His mother was a Christian concubine, and his paternal grandmother was a Christian princess of Pamplona, which made him a nephew of Queen Toda of Navarre.

When his grandfather, Emir Abdallah, died in October 912, the throne passed over four surviving sons to the 21-year-old grandson, apparently as the old emir wished.

The new emir faced rebellion on every side. Muslim families of Iberian descent, the muwallads, held much of the south, the most formidable being Umar ibn Hafsun in his mountain fortress of Bobastro. Abd al-Rahman campaigned almost every year, taking Écija and Seville in 913 and a string of castles across Andalusia. Ibn Hafsun died in 917, but his sons held out until 928. Toledo, which had long defied Córdoba, surrendered in 932 after a two-year siege. To balance the rival Arab and Berber factions of his realm, he built up a corps of saqaliba, slaves of Eastern European origin, in his army and household.

On 16 January 929 Abd al-Rahman proclaimed himself caliph, rejecting any claim to authority over al-Andalus by the Abbasid caliphs in Baghdad and their new rivals, the Fatimids of North Africa. He based his claim on his Umayyad ancestry, and the title gave him religious as well as political leadership over the Muslims of al-Andalus. To counter the Fatimids he built a fleet based at Almería and backed Berber allies in Morocco, gaining Melilla, Ceuta and Tangier, although most of his influence in the Maghreb was lost after a Fatimid offensive in 958.

Abd al-Rahman fought the kingdoms of León and Navarre repeatedly. His army was destroyed at San Esteban de Gormaz in 917, but in 920 he won at Valdejunquera and sacked Pamplona. In 934 he forced his aunt Toda to accept him as overlord. In 939, however, Ramiro II of León and his allies crushed the caliph's army at Simancas, nearly killing him, and he never again led a campaign in person. Diplomacy, and quarrels among the Christian rulers, restored his position. In 958 the deposed king Sancho of León, King García of Pamplona and Queen Toda came to Córdoba to do him homage, and with his help Sancho regained his throne.

According to the chroniclers, a third of the caliph's revenue went on building. After taking the caliphal title he built Madinat al-Zahra, a vast palace city about seven kilometres from Córdoba, and he enlarged the Great Mosque. He also expanded the city's library. Later writers credited Córdoba with thousands of mosques, and it became a leading centre of learning in western Europe. Embassies arrived from the Byzantine Empire and from Otto I of Germany. Christians and Jews served at his court, among them the Jewish courtier Hasdai ibn Shaprut, who served as his financier.

Abd al-Rahman guarded his power closely and in 949 had one of his sons executed for plotting against him. He spent his last years at Madinat al-Zahra and died on 15 October 961, leaving the caliphate at its height to his son al-Hakam II.

Our 900 map shows the divided emirate he inherited, and the 1000 map shows the Caliphate of Córdoba in the generation after his death, when it still dominated the south and centre of what is now Spain.
