Battle of Sagrajas (1086): Almoravids Defeat Alfonso VI

The Battle of Sagrajas, known in Arabic as al-Zallaqa, was fought on 23 October 1086 near Badajoz in western Spain. An army of North African Almoravids under Yusuf ibn Tashfin, joined by the forces of several Muslim kingdoms of al-Andalus, defeated King Alfonso VI of León and Castile. The victory halted the Christian advance that had followed the fall of Toledo and opened the way for the Almoravids to take over Muslim Spain.

Background: Toledo and the taifas

After the Caliphate of Córdoba collapsed in the early eleventh century, al-Andalus split into rival states called taifas. They were wealthy but weak, and many paid regular tribute, known as parias, to Christian rulers for protection. Alfonso VI collected tribute from several of them and steadily increased his demands.

In May 1085 Alfonso took Toledo, the old Visigothic capital and one of the greatest cities of al-Andalus. The rulers of Seville, Badajoz and Granada feared they would be next. Led by al-Mu’tamid of Seville, they turned to Yusuf ibn Tashfin, leader of the Almoravids, whose Berber empire now controlled Morocco.

Inviting a powerful outside army was a risk, and the taifa kings knew it. A famous saying attributed to al-Mu’tamid by later Arabic writers expresses his choice: he would rather tend camels in Africa than pigs in Castile. Whether or not he said it in those words, it captures the dilemma.

The campaign

Al-Mu’tamid handed over the port of Algeciras, and Yusuf’s army crossed the Strait of Gibraltar in the summer of 1086. It marched via Seville towards Badajoz, gathering contingents from Seville, Granada, Málaga and Badajoz on the way.

Alfonso was besieging Zaragoza when he heard of the landing. He broke off the siege, called in troops from Castile, León and his allies, and moved south-west to meet the threat. The two armies met on the plain north-east of Badajoz.

According to the Arabic accounts, letters were exchanged before the battle, and the date of the fighting was itself the subject of manoeuvring. The battle took place on Friday 23 October 1086.

What happened

Alfonso’s heavy cavalry charged first and drove back the Andalusi vanguard, which included al-Mu’tamid’s Sevillan troops. The taifa forces suffered heavy losses, but al-Mu’tamid held his ground long enough for the Almoravid reserve to act.

Yusuf then sent part of his army round to attack the Castilian camp and rear. Disciplined Almoravid infantry, with drums that reportedly unsettled the Christian horses, and a reserve of Yusuf’s personal guard turned the battle. The Castilian army broke, and by nightfall Alfonso, wounded in the leg, was retreating with a few hundred horsemen towards Coria.

The numbers involved are unknown. Chroniclers on both sides gave inflated figures in the tens of thousands, and modern historians believe each army was probably several thousand strong. Christian losses were clearly heavy.

Key people

• Yusuf ibn Tashfin (died 1106), Almoravid ruler and the architect of the victory.
• Alfonso VI (ruled 1065–1109 in León), king of León and Castile, conqueror of Toledo.
• Al-Mu’tamid ibn Abbad, king and poet of Seville, who led the call for Almoravid help.
• Al-Mutawakkil ibn al-Aftas, ruler of Badajoz, on whose territory the battle was fought.

Consequences

Yusuf did not follow up the victory. News of the death of his son in Ceuta led him to return to Africa within weeks, leaving only part of his army in Spain. Toledo was not attacked, and Alfonso soon recovered. Valencia, too, remained outside Almoravid control until after the death of El Cid.

The battle’s main effect was on al-Andalus itself. Yusuf came back in 1088 to besiege the Castilian fortress of Aledo and saw the taifa kings quarrelling among themselves. With the support of Maliki religious scholars, he returned in 1090 to depose them: Granada fell that year, Seville in 1091 and Badajoz in 1094. Muslim Spain became a province of the Almoravid empire.

Legacy

In Muslim tradition al-Zallaqa became one of the celebrated victories of al-Andalus, remembered alongside the earlier triumphs of the Umayyad era. Andalusi and North African writers presented Yusuf ibn Tashfin as a pious defender of Islam who had rescued the peninsula from its own quarrelling princes.

Christian chroniclers, by contrast, treated the defeat briefly. For Castile it was a setback rather than a disaster: Alfonso VI kept Toledo and ruled for more than twenty years longer. Yet the battle showed that the Almoravids, with their disciplined infantry and unified command, were a far stronger opponent than the taifa kings had been, and the frontier in central Spain remained contested for over a century, until the Christian victory at Las Navas de Tolosa in 1212.

Timeline

• 1086, 23 October: Battle of Sagrajas; Alfonso is defeated and wounded.

• 1090–1094: Yusuf deposes the kings of Granada, Seville and Badajoz.

Why it matters

Sagrajas stopped the rapid Christian advance that followed Toledo and showed that the frontier in Iberia could still move both ways. It also ended the age of the independent taifa kings, bringing al-Andalus under North African rule for the next century and more.
