The Battle of Sagrajas (October 23, 1086), (Arabic: معركة الزلاقة), was a battle between the Almoravid Yusuf ibn Tashfin and Castilian King Alfonso VI. The battleground was called az-Zallaqah (in English slippery ground) because the warriors were slipping all over the battle ground because of the tremendous amount of blood shed this day, and this gives rise to its name in Arabic.^{[citation needed]}

Background

Yusuf ibn Tashfin replied to the call of three Andalusian leaders (Abbad III al-Mu'tamid and others) and crossed to Andalusia with 7,000 warriors from Almoravids. He marched with his army to the north of al-Andalus until he reached az-Zallaqah. The army of Almoravids accumulated warriors from every place in al-Andalus and his army reached 30,000 warriors.

Alfonso VI of Castile reached the battleground with what turned out to be an inadequate force (according to contemporary Muslim sources, the real number wasn't higher than 14,000, ^{[citation needed]} other muslim sources estimated the number of 60,000). The two leaders exchanged messages before the battle. Yusuf ibn Tashfin offered three choices to the enemy: convert to Islam, to pay tribute (jizyah), or battle.

Alfonso VI was outnumbered but felt he could not safely withdraw. The battle started at Friday at dawn by attack from Castile. Yusuf Ibn Tashfin divided his army into 3 divisions. The first division was led by Abbad III al-Mu'tamid and consisted of 15,000 warriors, the second division consisted of 11,000 warriors lead by Yusuf ibn Tashfin and the third division consisted of 4,000 black African warriors with Indian swords and long javelins. Abbad III al-Mu'tamid and his division battled with Alfonso VI alone till the afternoon, then Yusuf ibn Tashfin and his division joined the battle and circled Alfonso VI and his troops. Alfonso's troops panicked and started to lose ground, then Yusuf ordered the third division of his army to attack and finish the battle.

The Castilian army included some 2,000 mounted knights but at least half the army was lost. Nevertheless, most of the noblemen survived, although several were killed, including counts Rodrigo Muñoz and Vela Oveguez. King Alfonso VI escaped the battlefield but sustained an injury to one leg that caused him to limp for the rest of his life.

Casualties were also heavy on the Almoravid side, specially for the hosts led by Dawud ibn Aysa, whose camp was even sacked in the first hours of battle, and by the governor of Badajoz, al-Mutawakkil ibn al-Aftas. The Sevilla governor al-Mu'tamid had been wounded in the first clash but his personal example of valour rallied the al-Andalus forces in the difficult moments of the initial Castilian charge led by Alvar Fañez. Those killed included a very popular imam from Cordoba, Abu-l-Abbas Ahmad ibn Rumayla.

Results

The battle was a decisive victory for the Almoravids but their losses meant that it was not possible to follow it up. Yusuf is said to have been disheartened by the carnage, in addition he had to return prematurely to Africa due to the death of his heir, Muslim sources claimed that Alfonso VI lost his leg in the battle. Castile suffered almost no loss of territory and was able to retain the psychologically important city of Toledo, only occupied the previous year. Instead the Christian advance was halted for several generations while both sides regrouped.
