Battle of Alarcos - Aftermath

Aftermath

The outcome of the battle shook the stability of the Kingdom of Castile for several years. All nearby castles surrendered or were abandoned: Malagón, Benavente, Calatrava, Caracuel and Torre de Guadalferza, and the way to Toledo was wide open. Fortunately for the Christians, however, Abu Yusuf Ya'qub al-Mansur moved back to Sevilla to make good his own considerable losses; there he took the title of al-Mansur Billah ('Made victorious by God').

For the next two years, al-Mansur's forces devastated Extremadura, the Tagus valley, La Mancha and even the area around Toledo; they moved in turn against Montánchez, Trujillo, Plasencia, Talavera, Escalona and Maqueda. Some of these expeditions were led by the renegade Pedro Fernández de Castro. Most significantly, however, these raids did not lead to any territorial gains for the caliph, although Almohad diplomacy did obtain an alliance with King Alfonso IX of León (who had been enraged when the Castilian king had not waited for him before the battle of Alarcos) and the neutrality of Navarre. These alliances proved to be temporary only.

But the caliph was losing interest in the affairs of the Iberian Peninsula; he was in poor health, his objective of retaining a hold over al-Andalus appeared to be a complete success, and in 1198 he returned to Africa. He died in February 1199.

However, the success of the battle proved to be short-lived. When the Almohad caliph Muhammad an-Nasir attempted to build on it 16 years later with a new Iberian offensive, he was crushingly defeated in the more decisive Battle of Las Navas de Tolosa. This battle was to mark a turning-point that led to the end of Moorish rule in the Iberian Peninsula. The Almohad Empire itself collapsed a few years later.
