Battle of Las Navas de Tolosa

In 1195, the Almohads defeated Alfonso VIII of Castile in the Battle of Alarcos. After this victory, they took several important cities: Trujillo, Plasencia, Talavera, Cuenca, and Uclés. Then, in 1211, Muhammad al-Nasir crossed the Strait of Gibraltar with a powerful army, invaded Christian territory, and captured Salvatierra Castle, the stronghold of the knights of the Order of Calatrava. The threat to the Hispanic Christian kingdoms, was so great that Pope Innocent III called Christian knights to a crusade.

There were some disagreements among the members of the Christian coalition; notably, French and other European knights did not agree with Alfonso's merciful treatment of Jews and Muslims who had been defeated in the conquest of Malagón and Calatrava la Vieja. Previously, they had caused problems in Toledo (where the different armies of the Crusade gathered), with assaults and murders in the Jewish Quarter.

Alfonso crossed the mountain range that defended the Almohad camp, sneaking through the Despeñaperros Pass, led by Martín Alhaja, a local shepherd who knew the area. The Christian coalition caught the encamped Moorish army by surprise, and Alhaja was granted the hereditary title Cabeza de Vaca for his assistance to Alfonso VIII.

The battle was fought at relatively close range, so that neither the Almohads nor the Spaniards could use archers in the melee-dominated fight. Spanish knights became locked in close-quarter combat, in which they were superior to the Almohads.

"They attacked, fighting against one another, hand-to-hand, with lances, swords, and battle-axes; there was no room for archers. The Christians pressed on." – (The Latin Chronicle of The Kings of Castile)

Some of the Spanish knights, namely the Order of Santiago, eventually broke the Almohad line of defense decisively as they inflicted heavy casualties on the Almohads and established a breakthrough with gaps appearing in the enemy lines. This led to a possible spearhead. King Sancho VII then led his mounted knights through the gaps, exploiting them, and charged at the Caliph's tent.[11]

According to legend, the Caliph had surrounded his tent with a bodyguard of slave-warriors. Though it was once claimed that these men were chained together to prevent flight, it is considered more likely that this results from a mistranslation of the word "serried", meaning a densely packed formation. The Navarrese force led by their king Sancho VII broke through this bodyguard. The Caliph escaped, but the Moors were routed, leaving heavy casualties on the battlefield.[12] The victorious Christians seized several prizes of war; Muhammad al-Nasir's tent and standard were delivered to Pope Innocent III.[13]

Christian losses were far fewer, only about 2,000 men (though not so few as legend had it).[6] The losses were particularly notable among the Orders: those killed included Pedro Gómez de Acevedo (bannerman of the Order of Calatrava), Alvaro Fernández de Valladares (comendator of the Order of Santiago), Pedro Arias (master of the Order of Santiago, died of wounds on 3 August), and Gomes Ramires (Portuguese master of the Knights Templar and simultaneously master of Leon, Castile, and Portugal); Ruy Díaz (master of the Order of Calatrava) was so grievously wounded that he had to resign his command.

Muhammad al-Nasir died in Marrakech shortly afterwards.

The crushing defeat of the Almohads significantly hastened their decline both in the Iberian Peninsula and in the Maghreb a decade later. That gave further impulse to the Christian Reconquest and sharply reduced the already declining power of the Moors in Iberia. Shortly after the battle, the Castilians took Baeza and then Úbeda, major fortified cities near the battlefield and gateways to invade Andalusia. According to a letter from Alfonso VIII of Castile to Pope Innocent III, Baeza was evacuated and its people moved to Úbeda; Alfonso laid siege, killing 60,000 Muslims and enslaving many more. According to the Latin Chronicle of Kings of Castile the number given is almost 100,000 Saracens, including children and women, who were captured.[14]

Thereafter, Alfonso VIII's grandson Ferdinand III of Castile took Córdoba in 1236, Jaén in 1246, and Seville in 1248; then he took Arcos, Medina-Sidonia, Jerez, and Cádiz. In 1252, Ferdinand was preparing his fleet and army for invasion of the Almohad lands in Africa, but he died in Seville on 30 May 1252, during an outbreak of plague in southern Hispania; only his death prevented the Castilians from taking the war to the Almohad on the Mediterranean coast. James I of Aragon conquered the Balearic Islands (from 1228 over the following four years) and Valencia (the city capitulated on 28 September 1238).

By 1252 the Almohad empire was almost finished, at the mercy of another emerging Berber power. In 1269 a new association of Berber tribes, the Marinids, took control of Morocco. Later, the Marinids tried to recover the former Almohad territories in Iberia, but they were definitively defeated by Alfonso XI of Castile and Afonso IV of Portugal in the Battle of Río Salado, the last major military encounter between large Christian and Muslim armies in Hispania. So, the battle of Las Navas de Tolosa seems to have been a true turning point in the history of the region, including the western Mediterranean sea.
