The
July 16 1212 ' battle of Las Navas de Tolosa' (
Spanish:'Batalla de Las Navas de Tolosa' /
Arabic:'معركة العقاب') is considered a major turning point in the history of
Medieval Iberia. The forces of King
Alfonso VIII of Castile were joined by the armies of his
Christian rivals,
Sancho VII of Navarre,
Afonso II of Portugal and
Peter II of Aragon in battle against the
Berber Muslim Almohad rulers of the southern half of the
Iberian Peninsula. The sultan
Caliph al-Nasir (''
MiramamolÃn'' in the Spanish chronicles) led the
Almohad army, made up of people from the whole Almohad empire. Most of the men in the Almohad army came from the African side of the empire, which included
Tunisia,
Algeria,
Senegal,
Morocco,
Mauritania and the southern part of the Iberian peninsula right below Las Navas de Tolosa line.
In 1195, Alfonso VIII of Castile had been defeated by the Almohads in the so-called
Disaster of Alarcos. After this victory the Almohads had taken important cities as
Trujillo,
Plasencia,
Talavera,
Cuenca and
Uclés. Then, in 1211,
Muhammad al-Nasir had crossed the
Strait of Gibraltar with a powerful war machine, and invaded the Christian territory and captured the stronghold of the
Calatrava Knights in
Salvatierra. After this, the threat was so great for the Iberian Christian kingdoms that the Pope
Innocent III called European knights to a
crusade. After some disagreements among the members of the Christian coalition, Alfonso managed to cross the mountain range that defended the Almohad camp, sneaking through the
Despeñaperros Pass, so that the Christian coalition caught by surprise and smashed the Moorish army that left some 100,000 casualties at the battleground. The battle was a bloody and decisive encounter.
The Caliph Muhammad al-Nasir himself died shortly after the battle in
Marrakesh, where he had fled after the defeat. The culmination of the battle took place when Sancho VII of Navarre himself broke into the Caliph's fortified camp, broke up the defensive ring and disbanded al-Nasir's personal bodyguard; nonetheless Muhammad al-Nasir managed to escape. After that, the Christian army engaged in the annihilation of the Muslim troops, so that very few of them could escape the killing.
Despite legends that Christian casualties were very few, in fact they were some 2,000 men, and particularly heavy among the Orders. Those killed included Pedro Gomez de Acevedo (bannerman of the Orden de Calatrava), Alfonso Fernandez de Valladares (comendator of the Orden de Santiago), Pedro Arias (master of the Orden de Santiago, died of wounds on 3 August) and Gomez Ramirez (master of the Orden del Temple). Ruy Diaz (master of the Orden de Calatrava) was so grievously wounded that he had to resign his command.

The new blazon of Navarre.
According to legend, the emir had his tent surrounded with chained slaves as a defence.
The Navarrese however cut the chains and broke into the tent.
As a memorial, the kingdom of Navarre changed
its coat of arms with one depicting a golden chain on a gules field with an emerald.
Aftermath
The crushing defeat of the Almohads significantly hastened their decline both in the Iberian Peninsula and in the
Maghreb a decade later, this would give further momentum to the
Christian Reconquest begun by the kingdoms of northern Iberia centuries before, resulting in a sharp reduction in the already declining power of the
Moors in the Iberian Peninsula. Shortly after the battle, the Castilians retook
Baeza and then
Úbeda, major fortified cities near the battlefield, and gateways to invade
Andalucia. Thereafter,
Ferdinand III of Castile retook
Córdoba in 1236,
Jaén in 1246, and
Seville in 1248; then he took
Arcos,
Medina-Sidonia,
Jerez and
Cádiz. After this chain of victories, only Ferdinand's death prevented the Castilians from crossing the Gibraltar Strait to take the war to the heartland of the Almohad empire. Ferdinand III died in Seville on
May 30, 1252, when a plague spread over the southern part of the Iberian peninsula while he was preparing his army and fleet to cross the Gibraltar Strait. On the Mediterranean coast,
James I, Count of Barcelona and King of Aragon, proceeded to conquer the
Balearic Islands (from 1228 over the following four years) and
Valencia (the city capitulated
September 28).
By the year 1252, the Almohad empire was almost over, at the mercy of another emerging African power. In 1269, a new association of African tribes, the
Marinid, had taken control of the Maghreb, and most of the former Almohad empire was under their rule. Later, the Merinid tried to recover the former Almohad territories in the Iberian peninsula, but they were definitively defeated by
Sancho IV, Ferdinand's grandson, in the
Battle of Salado, the last major military encounter between large Christian and Muslim armies in the Iberian peninsula.
In 1294 Sancho IV retook
Tarifa, key to the control of the Gibraltar Strait; and
Granada,
AlmerÃa and
Málaga were the only major cities of the time in the Iberian peninsula still in Muslim hands. These three cities were the core of the
Nazhari Kingdom of Granada, which was a
vassal state of
Castile, until the kingdom was finally taken by the
Catholic Kings in 1492. 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.
