The Battle of Las Navas de Tolosa, known in Arab history as the Battle of Al-Uqab (معركة العقاب), took place on 16 July 1212 (15 Safar 609 AH) and was an important turning point in the Reconquista and in the medieval history of Spain.
The Christian forces of King Alfonso VIII of Castile were joined by the armies of his rivals, Sancho VII of Navarre, Peter II of Aragon and Afonso II of Portugal, in battle against the Berber Almohad Muslim rulers of the southern half of the Iberian Peninsula. The Caliph al-Nasir (Miramamolín 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.
The crushing defeat of the Christian Kingdoms and the death of Alfonso VIII King of Castile resulted in a sharp reduction of the Christian forces in the Iberian Peninsula. A few days later the Almohad army recaptured the fortress of Calatrava La Vieja ( Qal'at Rabah) and Malagón.
For the Kingdom of Castile, one of the main powers of the Iberian Peninsula, the death of Alfonso VIII meant a serious setback military, politically and dynastically. A regency was established and skirmishes with the Kingdom of León grew becoming a serious of war (The Castilian-Leonese Wars). The Crown of Aragón after the defeat turned back to consolidate its territories in Occitania and help Raimundo VI of Toulouse in the Albigensian Crusade.
