Battle of Las Navas de Tolosa
The Almohad dominance of Iberia continued until 1212, when Muhammad al-Nasir (1199–1214) was defeated at the Battle of Las Navas de Tolosa in the Sierra Morena by an alliance of the Christian princes of Castile, Aragon, Navarre and Portugal. Nearly all of the Moorish dominions in Iberia were lost soon after, with the great Moorish cities of Córdoba and Seville falling to the Christians in 1236 and 1248, respectively.
