Battle of Las Navas de Tolosa
The turning point of their presence in the Iberian Peninsula came in 1212, when Muhammad III, "al-Nasir" (1199–1214) was defeated at the Battle of Las Navas de Tolosa in the Sierra Morena by an alliance of the Christian forces from Castile, Aragon and Navarre. Much of the remaining Moorish dominion in Iberia was lost in the ensuing decades, with the cities of Cordova and Seville falling to the Christians in 1236 and 1248 respectively.
