Alfonso VIII (11 November 11555 October 1214), called the Noble ("El Noble") or the one of Las Navas ("el de las Navas"), was the King of Castile from 1158 to his death and King of Toledo. He is most remembered for his part in the Reconquista and the downfall of the Almohad Caliphate. After having suffered a great defeat with his own army at Alarcos against the Almohads in 1195, he led the coalition of Christian princes and foreign crusaders who broke the power of the Almohads in the Battle of Las Navas de Tolosa in 1212, an event which marked the arrival of a tide of Christian supremacy on the Iberian peninsula.
