On this day (16 July, 1212) Christian forces led by the Kingdom of Castile decisively defeated the Almohad (Muwahhidun) Empire at the Battle of Las Navas de Tolosa near Jaén in al-Andalus. The battle marked the beginning of the Almohad Empire's decline. In the following decades Cordoba, Seville, and Jaén would fall to the Christian conquest, with only Granada holding out for another 250 years.
