The Battle of Las Navas de Tolosa took place on July 16, 1212, during the Reconquista, a period when Christian kingdoms sought to reclaim territory from Muslim rule in the Iberian Peninsula. This significant battle involved a coalition of Christian forces from the kingdoms of Castile, Aragon, and Navarre against the Almohad Caliphate, which controlled much of southern Spain. The Christian victory at Las Navas de Tolosa marked a turning point in the Reconquista, weakening Muslim power in the region. It opened the way for further Christian advances into Andalusia and contributed to the eventual fall of the last Muslim stronghold in Spain, Granada, in 1492.
