What happened
By 1212 the Almohad Caliphate, which had replaced the Almoravids as the dominant Muslim power in Iberia, faced a rare united front: the rival kings Alfonso VIII of Castile, Sancho VII of Navarre, and Peter II of Aragon combined their armies against the Almohad caliph al-Nasir. On July 16, 1212, the Christian coalition caught the Almohad camp by surprise near Las Navas de Tolosa. Alfonso VIII's own letter describing the battle credited the outcome to divine favor, and a contemporary Arabic chronicler blamed the defeat on divisions within the Almohad ranks, writing that Almohad forces fled at the first Christian assault. A Latin chronicle of the period described the scale of the rout in stark terms, and after the battle Alfonso VIII returned in triumph to Toledo.
Why it matters
Las Navas de Tolosa broke Almohad military power in Iberia permanently; within fifty years, most remaining Muslim territory on the peninsula had fallen to Christian forces, leaving only the emirate of Granada standing by the mid-13th century.
How we know
The battle is documented in multiple independent contemporary sources, including Alfonso VIII's own campaign letter, a Latin chronicle, and the Arabic chronicler al-Marrakushi's account, all of which agree on the coalition's composition and the scale of the Almohad defeat.
