Christians crush Almohads at Las Navas de Tolosa
A combined army under Alfonso VIII of Castile broke the Almohad caliphate's grip on Iberia in a mountain pass of the Sierra Morena. The victory opened Andalusia to the Reconquista and ended any serious Muslim attempt to reunify Spain under North African rule. Within a generation the great cities of Cordoba, Seville, and Valencia would fall to Christian armies pushing south.
Kamo no Chomei writes Hojoki
A Japanese courtier turned Buddhist hermit composed his Account of My Hut, a slender masterpiece of reclusive literature reflecting on fire, famine, earthquake, and the impermanence of all worldly things. Written in a ten-foot-square hut in the Kyoto hills, it became a touchstone of Japanese aesthetics. Its spare prose anticipated the wabi-sabi sensibility that would later define Japanese art and architecture.
Children's Crusade wanders Europe
Bands of peasant boys and girls, inspired by a shepherd's visions, set out from France and the Rhineland toward the Holy Land they believed the sea would part for. Most never reached the Mediterranean; others were sold to slavers in Marseille harbor. The episode haunted the medieval imagination and became a parable for innocence betrayed by a world too corrupt to protect it.
Thomas Becket's bones translated at Canterbury
Archbishop Stephen Langton presided over the solemn translation of Becket's relics to a new shrine in Canterbury Cathedral's Trinity Chapel. The ceremony, attended by thousands, cemented Canterbury as England's chief pilgrimage site until Henry VIII smashed the shrine. The gold and jewel-encrusted tomb drew pilgrims from across Europe, their offerings making the cathedral one of the wealthiest foundations in Christendom.
