A 13th century (c.1200 A.D.) event explains the origins of the festival. A group of 10 Malay chieftains called Datus, fleeing from the island of Borneo settled in the Philippines, and were granted settlement by the Ati people, the tribes of Panay Island. Datu Puti, Makatunaw’s chief minister made a trade with the natives and bought the plains for a golden salakot, brass basins and bales of cloth. For the wife of the Ati chieftain, they gave a very long necklace. Feasting and festivities followed soon after. The Ati-Atihan was originally a pagan festival from this tribe practicing Animism, and their worshiping their anito god. Spanish missionaries gradually added a Christian meaning. Today, the Ati-Atihan is celebrated as a religious festival.
