Datu Puti is the supposed leader of the ten Bornean datus who sailed to Panay to escape from the tyrannical rule of Datu Makatunaw. Under his command, they reached Siwaragan (now San Joaquin), Iloilo. Since he was the most powerful of the ten, it was agreed that he would return to Borneo immediately to challenge the Makatunaw, leaving Datu Sumakwel as the new leader of the group. Legend says that from the day of Puti's departure, nothing was ever heard of him again.
