The Code of Kalantiaw was a fictitious legal code said to be written in 1433 by Datu Kalantiaw, a chief on the island of Negros in the Philippines. It was created in 1913 by Jose E. Marco as a part of his historical forgery entitled Las antiguas leyendes de la Isla de Negros (The Ancient Legends of the Island of Negros), which he attributed to a priest named Jose Maria Pavon. In 1917, the historian Josue Soncuya wrote about the Code of Kalantiaw in his book Historia Prehispana de Filipinas (Prehispanic History of the Philippines) where he switched the location of the Code’s origin from Negros to his home province of Aklan on the island of Panay because he found two Aklanon words in the text. Other authors throughout the 20th century, and up to the present day, further embellished the Kalantiaw story, but in 1968 the historian William Henry Scott debunked the hoax in his book Prehispanic Source Materials for the Study of Philippine History. The Code of Kalantiaw is no longer a part of the standard history texts in the Philippines but the story is still believed by some people, especially in the central provinces.
