Datu Kalantiaw (Rajah Bendahara Kalantiaw) (sometimes spelled Kalantiao) was once considered an important part of Philippine history as the one who created the first legal code in the Philippines, known as the Code of Kalantiaw in 1433. He was considered by Filipinos, particularly the Visayans, as the third head of Panay (an island in Visayas with four provinces: Aklan, Antique, Capiz and Iloilo). He was a source of fierce Filipino and Visayan pride for decades, until his authenticity was debunked by Historian William Henry Scott in his PhD thesis, Critical Study of the Prehispanic Source Materials for the Study of Philippine History relegating the once legendary historical figure into a mythical Filipino character or an urban legend.
