Madja-as  The Confederation of Madya-as was a legendary pre-colonial supra-baranganic polity on the island of Panay in the Philippines. It was mentioned in Pedro Monteclaro's book titled Maragtas. It was supposedly created by Datu Sumakwel to exercise his authority over all the other datus of Panay. Like the Maragtas and the Code of Kalantiaw, the historical authenticity of the confederation is disputed, as no other documentation for Madya-as exists outside of Monteclaro's book. Madja-as was a pre-colonial chiefdom in Central Philippines. According to ancient tradition recorded by P. Francisco Colin, S.J., an early Spanish missionary in the Philippines, The inhabitants of Panay island in the Philippines were believed to be from North Sumatra; especially from the polity of Pannai, after which the Island of Panay (called "Ananipay" by the "Atis")was named after (i and y being interchangeable in Spanish). It was founded by Pannai loyalists who wanted to reestablish their state elsewhere following an occupation of their homeland. The polity of Pannai was a militant-nation settled by Warrior-Monastics as evidenced by the Temple ruins in the area as it was allied under the Sri-Vijaya Mandala that defended the conflict-ridden Strait of Malacca. The small kingdom traded-with and simultaneously repulsed any unlicensed Chinese, Indonesian, Indian or Arab navies that often warred in or pirated the strait of Malacca and, for a small country, they were adept at taking down armadas larger than itself - a difficult endeavour to achieve in the strait of Malacca, which was among the world's most hotly contested maritime choke-point where, today, one half of world trade passes through. The naval power of Pannai was successful in policing and defending the straights of Malacca for the Mandala of Srivijaya until the Chola invasion of Srivijaya occurred, wherein a surprise attack from behind, originating from the occupied capital, rendered the militant polity of Pannai vulnerable from an unprotected assault from the back flank. The Chola invaders eventually destroyed the polity of Pannai and its surviving soldiers, royals and scholars were said to have been secreted-out eastwards. In their 450 years of occupying Sumatra, they refused to be enslaved to Islam, Taoism or Hinduism after the polity's dissolution.
