1569 disestablishments

Madja-as was a legendary precolonial confederacy 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.
