The Confederation of Madja-as
During the 11th century several exiled datus of the collapsing empire of Srivijaya led by Datu Puti led a mass migration to the central islands of the Philippines, fleeing from Rajah Makatunao of the island of Borneo. Upon reaching the island of Panay and purchasing the island from Negrito chieftain Marikudo, they established a confederation of polities and named it the Confederation of Madja-as centered in Aklan and they settled the surrounding islands of the Visayas. This confederation reached its peak under Datu Padojinog. During his reign the confederations' hegemony extended over most of the islands of Visayas. Its people consistently made piratical attacks against Chinese imperial shipping.
