The early Bangsamoro were under the leadership of Datu Akob, an Iranun datu whose daughter caught the fancy of Datu Macaumbang (Sultan of Taga Nonok), also an Iranun from Malabang, Tukuran, also part of modern Pagadian. He was the son of Shariff Apo Tubo who descended from the bloodline of Shariff Kabungsuan, the first Sultan of the Maguindanao Sultanate. With the approval of Sultan Datu Akob, Datu Macaumbang married Bai Putri Panyawan Akob, the beautiful daughter of the royal datu of Pagadian City and royal bai putri of Raya.
