Every settlement of these former pagan tribes had its chief. The chief was called timway. Tabunaway was the last timway of Magindanao. Manumbali was the last timway of Slangan. The Tirurays and the Manobos still call their chief timway. The ruler of the Mohammedan dynasty assumed the title of datu. The noun datu means king or ruler; the verb datu means to rule. Kabungsuwan retained the title sharif. His son Maka-alang also is always referred to as sharif. Later the term datu prevailed, and the first datu who is mentioned in the tarsila as sultan was Sultan Qudrat, whom Combés called Corralat. Soon after Kabungsuwan had established his power in Magindanao he received the submission of many chiefs, all of whom he converted to Islam. Later he advanced up the valley to Bwayan and along the coast to Malabang. Some believe that he went to the Ranao country, but it is difficult to support all the statements made. His descendants and his converts carried on the war and the conversion, so that before the Spaniards reached their country their conquest and conversion had reached the present limits. The story of Putri Tunina and her marriage to Kabungsuwan is universally known to the Moros of Mindanao. The custom of burying the dead next to the house, as practiced by Tabunaway, is still common everywhere, and trees are often planted around the tomb. By Sarabanun, the sister of Tabunaway, Kabungsuwan begot no children. By Putri Tunina he begot three daughters, one of whom, Putri Mamur, married the first Moslem datu of Bwayan, Malang-sa-Ingud. At Malabang Kabungsuwan married Angintabu, the daughter of the chief of that place, and begot Sharif Maka-alang, who succeeded him. The people of Magindanao who aided Kabungsuwan in his wars secured from him certain privileges and favors over their neighbors. These privileges are still claimed by the dumatus, the present descendants of Tabunaway. They have not paid tribute to the datus and have often intermarried with the datu class. It was different with the people of Slangan. The descendants of Manumbali and his subjects all became subjects and servants to the datus. Their descendants are, however, still known and live in Lugaylugay, about 1 mile below Cotabato, and on the same side of the Pulangi. Little is known about Sharif Maka-alang. He in all probability ruled in Magindanao, not in Malabang. His wife was a Bilan woman related to Parasab, a Bilan chief.
