It appears that the first ruler of Kabuntalan was Dikaya, the son of a raja Bwayan, who simply held the honorary title of datu. His successor had no male heir, and one of his daughters, Babak, married Umar Maya Tubu-tubu of Magindanao, who became ruler of Kabuntalan and whose son was the first mentioned sultan there. This makes the line of descent of Kabuntalan related by Babak to the line of Bwayan and by Umar Maya to that of Magindanao. This relation to both Magindanao and Bwayan and the intermediate position Kabuntalan holds to both Saylud and Saraya have been very prominent factors in the history-making events of the valley, and have successively been taken advantage of by both Spanish and American authorities managing the affairs of the country. Diagram No. 5 gives in a very explicit and clear manner the names of the rulers of Kabuntalan or Bagumbayan, the order of their descent and succession, and the relation they hold to each other. Their names in the order of precedence are as follows: 1. Datu Dikaya 2. Datu Duka 3. Datu Umar Maya 4. Sultan Digra Alam 5. Sultan Mohammed Alimu-d-Din 6. Sultan sa-Barahaman 7. Sultan Mohammed Iskandar Manamir 8. Sultan Iskandar Sul-Karnayn 9. Sultan Idris 10. Sultan Abu Bakar The diagram shows also the principal relations of Bagumbayan to Bwayan and to Magindanao. Very little is known about the early history of Kabuntalan. Datu Kali Ibrahim, who is the chief judge of Bagumbayan, told the following story: Soon after the arrival of Dikaya in Kabuntalan the chief people of the village took their new datu in a boat on a little excursion. When they had gone some distance from the village they engaged in a sham fight and one party attacked the datu. This affair was prearranged and planned to test the courage and power of their datu. They made their attack with krises and bamboo lances. Dikaya was frightened and ran away. The people lost respect for him and expelled him from the village. Some time later he won their friendship by his good behavior and was reinstated as datu of Kabuntalan. The statement on page 47 that Dikaya was the son of Pulwa was taken from the Bwayan tarsila and is added on account of the relation it bears to the subject. The part of the tarsila of Bwayan which bears on this subject states that Dikaya was the son of Pulwa by a concubine, and that Dikaya begot Duka, who married Rantyan, a Malitigaw lady whose mother was Agub. The children of Duka and Rantyan were Bulus, Manalidtu, Puwi, and Miyandung. As Pulwa must have lived about the year 1550, and as Digra Alam must have ruled about the year 1770, the statement that Duka married Ambun and begot Babak, the mother of Digra Alam, can not be accepted as true. Some links in the list are evidently missing, but the fact is that the right to rule Kabuntalan belonged to the descendants of Duka, and was principally derived from Bwayan.
