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 Dikāya 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. Dikāya 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 Dikāya 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 Dikāya was the son of Pulwa by a concubine, and that Dikāya begot Dŭka, who married Rantyan, a Malitigaw lady whose mother was Agŭb. The children of Dŭka and Rantyan were Bulus, Manalidtū, 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 Dŭka 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 Dŭka, and was principally derived from Bwayan.

The first ruler of Kabuntalan addressed as sultan was Digra Alam, the son of Umar Maya and Babak. Diagram No. 5 shows plainly that Digra Alam must have ruled about the same time as Sultan Pakīr Mawlāna Kanza of Mindanao, or his brother, Pakāru-d-Dīn, that is about the year A. D. 1770.

In a treaty between the Spanish Government and the sultan of Kabuntalan in the year 1857 the sultan is addressed as sultan of Tambao. He must be either Sultan Iskandar Sul-Karnayn or Sultan Idrīs, probably the latter.

About midway between Tambao and Libungan on the left bank of the river is a small monument, possibly a tomb, erected in memory of those who died during the fight between the Spaniards and Sultan Idrīs. In 1861 Tambao and Taviran or Tapidan were occupied by the Spaniards. In 1884 Sultan Idrīs submitted unconditionally to the Spanish authorities and received their protection against Datu Ūtū. Datu Ayūnan of Taviran, Datu Balabadan’s brother, aided the Spanish authorities in the war against Datu Ūtū and was one of the most prominent datus of Talakūkū and Magindanao.
