Having established the church, his next aim, after ascending the throne of Sulu, was the political reorganization of the government. This he undertook to frame on the same principles as those of an Arabian sultanate, giving himself all the power and prerogatives of a caliph. In enforcing such claims of absolute sovereignty, Abu Bakr declared to the people and their local chiefs that the widows, the orphans, and the land were his by right. This the people hesitated to submit to, and another measure was adopted which reconciled the interests of all parties. They agreed that all the shores of the island and all that territory within which the royal gong or drum could be heard should be the sultan’s personal property, and that the rest of the island should be divided among the subordinate chiefs and their people. The island was accordingly divided into five administrative districts, over each one of which one panglima exercised power subject to the supervision and superior authority of the sultan. These districts were again divided into smaller divisions, which were administered by subordinate officers or chiefs called maharaja, orangkaya, laksamana, parukka, etc. The districts were called Parang, Pansul, Lati, Gi’tŭng, and Lu’uk. The boundaries which it seemed necessary at that time to define were marked by large trees, none of which is living at present. Thus a sangay[13] tree separated Parang from Pansul. The location of this tree was at a point near Bud Agad and the stream Agahun, which runs down from Tumangtangis toward Maymbung. A bawnu[13] tree separated Pansul from Lati. This tree was located at a place called Indung, intermediate between Asturias and the walled town of Jolo. A mampalam[13] tree called Tarak separated Lati from Lu’uk. It was in the vicinity of the settlement of Sū’. A variety of durian tree named Siggal-saggal formed the boundary of Lati and Gi’tŭng.

According to later usage, these districts are defined as follows: Parang is the western district lying west of a line passing through a point east of the summit of Tumangtangis and a point on the southern coast 3 miles west of Maymbung. A line passing through Mount Pula and a point a little east of Maymbung marks the boundary between Pansul on the west and Lati and Gi’tŭng on the east. The watershed is generally considered as the dividing line between Lati and Gi’tŭng. A line joining Sū’ on the north and Lubuk on the south separates Lati and Gi’tŭng from Lu’uk. A sixth district has lately been carved out and termed Tandu, forming the easternmost part of the island. A line joining Sukuban on the south and Limawa on the north divides Tandu and Lu’uk.

The government thus organized was conducted in conformity with local customs and laws modified to such an extent as not to be repugnant and contrary to Mohammedan laws and the precepts of the Quran. To preserve this consistency, a code of laws was made and promulgated by Abu Bakr. This, once established, became the guide of all the subordinate officers of the state, who, as a rule, observed it and carried out its instructions. The general lines on which Abu Bakr conducted his government seem to have been followed very closely by all his successors. Such an adventurous and aggressive man as he was could not have stopped within the limits of the island. In all probability he pushed out in various directions, but no records have so far been found which give any account of the conquests he made or the limits of his empire. Abu Bakr lived thirty years in Sulu and died about 1480.

Successors of Abu Bakr

The dynasty founded by Abu Bakr ruled with a firmer hand and attained considerable power and fame. The new organization establishing law and order, consolidated the forces of the state and increased its influence on the outside world. Islam added a new element of strength and another stimulus to campaign and conquest. The Sulus never exceeded 60,000 in number, yet we learn that, prior to the arrival of Magellan, their power was felt all over Luzon and the Bisayan Islands, the Celebes Sea, Palawan, North Borneo, and the China Sea, and their trade extended from China and Japan, at the one extreme, to Malacca, Sumatra, and Java at the other.

Abu Bakr was succeeded by his second son, Kamalud-Din. Alawad-Din, the elder son, was weak-minded and was evidently not supported by the ministers of the state. The next three sultans who followed were Diraja, Upu, and Digunung. Their full names are, the Sultan Amirul Umara[14] Maharaja Diraja, the Sultan Muʿizzul Mutawadiʿin[15] Maharaja Upu, the Sultan Nasirud-Din Awal[16] Digunung[17] (or Habud[18]).

The sixth sultan was Mohammedul Halim[19] Pangiran Buddiman. During his reign Governor Sandé equipped and directed large expeditions to Borneo and Sulu. The armada sent to Sulu was commanded by Capt. Esteban Rodriguez de Figueroa and reached the town of Jolo in June, 1578. It is asserted that Rodriguez defeated Pangiran and exacted tribute from the Sulus. Rodriguez, however, did not occupy Jolo, and no permanent advantage was derived from his victory.
