The town of Sulu (Joló) was formerly the residence of the Sultanʼs Court. This Sovereign had arrogantly refused to check the piratical cruisings made by his people against Spanish subjects in the locality and about the Islands of Calamianes; therefore, on February 11, 1851, General Antonio de Urbiztondo, Marquis de la Solana (an ex-Carlist chief), who had been appointed Gov.-General of the Philippines in the previous year, undertook to redress his nationʼs grievances by force. The Spanish flag was hoisted in several places. Sulu town, which was shelled by the gunboats, was captured and held by the invaders, and the Sultan Muhamed Pulalon fled to Maybun on the south coast, to which place the Court was permanently removed. At the close of this expedition another treaty was signed (1851), which provided for the annual payment of ₱1,500 to the Sultan and ₱600 each to three dattos, on condition that they would suppress piracy and promote mutual trade. Still the Mahometans paid the Spaniards an occasional visit and massacred the garrison, which was as often replaced by fresh levies.
In 1876 the incursions of the Mahometans and the temerity of the chiefs had again attained such proportions that European dominion over the Sulu Sultanate and Mindanao, even in the nominal form in which it existed, was sorely menaced. Consequent on this, an expedition, headed by Vice-Admiral Malcampo, arrived in the waters of the Sultanate, carrying troops, with the design of enforcing submission. The chief of the land forces appears to have had no topographical plan formed. The expedition turned out to be one of discovery. The troops were marched into the interior, without their officers knowing where they were going, and they even had to depend on Sulu guides. Naturally, they were often deceived, and led to precisely where the Mahometans were awaiting them in ambush, the result being that great havoc was made in the advance column by frequent surprises. Now and again would appear a few juramentados, or sworn Mahometans, who sought their way to Allah by the sacrifice of their own blood, but causing considerable destruction to the invading party. With a kris at the waist, a javelin in one hand, and a shield supported by the other, they would advance before the enemy, dart forward and backwards, make zigzag movements, and then, with a war-whoop, rush in three or four at a time upon a body of Christians twenty times their number, giving no quarter, expecting none—to die, or to conquer! The expedition was not a failure, but it gained little. The Spanish flag was hoisted in several places, including Sulu (Joló), where it remained from February 29, 1876, until the Spanish evacuation of the Islands in 1898.
The Mahometans (called by the Spaniards Moros) now extend over nine-tenths of Mindanao Island, and the whole of the Sultanate of Sulu, which comprises Sulu Island (34 miles long from E. to W., and 12 miles in the broadest part from N. to S.) and about 140 others, 80 to 90 of which are uninhabited.
The native population of the Sulu Sultanate alone would be about 100,000, including free people, slaves, and some 20,000 men-at-arms under orders of the Dattos.[6] The domains of His Highness reach westward as far as Borneo, where, up to 25 years ago, the Sultanate of Brunei[7] was actually tributary (and now nominally so) to that of Sulu. The Sultan of Sulu is also feudal lord of two vassal Sultanates in Mindanao Island. There is, moreover, a half-caste branch of these people in the southern half of Palauan Island (Parágua) of a very subdued and peaceful nature, compared with the Sulu, nominally under the Sulu Sultanʼs rule.
In Mindanao Island only a small coast district here and there was really under Spanish empire, although Spain (by virtue of an old treaty, which never was respected to the letter) claimed suzerainty over all the territory subject to the Sultan of Sulu. After the Sulu war of 1876 the Sultan admitted the claim more formally, and on March 11, 1877, a protocol was signed by England and Germany recognizing Spainʼs rights to the Tawi Tawi group and the chain of islands stretching from Sulu to Borneo. At the same time it was understood that Spain would give visible proof of annexation by establishing military posts, or occupying these islands in some way, but nothing was done until 1880, when Spain was stirred into action by a report that the Germans projected a settlement there. A convict corps at once took possession, military posts were established, and in 1882 the 6th Regiment of regular troops was quartered in the group at Bongao and Siassi.
Meanwhile, in 1880, a foreign colonizing company was formed in the Sultanate of Brunei, under the title of “British North Borneo Co.” (Royal Charter of November 7, 1881). The company recognized the suzerain rights of the Sultan of Sulu, and agreed to pay to him an annual sum as feudal lord. Spain protested that the territory was hers, but could show nothing to confirm the possession. There was no flag, or a detachment of troops, or anything whatsoever to indicate that the coast was under European protection or dominion. Notes were exchanged between the Cabinets of Madrid and London, and Spain relinquished for ever her claim to the Borneo fief of Brunei.
The experience of the unfortunate Sultan Alimudin (Ferdinand I.) taught the Sulu people such a sad lesson that subsequent sultans have not cared to risk their persons in the hands of the Spaniards. There was, moreover, a Nationalist Party which repudiated dependence on Spain, and hoped to be able eventually to drive out the Spaniards. Therefore, in 1885, when the heir to the throne, Mohammad Jamalul Kiram (who was then about 15 years old) was cited to Manila to receive his investiture at the hands of the Gov.-General, he refused to comply, and the Government at once offered the Sultanate to his uncle, Datto Harun Narrasid, who accepted it, and presented himself to the Gov.-General in the capital.
The ceremony of investiture took place in the Government House at Malacañan near Manila on September 24, 1886, when Datto Harun took the oath of allegiance to the King of Spain as his sovereign lord, and received from the Gov.-General, Emilio Terrero, the title of His Excellency Paduca Majasari Maulana Amiril Mauminin Sultan Muhamad Harun Narrasid, with the rank of a Spanish lieut.-general. The Gov.-General was attended by his Secretary, the Official Interpreter, and several high officers. In the suite of the Sultan-elect were his Secretary, Tuan Hadji Omar, a priest, Pandita Tuan Sik Mustafá, and several dattos. For the occasion, the Sultan-elect was dressed in European costume, and wore a Turkish fez with a heavy tassel of black silk. His Secretary and Chaplain appeared in long black tunics, white trousers, light shoes, and turbans. Two of the remainder of his suite adopted the European fashion, but the others wore rich typical Moorish vestments.
The Sultan returned to his country, and in the course of three months the Nationalist Party chiefs openly took up arms against the King of Spainʼs nominee, the movement spreading to the adjacent islands of Siassi and Bongao, which form part of the Sultanate.[8]
