Datu Djimbangan (Guimbangan) - known as Midted Sa Inged (Superintendent of the polity) of the Sultanate of Kudarangan, is the son of Sultan Bayao Bin Sultan Maitum, cousin of Datu Uto and elder brother and adviser to Datu Ali in the war against Pre-Spanish and the Pre-Americans Era. Datu Djimbangan lives at the old Spanish fort of Libungan, his only claim to distinction as he has but a small following. He is also known to Kabuntalan nobles as Datu Masbud (Fat) because he is very fat, hot tempered and inclined to be unreconstructed. He is also known as the thievish chieftain to the Spanish Governor of Cotabato for that once could come to Datu Djimbangan’s hand might well counted as lost.
Datu Djimbangan was suspected of being implicated in the murder of a soldier of the thirty-first infantry in December 1900 though it has never been proven against him. He depends for protection upon his brother Datu Ali, who is fond of him.
When the Spanish forces evacuated Cotabato in 1899, Datu Piang felt sure that the Spaniards would never be again in authority at Cotabato, he begged Governor Vilo, the latter governor of christian population, to let him have twenty rifles to defend himself against a rival. The christian governor agreed to this, and week by week Datto Piangʼs demands grew until, at length, all the rifles in the possession of the Christians passed to the Moros. But there still remained some cannons, and Datu Piang, having represented the necessity of making war on another chief up the Cotabato River, Vilo was persuaded to lend them to him. Suddenly Datu Piang, his son-in-law Datu Ali and his brother, Datu Djimbangan, at the head of a large party of armed Moros, fell upon and slaughtered the Christians. Viloʼs head was cut off. Datu Uto and his allies Datu Piang along with loyal moro datus marched into the town, killing and terrorizing Christian Filipinos.The Christians who were unable to escape were carried off as slaves into the interior. He and his companions made their selections for themselves, leaving the remainder for their followers.. As a cruel aftermath, Datu Djimbangan (or Guimbangan) "promptly caused the Filipina women of the place to be stripped and compelled to march before him on the public plaza in a state of nudity.
Ending of Slavery:
On December 1903, Moro Province announced the anti-slavery law. Wood and Taft thought that the Maguindanao would continue to follow the lead of colonial progress. Instead, the declaration of abolition destroyed the political and economic system of indirect rule over the whole valley through Datu Piang in Cotabato. Despite of Woods condemnation of Moros, he knew that the anti-slavery law will proved the flashpoint. It arouse a great deal of opposition among the Moro Datus especially Datu Ali and his brother Datu Djimbangan whos making a good deal of money in slave trading. The so called anti-slavery law ignited their general contempt for American Authority. General Leonard Wood also reported that all of the Datus except Datu Piang is united to resist the American rule for the operation of the slave law.
IIn March 1905, a sizeable band of Datu Ali’s men was at the Serenaya fort when U.S. troops attacked, killing many of the defenders and capturing Datu Djimbangan leader and brother of Datu Ali and held as hostage forcing Datu Ali to surrender. Datu Ali refuse to yield, encourage to continue the resistance by datus of Upper Cotabato (''Datu Ampatuan of Maganoy, Datu Mopuk of Dapitan, Datu Tambilawan of Libungan, Datu Manalintao of Madridagao, Datu Argao of Silag, and Datu Sansaluna''). The extant records of prosecutions for slavery in the Cotabato District are suggestive of the politically sensitive enforcement of the anti-slavery law. Notably.
Notably, Datu Djimbangan was captured after the fall of Datu Ali kota in March 1905 sentencing Datu Djimbangan to five years in prison, his co-defendants to 3 years term, and the purchaser of the slave to a 2 years sentence.
