Persecution of Muslims
The Philippines is predominantly a Christian society with a complicated history of relations between Islam and Christianity. Despite historic evidence of Islamization spreading throughout the islands in the 13th–16th centuries, the archipelago came under Spanish rule in the 16th century. The Spanish proselytized many natives, and labelled those who remained Muslims as "Moro", a derogatory term recalling the Moors, an Islamic people of North Africa who occupied parts of Spain for several centuries. Today, this term "Moro" is used to refer to the indigenous Muslim tribes and ethnic groups of the country. When the Spanish came to the Philippine islands, most of the natives in Luzon and Visayas were pagans with Muslim minorities, and while Spanish proselytized many natives, many Muslims in Luzon and Visayas were not exempted by the Spaniards from the Spanish Inquisition, wherein Muslims to become Catholics or die for their faith. Those who remained Muslims are only the natives of Mindanao and Sulu which the Spaniards did not invade or had control of only briefly and partially.
History of the Philippines
Around 1563 AD, at the closing stages of the precolonial era, the Kedatuan of Dapitan in Bohol achieved prominence and it was known to a later Spanish missionary, Alcina, as the "Venice of the Visayas", because it was a wealthy, wooden and floating city-state in the Visayas. However, this kedatuan was eventually attacked and destroyed by soldiers from the Sultanate of Ternate, a state made up of Muslim Papuan people. The survivors of the destruction, led by their datu, Pagbuaya, migrated to northern Mindanao and established a new Dapitan there. They then waged war against the Sultanate of Lanao and settled in the lands conquered from them. Eventually, in vengeance against the Muslims and Portuguese allied to the Ternateans, they aided the Spanish in the conquest of Muslim Manila and in the Spanish expeditions to capture Portuguese Ternate. There was also a simmering territorial conflict between the Polity of Tondo and the Bruneian vassal-state, the Islamic Rajahnate of Maynila, to which the ruler of Maynila, Rajah Matanda, sought military assistance against Tondo from his relatives at the Sultanate of Brunei. The Hindu Rajahnates of Butuan and Cebu also endured slave raids from, and waged wars against the Sultanate of Maguindanao. Simultaneous with these slave-raids, was the rebellion of Datu Lapu-Lapu of Mactan against Rajah Humabon of Cebu. The sparse population and the multiple states competing over the limited territory and people of the islands simplified Spanish colonization by allowing its conquistadors to effectively employ a strategy of divide and conquer for rapid conquest.
