Spanish–Moro conflict
The Spanish initiated the conflict by conquering the Philippines and invading Moro territory in an effort to subjugate the region to their rule since the 1500s. When the Spanish conquered the Muslim Kingdom of Maynila, a vassal of the Sultanate of Brunei, the Islamic rajah, Rajah Sulayman resisted the Spanish. Manila then became the capital of the Spanish Philippines after the conquest, with the Spanish forcibly converting people to Catholicism. The Spanish–Moro Wars started with the Castille War, a war between Spaniards and the Sultanate of Brunei. (The term "Moro" at this time included Muslim Tagalogs who were ruled by the Sultanate of Brunei).
History of the Philippines (1521–1898)
There was also an unsuccessful attack on Zamboanga in 1648. That year the Dutch promised the natives of Mindanao that they would return in 1649 with aid in support of a revolt against the Spanish. Several revolts did break out, the most serious being in the village of Lindáo. There most of the Spaniards were killed, and the survivors were forced to flee in a small river boat to Butuán. However, Dutch aid did not materialize or have objects to provide them.The authorities from Manila issued a general pardon, and many of the Filipinos in the mountains surrendered. However, some of those were hung or they were enslaved.
