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 (1898–1946)
The history of the Philippines from 1898 to 1946 began with the outbreak of the Spanish–American War in April 1898, when the Philippines was still part of the Spanish East Indies, and concluded when the United States formally recognised the independence of the Republic of the Philippines on July 4, 1946.
