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)
In 1646, a series of five naval actions known as the Battles of La Naval de Manila was fought between the forces of Spain and the Dutch Republic, as part of the Eighty Years' War. Although the Spanish forces consisted of just two Manila galleons and a galley with crews composed mainly of Filipino volunteers, against three separate Dutch squadrons, totaling eighteen ships, the Dutch squadrons were severely defeated in all fronts by the Spanish-Filipino forces, forcing the Dutch to abandon their plans for an invasion of the Philippines.
