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).
Spanish Filipino
Between 1565 and 1898, Hispanics from Latin America and Spain sailed to and from the Philippine Islands. This contributed to the assimilation of the Hispanics into everyday society. According to an 1818 study by the renowned German ethnologist Fëdor Jagor entitled "The Former Philippines thru Foreign Eyes", not less than 1/3rd of the inhabitants of the island of Luzon were then mixed with varying degrees of Spanish ancestry and the vast majority of military personnel then had Latin-American origins.
