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.
Spanish language in the Philippines
In Manila, the Spanish language had been more or less widespread, to the point where it has been estimated at around 50% of the population knew Spanish in the late 19th century. In his 1898 book "Yesterdays in the Philippines", covering a period beginning in 1893, the American Joseph Earle Stevens, an American who resided in Manila from 1893 to 1894, wrote:
Long contact between Spanish and the local languages, Chinese dialects, and later Japanese produced a series of pidgins, known as Bamboo Spanish, and the Spanish-based creole Chavacano. At one point these were the language of a substantial proportion of the Philippine population. Unsurprisingly, given that the Philippines was administrated for centuries from New Spain in present-day Mexico, Philippine Spanish is broadly similar to American Spanish, not only in vocabulary, but in pronunciation and grammar.
