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.
Federal State of the Visayas
The Spanish–American War which sparked in Cuba reached the Philippines. On May 1, 1898, US Commodore George Dewey defeated the Spanish Navy in Manila. The Spanish designated Iloilo City as the colonial government's capital after Manila fell to the Americans on August 13, 1898, and later installed Roque Lopez as president of the provisional government in Santa Barbara town in Iloilo. Diego de los Ríos was named Governor General over the Philippines. The Spanish armed the Iloilo Voluntarios, a battalion composed mainly of Ilonggos believing that they are loyal to the Spanish crown. However, Ilonggo revolutionaries, calling themselves the "Ejercito Libertador", started a revolt gaining control of all of Panay within days, except for Iloilo City, Jaro, La Paz and Molo.
