of the country until immediately after the People Power Revolution in February 1986 and the subsequent ratification of the 1987 Constitution. The new charter dropped Spanish as an official language and today it is very rare to find a native Spanish speaker, less than 0.1% of the population. However, the government of Gloria Macapagal Arroyo, the fourteenth president of the Philippines and a hispanophone, reintroduced the study of Spanish into the state school system. Name of the Philippines The name of the Philippines comes from the king of Spain Philip II. It was given by the Spanish explorer Ruy López de Villalobos who named the islands of Samar and Leyte "Las Islas Felipinas" (The Philippine Islands), during his expedition in 1543. Throughout the colonial period, the name Felipinas (Philippines) was used, and became the official name of the Philippines. There are many provinces in the Philippines with Spanish names, such as Nueva Vizcaya, Nueva Écija (Nueva Ecija), Laguna, Isabela, Quirino, Aurora, La Unión (La Union), Marinduque, Antique, Negros Occidental, Negros Oriental, Nueva Segovia and Valle de Compostela. Many cities and towns are also named in Spanish, such as Medellin, La Libertad, Naga, Camarines Sur (prior to 1919 was known as Nueva Cáceres), Las Piñas, Prosperidad, Isabela, Sierra Bullones, Angeles, La Paz, Esperanza, Buenavista, Pilar, La Trinidad, Garcia Hernandez, Trece Martires, Los Baños, and many more. There are numerous other towns and cities named after saints, such as San Fernando, Santa Rosa, San Isidro, San José, San Juan and San Pablo, as well as after Spanish places like Madrid, Santander, Toledo, Cádiz, Valencia, Murcia, Lucena, and Pamplona. Other native Filipino names are spelled using Spanish orthography, such as Cagayán de Oro, Parañaque, and Cebú. Filipino Spanish surnames A Spanish or Latin-sounding surname does not necessarily denote Spanish ancestry in the Philippines. The names derive from the Spanish conquest of the Philippine Islands and its implementation of a Spanish naming system. After the Spanish conquest of the Philippine islands, many early Christianized Filipinos assumed religious-instrument or saint names. This resulted in many people surnamed "de Los Santos" ("of the Saints"), "de la Cruz" ("of the Cross"), "del Rosario" ("of the Rosary"), "Bautista" ("Baptist"), and "de Jesus" ("of Jesus"). On November 21, 1849, the Spanish Governor-General of the Philippine Islands, Narciso Clavería, decreed the systematic distribution of surnames and the implementation of the Spanish naming system for the Filipinos. This produced the Catálogo
