Spanish was the official language of the Philippines from the beginning of Spanish rule in the late 16th century, through the Philippine–American War (1899-1902) and subsequent United States colonization and remained co-official after independence in 1946, along with Filipino and English, until 1973. Its status was initially removed in 1973 by a constitutional change, but after a few months it was re-designated an official language again by a presidential decree. With the present Constitution, Spanish became designated as an auxiliary or "optional and voluntary language". During the period of Spanish colonization (1565–1898), it was the language of government, trade, education, and the arts. With the establishment of a free public education system set up by the colonial government in the mid-19th century, a class of native Spanish-speaking intellectuals called the Ilustrados was formed, which included historical figures such as José Rizal, Antonio Luna and Marcelo del Pilar. By the end of Spanish rule, a significant number of urban and elite populations were conversant in Spanish, although only a minority of the total population had knowledge of the language. It served as the country's first official language as proclaimed in the Malolos Constitution of the First Philippine Republic in 1899 and continued to be widely used during the first few decades of U.S. rule (1898–1946). Gradually however, the American government began promoting the use of English at the expense of Spanish, characterizing it as a negative influence of the past. By the 1920s, English became the primary language of administration and education. While it continued to serve as an official language after independence in 1946, the state of Spanish continued to decline until its removal from official status in 1973. Today, the language is no longer present in daily life and despite interest in some circles to learn or revive it, it continues to see dwindling numbers of speakers and influence. Roughly 548,000 Filipinos (less than 0.5% of the population) are estimated to be proficient in Spanish as of 2020. It is regulated by the Academia Filipina de la Lengua Española, the main Spanish-language regulating body in the Philippines, and a member of the Asociación de Academias de la Lengua Española, the entity which regulates the Spanish language worldwide. Background Overview Spanish was the language of government, education and trade throughout the three centuries of Spanish rule and continued as the country's lingua franca until the first half of the 20th
