The Spaniards arrived in the Philippines in the 16th century and established colonial rule that lasted until 1898. They resettled Filipinos into planned towns centered around a plaza with a church, established the Catholic faith across the islands, and developed a colonial economy based on agriculture and trade. The Spaniards educated a Filipino elite class in Spanish language and culture to help administer the colony, while the general population became known as "indios" and were expected to pay tributes and provide forced labor to the Spanish. Overall, the Spanish period unified the islands under one colonial administration and introduced European cultural influences like Christianity, the Spanish language, and new economic systems, changing Filipino life.
