Spanish government was highly dependent on the influx of silver from Mexico and Peru, since it supported the government in Manila, to continue the Christianization of the archipelago. The most difficult challenges for the missionaries were the dispersion of the Filipinos and the wide variety of languages and dialects. The geographical isolation forced the Filipino population into numerous small villages, and every other province supported a different language. Furthermore, frequent privateering from Japanese Wokou pirates and slave-raiding by Muslims blocked Spanish attempts to Christianize the archipelago, and to offset the disruption of continuous warfare with them, the Spanish militarized the local populations, importing soldiers from Latin America, and constructed networks of fortresses across the islands. As the Spanish and their local allies were in a state of constant war against pirates and slavers, the Philippines became a drain on the Vice-royalty of New Spain in Mexico City, which paid to maintaining control of Las Islas Filipinas in lieu of the Spanish crown. Religious orders The Philippines is home to many of the world's major religious congregations, these include the Redemptorists, Augustinians, Recollects, Jesuits, Dominicans, Benedictines, Franciscans, Carmelites, Divine Word Missionaries, De La Salle Christian Brothers, Salesians of Don Bosco, the indigenous Religious of the Virgin Mary, and Clerics Regular of St. Paul are known as Barnabites. During the Spanish colonial period, the five earliest regular orders assigned to Christianize the natives were the Augustinians, who came with Legazpi, the Discalced Franciscans (1578), the Jesuits (1581), the Dominican friars (1587) and the Augustinian Recollects (simply called the Recoletos, 1606). In 1594, all had agreed to cover a specific area of the archipelago to deal with the vast dispersion of the natives. The Augustinians and Franciscans mainly covered the Tagalog country while the Jesuits had a small area. The Dominicans encompassed the Parian. The provinces of Pampanga and Ilocos were assigned to the Augustinians. The province of Camarines went to the Franciscans. The Augustinians and Jesuits were also assigned the Visayan Islands. The Christian conquest had not reached Mindanao due to a highly resistant Muslim community that existed pre-conquest. The task of the Spanish missionaries, however, was far from complete. By the seventeenth century, the Spaniards had created about 20 large villages and almost completely transformed the native lifestyle. For their Christian efforts, the Spaniards justified their actions by claiming that the small villages were a sign of barbarism and only bigger,
