In accordance with the idea that underlies this collection this Introduction will not discuss the Philippine question of today nor Philippine life during the last half century, nor will it give a short history of the Islands since the conquest. For all these the reader may be referred to recent publications like those of Foreman, Sawyer, or Worcester, or earlier ones like those of Bowring and Mallat, or to the works republished in the series. The aim of the Introduction is rather to give the discovery and conquest of the Philippines their setting in the history of geographical discovery, to review the unparalleled achievements of the early conquerors and missionaries, to depict the government and commerce of the islands before the revolutionary changes of the last century, and to give such a survey, even though fragmentary, of Philippine life and culture under the old régime as will bring into relief their peculiar features and, if possible, to show that although the annals of the Philippines may be dry reading, the history of the Philippine people is a subject of deep and singular interest. The Philippine Islands in situation and inhabitants belong to the Asiatic world, but, for the first three centuries of their recorded history, they were in a sense a dependency of America, and now the whirligig of time has restored them in their political relations to the Western Hemisphere. As a dependency of New Spain they constituted the extreme western verge of the Spanish dominions and were commonly known as the Western Islands [2] _(Las Islas del Poniente)._ Their discovery and conquest rounded out an empire which in geographical extent far surpassed anything the world had then seen. When the sun rose in Madrid, it was still early afternoon of the preceding day in Manila, and Philip II was the first monarch who could boast that the sun never set upon his dominions. [3] In one generation, 1486-1522, the two little powers of the Iberian Peninsula had extended their sway over the seas until they embraced the globe. The way had been prepared for this unparalleled achievement by the courage and devotion of the Portuguese Prince Henry the Navigator, who gave his life to the advancement of geographical discovery and of Portuguese commerce. The exploration of the west coast of Africa was the school of the navigators who sailed to the East and the West Indies, and out of the administration of the trade with Africa grew the colonial systems of later days. In the last quarter of the fifteenth century the increasing obstructions in Egypt and by the Turks to the trade with the East Indies held out a great prize to the discoverer of an all-sea route to the Spice Islands. Bartholomew Diaz and Vasco da Gama solved this problem for Portugal, but the solution offered to Spain by Columbus and accepted in 1492 revealed a New World, the Indies of the West.
