The Negritos are believed to have migrated to the Philippines some 30,000 years ago from Borneo, Sumatra, and Malaya. The Malayans followed in successive waves. These people belonged to a primitive epoch of Malayan culture, which has apparently survived to this day among certain groups such as the Igorots. The Malayan tribes that came later had more highly developed material cultures.

In the 14th cent. Arab traders from Malay and Borneo introduced Islam into the southern islands and extended their influence as far north as Luzon. The first Europeans to visit (1521) the Philippines were those in the Spanish expedition around the world led by the Portuguese explorer Ferdinand Magellan. Other Spanish expeditions followed, including one from New Spain (Mexico) under López de Villalobos, who in 1542 named the islands for the infante Philip, later Philip II.
