History of the Philippines (1521–1898)
The history of the Philippines from 1521 to 1898, also known as the Spanish colonial period, was a period during which Spain controlled the Philippine islands as the Captaincy General of the Philippines, initially under New Spain until Mexican independence in 1821, which gave Madrid direct control over the area. It was also known as Spanish East Indies to the colonialists. It started with the arrival in 1521 of European explorer Ferdinand Magellan sailing for Spain, which heralded the period when the Philippines was a colony of the Spanish Empire, and ended with the outbreak of the Philippine Revolution in 1898, which marked the beginning of the American colonial era of Philippine history.
Military history of the Philippines during World War II
The Commonwealth of the Philippines was attacked by the Empire of Japan on December 8, 1941 nine hours after the attack on Pearl Harbor (the Philippines is on the Asian side of the international date line). The United States of America controlled the Philippines at the time and possessed important military bases there. The combined American-Filipino army was defeated in the Battle of Bataan and the Battle of Corregidor in April 1942, but guerrilla resistance against the Japanese continued throughout the war. Uncaptured Filipino army units, a communist insurgency and supporting American agents all played a role in the resistance. Due to the huge number of islands, the Japanese never occupied many of the smaller and more minor islands. Japanese control over the countryside and smaller towns was often tenuous at best.
