The rule of the United States over the Philippines had two phases.
The first phase was from 1898 to 1935, during which time Washington defined its colonial mission as one of tutelage and preparing the Philippines for eventual independence. Political organizations developed quickly, and the popularly elected Philippine Assembly (lower house) and the U.S.-appointed Philippine Commission (upper house) served as a bicameral legislature. The ilustrados formed the Federalista Party, but their statehood platform had limited appeal. In 1905 the party was renamed the National Progressive Party and took up a platform of independence. The Nacionalista Party was formed in 1907 and dominated Filipino politics until after World War II. Its leaders were not ilustrados. Despite their “immediate independence” platform, the party leaders participated in a collaborative leadership with the United States. A major development emerging in the post-World War I period was resistance to elite control of the land by tenant farmers, who were supported by the Socialist Party and the Communist Party of the Philippines. Tenant strikes and occasional violence occurred as the Great Depression wore on and cash-crop prices collapsed.
The second period of United States rule—from 1936 to 1946—was characterized by the establishment of the Commonwealth of the Philippines and occupation by Japan during World War II. Legislation passed by the U.S. Congress in 1934 provided for a 10-year period of transition to independence. The country’s first constitution was framed in 1934 and overwhelmingly approved by plebiscite in 1935, and Manuel Quezon was elected president of the commonwealth. Quezon later died in exile in 1944 and was succeeded by Vice President Sergio Osmeña.
Japan attacked the Philippines on December 8, 1941, and occupied Manila on January 2, 1942. Tokyo set up an ostensibly independent republic, which was opposed by underground and guerrilla activity that eventually reached large-scale proportions. A major element of the resistance in the Central Luzon area was furnished by the Huks (short for Hukbalahap, or People’s Anti-Japanese Army). Allied forces invaded the Philippines in October 1944, and the Japanese surrendered on September 2, 1945.
World War II was demoralizing for the Philippines, and the islands suffered from rampant inflation and shortages of food and other goods. Various trade and security issues with the United States also remained to be settled before Independence Day. The Allied leaders wanted to purge officials who collaborated with the Japanese during the war and to deny them the right to vote in the first postwar elections. Commonwealth President Osmeña, however, countered that each case should be tried on its own merits. The successful Liberal Party presidential candidate, Manual Roxas, was among those collaborationists. Independence from the United States came on July 4, 1946, and Roxas was sworn in as the first president. The economy remained highly dependent on U.S. markets, and the United States also continued to maintain control of 23 military installations. A bilateral treaty was signed in March 1947 by which the United States continued to provide military aid, training, and matériel.
