List of legislatures of the Philippines
The Philippines has been governed by legislatures since 1898. The country has had different setups, with legislatures under the presidential system and the parliamentary system, and with legislatures having one or two chambers.
The first national legislature in the Philippines was the Malolos Congress that convened in the Barasoain Church at Malolos, Bulacan. Convened after the declaration of independence from Spain at the height of the Philippine Revolution, the Congress ratified the declaration, and drafted a constitution. With the capture of President Emilio Aguinaldo during the ensuing Philippine–American War, the unrecognized First Philippine Republic fell.
The Americans then sent several commissions to assess the situation; these eventually became the Philippine Commission. With the passage of the Philippine Bill of 1902, the Philippine Commission eventually became an appointive upper house of the new Philippine Legislature, of which the wholly elected Philippine Assembly was the lower house. The passage of the Philippine Autonomy Act instituted a mostly elective Senate as the upper house, with the House of Representatives as the lower house. This set up continued until the 1935 Constitution of the Philippines was set into force, creating a unicameral National Assembly under the Commonwealth of the Philippines. Amendments that took effect in 1941 restored the bicameral setup, creating the Commonwealth Congress. However, World War II intervened, and legislators elected in 1941 were not be able to serve. The invading Japanese set up the Second Philippine Republic that convened its own National Assembly.
The Allies reconquered the Philippines and the legislators elected in 1941 who are either still alive or are not arrested for collaboration convened in 1945. The Americans granted independence on July 4, 1946, and the Commonwealth Congress was renamed as Congress of the Republic of the Philippines. This will continue until the declaration of martial law by President Ferdinand Marcos on September 23, 1972, which effectively dissolved Congress. Marcos then exercised legislative power; his 1973 Constitution created the unicameral Batasang Pambansa, a parliament. The Batasang Pambansa first convened in 1978, and will continue to exist until the 1986 People Power Revolution that overthrew Marcos from power. President Corazon Aquino appointed a constitutional commission that drafted the 1987 Constitution which restored the bicameral Congress with the presidential system of government.
