Philippine Declaration of Independence
Following the end of World War II, the United States granted independence to the Philippines on 4 July 1946 via the Treaty of Manila. July 4 was observed in the Philippines as "Independence Day" until August 4, 1964 when, upon the advice of historians and the urging of nationalists, President Diosdado Macapagal signed into law Republic Act No. 4166 designating June 12 as the country's "Independence Day". June 12 had previously been observed as "Flag Day" and many government buildings are urged to display the Philippine Flag in their offices.
List of Presidents of the Philippines
Manuel Roxas (1946–1948) followed Picar when he won the first post-war election in 1946. He became the first president of the independent Philippines when the Commonwealth ended on July4 of that year. The Third Republic was ushered in and would cover the administrations of the next five presidents, the last of which was Ferdinand Marcos (1965–86), who performed a self-coup by imposing martial law in 1972. The dictatorship saw the birth of Marcos' New Society and the Fourth Republic. His tenure lasted until 1986 when he was deposed in the People Power Revolution. The current constitution came into effect in 1987, marking the beginning of the Fifth Republic.
