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.
History of Manila
Having just won their independence from Spain, the Filipinos were fiercely opposed to once again being occupied. Emilio Aguinaldo proclaimed the First Philippine Republic at the Malolos Congress and had begun to build the foundations for an independent nation. Admiral Dewey, however, claimed he never recognized the Philippine Republic, as he did not have the authority to do so and did not consider it an organized government.
