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.
Revolutionary government in the Philippines
A revolutionary government was declared by the Katipunan during the Philippine Revolution or the War for Independence of the Philippines against the Spanish colonial administration over the islands. The Tejeros Convention of 1897 saw the election of officers for a revolutionary government. The independence of the Philippines from Spain was declared by Katipunan leader, Emilio Aguinaldo, who is recognized as the first President of the country, on June 12, 1898. Six days later a revolutionary government over the Philippines was officially declared.
