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.

After Emilio Aguinaldo issued the Philippine Declaration of Independence on June 12, 1898, at Kawit, Cavite, there still was uneasy peace around Manila. Filipinos revolutionaries felt that Spain simply ceded the Philippines to the United States who were determined to take over from where the Spaniards left off. American forces started to come between June and July 1898 where 8,000 were deployed around Manila and 11,000 more deployed along the Zapote Line.
