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 World War II, the Philippines gained independence from the United States on 4 July 1946, but then would be tied to a neo-colonial relationship. The "Treaty of General Relations" signed on independence day itself signified the Americans' withdrawal and surrender of possession, control and sovereignty over the Philippines, except the use of their bases. It was followed by the Philippine-American Military Bases Agreement on 14 March 1947, allowing the U.S. to maintain territorial integrity and sovereignty over Clark Air Base and Subic Naval Base for the next 44 years. Clark occupied 63,103 hectares and served as the tactical operational U.S. air force installation in the entire Southeast Asian region that had the capacity to accommodate the U.S. military transport planes, which served the entire Western Pacific.
