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.
Emilio Aguinaldo
Aguinaldo retired from public life for many years. In 1935, when the Commonwealth of the Philippines was established in preparation for Philippine independence, he ran for president in the Philippine presidential election, 1935, but lost by a landslide to Manuel L. Quezon. The two men formally reconciled in 1941, when President Quezon moved Flag Day to June 12, to commemorate the proclamation of Philippine independence.
