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.

By the end of 1898, most of the country has fallen to American and Filipino forces and Aguinaldo has declared Philippine independence in his home province of Cavite. But this is ignored by both the Spanish and American authorities, and Spain formally surrenders the Philippines to the United States alone through the Treaty of Paris.
