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.
Treaty of Manila (1946)
Commodore Dewey's decisive victory in the Battle of Manila Bay on May 1, 1898 marked the fall of Spanish inshore defenses in the Philippines. Dewey's victory was later followed by an alliance between U.S. forces and Filipino forces commanded by General Emilio Aguinaldo. Aguinaldo declared Philippine independence on June 12, 1898 and went on to form the First Philippine Republic. Aguinaldo's proclamation of independence was never recognized by either Spain or the U.S.
