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)
The Mock Battle of Manila culminated in the formal transfer of power over the Philippines. The Philippine Proclamation of Independence on June 12, 1898 was neglected by both Spain and the U.S.. Instead, they agreed on a set of terms provided by the Treaty of Paris, to which the First Philippine Republic objected, marking the start of the Philippine-American War.
