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.
Dictatorial Government of the Philippines
On 12 June 1898, Aguinaldo proclaimed the independence of the Philippines at his house in Cavite El Viejo. Ambrosio Rianzares Bautista wrote the Philippine Declaration of Independence, and read this document in Spanish that day at Aguinaldo's house. On 18 June, Aguinaldo issued a decree formally establishing his dictatorial government. On June 23, Aguinaldo issued another decree, this time replacing the dictatorial government with a revolutionary government (and naming himself as President).
