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.
Philippine Revolution
As the First Philippine Republic was never recognized as a sovereign state, and the United States never formally declared war, the conflict was not concluded by a treaty. On July 2, 1902, the United States Secretary of War telegraphed that since the insurrection against the United States had ended and provincial civil governments had been established throughout most of the Philippine archipelago, the office of military governor was terminated. On July 4, Theodore Roosevelt, who had succeeded to the U.S. Presidency after the assassination of William McKinley, proclaimed an amnesty to those who had participated in the conflict. On April 9, 2002, Philippine President Gloria Macapagal Arroyo proclaimed that the Philippine–American War had ended on April 16, 1902 with the surrender of General Miguel Malvar, and declared the centennial anniversary of that date as a national working holiday and as a special non-working holiday in the Province of Batangas and in the Cities of Batangas, Lipa and Tanauan.
