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.
Western imperialism in Asia
The Filipinos, who assisted U.S. troops in fighting the Spanish, wished to establish an independent state and, on June 12, 1898, declared independence from Spain. In 1899, fighting between the Filipino nationalists and the U.S. broke out; it took the U.S. almost fifteen years to fully subdue the insurgency. The U.S. sent 70,000 troops and suffered thousands of casualties. The Filipinos insurgents, however, suffered considerably higher casualties than the Americans. Most casualties in the war were civilians dying primarily from disease.
