The Philippine Declaration of Independence occurred on June 12, 1898 in the Philippines, where Filipino revolutionary forces under General Emilio Aguinaldo (later to become the Philippines' first Republican President) proclaimed the sovereignty and independence of the Philippine Islands from the colonial rule of Spain after the latter was defeated at the Battle of Manila Bay during the Spanish-American War.
The declaration, in the form of a proclamation, in the presence of a huge crowd, was done on June 12, 1898 at the ancestral home of General Emilio Aguinaldo between four and five in the afternoon in Cavite el Viejo (now Kawit), Cavite, some 30 kilometers South of Manila. The event saw the unfurling of the National Flag of the Philippines, made in Hong Kong by Mrs. Marcela Agoncillo, Lorenza Agoncillo and Delfina Herboza, and the performance of the Marcha Filipina Magdalo, as the Nation's National Anthem, now known as Lupang Hinirang, which was composed by Julian Felipe and played by the San Francisco de Malabon Marching band.
