In Central Luzon, a revolutionary government was organized under General Francisco Macabulos, a Kapampangan revolutionary leader of La Paz, Tarlac. American Colonial era The Americans established a local Philippine government in the Philippines when they held the first municipal election in the country in the city of Baliwag on May 6, 1899. At the beginning of the American rule, 1899–1900, Malolos became the headquarters of the Military Governor of the Philippines at Casa Real.
