Philippine–American War
In 1902, the United States Congress passed the Philippine Organic Act, which provided for the creation of the Philippine Assembly, with members to be elected by Filipino males. (Women did not have suffrage in the US or the Philippines.) This act was superseded by the 1916 Philippine Autonomy Act, which contained the first formal and official declaration of the United States government's commitment to eventually grant independence to the Philippines. The 1934 Philippine Independence Act created the Commonwealth of the Philippines the following year, a limited form of independence, and established a process ending in Philippine independence (originally scheduled for 1944, but interrupted and delayed by World War II). The United States granted independence in 1946, following World War II and the Japanese occupation of the Philippines, through the Treaty of Manila.
Tirad Pass: The Last Stand of Gen. Gregorio del Pilar
By the end of 1898, most of the country has fallen to American and Filipino forces and Aguinaldo has declared Philippine independence in his home province of Cavite. But this is ignored by both the Spanish and American authorities, and Spain formally surrenders the Philippines to the United States alone through the Treaty of Paris.
