Timeline of the Philippine–American War
The Philippine–American War, also known as the Philippine War of Independence or the Philippine Insurrection (1899–1902), was an armed conflict between Filipino revolutionaries and the government of the United States which arose from the struggle of the First Philippine Republic to gain independence following annexation by the United States. This article presents several lists of dated events leading up to, during, and following that war which are significant in that context. Most of the events listed in this article are linked to other articles containing more detail.
Spanish–American War period 
Spanish–American War, the Philippine Revolution had been suspended by the Pact of Biak-na-Bato. Following on that pact, Emilio Aguinaldo, who had been leader of the Katipunan, was in exile in Hong Kong along with other revolutionary leaders. Some revolutionary generals remained in the Philippines and continued the revolution. One, General Francisco Makabulos, established a Central Executive Committee to serve as the interim government until a more suitable one was created. The advent of the Spanish–American War brought about an influx of U.S. forces into the Philippines, Aguinaldo's return to the Philippines, and Aguinaldo's resumption of a leadership role in the revolution. As the Spanish–American War continues, Aguinaldo proclaims Philippine independence and establishes a series of insurgent governments. On December 10, 1898, the U.S. and Spain sign the Treaty of Paris, ending the war. In one provision of the treaty, Philippines to the U.S.

The Philippine–American War 
Start and ending dates 
Armed conflict erupted in Manila between U.S. and Filipino forces on February 4, 1899. On that date, Emilio Aguinaldo issued a proclamation ordering, in part, "[t]hat peace and friendly relations with the Americans be broken and that the latter be treated as enemies, within the limits prescribed by the laws of war." The ending of the war was not formalized in a treaty by which it can be dated. Emilio Aguinaldo was captured by U.S. forces on March 23, 1901, and swore allegiance to the U.S. on April 1, appealing to all Filipinos to accept the "sovereignty of the United States ...". Armed conflict continued, however, until the surrender of the last Filipino general on April 13, 1902. On July 4, 1902, U.S. President Theodore Roosevelt proclaimed a full and complete pardon and amnesty to all people in the Philippine archipelago who had participated in the conflict, and that July 4 date is often mentioned as the ending date of the war. For purposes of this article, the war is considered to have begun on February 4, 1899, and to have ended on July 4, 1902.
