The Philippine–American War, also known as the Philippine War of Independence or the Philippine Insurrection (1899–1902),^[1] 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 the Philippines being acquired by the United States from Spain.^[2][3] This article lists significant events from before, during, and after that war, with links to other articles containing more detail.

• 21–25 April – The Spanish–American War begins. War is declared by the United States and Spain.
• 1 May – Commodore George Dewey decisively defeated the Spanish fleet commanded by Patricio Montojo in the Battle of Manila Bay.

Prior to the Spanish–American War, the Philippine Revolution against Spain had been suspended by the Pact of Biak-na-Bato. Following on that pact, Emilio Aguinaldo, who had been leader of the Katipunan, went into exile in Hong Kong along with other revolutionary leaders. Some revolutionaries remained in the Philippines and continued the revolution. When the Spanish–American War broke out, American forces sailed for the Philippines and decisively defeated the Spanish Navy. Aguinaldo then returned to the Philippines, and resumed a leadership role in the revolution. As the Spanish–American War continues, Aguinaldo proclaims Philippine independence and establishes an insurgent government.

Depending on events chosen to mark the beginning and the end of the war, a number of different start and ending dates can be given. For purposes of this article, the war is considered to have begun on 4 February 1899, and to have ended on 4 July 1902.

Armed conflict erupted in Manila between U.S. and Filipino forces on 4 February 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."^[20] On 2 June 1899, the Malolos Congress enacted and ratified a Declaration of War on the United States, which was publicly proclaimed on that same day by Pedro Paterno, President of the Assembly.^[21]

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 23 March 1901, and swore allegiance to the U.S. on 1 April, 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 13 April 1902.^[22] On 4 July 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.^[23] On 9 April 2002, Philippine President Gloria Macapagal Arroyo proclaimed that the Philippine–American War had ended on 16 April 1902 with the surrender of General Miguel Malvar.^[24]

However, despite these proclamations from the Americans and ilustrado elite, the war continued across the archipelago for over a decade. Bands of guerrillas, millenarian movements and other resistance groups continued to roam the countryside, still clashing with American Army or Philippine Constabulary patrols. American troops and the Philippine Constabulary continued hostilities against such resistance groups until 1913.^[25][26] Some other sources describe post-1902 actions in Mindanao as a separate conflict.^[27]
