The Philippine–American War, also known as the Philippine Insurrection, erupted after the Spanish–American War concluded in December 1898. Following the Treaty of Paris, which saw the United States annex the Philippine Islands, tensions escalated with Filipino nationalists who had declared independence and established the First Philippine Republic in January 1899. The U.S. refusal to recognize their sovereignty led to hostilities beginning on February 4, 1899, with the Battle of Manila. Although the U.S. officially declared the war ended on July 4, 1902, sporadic fighting continued for years. This brutal conflict, marked by atrocities and heavy civilian casualties, was fueled by American desires for imperial control and Filipino resistance against perceived foreign domination. The war reshaped the Philippines' political landscape and sparked significant debate within the United States over the ethics of imperialism. The conflict prompted discussions among U.S. political figures and activists, who questioned whether it contradicted foundational democratic values.
Prelude to war and initial hostilities
The First Philippine Republic was officially declared on January 21, 1899, but its pursuit of recognition and peace was short-lived due to rising tensions with the United States. By January 31, President Emilio Aguinaldo had ordered the cultivation of idle lands for food production, anticipating conflict with American forces. The first shots of what would become the Philippine-American War were fired by Private William W. Grayson on February 4, 1899, along Sociego Street, marking the beginning of open hostilities and leading to the 1899 Battle of Manila. Aguinaldo's declaration severed peace with the Americans and recognized them as enemies under the laws of war. Filipino General Isidoro Torres attempted to negotiate a ceasefire through General Otis, but these efforts were rebuffed, leading to further military actions.
American military strategy and Filipino resistance
The U.S. justified its actions in the Philippines as a mission to liberate and protect the local population from European powers, a stance articulated by Senator Albert J. Beveridge. After the initial clashes, American naval forces bombarded Iloilo on February 11, 1899, causing significant damage and casualties among Filipinos. As American forces secured Manila and advanced north, their strategy adapted to counter Filipino guerrilla tactics. By September 1899, American forces began focusing on suppressing Filipino resistance through control of strategic areas and implementing harsh measures such as internment. General Otis, despite directives to avoid conflict, pursued a strategy of relentless aggression, often disregarding Washington’s instructions and suppressing reports of American misconduct.
Shift to guerrilla warfare
Initially, Filipino forces engaged in conventional warfare but faced overwhelming American military superiority. By November 1899, Aguinaldo and his generals adopted guerrilla tactics, making American control increasingly challenging and leading to bloody engagements such as ambushes and raids. Although the guerrilla campaign offered hope for a Filipino victory, it was ultimately undermined by American military responses and the election of President McKinley, who was committed to maintaining control over the islands. Despite early successes, Filipino resistance faced severe setbacks as American strategy focused on crushing the insurgency.
Decline of the first Philippine Republic and martial law
As American forces continued to prevail in both conventional and guerrilla warfare, the Philippine government’s base of operations shifted multiple times. On June 24, 1900, U.S. Military Governor MacArthur offered amnesty to insurgents who surrendered, but the conflict dragged on. Aguinaldo's capture by Brigadier General Frederick Funston on March 23, 1901, was a pivotal blow to the Filipino cause. Aguinaldo’s surrender and subsequent oath of allegiance to the United States marked a significant decline in organized resistance, though sporadic guerrilla activities continued. Martial law, declared on December 20, 1900, under MacArthur’s authority, further tightened American control, targeting both guerrillas and civilian supporters.
Political atmosphere and aftermath
The formal end of the conflict was proclaimed by President Theodore Roosevelt on July 4, 1902, though minor uprisings persisted. The American government, having consolidated control, transitioned from military to civilian rule, inaugurating the civil government with William Howard Taft as its first governor. Reforms included establishing a public school system and disestablishing the Catholic Church. Despite continued resistance in certain regions and sporadic Moro insurgencies, American dominance was largely secured. The Philippines would eventually gain autonomy in 1935 and full independence in 1946 following World War II. The Schurman Commission, established in 1899, had determined that the Philippines was not ready for self-governance and recommended a gradual transition to civilian rule, including a bicameral legislature and a system of public education under American oversight. In 1900, the Taft Commission began reforms, including improvements in civil service and infrastructure. American opposition to imperialism, voiced by figures like William Jennings Bryan and Mark Twain, criticized annexation on democratic grounds. Filipinos were divided: some, like Pedro Paterno, supported American rule for stability, while many resisted, leading to ongoing insurgency. The Moro Rebellion, which began in 1902, ended in 1913 with the defeat of Moro forces. Land reforms reduced the Catholic Church's influence, and educational reforms began with the Thomasites in 1901. The path to independence progressed through the Jones Act of 1916 and the Tydings-McDuffie Act of 1934. Despite delays from World War II, the Treaty of Manila in 1946 officially recognized Philippine independence.
