It has been termed an insurgency, a revolution, a guerrilla war, and a conventional war. As David J. Silbey demonstrates in this taut, compelling history, the 1899 Philippine-American War was in fact all of these. Played out over three distinct conflicts - one fought between the Spanish and the allied United States and Filipino forces; one fought between the United States and the Philippine Army of Liberation; and one fought between occupying American troops and an insurgent alliance of often divided Filipinos - the war marked America's first steps as a global power and produced a wealth of lessons learned and forgotten. In A War of Frontier and Empire , Silbey traces the rise and fall of President Emilio Aguinaldo, as Aguinaldo tries to liberate the Philippines from colonial rule only to fail, devastatingly, before a relentless American army. He tracks President McKinley's decision to commit troops and fulfill a divinely inspired injunction to "uplift and civilize" despite the protests of many Americans. Most important, Silbey provides a clear lens to view the Philippines as, in the crucible of war, it transforms itself from a territory divided by race, ethnicity, and warring clans into a cohesive nation on the path to independence.
