Military history of the Philippines traces armed conflict across the Philippines from pre-colonial inter-polity warfare through colonial struggles with Spain and United States, the crucible of World War II against Imperial Japan, post-independence internal conflicts involving communist and Islamist insurgencies, and contemporary roles in regional security and peacekeeping. It encompasses naval engagements, land battles, guerrilla campaigns, strategic treaties, and evolving institutions such as the Armed Forces of the Philippines and coast guard. The narrative intertwines figures, battles, and laws that shaped sovereignty, social order, and foreign relations.

Pre-Colonial Warfare and Indigenous Polities

Maritime and terrestrial conflict among archipelagic polities like the Kingdom of Tondo, Sultanate of Sulu, Kingdom of Butuan, and Rajahnate of Cebu featured naval raids, fortified settlements, and alliances. Indigenous war leaders such as Lapu-Lapu engaged in pivotal clashes like the Battle of Mactan against Ferdinand Magellan and Magellan Expedition forces. Weapons and tactics included the kampilan, kris, and native war canoes called balangay, while social institutions like the datu hierarchy organized levies and raiding parties. Regional interactions involved trade and conflict with Srivijaya, Majapahit, and Ming dynasty envoys, influencing fortification and naval strategy.

Spanish Colonial Period and the Philippine Revolution

Spanish conquest initiated sustained campaigns led by figures such as Miguel López de Legazpi and confrontations at sites including Manila and Cebu. Colonial military structure combined Spanish Navy expeditions, local auxiliary forces, and fortifications like Fort Santiago and Intramuros. Resistance encompassed localized revolts like the Dagohoy Rebellion and broader movements culminating in the Philippine Revolution under leaders Andrés Bonifacio and Emilio Aguinaldo, with engagements such as the Battle of Manila (1896) and the declaration of the First Philippine Republic. The period concluded with the Treaty of Paris (1898), transferring sovereignty claims amid the outbreak of the Philippine–American War.

American Colonial Period and World War II

American rule established institutions like the Philippine Constabulary and later the Philippine Army under the National Defense Act of 1935, preparing for modern warfare. During World War II, combined actions by Douglas MacArthur's USAFFE and Filipino units faced the Invasion of the Philippines (1941–42) and battles such as Bataan and Corregidor, leading to the Bataan Death March. An extensive guerrilla resistance network including leaders like Carlos P. Romulo and regional commanders sustained operations until the Philippine Liberation and Battle of Leyte during Invasion of Leyte (1944), facilitating MacArthur's return and contributing to the eventual surrender of Imperial Japan.

Post-Independence Armed Forces and Internal Conflicts

Following the 1946 independence, the Armed Forces of the Philippines reorganized amid nascent strategic alignments, exemplified by the Mutual Defense Treaty (1951) with the United States, and internal upheavals including coup attempts. The Cold War era saw protracted insurgency by the Communist Party of the Philippines and its armed wing, the New People's Army, engaging in guerrilla warfare across provinces like Negros and Samar. Separatist and Islamist movements like the Moro National Liberation Front and later the Moro Islamic Liberation Front contested authority in Mindanao, producing clashes such as the Siege of Marawi and negotiations culminating in the Bangsamoro Organic Law. Notable leaders and incidents include Ferdinand Marcos's declaration of Martial Law and the People Power Revolution led by Benigno Aquino Jr.'s supporters and figures like Corazon Aquino.

Counterinsurgency, Counterterrorism, and Modernization

Philippine forces have pursued combined counterinsurgency and counterterrorism campaigns integrating the Philippine National Police and Armed Forces of the Philippines, with operations against groups such as Abu Sayyaf, Jemaah Islamiyah, and Maute group. Key episodes include the Zamboanga City crisis and operations leading to the death of leaders like Isnilon Hapilon. Modernization efforts involve acquisitions from suppliers like United States Department of Defense programs, regional procurements from South Korea and Japan, and reforms under laws such as the AFP Modernization Act. Emphasis on naval capability expansion, air force upgrades including acquisitions like the FA-50 fighters, and enhanced Philippine Coast Guard assets reflect strategic responses to tensions in the South China Sea involving People's Republic of China and disputes like the Scarborough Shoal standoff.

International Peacekeeping and Regional Security Participation

The Philippines has contributed troops and observers to United Nations missions including deployments to East Timor and Sudan, and engaged in multinational exercises like Balikatan with the United States Armed Forces and Exercise Malabar-adjacent activities. Participation in bodies such as the Association of Southeast Asian Nations and trilateral dialogues with Japan and Australia supports capacity-building and humanitarian assistance/disaster relief frameworks evidenced during responses to the 2004 Indian Ocean earthquake and tsunami and Typhoon Haiyan (Yolanda). Bilateral agreements including the Enhanced Defense Cooperation Agreement (2014) shape basing and interoperability, while naval diplomacy and coast guard cooperation address piracy, fisheries enforcement, and freedom of navigation in regional waters.
