The Philippines’ conflict history begins with Spanish conquest, which joined a diverse archipelago under colonial rule while fostering the Catholic institutions and educated elite from which modern nationalism emerged. Its defining historical process has been the struggle for self-government under successive empires. The revolution against Spain proclaimed Filipino sovereignty, but the Philippine–American War placed the islands under a new colonial power and fixed the United States as the country’s principal external partner. This history gave the Philippines a singular place in Asia: a post-colonial democracy deeply linked to the United States, yet shaped by local movements for national autonomy. Ferdinand Marcos’s martial-law regime tested that inheritance. The People Power Revolution of 1986 restored democratic institutions and became a global model of nonviolent regime change, but its incomplete social reforms left the oligarchic structures that still complicate Philippine democracy.
During 2025, the Philippines conflict continued at low intensity, with government forces fighting the communist CPP insurgency and Islamic State-linked groups. UCDP recorded 197 battle-related deaths, including 35 civilians.
The World Map of Conflict uses two complementary datasets from the Uppsala Conflict Data Program (UCDP) to visualise conflict per country.
The colour coding of the overview base map is derived from the UCDP Georeferenced Event Dataset (GED), which contains fully verified conflict data aggregated at the country level. UCDP publishes the GED annually (typically May–June of the following year) to allow careful validation of every recorded event.
The map on this country page draws from the UCDP Candidate Events Dataset (CED), which includes the most recent reported events and provides a near-real-time overview of conflict developments. Because these events are still under verification, the data should be considered preliminary.
Historical Lenses
To understand Philippines’s conflict history, it is first important to understand what kind of country it is. Historians often explain the same country in different ways depending on what they believe are the main forces driving history. Each historical lens below offers a different, evidence-based interpretation of the country’s development.
The interpretation most widely accepted by historians, based on mainstream historical research and university scholarship. It reflects broad areas of agreement while acknowledging where historians disagree.
The Philippines is an archipelago of more than 7,000 islands in maritime Southeast Asia, strung between the South China Sea and the Pacific Ocean, home to roughly 115 million people speaking well over a hundred languages. Its people are Malay-Austronesian in origin, organized before outside contact into small kin-based communities called barangays (the word survives today as the name of the smallest unit of Philippine local government), with no single ruler over the islands as a whole. The mainstream account of Philippine history begins with the arrival of Spanish conquest and settlement in the sixteenth century, which for the first time bound the scattered islands into a single administrative unit, centred on the new capital of Manila. Roman Catholic missionary work converted most of the lowland population, producing the only majority-Christian nation in Asia — a fact that still marks the country out from its neighbours. In the far south, the Muslim sultanates of Mindanao and the Sulu Archipelago resisted conversion and conquest for three centuries, a resistance that has never fully been resolved. Historians read the country’s whole history since as the working-out of that founding act: an archipelago stitched into a single state from outside, whose full internal unity remains, even now, a project still under construction.
Teodoro A. Agoncillo, History of the Filipino People (8th ed., 1990); William Henry Scott, Barangay: Sixteenth-Century Philippine Culture and Society (1994).
Five thresholds, in the mainstream account, reset the structure of the Philippines. The first was Spanish colonization, begun in 1565 and consolidated with the founding of Manila in 1571, which for the first time bound the archipelago’s barangays — small kin-based settlements — under one crown and one church. The second was the Philippine Revolution of 1896, in which a movement led by the Spanish-educated elite, including Emilio Aguinaldo, overthrew Spanish rule and, briefly, declared independence in 1898. The third was the Philippine-American War of 1899–1902, in which the United States crushed that new republic and replaced it with its own colonial administration, importing English-language schooling and American-style institutions that still shape the country’s laws and politics. The fourth was the Japanese occupation of 1942–45, which devastated Manila and interrupted the transition to full independence, granted in 1946. The fifth was the martial law regime of Ferdinand Marcos (1972–1986) and its overthrow in the 1986 People Power Revolution, a mass uprising that restored elected government and became the founding myth of the modern Philippine republic. Each threshold changed who held power over the islands and on what terms, which is why historians treat them, rather than any single year, as the structural spine of the national story.
Teodoro A. Agoncillo, History of the Filipino People (8th ed., 1990); William Henry Scott, Barangay: Sixteenth-Century Philippine Culture and Society (1994).
In the mainstream account, the state was built well before a shared Filipino nation existed to inhabit it. Spanish colonial administration created the first common structure over the islands — a governor in Manila, a network of parish towns, a single legal and religious order — centuries before most of the people living under it thought of themselves as one people. A national consciousness only began to form in the nineteenth century, forged largely in reaction to colonial rule itself: the Spanish-educated elite known as the ilustrados (literally, the “enlightened ones”) began imagining a shared Filipino identity that cut across the islands’ many ethnolinguistic groups, and that identity hardened into a fighting nationalism during the Revolution of 1896 and the war against the United States that followed. Independence in 1946 completed the transfer of the colonial state into Filipino hands, but it inherited a nation whose binding was recent and incomplete. The mountainous Cordillera highlands and, above all, the Muslim south — never fully conquered by Spain and never absorbed into the Catholic-majority national story — remained, and remain, only partially joined to the state that claims them. Here the state plainly preceded the nation, and produced it only unevenly.
Teodoro A. Agoncillo, History of the Filipino People (8th ed., 1990); William Henry Scott, Barangay: Sixteenth-Century Philippine Culture and Society (1994).
The long-term force the mainstream identifies is the repeated, unfinished project of binding a fragmented archipelago into a single governed nation. Spain began it by imposing one administration and one church on thousands of islands and scores of language groups; the United States continued it with a common school system, a common language of government, and American-style elections; and the independent Philippine state has continued it since, with mixed success, through decades of Manila-centred governance. At every stage the same challenge recurs: island geography, linguistic diversity, and, in the south, a religious frontier the state has never fully crossed, keep pulling against the centre’s efforts to integrate the whole. The martial law period and its overthrow, and today’s negotiated autonomy arrangements for the Muslim south, are read in this light as the latest instalments of the same long argument between a Manila-based centre seeking to govern the whole archipelago and peripheries — highland and island, ethnic and religious — that have never been fully drawn in. What best explains the Philippines over time, on this account, is not any single event but this recurring, still-open process of national integration, attempted anew by each generation of rulers.

Alternative interpretations developed by respected historians that challenge or expand the mainstream view. These perspectives highlight debates within historical scholarship rather than presenting a single accepted explanation.
A revisionist reading challenges the standard story that Philippine nationhood was forged chiefly by an educated elite awakening a sleeping nation to Enlightenment ideas of liberty. The historian Reynaldo Ileto has argued that for the ordinary peasants and labourers who actually filled the ranks of the 1896 Revolution against Spain, the meaning of revolt came not from elite political theory but from the pasyon — the sung narrative of Christ’s suffering, death, and resurrection recited every Holy Week — which supplied a ready-made framework of suffering, sacrifice, and coming deliverance that the poor could apply directly to their own condition under colonial rule. On this account the Revolution drew much of its popular force from folk Catholic religious imagination, not from the ilustrado (Spanish-educated elite) pamphlets historians have traditionally credited. A second, complementary challenge, from the historian Alfred McCoy, argues that Philippine political history is better explained by the continuous grip of a small number of landed family dynasties on state power than by any story of national awakening. Both readings reweigh the same events rather than deny them; mainstream historians still credit elite organisation and leadership with shaping the Revolution’s actual institutions, and dispute how far a folk religious framework, rather than political calculation, drove events on the ground.
Reynaldo Ileto, Pasyon and Revolution: Popular Movements in the Philippines, 1840–1910 (1979); Alfred W. McCoy (ed.), An Anarchy of Families: State and Family in the Philippines (1993).
The revisionist account keeps the same run of turning points the mainstream uses — the Spanish conquest, the 1896 Revolution, the Philippine-American War, martial law, the 1986 restoration of democracy — but shifts the weight from national awakening to elite continuity. Spanish rule is reread as the moment that created a landed local elite, the principalía (the Spanish-recognised class of native town leaders), who administered the colony’s towns and taxes on Spain’s behalf and who quietly became the ancestors of many of the country’s modern political families. American colonial rule, on this account, entrenched rather than dissolved that elite by introducing competitive elections that only propertied, literate men could vote in or run for — handing formal democracy to the same families who had prospered under Spain. Martial law under Ferdinand Marcos is read not as a rupture from this pattern but as one family’s attempt to monopolise, for itself, an entire system of patronage other families had long shared. And the 1986 People Power Revolution, in McCoy’s reading, restored not a clean democracy but the pre-Marcos arrangement in which a shifting cast of the same dynastic families compete for the presidency and Congress. Because it reinterprets accepted events rather than inventing new ones, this stands as serious history, though how much genuine change 1986 produced remains disputed.
Alfred W. McCoy (ed.), An Anarchy of Families: State and Family in the Philippines (1993); Reynaldo Ileto, Pasyon and Revolution (1979).
In this reading, the “nation” invoked in official memory is less a shared community that produced the state than a story elite families have used to legitimate holding onto it. Emilio Aguinaldo, who led the 1896 Revolution and declared independence in 1898, himself came from a leading landowning family in Cavite province, and many of the Revolution’s other commanders and later Commonwealth-era politicians came from the same propertied class that had thrived under Spanish rule. Political power in the Philippines, on this account, has run continuously through family-based patronage networks — clans that control local government, land, and often private armed followings across generations — rather than through a horizontal community of equal citizens. Even the 1986 uprising against Marcos, though genuinely mass-based in the streets, restored government to rival established families rather than displacing dynastic rule itself; by the 2020s, the presidency had returned to the Marcos family itself, and the vice-presidency to the Duterte family, both prominent well before and after the 1986 rupture. The “nation,” on this view, is partly an aspiration invoked at moments of crisis, while the actual continuity of Philippine political life runs through family names, not a settled national community binding state to people.
Alfred W. McCoy (ed.), An Anarchy of Families: State and Family in the Philippines (1993); Reynaldo Ileto, Pasyon and Revolution (1979).
The long-term force this school places at the centre is the durable capture of the Philippine state by a small number of land-owning family dynasties, a grip that has survived every change of ruler and regime type since the Spanish era. Colonial administration under Spain created a native landholding elite to run its towns; American rule handed that same elite competitive elections rather than displacing it; martial law nationalised one family’s version of the same patronage system; and the restoration of democracy in 1986 simply reopened competition among rival dynasties rather than ending dynastic politics altogether. In this reading, Philippine history is less the story of a nation gradually integrating itself than of a weak central state repeatedly out-manoeuvred and absorbed by locally entrenched families who control land, votes, and often armed followers in their home provinces. This is a materialist and structural interpretation, and it departs deliberately from the mainstream’s emphasis on national integration as the primary drama. Its strength is that it explains the striking persistence of a handful of family names across a century and a half of upheavals; its contested point is how much of that persistence is a cause of the country’s weak institutions, and how much is only a symptom of them.

Explains history through religion, culture, identity, political traditions, ideology and the stories societies tell about themselves. This lens asks how beliefs and shared identities have shaped historical development.
Seen through faith and identity, the Philippines is above all a Catholic country, and its Catholicism was not incidental to colonization but its chief instrument. When Spain took possession of the islands in the sixteenth century, it sent relatively few settlers; instead, Catholic religious orders — friars from orders such as the Augustinians, Dominicans, and Franciscans — carried out what the historian John Leddy Phelan called a project of “Hispanization”: converting the lowland population to Catholicism town by town, and in the process reshaping local custom, language, and daily life around the parish church and its ritual calendar. The result, over three centuries, was the only majority-Christian nation in Asia, with a folk Catholicism that fused older local beliefs with church ritual — elaborate town fiestas honouring patron saints, dramatic Holy Week processions, and healing practices that stand alongside orthodox devotion. In the south, however, the Muslim sultanates of Mindanao and the Sulu Archipelago rejected conversion outright and fought Spain to a standstill across three centuries of intermittent war, remaining religiously and politically distinct to this day. Cultural historians read Philippine identity, then, as built first through the shared experience of conversion and parish life across the Christian lowlands — and permanently marked by the one region that experience never reached.
John Leddy Phelan, The Hispanization of the Philippines: Spanish Aims and Filipino Responses, 1565–1700 (1959); Vicente L. Rafael, Contracting Colonialism: Translation and Christian Conversion in Tagalog Society under Early Spanish Rule (1988).
Seen through religion and identity, the transforming moments are moments in the life of the church and of belief. The conversion campaign of the sixteenth and seventeenth centuries fixed the cultural mould for the next three hundred years, making the parish priest — usually a Spanish friar — the most direct face of colonial authority most Filipinos ever encountered. Resistance to that same campaign in the south hardened into the long Moro Wars, in which the Muslim sultanates of Mindanao and Sulu (the name “Moro,” originally the Spanish word for “Moor,” was later reclaimed by these communities as a positive political identity) fought Spain, and later the United States, to preserve their independence and their faith. Anti-friar resentment, meanwhile, became a central grievance of the 1896 Revolution: the execution of the reformist writer José Rizal that same year, on charges pressed partly by the friars he had criticised, turned him into the movement’s foremost martyr. A formal break with Rome followed in 1902, when a nationalist splinter church, the Aglipayan church, asserted a specifically Filipino Catholicism. And in 1986, the church again stood at the centre of events, when Manila’s Cardinal Jaime Sin helped call the crowds that drove Ferdinand Marcos from power. Religion, in this reading, has repeatedly supplied the moral language of Philippine political change.
John Leddy Phelan, The Hispanization of the Philippines (1959); Vicente L. Rafael, Contracting Colonialism (1988).
On this reading, a shared Catholic identity bound the lowland Christian majority together long before political nationalism gave that unity a name. Conversion imposed common institutions across a linguistically fragmented population — the parish, the mission town or poblacion, the annual fiesta calendar honouring a local patron saint — that gave Tagalog, Cebuano, Ilocano, and dozens of other language groups a shared cultural grammar even where they shared no common tongue. Filipino nationalism, when it emerged among the Spanish-educated elite in the nineteenth century, took this religiously bounded community largely for granted and built political identity on top of it. But the same religious boundary that unified the Christian lowlands excluded, by definition, the peoples it never reached: the Muslim communities of Mindanao and Sulu, for whom a nation defined implicitly as Catholic could never be a natural home, and the animist highland peoples of the Cordillera, only lightly touched by either church or colonial administration. The modern Philippine nation, in this account, therefore formed with an inbuilt boundary along religious lines, drawn not by the state’s laws but by three centuries of conversion and its limits — a boundary that later independence movements in the south have organised around ever since.
John Leddy Phelan, The Hispanization of the Philippines (1959); Vicente L. Rafael, Contracting Colonialism (1988).
The lasting force, in this cultural and religious reading, is the continuing power of the Catholic Church as a moral and political authority, and the unresolved frontier between that Catholic majority and the Muslim south it never converted. From the friar-administered parishes of the Spanish era, through the anti-friar current inside the 1896 Revolution, to the church’s decisive role in mobilising the crowds that ended martial law in 1986, religious institutions and religious language have repeatedly supplied the vocabulary through which Filipinos have contested political power. At the same time, the line drawn three centuries ago between a converted Catholic lowland and an unconverted Muslim south has never closed: it produced the Moro Wars under Spain and the United States, resurfaced as armed rebellion against the independent Philippine state from the 1970s onward, and persists today in the negotiated autonomy of the Bangsamoro region in Mindanao. What best explains Philippine development over the long run, on this account, is neither elite politics nor geography alone but this durable religious architecture — a Catholic majority whose institutions have repeatedly reshaped national politics, standing alongside a Muslim minority whose distinct faith has kept it only partially and uneasily inside the national story.

Explains history through geography, natural resources, trade, demographics, technology and economic structures. This lens explores how the physical environment and material conditions have influenced historical change.
The shape of the Philippines is oceanic: more than 7,000 islands scattered across the western Pacific, straddling the sea lanes between the South China Sea and the open ocean beyond. That geography made the archipelago, from the moment Spain claimed it in 1565, less a territory to be farmed than a position to be held: Manila’s great natural harbour became the western terminus of the Manila-Acapulco galleon trade, a state-run shipping line that for two and a half centuries (1565–1815) carried Chinese silk and porcelain across the Pacific to Spanish Mexico in exchange for American silver. The islands themselves produced comparatively little of what moved through this trade; Manila functioned chiefly as an entrepôt — a transit port where goods were exchanged rather than made — and much of the archipelago’s own agricultural and mineral potential went undeveloped for centuries as a result. Economic historians read this founding arrangement as decisive: a colony organised from the outset around a single trans-Pacific trade route and a single dominant port, rather than around the production of the islands themselves, in a position on the map that made it valuable to outsiders — Spain, later the United States, and today several regional powers contesting the surrounding seas — for exactly the same geographic reasons in every era.
William Lytle Schurz, The Manila Galleon (1939); Benito J. Legarda Jr., After the Galleons: Foreign Trade, Economic Change and Entrepreneurship in the Nineteenth-Century Philippines (1999).
The turning points, in economic and geographic terms, follow the archipelago’s changing place in world trade. The Manila-Acapulco galleon trade, running from 1565 until Mexican independence severed it in 1815, fixed Manila as a transit port for Chinese and Spanish-American goods rather than a producer of its own exports. Its collapse forced a wrenching reorientation: from the 1830s, Manila and other ports opened to direct foreign trade, and the islands turned for the first time toward exporting their own produce — sugar, abacá (a fibre crop used for rope and, later, currency paper), and tobacco — grown on estates financed increasingly by a rising Chinese-mestizo merchant and landowning class. American colonial rule after 1898 deepened this export dependence by granting Philippine sugar and coconut products privileged, near-tariff-free access to the American market, tying the colonial economy tightly to a single buyer. That dependence long outlasted independence in 1946, and in recent decades a new form of it has emerged: millions of Filipinos now work abroad as overseas workers, and their remittances form one of the economy’s largest income streams. Each threshold answers to trade routes and markets rather than to politics alone, and the economic record — export tonnage, remittance flows, shipping lanes — tracks the pattern closely across four centuries.
Benito J. Legarda Jr., After the Galleons (1999); William Lytle Schurz, The Manila Galleon (1939).
On this reading, the sea itself shaped how the Philippine state could bind its territory together, and how unevenly it managed to do so. An archipelago has no roads between its parts; for most of its history, authority over the islands moved only as fast and as far as a ship could carry it, and Manila’s dominance as the colony’s one great port concentrated administrative and commercial power in and around the capital at the expense of everywhere else. The Visayan islands and Mindanao, farther from Manila and harder to reach, were correspondingly harder to govern, tax, or bind culturally to the centre — a pattern visible in the persistent political and economic gap between “imperial Manila” and the provinces that still shapes Philippine politics today. The Muslim sultanates of the far south, in particular, were separated from the Catholic, Manila-oriented core not only by faith but by sheer distance and difficult, current-swept seas that made sustained control expensive and slow to project. State formation, on this account, was constrained at every stage by the physical cost of governing an archipelago: a strong, wealthy centre at the hub of the trade routes, and a periphery that geography itself has always made harder to fully absorb.
Benito J. Legarda Jr., After the Galleons (1999); William Lytle Schurz, The Manila Galleon (1939).
The force that best explains Philippine development, in this reading, is the archipelago’s maritime geography, converted in turn into a colonial trade funnel, then an export-agriculture economy, and now a labour-export economy, while repeatedly limiting how tightly a Manila-based centre can bind its own territory together. The galleon era organised the islands around a single trans-Pacific route; the nineteenth-century opening to foreign trade organised them around cash-crop exports to new markets; American rule locked that export dependence to the United States; and the late twentieth century added a further layer, as millions of Filipinos left to work overseas, turning remittances into one of the country’s largest sources of income. Across every phase, the same geographic fact recurs: a nation scattered over thousands of islands is expensive and slow to govern uniformly, which is part of why authority has always pooled most thickly around Manila and thinned toward the Visayas and Mindanao. Today the same sea lanes that once carried silver and silk make the Philippines a contested maritime frontier in disputes over the South China Sea. What best explains the country over time, on this account, is neither faith nor politics alone, but a geography of scattered islands and open sea that has repeatedly determined who trades, who governs, and how far that governance actually reaches.
William Lytle Schurz, The Manila Galleon (1939); Benito J. Legarda Jr., After the Galleons (1999).
Not a fifth lens, but the point the whole engine exists to make: historians describe the same country differently because they weigh its causes differently.
The sharpest dispute concerns 1986. The consensus and cultural readings treat the People Power Revolution as a genuine rupture — a mass, church-backed uprising that ended authoritarian rule and returned the country to civilian, constitutional government. The revisionist reading, following Alfred McCoy, treats the very same event as a restoration of the pre-Marcos family oligarchy rather than a real break with dynastic politics. Same uprising, opposite verdicts on how much actually changed.
The persistence of the Muslim south’s separateness divides the lenses too. The cultural account traces it to a religious frontier — a nation implicitly defined as Catholic that a Muslim minority was never going to be absorbed into. The economic-geographic account traces the same fact to sheer distance and difficult seas, which made Mindanao and Sulu expensive for any Manila-based government to govern closely. The consensus account folds both into a broader, still-unfinished project of national integration. Three explanations, one enduring divide.
On one point all four perspectives agree: the Philippine state was substantially assembled from outside and above — first by Spain, then by the United States, then by a Manila-centred elite — rather than growing from a pre-existing national community that simply won its independence. They part on what actually did, and still does, the binding: colonial administration and shared faith (consensus and cultural), family patronage networks that outlasted every regime (revisionist), or trade routes and the cost of governing a scattered archipelago (economic-geographic).

Ileto’s “pasyon” reading of the 1896 Revolution is itself an actively debated thesis within Philippine historiography and is presented here as such, not as settled fact.
The Philippines’ internal conflict remains open, low-intensity, and active on two separate fronts. Government forces continue to fight the New People’s Army, the armed wing of the Communist Party of the Philippines, in a rebellion now well into its sixth decade; and separately, they continue operations against Islamic State-linked groups — chiefly Dawlah Islamiya and remnants of the Abu Sayyaf Group — concentrated in the western Mindanao islands of Basilan, Sulu, and Cotabato. On the communist front, the government’s peace office said in early August 2026 that it was keeping the door open to renewed exploratory talks with the CPP-NPA, even as police and army units kept up operations against remaining rebel formations, notably on Negros island in May 2026. On the Islamist front, the military has sustained regular operations against Dawlah Islamiya remnants — five wanted fighters were killed in a Cotabato encounter in early August 2026 — following earlier attacks such as a January 2025 ambush in Basilan that killed several soldiers escorting a United Nations mission. A harder-line breakaway faction, the Bangsamoro Islamic Freedom Movement, continues sporadic attacks and remains formally outside the 2014 peace settlement even as the broader autonomous Bangsamoro region works through a transition process repeatedly delayed at the ballot box, with its first regional elections now rescheduled to September 2026. An International Crisis Group assessment in March 2026 described that process as still fragile — a “moment of truth” for whether the settlement can hold the trust of the communities it is meant to bind in. The long-running Philippine project of binding a fragmented archipelago together, traced across every lens above, therefore remains, in this specific and current form, unresolved.

After centuries of Spanish rule and then US control, the Philippines became independent on 4 July 1946. According to UCDP, repression of dissent and poorly handled land redistribution helped spark early rebellion and later fed a long-running communist insurgency. A separate, older divide involves Muslim communities in the south, especially Mindanao, where a distinct “Moro” identity and calls for a homeland developed over time.
In 2024, UCDP records continued fighting between the Government of the Philippines and the Communist Party of the Philippines (CPP). Violence also persists in Mindanao involving groups operating under Islamic State (IS), including Abu Sayyaf Group (ASG), Bangsamoro Islamic Freedom Movement (BIFM), and Dawlah Islamiya. Beyond these, UCDP notes non-state clashes—often between clans or communities—frequently linked to land disputes, revenge, and local resource tensions.
UCDP reports that in 2024 fatalities in the CPP–government conflict stayed similar to the previous year, with many casualties among insurgents. A joint statement in late 2023 supported resuming peace talks, but 2024 brought no negotiation progress. IS-linked violence continued but at lower intensity than the year before. Civilians have been harmed by one-sided violence and, in some areas, displaced by fighting and feuds.

Under President Ferdinand Marcos Jr., the Philippines has asserted sovereignty in the West Philippine Sea through military modernization, transparency initiatives exposing Chinese actions, and rejecting Beijing’s maritime claims. Incidents of Chinese coast guard blocking resupply missions to Philippine outposts like Second Thomas Shoal have escalated tensions, prompting Manila to file diplomatic protests and strengthen deterrence without provoking direct conflict. The approach balances firmness with calls for diplomatic negotiations to maintain economic ties with China, essential for infrastructure under the ‘Build Better More’ program.

Manila employs ‘bamboo diplomacy’—flexible resilience—rejecting binary US-China choices per its 1987 Constitution’s independent policy mandate. Marcos bolsters US and Japan partnerships for security, secures $22.8 billion Chinese investments, and engages ASEAN for South China Sea code of conduct. This pragmatic stance prioritizes sovereignty, economic security, and dialogue, influencing regional actors while navigating elite influences and US-China tensions over Taiwan and trade routes.

The Philippine Islands became a Spanish colony during the 16th century. They were ceded to the United States in 1898 following the Spanish-American War.
Led by Emilio AGUINALDO, Filipinos conducted an insurgency against US rule from 1899 to 1902, although some fighting continued in outlying islands as late as 1913. In 1935, the Philippines became a self-governing commonwealth; Manuel QUEZON was elected president and tasked with preparing the country for independence after a 10-year transition.
The islands fell under Japanese occupation during World War II. US forces and Filipinos fought together during 1944–45 to regain control.
On 4 July 1946, the Republic of the Philippines attained its independence.
Twenty-one years of authoritarian rule under Ferdinand MARCOS ended in 1986, when a “people power” movement in Manila (“EDSA 1”) forced him into exile and installed Corazon AQUINO as president. Several coup attempts hampered her presidency, and progress on political stability and economic development faltered until Fidel RAMOS was elected president in 1992; the US closed its last military bases on the islands the same year.
Joseph ESTRADA was elected president in 1998, but his vice-president, Gloria MACAPAGAL-ARROYO, succeeded him in 2001 after his impeachment trial on corruption charges broke down and another “people power” movement (“EDSA 2”) demanded his resignation. MACAPAGAL-ARROYO was elected president in 2004; corruption allegations marred her presidency, but the Philippine economy was one of the few to avoid contraction after the 2008 global financial crisis. Benigno AQUINO III was elected president in 2010, followed by Rodrigo DUTERTE in 2016; during his term, DUTERTE pursued a controversial drug war that garnered international criticism for alleged human rights abuses. Ferdinand MARCOS, Jr. was elected president in 2022 with the largest popular vote in a presidential election since his father’s ouster.
For decades, the country has been challenged by armed ethnic separatists, communist rebels, and Islamic terrorist groups. These challenges have been particularly persistent in the southern islands and remote areas of Luzon.
The Philippines faces several overlapping internal conflicts involving the national government and various armed groups. The key drivers are long-standing political, economic, and social grievances. Insurgent groups like the Communist Party of the Philippines and Islamist or jihadist factions are seeking either revolutionary change or regional autonomy, often motivated by historical marginalization or the desire for self-determination in Mindanao and other areas. These conflicts are persistent and deeply rooted in the country’s diverse society.
According to UCDP data, there are no recorded civilian deaths from collateral violence in state-based fighting for the relevant period, but the Communist Party of the Philippines is documented as having deliberately killed eight civilians. Although overall civilian casualties appear low in the current dataset segment, this does not guarantee safety for populations in conflict-affected areas, as local conditions and reporting can vary significantly over time and by location.

The Government of the Philippines is engaged in multiple internal conflicts against insurgent and militant groups seeking control or autonomy in various regions. There is no evidence of direct large-scale civilian harm caused by the government in this dataset segment.
BIFM-K is a militant Islamist group that seeks to establish an independent Islamic state in Mindanao. The group clashes with government forces, with no significant civilian casualties recorded in the current reporting period.
The CPP, through its armed wing, seeks to overthrow the Philippine government and establish a Marxist regime. The group is responsible for targeted violence against civilians, resulting in eight recorded deliberate civilian deaths in the current data segment.
Islamic State–affiliated groups in the Philippines fight to establish Islamic law and territories outside government control. Their clashes with the state did not result in recorded civilian deaths in this reporting period, according to UCDP data.
Conflict in the Philippines is driven by long-running insurgencies involving communist, Islamist, and jihadist groups, all seeking different forms of autonomy, independence, or revolutionary change. These disputes center on historical grievances, marginalization, and competition over state control in various regions.
The Philippines gains independence from the United States, adopting a presidential republic closely tied to Washington through military bases and a 1951 Mutual Defense Treaty. Strong U.S. security links and centralized state institutions frame later internal conflicts and today’s armed struggles against communist and Islamist insurgents.
Jose Maria Sison refounds the Communist Party of the Philippines (CPP) along Maoist lines, with the New People’s Army (NPA) as its armed wing. The movement mobilizes rural grievances against the state, launching the insurgency that still underpins today’s long-running civil war.
President Ferdinand Marcos proclaims martial law, suspending civil liberties, repressing opposition, and expanding the military. Authoritarian rule fuels support for both CPP–NPA and emerging Muslim separatist movements in Mindanao, entrenching armed resistance patterns that continue to shape contemporary conflict dynamics.
The Marcos government and the Moro National Liberation Front sign the Tripoli Agreement, promising autonomy in Muslim-majority areas of Mindanao. Implementation stalls, splintering the Moro movement and setting the stage for later groups, including factions that will eventually ally with Islamic State affiliates.
Mass protests and military defections oust Ferdinand Marcos; Corazon Aquino assumes the presidency. Democratic institutions are restored, but core social and regional inequalities persist, allowing the CPP–NPA insurgency and Moro armed movements to survive and adapt into the conflicts active in the 2000s–2020s.
Following a 1989 law and plebiscite, Manila establishes the Autonomous Region in Muslim Mindanao (ARMM). Limited powers, weak institutions, and uneven development mean many armed groups remain mobilized, creating conditions where later Islamist factions and Islamic State-linked networks can recruit and operate.
The Ramos government and the Moro National Liberation Front sign a final peace deal, integrating many rebels into politics and security forces. However, splinters like the Moro Islamic Liberation Front and Abu Sayyaf continue fighting, leaving Mindanao’s insurgent landscape fragmented and fertile for future jihadist ties.
After 9/11, U.S. forces deploy in Mindanao to support operations against Abu Sayyaf and other militants under the Visiting Forces Agreement. Joint campaigns weaken some groups but do not resolve root causes, as militant networks later evolve and some factions gravitate toward Islamic State.
The government and Moro Islamic Liberation Front sign a landmark peace accord, promising a new autonomous Bangsamoro region. While reducing large-scale separatist war, the deal leaves breakaway factions and jihadist elements active, some later aligning with Islamic State and sustaining Mindanao’s lower-intensity violence.
President Rodrigo Duterte pursues aggressive campaigns against drugs and insurgents, while promising but failing to conclusively end the CPP–NPA conflict. Militarization increases in rural areas and Mindanao, weakening some rebels yet entrenching armed confrontation patterns that carry into the current civil war dynamics.
Maute Group and Abu Sayyaf militants pledging allegiance to Islamic State seize Marawi City, prompting a five-month urban battle. The siege highlights jihadist networks and foreign fighter links, leading to intensified counterinsurgency that still shapes today’s clashes with Islamic State affiliates in Mindanao.
A plebiscite approves the Bangsamoro Autonomous Region in Muslim Mindanao, implementing the 2014 peace accord with the Moro Islamic Liberation Front. While major separatist conflict declines, some factions reject the process, feeding residual jihadist insurgencies that keep Mindanao a hotspot of organized violence.
Ferdinand Marcos Jr. wins the presidency, restoring the Marcos name and tightening security ties with the United States amid South China Sea tensions. While focused on external alignment, his administration maintains military pressure on CPP–NPA and Islamic State-linked groups, sustaining ongoing internal conflicts.
After earlier setbacks, Manila and the CPP announce in November 2023 a roadmap toward possible resumed negotiations, but progress stalls through 2024. Continued fighting, with most fatalities among CPP forces, underscores why the Philippines civil war and Islamist violence both persist above conflict thresholds.
