Timeline of the Moro conflict

Overview

The Moro conflict represents a protracted, low-intensity struggle in the southern Philippines, characterized by complex dynamics between various armed factions and the central state. This chronology documents a conflict involving jihadist organizations such as the Abu Sayyaf Group, the Maute Group, Jemaah Islamiyah, and affiliates of the Islamic State. Simultaneously, it encompasses mainstream separatist movements, including the Moro Islamic Liberation Front (MILF), the Moro National Liberation Front (MNLF), and the Bangsamoro Islamic Freedom Fighters (BIFF), in opposition to the Philippine Government. The conflict has been active since 1971, marking decades of intermittent and sustained hostilities.

Geographically, the fighting has been heavily concentrated on the island of Mindanao and the Sulu archipelago. These regions have served as the primary theaters for both conventional battles and guerrilla warfare. However, the conflict’s reach extends beyond these immediate locales. Spillover incidents and targeted attacks have occurred in the Philippine capital, Manila, as well as in neighboring countries, notably Malaysia. This geographical spread highlights the transnational and urban dimensions of the struggle, affecting stability across multiple administrative and national boundaries.

As of 2019, the nature of the conflict underwent a significant shift. The direct conflict between the major separatist groups and the Philippine Government largely concluded, following years of peace negotiations and the establishment of the Bangsamoro Autonomous Region in Muslim Mindanao. Despite this political milestone, the insurgency led by Islamic State affiliates continues to pose a security challenge. This ongoing jihadist presence indicates that while the primary separatist dispute has been largely resolved, the broader security landscape in the southern Philippines remains dynamic and complex.

Origins and Early Insurgency (1968–1975)

The Moro conflict, an active low-intensity war in Mindanao, traces its institutional origins to 1968. The Philippine Government has been the primary governing body opposing various separatist and jihadist factions since the insurgency began. The conflict involves mainstream groups like the Moro National Liberation Front (MNLF) and Moro Islamic Liberation Front (MILF), alongside jihadist affiliates such as the Abu Sayyaf Group and Maute Group. Much of the fighting has concentrated on the island of Mindanao and the Sulu archipelago, with spillover incidents reaching Manila and neighboring Malaysia.

Founding and Early Triggers (1968–1971)

In 1968, Datu Udtog Matalam founded the Muslim Independence Movement (MIM), marking the first organized political push for Moro autonomy. The following year, 1969, saw the founding of the MNLF by Nur Misuari. This formation was heavily influenced by the Jabidah massacre, which galvanized Muslim political consciousness. Tensions escalated into armed confrontation in 1971 with the Ilagas massacre, signaling the shift from political maneuvering to open insurgency.

Martial Law and Escalation (1972–1975)

Ferdinand Marcos imposed martial law in 1972, which triggered a widespread armed Muslim insurgency. Major battles erupted in 1972, including the conflicts at Sibalo Hill and Jolo. The military pressure forced MNLF leadership to flee abroad to consolidate support. In 1974, insurgents launched attacks on strategic infrastructure, targeting Maria Cristina Falls and Cotabato. The violence intensified in 1975 with massacres in Zamboanga and Sulu, cementing the region's status as a primary theater of war.

Escalation and Fragmentation (1976–1990)

The period from 1976 to 1990 marked a critical phase of escalation and fragmentation in the Moro conflict. Following the initial outbreak of hostilities, casualty estimates for 1976 indicated significant loss of life, though precise figures varied across reports. The conflict involved jihadist groups such as the Abu Sayyaf Group and the Maute Group, as well as mainstream separatist entities including the Moro National Liberation Front (MNLF) and the Moro Islamic Liberation Front (MILF).

Failed Peace Talks and Leadership Split

Peace negotiations between the Philippine Government and the MNLF during 1976 and 1977 ultimately failed to secure a lasting truce. This diplomatic stalemate exacerbated internal divisions within the separatist movement. In 1978, a significant split occurred in the MNLF leadership between Salamat Hashim and Nur Misuari. This fracture was driven by disagreements over the terms of peace agreements and the strategic direction of the movement.

Establishment of the MILF and Continued Violence

Following the leadership split, Salamat Hashim established the Moro Islamic Liberation Front (MILF) in 1984. The MILF emerged as a more Islamist-oriented faction compared to the secular MNLF. Throughout the 1980s, violence persisted across Mindanao and the Sulu archipelago. Notable incidents included massacres in 1980 and intense clashes in 1987. The conflict also saw spillover attacks in Manila and neighboring Malaysia.

Rise of Jihadist Groups and Kidnapping (1991–2000)

The 1990s marked a critical escalation in the Moro conflict, characterized by the emergence of jihadist factions and the institutionalization of kidnapping as a strategic tool. While the broader conflict involved mainstream separatist groups like the Moro National Liberation Front (MNLF) and the Moro Islamic Liberation Front (MILF), this period saw the rise of the Abu Sayyaf Group (ASG), founded by Abdurajak Janjalani in 1991. The ASG introduced a more radical, jihadist ideology to the southern Philippines, distinct from the secular or Islamic political goals of the MNLF and MILF. This era also witnessed significant spillover of violence, with attacks occurring not only in Mindanao and the Sulu archipelago but also reaching the Philippine capital, Manila, and neighboring Malaysia.

Emergence of Abu Sayyaf and Kidnapping Trends

The strategic use of kidnapping for ransom began to take shape in the region around 1990, with early trends attributed to figures such as Abogado Gado. This tactic would later become a hallmark of the Abu Sayyaf Group, funding their operations and projecting power across the Sulu Archipelago. The group's radicalization led to targeted violence against various communities, including Christians, and prompted sustained military offensives by the Philippine Government throughout the late 1990s.

Political Developments and Continued Violence

Amidst the rising jihadist threat, diplomatic efforts yielded partial successes. A significant peace agreement in 1996 facilitated the entry of the MNLF into formal politics, offering a potential pathway to stability. However, the death of Abdurajak Janjalani in 1998 did not immediately quell the ASG's momentum. The years 1999 and 2000 were marked by continued volatility, with the ASG launching attacks on Christian populations, including incidents in mosques, while the Philippine military conducted sustained offensives to contain the group's expansion in the Sulu Archipelago and Mindanao.

Intensified Military Operations (2001–2015)

Military operations against Moro separatist and jihadist factions intensified significantly between 2001 and 2015, marked by high-profile engagements and strategic shifts in alliance structures. During this period, the Philippine Government continued its campaign against groups including the Abu Sayyaf Group (ASG), the Moro Islamic Liberation Front (MILF), and the Moro National Liberation Front (MNLF), primarily across Mindanao and the Sulu archipelago.

Key Engagements and Casualties

Notable military encounters defined this era. In 2003, Mujib Susukan was killed during operations, highlighting the persistent threat posed by local commanders. The following year, a significant gunbattle involved Lieutenant Colonel Noel Buan and Hamsiraji Sali, underscoring the intensity of ground combat in key territories. These engagements contributed to the broader pattern of violence that characterized the conflict's second decade.

Abu Sayyaf Group Activities

The Abu Sayyaf Group remained a primary target of military and police forces. In 2006, the ASG executed a series of bomb attacks, demonstrating their continued capability to project power through asymmetric warfare. These incidents occurred alongside spillover attacks in Manila and neighboring regions, illustrating the conflict's expanding geographic footprint beyond Mindanao.

Strategic Shifts: MNLF and MILF

A major political-military development occurred in 2012, when the MNLF formally defected to the MILF. This consolidation of separatist forces altered the diplomatic and military landscape, as the Philippine Government adjusted its negotiation strategies and operational focus. The merger reflected internal dynamics within the Moro movement and aimed to strengthen bargaining power in peace talks.

Timeline of Key Events (2001–2015)

Since the 1990s, the conflict has resulted in substantial casualties and displacement, affecting communities across Mindanao and the Sulu archipelago. The Philippine Government's military strategy during this period focused on containing jihadist expansion while pursuing negotiated settlements with mainstream separatist groups. The interplay between kinetic operations and diplomatic efforts defined the conflict's trajectory from 2001 to 2015.

The Marawi Siege and ISIS Expansion (2016–2019)

The period from 2016 to 2019 marked a significant escalation in the Moro conflict, characterized by the emergence of jihadist factions and intense urban warfare. The Maute Group, an affiliate of the Islamic State, initiated major clashes in late 2016, leading to the protracted Siege of Marawi. This conflict involved jihadist groups such as the Abu Sayyaf Group, the Maute Group, Jemaah Islamiyah, and Islamic State affiliates, alongside mainstream separatist groups like the Moro Islamic Liberation Front (MILF), the Moro National Liberation Front (MNLF), and the Bangsamoro Islamic Freedom Fighters (BIFF). Much of the fighting was concentrated on the island of Mindanao and the Sulu archipelago, with spillover incidents occurring in Manila and neighboring countries such as Malaysia.

Key Events (2016–2019)

In 2017, the conflict saw multiple significant engagements. The Kidapawan jail siege occurred, testing the capacity of local and national forces. Simultaneously, the Abu Sayyaf Group launched attacks, including clashes in Bohol. The leadership of the jihadist factions was decimated in 2017 with the deaths of Isnilon Hapilon and Omar Maute. The Siege of Marawi concluded in October 2017, marking a temporary shift in the tactical landscape. In 2018, the Bangsamoro Islamic Freedom Fighters (BIFF) intensified their campaign with a series of attacks and bombings. The violence persisted into 2019, highlighted by the Jolo Cathedral suicide bombing carried out by Islamic State affiliates. These events underscored the complex dynamics involving the Philippine Government and various separatist and jihadist entities in Mindanao.

Recent Developments and Current Status (2020–2026)

The conflict entered a phase of intensified counter-insurgency operations between 2020 and 2026, focusing on the fragmentation of jihadist affiliates. During 2020, sustained military pressure resulted in significant casualties among the Abu Sayyaf Group (ASG) and the Bangsamoro Islamic Freedom Fighters (BIFF) across Mindanao and the Sulu archipelago. In 2021, security forces targeted ASG sub-leaders in a series of encounters designed to disrupt command structures.

Operations Against Dawlah Islamiya and BIFF

From 2022 to 2023, operations expanded to target Dawlah Islamiya (DI) and BIFF strongholds. The security landscape shifted significantly following the 2023 MSU Marawi bombing. This incident triggered a subsequent manhunt that mobilized multiple branches of the Armed Forces of the Philippines (AFP) to secure the Lanao del Sur capital and surrounding areas. The bombing highlighted the persistent threat of Islamic State affiliates operating within urban centers previously considered stabilized.

Leadership Decapitation and Remnants (2024–2026)

Between 2024 and 2025, military campaigns focused on the killings of DI-MG leaders, aiming to decapitate the joint command structure of Dawlah Islamiya and the Maute Group remnants. By 2026, operations continued against DI-MG remnants, targeting scattered cells in the southern provinces. In 2025, the AFP announced a measurable decrease in Local Terrorist Group (LTG) members, citing improved intelligence and kinetic operations. Despite these gains, the conflict remains active, with spillover incidents continuing to affect regional stability.

What distinguishes the Moro conflict from other Philippine insurgencies?

The Moro conflict is distinguished from other Philippine insurgencies by its complex multi-actor structure, combining mainstream separatist movements with distinct jihadist factions. The conflict involves groups such as the Moro National Liberation Front (MNLF), the Moro Islamic Liberation Front (MILF), and the Bangsamoro Islamic Freedom Fighters (BIFF), alongside jihadist organizations including the Abu Sayyaf Group, the Maute Group, Jemaah Islamiyah, and Islamic State affiliates. This diversity of actors creates a layered struggle that differs significantly from singular ideological uprisings, as it encompasses both political autonomy demands and religious militancy.

Geographically, the conflict is heavily concentrated on the island of Mindanao and the Sulu archipelago. This regional focus contrasts with other insurgencies that may have been more dispersed or centered on different islands. The concentration in these southern regions has defined the strategic and logistical landscape of the war. However, the conflict is not entirely contained within these borders. Spillover incidents and attacks have occurred in the Philippine capital, Manila, as well as in neighboring countries such as Malaysia. This transnational and urban spillover demonstrates the reach of the conflict beyond its primary geographic heartland.

The nature of the conflict has evolved over time. While the struggle has involved the Philippine Government since 1971, the character of the fighting has shifted. There has been a notable transition from a primary focus on separatist politics to an increased emphasis on jihadist dynamics, particularly in the post-2019 period. This shift reflects the changing alliances and strategic priorities of the various groups involved. The ongoing status of the conflict, which began in 1968, indicates that these dynamics remain active and continue to shape the political and security landscape of the southern Philippines.

How have peace agreements impacted the conflict?

The trajectory of the Moro conflict has been significantly shaped by major peace agreements, though these accords have produced a fragmented political and military landscape rather than a singular resolution. The 1996 General Ceasefire Agreement between the Philippine Government and the Moro National Liberation Front (MNLF) marked a critical turning point, transitioning the MNLF from a primary armed separatist force into a key political actor in Mindanao. This agreement facilitated the creation of the Autonomous Region in Muslim Mindanao (ARMM), allowing the MNLF to leverage political influence and administrative control, thereby altering the dynamics of regional governance and reducing direct military confrontation for this specific faction.

Parallel to the MNLF's political integration, the conflict with the Moro Islamic Liberation Front (MILF) concluded with the ratification of the Bangsamoro Organic Law in 2019. This landmark agreement effectively ended the longest-running armed struggle between the Philippine state and a mainstream separatist group, replacing the ARMM with the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM). The establishment of the BARMM represented a comprehensive political settlement, addressing core grievances regarding self-governance, resource sharing, and identity for the broader Moro population.

Despite these significant diplomatic successes, the conflict has not been entirely extinguished. The peace processes primarily addressed mainstream separatist movements, leaving jihadist and insurgent factions active. Groups such as the Abu Sayyaf Group, the Maute Group, and various Islamic State affiliates have continued to wage a low-level war, characterized by raids, sieges, and urban spillover incidents. This has resulted in a fragmented post-conflict environment where political stability in BARMM coexists with persistent military engagements against Islamist insurgents. The continuation of these insurgencies demonstrates that while the primary separatist dispute has been largely resolved, security challenges remain complex, requiring ongoing military and political strategies to address the diverse motivations of remaining armed groups in Mindanao and the Sulu archipelago.
