The Moro conflict was an insurgency
in the Mindanao
region of the Philippines
from 1969 to 2019.
In the 1960s, political tensions and open hostilities developed between the Philippine government
and Moro Muslim
The Moro insurgency was triggered by the Jabidah massacre
in 1968, during which 60 Filipino Muslim
commandos on a planned operation to reclaim
the eastern part of the Malaysian state of Sabah
were killed. In response, University of the Philippines
professor Nur Misuari
established the Moro National Liberation Front
(MNLF), an armed insurgent group committed to establishing an independent Mindanao
In the following years, the MNLF splintered into several different groups including the Moro Islamic Liberation Front
(MILF), which sought to establish an Islamic state within the Philippines. The Moro conflict is rooted in a long history of resistance
by the Bangsamoro people against foreign rule, including the American annexation of the Philippines
in 1898; Moro resistance against the Philippine government has persisted ever since.
Casualty statistics vary for the conflict, though the conservative estimates of the Uppsala Conflict Data Program
indicate that at least 6,015 people were killed in armed conflict between the government of the Philippines and the Abu Sayyaf
(ASG), BIFM, MILF, and MNLF factions between 1989 and 2012.
The Moro people
have had a history of resistance against foreign rule for more than 400 years. During the Spanish–Moro conflict
, Spain repeatedly tried to conquer the Moro Sultanate of Sulu
, Sultanate of Maguindanao
, and the Confederation of sultanates in Lanao
. The armed struggle against the Spanish, Americans, Japanese, and Christian Filipinos is considered by current Moro Muslim leaders to be part of a four-century-long "national liberation movement" of the Bangsamoro (Moro Nation).
The foundations of the modern conflict can be traced to the Spanish and American wars against the Moros. Following the Spanish–American War
in 1898, another conflict sparked in the southern Philippines between the revolutionary Muslims in the Philippines
and the United States military
that took place between 1899 and 1913. On August 14, 1898, after defeating Spanish forces, the United States claimed the Philippines as its territory under the Treaty of Paris of 1898
, establishing a military government under General Wesley Merritt
as Military Governor
. Filipinos immediately opposed foreign rule by the United States.
American forces took control from the Spanish government in Jolo
on May 18, 1899, and at Zamboanga
in December 1899. Brigadier General John C. Bates
was sent to negotiate a treaty with the Sultan of Sulu
, Jamalul Kiram II. Kiram was disappointed by the American takeover, as he expected to regain sovereignty after the defeat of Spanish forces in the archipelago. Bates' main goal was to guarantee Moro neutrality in the Philippine–American War
, and to establish order in the southern Philippines. After some negotiation, the Bates Treaty was signed, which was based on an earlier Spanish treaty. The Bates Treaty did ensure the neutrality of the Muslims in the south, but it was actually set up to buy time for the Americans until the war in the north ended. On March 20, 1900, Bates was replaced by Brigadier General William August Kobbé
and the District of Mindanao-Jolo was upgraded to a full department. American forces in Mindanao were reinforced and hostilities with the Moro people lessened, although there are accounts of Americans and other civilians being attacked and slain by Moros.
The American invasion began in 1904 and ended at the term of Major General John J. Pershing
, the third and final military governor of Moro Province, although major resistance continued in Mount Bagsak
and Bud Dajo
; in the latter, the United States military killed hundreds of Moro in the Moro Crater massacre
. After the war, in 1915, the Americans imposed the Carpenter Treaty on Sulu.
Repeated rebellions by the Moros against American rule continued to break out even after the main Moro Rebellion ended, right up to the Japanese occupation of the Philippines
during World War II
. During the Japanese invasion, the Moros waged an insurgency against the Japanese
on Mindanao and Sulu until Japan surrendered in 1945. Moro Juramentado
s attacked the Spanish, Americans, Philippine Constabulary
, and the Japanese.
colonial government and subsequently the Philippine government
pursued a policy of intra-ethnic migration by resettling significant numbers of Christian Filipino
settlers from the Visayas
onto tracts of land in Mindanao
, beginning in the 1920s. This policy allowed Christian Filipinos to outnumber both the Moro and Lumad
populations by the 1970s, which was a contributing factor in aggravating grievances between the Moro and Filipino Christian settlers as disputes over land increased. Another grievance by the Moro people is the extraction of Mindanao's natural resources by the central government whilst many Moros continued to live in poverty.
Moro Muslims and Lumads were largely supplanted during the Spanish and American colonization programs, with Christian Filipino settlers eventually taking control of key areas along newly built roads and disrupting traditional Moro administrative structures and control over resources. The Americans preferred Christians to become administrators of newly defined townships instead of Lumad and Moro, with environmental degradation resulting from unsustainable population growth (due to the influx of settler migrants) and timber logging.
Under President Ferdinand Marcos
, it was alleged that at least 11 Filipino Muslim military trainees were killed in Corregidor
by soldiers of the Armed Forces of the Philippines
The trainees were believed to be a part of an upcoming rebellion.
By then, University of the Philippines
professor Nur Misuari
had formed the Moro National Liberation Front
(MNLF) to condemn the alleged killings of the 11 Muslims and to seek the establishment of a Bangsamoro nation
through the force of arms.
In 1969, the MNLF was established and commenced an armed struggle against the Philippine government
During one of the fiercest battles of the insurgency in 1974, Jolo
was extensively damaged
and news of the tragedy galvanized other Muslim
s around the world to pay greater attention to the conflict. Many civilians were supposedly killed when the Armed Forces
razed much of Jolo
municipality to the ground in a scorched-earth tactic. On September 24, 1974, the Philippine Army
killed at least 1,000 Moro civilians who were praying in a mosque in what is known as the Malisbong massacre
. Two years later, the Philippine government and the MNLF signed the Tripoli Agreement, declaring a ceasefire on both sides. The agreement provided that Mindanao would remain a part of the Philippines, but that 13 of its provinces would be governed by an autonomous government for the Bangsamoro people
President Marcos later reneged on the agreement, and violence ensued.
The Philippine government allegedly encouraged Christian settlers in Mindanao to form a militia called the Ilaga
to fight the Moros. The Ilaga engaged in killings and human rights abuses and were responsible for the Manili massacre
of 65 Moro Muslim civilians in a mosque in June 1971, including women and children. The Ilaga allegedly also engaged in cannibalism, cutting off the body parts of their victims to eat in rituals.
In 1978, Sheikh Salamat Hashim established the Moro Islamic Liberation Front
(MILF), a splinter group of the MNLF seeking to establish an Islamic state.
Conflicts between these rebel groups and the Armed Forces of the Philippines
continued until the end of President Marcos' regime.
C. Aquino and Ramos (1986–1998)
Earlier in her term, President Corazon Aquino
arranged a meeting with MNLF chairman Nur Misuari and several MNLF rebel groups in Sulu
, which paved the way for a series of negotiations. In 1989, the Autonomous Region in Muslim Mindanao
(ARMM) was created under Republic Act No. 6734 or the ARMM Organic Act, pursuant to the 1987 Constitution
In 1991, Abdurajak Janjalani, a former teacher who had studied Islam
in the Middle East
, formed the Abu Sayyaf Group
after reportedly meeting Osama bin Laden
in the 1980s. Janjalani recruited former members of the MNLF for the more radical and theocratic Abu Sayyaf.
Under the Presidency
of Fidel V. Ramos
, several negotiations and peace talks
were held and the ARMM solidified and was to have its own geopolitical system.
Political map of the Autonomous Region in Muslim Mindanao
During his term, President Joseph Ejercito Estrada
declared an "all-out war" against the MILF
on March 21, 2000, although a series of negotiations for cessation of hostilities were held.
Apparently, several conflicts in and around Mindanao erupted and clashes between the Philippine military
and the rebel groups resulted in substantial loss of life.
During Estrada's term, the rebel groups kidnapped three Italian
priests, two of whom were later released and one shot dead;
seized the municipal hall of Talayan
, and Kauswagan
, Lanao del Norte
; bombed the RORO ferry M/V ''Our Lady of Mediatrix'' at Ozamiz
; and took over Narciso Ramos Highway. All these incidents resulted in massive loss of investments abroad, especially in the area of Mindanao.
As a result, the Armed Forces of the Philippines
launched a successful campaign against the rebel groups; 43 minor camps, 13 major camps including the MILF headquarters, and Camp Abubakar
fell. The MILF suffered heavy losses and the head of the MILF, Sheikh Salamat Hashim, fled the country and sought refuge in Malaysia
. On October 5, 2000, 609 rebels surrendered in Cagayan de Oro
, along with renegade town mayor Mulapandi Cosain Sarip. This was followed by another surrender of 855 rebels on December 29, 2000. President Estrada then ordered that the Philippine flag
be raised in Mindanao, which symbolized victory. It was raised on July 9, 2000, near a Madh'hab
and again the next day for President Estrada, who held a feast inside a classroom just meters away from a mosque.
As a result, several Islamic rebel groups retaliated, bombing several key locations
within the National Capital Region
on December 30, 2000, resulting in 22 deaths and hundreds of people injured. Saifullah Yunos, one of the perpetrators, was arrested in Cagayan de Oro
as he was about to board a plane bound for Manila in May 2003.
In 2004, two members of the Jemaah Islamiyah
were arrested, namely Mamasao Naga and Abdul Pata, as they were identified by Fathur Rahman al-Ghozi
as responsible for the train bombing.
Al-Ghozi was also arrested, but was later killed in a firefight when he tried to escape from prison on October 13, 2003.
Macapagal Arroyo (2001–2010)
On May 27, 2001, the Abu Sayyaf seized twenty hostages
from an upscale resort in Palawan
. Four of the hostages managed to escape.
The kidnapping group composed of 40 gunmen then seized the Dr. Jose Torres Memorial Hospital and St. Peter's Church compound in the town of Lamitan
and claimed to have taken captive 200 people, although 20 people were confirmed to be taken captive inside the hospital, including the staff and the patients.
There was a crossfire between the Philippine Army and Abu Sayyaf
rebels in Lamitan
following the hospital takeover which resulted in the deaths of 12 soldiers, including the army captain.
Up to 22 soldiers were reportedly killed in an effort to rescue the hostages.
Five more captives escaped during the battle at Lamitan. Two of the captives were killed prior to the siege in Lamitan, including one beheading.
The Abu Sayyaf then conducted a series of raids
, including one at a coconut plantation
where the rebel groups hacked the heads of two men using bolo knives
. The owners and a security guard were also held captive and the rebel groups burned down two buildings, including a chapel
, a week after the battle in Lamitan
Another raid was conducted on August 2, 2001 on Barangay Balobo in Lamitan
. After three days, the Philippine Army rescued numerous hostages
after they overtook the hideout of the militants, where 11 bodies were found beheaded. Other hostages were either released or had escaped.
On June 13, 2001, the number of hostages was calculated at around 28, as three more people were found beheaded in Basilan
including Guillermo Sobero.
They were beheaded since the Philippine Army would not halt the rescue operation.
The Burnhams were still in the group of 14 still held captive, according to three hostages who escaped in October 2001.
On June 7, 2002, after a year of the hostages being held captive, a rescue mission was conducted resulting in the deaths of Martin Burnham and a nurse named Ediborah Yap
after they were caught in the crossfire. Martin was killed by three gunshots to the chest while Gracia Burnham was wounded in her right leg. By this time Nur Misuari ordered his supporters to attack government targets to prevent the holding of elections
on ARMM in November 2001, ushering his exit as the governor of the region.
Misuari would be later arrested in 2007 in Malaysia
and was deported back to the Philippines for trial.
In July 2004, Gracia Burnham testified at a trial of eight Abu Sayyaf members, identifying six of the suspects as being her former captors, including Alhamzer Limbong, Abdul Azan Diamla, Abu Khari Moctar, Bas Ishmael, Alzen Jandul and Dazid Baize. Fourteen Abu Sayyaf members were sentenced to life imprisonment
while four were acquitted
. Alhamzer Limbong was later killed in a prison uprising
These rebel groups, especially the Abu Sayyaf
, conducted several terror attacks, namely the bombings at Zamboanga
in October 2002; the bombing of SuperFerry 14
in February 2004; the simultaneous bombings in Central Mindanao
in October 2006; the beheadings of several Philippine Marines
in July 2007; the Batasang Pambansa bombing
in November 2007; and the 2009 bombings in Mindanao
One thousand MILF
rebels under the command of Umbra Kato
have seized control of thirty-five villages in the North Cotabato
province. Two thousand Philippine troops with helicopters and artillery were sent into the seized area on August 9 to liberate it from the rebels. The MILF had wanted North Cotabato to be included in the Autonomous Region in Muslim Mindanao
. The government and MILF had been negotiating for the inclusion of the province in the Muslim Autonomous Region but the Supreme Court
had struck down the proposal after hearing concerns from local Christian leaders in the region.
The rebel troops were ordered to leave the area by their commanders, but the contingents under Kato refused to leave the villages they had occupied and instead dug in. The Philippine Army responded on August 9 by bombarding them. The next day, the government forces moved to retake the villages, recapturing two of them from the rebels.
Numerous clashes erupted between the Philippine Army and rebel groups, such as the clash on June 14, 2009 that killed 10 rebels.
Between 2002 and 2015, the Philippines and the United States
were part of a joint military campaign against Islamist terrorism known as Operation Enduring Freedom – Philippines
. This was part of the War on Terror
Benigno Aquino (2010–2016)
In 2013, two main camps of the Abu Sayyaf group were overrun by forces of the Moro National Liberation Front
(MNLF) in its latest offensive in Patikul
. According to MNLF leader Nur Misuari, the MNLF offensive against the Abu Sayyaf is because of the MNLF opposition to the Abu Sayyaf's human rights abuses, which go against Islam
During the term of President Benigno Aquino III
, a series of peace talks for the cessation of hostilities was held, including the meeting of MILF
Chair Al Haj Murad Ibrahim in Tokyo
which was lauded on both sides.
also joined the International Monitoring Team
(IMT) in January 2011, overseeing the ceasefire agreement between the government and MILF on Mindanao
. Despite the peace talks, a series of conflicts erupted. On September 10, 2011, Jal Idris, a hardcore member of Abu Sayyaf, was arrested by government forces after a crossfire between the Philippine Army
and the rebel group The Armed Forces of the Philippines
also killed three Abu Sayyaf militants in a stand-off the day after the arrest of Jal Idris.
Terrorism continued throughout President Aquino's term. Notable cases include when four merchants and a guide were killed by Abu Sayyaf bandits in January 2011. Later a soldier was killed in a clash against the rebels. In August 2011, rebel factions attacked a village in Sulu
, killing seven Marines and taking seven civilians captive. They later freed two of the hostages after a ransom was paid. Also, several areas of Mindanao were bombed in August by the government, and a Filipino businesswoman was abducted in September 2011, who was later freed after the three gunmen were gunned down by the Armed Forces of the Philippines
On October 20, 2011, the MILF was blamed for an attack on 40 government soldiers in the province of Basilan
, which led to the deaths of 19 soldiers and six MILF fighters. This violated the ceasefire agreement between the government and MILF, which caused outrage in the government and led to the continuation of the war against terrorism in the country
The Zamboanga City crisis
erupted on September 9, 2013, when a MNLF faction known by other groups as the Rogue MNLF Elements (RME), under the Sulu State Revolutionary Command (SSRC), led by Ustadz Habier Malik and Khaid Ajibon attempted to raise the flag of the self-proclaimed Bangsamoro Republik
at Zamboanga City
Hall (which had earlier declared its independence on August 12, 2013 in Talipao, Sulu), and took civilians hostage. This armed incursion was met by the Armed Forces of the Philippines (AFP) and the Philippine National Police (PNP), which sought to free the hostages and expel the MNLF from the city. The standoff degenerated into urban warfare, and had brought parts of the city under a standstill for days. On September 28, the government declared the end of military operations in Zamboanga City after successfully defeating the MNLF and rescuing all the hostages.
On January 24, 2014, the Philippines government chief negotiator Miriam Coronel-Ferrer
and MILF chief negotiator Murad Ebrahim
signed a peace agreement in Kuala Lumpur
. The agreement would pave the way for the creation of the new Muslim autonomous entity called "Bangsamoro" under a law to be approved by the Philippine Congress. The government aims to set up the region by 2016. The agreement calls for Muslim self-rule in parts of the southern Philippines in exchange for a deactivation of rebel forces by the MILF. MILF forces would turn over their firearms to a third party to be selected by the MILF and the Philippine government. A regional police force would be established, and the Philippine military would reduce the presence of troops and help disband private armies in the area. On March 27, 2014, the peace process concluded with the signing of the Comprehensive Agreement on the Bangsamoro
between the Government of the Philippines
and the Moro Islamic Liberation Front
''The New York Times
'' claimed that the peace deal between the Philippines and MILF
"seeks to bring prosperity to the restive south and weaken the appeal of the extremist groups", and linked the winding down of an American military counterterrorism operation
to increased American military cooperation with the Philippines against China. ''The New York Times'' hailed Mr Aquino's peace agreement as an "accomplishment" as it reported on Aquino raising the alarm on China in the South China Sea. ''The New York Times'' editorial board published an article siding with the Philippines against China in the South China Sea dispute and supporting the Philippines' actions against China. ''The New York Times'' editorial board endorsed aggressive American military action against China in the South China Sea.
On July 23, 2014, Abu Sayyaf
leader Isnilon Hapilon swore loyalty to Abu Bakr al-Baghdadi
in a video, along with the rest of the organization, giving ISIL a presence in the Philippines.
In September 2014, the group began kidnapping people to ransom, in the name of ISIL.
On January 25, 2015, the Philippine National Police's Special Action Force
(SAF) conducted an operation
to capture Abdul Basit Usman
in Mamasapano, Maguindanao
. They were trapped between the MILF
's 105th Base Command, the BIFF, and several armed groups. Forty four SAF members were killed on what is known as the Mamasapano clash
, but they were able to eliminate Marwan. Alleged United States involvement in the botched operation would likely be a setback for a so-called Asian "pivot" by the United States Armed Forces
In February 2015, the BIFF unsuccessfully fought for territory in the boundary of Maguindanao
and North Cotabato
provinces. Subsequently, the Philippine Army, along with the Philippine Marines, declared a state of all-out-war against the BIFF. MILF forces were pulled out to prevent them from falling victim to the fighting.
Rodrigo Duterte (2016–present)
The MILF and MNLF have expressed their commitment to peace and in finally ending the 47-year-old insurgency while the offensive against Abu Sayyaf and other splinter groups have continued, with skirmishes in Jolo
and other parts of Mindanao. A bombing in Davao City
in September 2016 killed 15 people. Elsewhere, on May 23, 2017, the Maute group attacked Marawi
. President Rodrigo Duterte
declared Proclamation No. 216
, which placed the whole of Mindanao under a state of martial law
and suspended the writ of habeas corpus
. Clashes continued until October 2017 as the battle for Marawi City pitted Islamic militants against the Philippine government forces. Violence was severe. The government used heavy artillery and air strikes to shell Abu Sayyaf and Maute positions while the militant groups resorted to executing captured Christians.
In 2018, two bombing incidents involving Abu Sayyaf and the BIFF
