The Boko Haram insurgency began in July 2009,^[78][79] when the militant Islamist and jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria.^[54][80] The conflict is taking place within the context of long-standing issues of religious violence between Nigeria's Muslim and Christian communities, and the insurgents' ultimate aim is to establish an Islamic state in the region.^[81]

Boko Haram's initial uprising failed, and its leader Mohammed Yusuf was killed by the Nigerian government.^[82] He began the group in the year 2002, with a view of opposing western education with his followers.^[83] The movement consequently fractured into autonomous groups and started an insurgency, though rebel commander Abubakar Shekau managed to achieve a kind of primacy among the insurgents. Though challenged by internal rivals, such as Abu Usmatul al-Ansari's Salafist conservative faction and the Ansaru faction, Shekau became the insurgency's de facto leader and mostly kept the different Boko Haram factions from fighting each other, instead focusing on overthrowing the Nigerian government.^[84] Supported by other jihadist organizations including al-Qaeda and al-Shabaab, Shekau's tactics were marked by extreme brutality and explicit targeting of civilians.^[83]

After years of fighting, the insurgents became increasingly aggressive and began to seize large areas in northeastern Nigeria. The violence escalated dramatically in 2014 with 10,849 deaths, while Boko Haram drastically expanded its territories.^{[85][86][87][88]} At the same time, the insurgency spread to neighboring Cameroon, Chad, Mali, and Niger, thus becoming a major regional conflict in Sub-Saharan Africa.^[52][54][89] Meanwhile, Shekau attempted to improve his international standing among jihadists by tacitly aligning with the Islamic State of Iraq and the Levant in March 2015, with Boko Haram becoming the "Islamic State's West Africa Province" (ISWAP).^[52]

The insurgents were driven back during the 2015 West African offensive by a Nigeria-led coalition of African and Western countries, forcing the Islamists to retreat into Sambisa Forest and bases at Lake Chad.^{[citation needed]} Discontent about various issues consequently grew among Boko Haram. Dissidents among the movement allied themselves with IS' central command and challenged Shekau's leadership, resulting in a violent split of the insurgents. Since then, Shekau and his group are generally referred to as "Boko Haram", whereas the dissidents continued to operate as ISWAP under Abu Musab al-Barnawi. The two factions consequently fought against each other while waging insurgencies against the local governments. After a period of reversals, Boko Haram and ISWAP launched new offensives in 2018 and 2019, again growing in strength.^[90]

When Boko Haram's insurgency was at its peak in the mid-2010s, it was the world's deadliest terrorist organization in terms of the number of people it killed.^[91][92][93] In a bid to ensure dialog between government and the deadly sect, the President Jonathan administration set up a committee to grant an amnesty to Boko Haram.^[94][95] Some details of the amnesty includes granting of pardons to Boko Haram fighters and also listening to different ethnic groups under the sect with a bid to ending violence. This amnesty was rejected by the sect in an audio broadcast that was sent by its leader on the grounds that they are fighting to create an Islamic state in Nigeria's predominantly Muslim north and that it is the government that is committing atrocities against Muslims.^[96]

In May 2021, ISWAP attacked and overran Boko Haram militants in the Sambisa Forest and the leader of Boko Haram Shekau was killed during the fighting, reportedly using a suicide vest.^[97] In August, Abu Musab al-Barnawi, the leading commander of ISWAP, was killed.^[98] After Shekau's death masses of Boko Haram militants surrendered while others defected to ISWAP. According to the Nigerian Defence Forces, as of April 5, 2022, a total of 51,114 rebels and families, consisting of 11,398 men, 15,381 women, and 24,335 children, have surrendered. This number has risen to over 100,000 in July 2023.^[99] A commander of the Joint Task Force expressed optimism that the Boko Haram crisis would end very soon, while advising the troops not to rest or give the terrorists a chance to recuperate, reorganise and start carrying out attacks, saying, “We are almost there, so let’s maintain the momentum.”^[100]

Britain amalgamated both the Northern and Southern protectorate in 1914, about a decade after the defeat of the Sokoto Caliphate and other Islamic states by the British which were to constitute much of Northern Nigeria. Sir Frederick Lugard assumed office as governor of both protectorates in 1912. The aftermath of the First World War saw Germany lose its colonies, one of which was Cameroon, to French, Belgian and British mandates. Cameroon was divided in French and British parts, the latter of which was further subdivided into southern and northern parts. Following a plebiscite in 1961, the Southern Cameroons elected to rejoin French Cameroon, while the Northern Cameroons opted to join Nigeria, a move which added to Nigeria's already large Northern Muslim population.^[101] The territory made up much of what is now Northeastern Nigeria, and a large part of the areas affected by the insurgency.

Religious conflict in Nigeria dates as far back as 1953, and in the case of the town of Tafawa Balewa, to 1948.^[102] The Igbo massacre of 1966 in the North that followed the counter-coup of the same year had as a dual cause the Igbo officers' coup and pre-existing (sectarian) tensions between the Igbos and the local Muslims. This was a major factor in the Biafran secession and the resulting civil war.

In the late 1970s and early 1980s, there was a major Islamic uprising led by Maitatsine (Mohammed Marwa) and his followers, Yan Tatsine that led to several thousand deaths. After Maitatsine's death in 1980, the movement continued some five years more.

In the same decade the erstwhile military ruler of Nigeria, General Ibrahim Babangida enrolled Nigeria in the Organisation of the Islamic Conference. This was a move which aggravated religious tensions in the country, particularly among the Christian community.^[103] In response, some in the Muslim community pointed out that certain other African member states have smaller proportions of Muslims, as well as Nigeria's diplomatic relations with the Holy See.

Since the return of democracy to Nigeria in 1999, Sharia has been instituted as a main body of civil and criminal law in 9 Muslim-majority and in some parts of 3 Muslim-plurality states, when then-Zamfara State governor Ahmad Rufai Sani^[105] began the push for the institution of Sharia at the state level of government. This was followed by controversy as to the would-be legal status of the non-Muslims in the Sharia system. A spate of Muslim-Christian riots soon emerged.

In the primarily Islamic northern states of Nigeria, a variety of Muslim groups and populations exist, who favour the nationwide introduction of Sharia Law.^[106] The demands of these populations have been at least partially upheld by the Nigerian Federal Government in 12 states, firstly in Zamfara State in 1999. The implementation has been widely attributed as being due to the insistence of Zamfara State governor Ahmad Rufai Sani.^[105]

The death sentences of Amina Lawal and Safiya Hussaini attracted international attention to what many saw as the harsh regime of these laws. These sentences were later overturned;^[107] the first execution was carried out in 2002.^[107]

Twelve out of Nigeria's thirty-six states have Sunni Islam as the dominant religion. In 1999, those states chose to have Sharia courts as well as Customary courts.^[108] A Sharia court may treat blasphemy as deserving of several punishments up to, and including, execution.^[109][110] In many predominantly Muslim states, conversion from Islam to another religion is illegal and often a capital offence.^[111]

According to a Nigerian study on demographics and religion, Muslims make up 50.5% of the population. Muslims mainly live in the north of the country; the majority of Nigerian Muslims are Sunnis. Christians are the second-largest religious group and make up 48.2% of the population. They predominate in the central and southern parts of the country.^[112]

For reasons of avoiding political controversy, questions of religion were forgone in the 2006 Nigerian census.^[113][114]

Boko Haram conducted its operations more or less peacefully during the first seven years of its existence.^[115] That changed in 2009 when the Nigerian government launched an investigation into the group's activities following reports that its members were arming themselves.^[116] Prior to that the government reportedly repeatedly ignored warnings about the increasingly militant character of the organisation, including that of a military officer.^[116]

Boko Haram's initial uprising failed, and its leader Mohammed Yusuf was killed by the Nigerian government.^[82] He began the group in the year 2002, with a view of opposing western education with his followers.^[83] He was arrested at his parent inlaws' house by the Nigerian Military and subsequently handed over to the Nigerian police.^[83] He was survived by four wives and 12 children one of which was Abu Musab al-Barnawi who in the year 2016 wanted to lead the group.^[83] The movement consequently fractured into autonomous groups and started an insurgency, though rebel commander Abubakar Shekau managed to achieve a kind of primacy among the insurgents. Though challenged by internal rivals, such as Abu Usmatul al-Ansari's Salafist conservative faction and the Ansaru faction, Shekau became the insurgency's de facto leader and mostly kept the different Boko Haram factions from fighting each other, instead focusing on overthrowing the Nigerian government.^[84] Supported by other jihadist organizations including al-Qaeda and al-Shabaab, Shekau's tactics were marked by extreme brutality and explicit targeting of civilians.^[83]

When the government came into action, several members of the group were arrested in Bauchi, sparking deadly clashes with Nigerian security forces in Bauchi, Maiduguri in Borno State, Potiskum in Yobe State and Wudil in Kano State – which led to the deaths of an estimated 700 people. During the fighting with the security forces Boko Haram fighters reportedly "used fuel-laden motorcycles" and "bows with poison arrows" to attack a police station.^[80] The group's founder and then leader Mohammed Yusuf was also killed during this time while still in police custody.^{[117][118][119]} After Yusuf's killing, Abubakar Shekau became the leader and held this position in January 2015.^[120]

Nearly six months after the killing of Yusuf, the group carried out its first terrorist attack in Borno in January, killing four people.^[121] During the following few years, the violence escalated in terms of both frequency and intensity. On 7 September, a prison break in Bauchi freed more than 700 Boko Haram militants, replenishing their force. On 24 December, Boko Haram used four bombs to kill 32 people in Jos, Plateau State. On the same day, they killed six people in attacks against churches in Maiduguri.

On 29 May, a few hours after Goodluck Jonathan was sworn in as president, several bombings purportedly by Boko Haram killed 15 and injured 55. On 16 June, Boko Haram claimed responsibility for the Abuja police headquarters bombing, the first known suicide attack in Nigeria. Two months later the United Nations building in Abuja was bombed, signifying the first time that Boko Haram attacked an international organisation. On 4 November, it carried out attacks in Damaturu in Yobe and in Maiduguri, killing over a hundred people, and on 22 and 23 December clashing with security forces, resulting in at least 68 deaths. On 25 December, Boko Haram attacked several churches with bombings and shootings.

15 June marked the start of a Federal Government-sanctioned military effort to counter the growing threat of Boko Haram's insurgency. With 21 Armoured Brigade (21 Bde) of the Nigerian Army as its nucleus, Joint Task Force Operation Restore Order (JTF ORO 1) marked the start of the Army's lengthy counter-insurgency (COIN) campaign against Boko Haram. The campaign has gone through several phases and has greatly escalated in scale, capacity, components and stakeholders, since that time.^[122] Results, however, have sometimes been mixed and the Army has been criticised for being too kinetic in its COIN.^{[citation needed]}

In January in Nigeria, Boko Haram attacked Mubi, Yola and Gombi – all in Adamawa State – in addition to Maiduguri and Kano. During the same month, Abubakar Shekau, a former deputy to Yusuf, appeared in a video posted on YouTube. According to Reuters, Shekau took control of the group after Yusuf's death in 2009.^[123] Authorities had previously believed that Shekau died during the 2009 uprising.^[124] By early 2012, the group was responsible for over 900 deaths.^[125] On 8 March, a small Special Boat Service team and the Nigerian Army attempted to rescue two hostages, Briton Chris McManus and Italian Franco Lamolinara, being held in Sokoto, by members of the Boko Haram terrorist organisation loyal to al-Qaeda. Both hostages were killed by their captors before or during the rescue attempt. All the hostage takers were reportedly killed.^[126] On 8 April, at least 38 people were killed by a suicide car bomber in Kaduna. On 24 June, about 40 inmates escaped during a prison break in Damaturu. On 17 June, at least 12 people were killed by three bombings of churches in Kaduna State. On 7 August, 19 people were killed in a mass shooting in Kogi State. On 1–2 November, at least 25 men were killed at the Federal Polytechnic, Mubi. On 25 December, six people were killed in Potiskum and another six in Maiduguri. On 28 December, fifteen people were killed in a village in northeastern Nigeria.

In May, Nigerian government forces launched an offensive in the Borno region in an attempt to dislodge Boko Haram fighters after a state of emergency was called on 14 May. The state of emergency – which was still in force in May 2014 – applied to the states of Borno, Yobe, and Adamawa in northeastern Nigeria.^[127] The offensive had initial success, but the Boko Haram rebels were able to regain their strength.

On 8 February, gunmen killed at least nine polio vaccinators in Kano.^[128] On 18 March, a suicide car bomber rammed a bus in Kano, killing over 20 people. On 16 and 17 April, dozens of civilians were killed during a battle in Baga, Borno, between Boko Haram and the Nigerian Army. On 6 July, Boko Haram massacred 42 students in Yobe,^[129] bringing the school year to an early end in the state. On 5 August, Boko Haram launched dual attacks on Bama and Malam Fatori, leaving 35 dead.^[130] On 11 August, Boko Haram killed 44 people in a mass shooting at a mosque in Konduga, Borno.^[131] On 6 October, the Nigerian Army won a battle against Boko Haram in Damboa, Borno. On 2 November in Borno, gunmen attacked a convoy returning from a wedding, killing over 30 people.

On 15 April, Boko Haram terrorists abducted about 276 teenage female pupils from a secondary school in Chibok in Borno.^[132] The abduction was widely attributed to Boko Haram.^[133] It was reported that the group had taken the girls to neighbouring Cameroon and Chad where they were to be sold into marriages at a price below a dollar each. The abduction of another eight girls was reported later. These kidnappings raised public protests, with some protesters holding placards bearing the Twitter tag #BringBackOurGirls, which had caught international attention.^[134] The Guardian reported that the British Royal Air Force conducted Operation Turus in Nigeria in April in response to the Chibok kidnapping. A source involved with the operation told The Observer that "The girls were located in the first few weeks of the RAF mission", and that "We [RAF] offered to rescue them, but the Nigerian government declined", this was because it viewed any action to be taken as a "national issue", and for it to be resolved by Nigerian intelligence and security services, the source added that the girls were then tracked by the aircraft as they were dispersed into progressively smaller groups over the following months.^[135] Several countries pledged support to the Nigerian government and to help their military with intelligence gathering on the whereabouts of the girls and the operational camps of Boko Haram.

On 13–14 May, Boko Haram ambushed Nigerian soldiers who were searching for the kidnapped girls.

On 20 May, two bombs in the city of Jos, Plateau State, Nigeria, were detonated, killing at least 118 people and injuring more than 56 others. The bombs exploded 30 minutes apart, one at a local marketplace at approximately 3:00 and the second in a parking lot next to a hospital at approximately 3:30, where rescuers responding to the first accident were killed.^[136] Though no group or individual has claimed responsibility, the attacks have been attributed to Boko Haram.^[137]

First responders were unable to reach the scenes of the accidents, as "thousands of people were fleeing the scene in the opposite direction". The bombs had been positioned to kill as many people as possible, regardless of religion, which differed from previous attacks in which non-Muslims were targeted. The bombers were reported to have used a "back-to-back blast" tactic, in which an initial bomb explodes at a central location, and another explodes a short time later with intent to kill people working to rescuing the wounded.^[138]

In 2014, Boko Haram militants increased their attacks on cities and towns in northern Nigeria and captured part of the country's northeast. These attacks included bombings in Maiduguri in January, July and November.^{[citation needed]}

The increasing intensity of the insurgency prompted the Nigerian government to launch an offensive, and with the help of Chad, Niger, and Cameroon, they recaptured many areas that were formerly under the control of Boko Haram.^[139][140]

In late 2014, Boko Haram seized control of Bama, Borno, according to the town's residents.^[141] In December, it was reported that "people too elderly to flee Gwoza Local Government Area were being rounded up and taken to two schools where the militants opened fire on them." Over 50 elderly people in Bama were killed.^[142] A "gory" video was released of insurgents shooting over a hundred civilians in a school dormitory in the town of Bama.^[143]

Between 3 and 7 January, Boko Haram attacked the town of Baga and killed up to 2,000 people,^[144] perhaps the largest massacre by Boko Haram.^[145]

On 10 January, 19 people were killed in a suicide bombing at a market in Maiduguri.^[146] The city is at the heart of the Boko Haram insurgency.^[147] On 12 January, Boko Haram carried out an unsuccessful attack on a Cameroonian Army base.

On 23 January, a coalition of military forces from Nigeria, Chad, Cameroon, and Niger began a counter-insurgency campaign against Boko Haram.^[148] In the early hours of 25 January, Boko Haram launched a major assault on the city.^[149] On 26 January, CNN reported that the attack on Maiduguri by "hundreds of gunmen" had been repelled, but the nearby town of Monguno was captured by Boko Haram.^[150] The Nigerian Army said they repelled another attack on Maiduguri on 31 January.^[151]

On 4 February, the Chad Army killed over 200 Boko Haram militants.^[152] On 4 and 5 February, Boko Haram carried out a massacre in Fotokol, Far North Region, Cameroon, killing 81 civilians, 13 Chadian soldiers and 6 Cameroonian soldiers.^[153] On 6 February, Boko Haram attacked Bosso and Diffa in Niger. On 15 February, a suicide bombing occurred in Damaturu. On 17 February, the Nigerian military retook Monguno in a coordinated air and ground assault.^[154] On 22 February, a suicide bombing occurred in Potiskum. On 24 February, suicide bombings occurred in Potiskum and Kano. On 2 March, the Nigerian Armed Forces defeated Boko Haram in the Battle of Konduga.

On 7 March, Boko Haram's leader Abubakar Shekau pledged allegiance to the Islamic State of Iraq and the Levant (ISIL) via an audio message posted on the organisation's Twitter account.^{[36][155][156]} Nigerian Army spokesperson Sami Usman Kukasheka said the pledge was a sign of weakness and that Shekau was like a "drowning man".^[157] That same day, five suicide bomb blasts left 54 dead and 143 wounded.^[158] On 12 March, ISIL's spokesman Abu Mohammad al-Adnani released an audiotape in which he welcomed the pledge of allegiance, and described it as an expansion of the group's caliphate to West Africa.^[159]

Following its declaration of loyalty to ISIL, Boko Haram was designated as the group's "West Africa Province" (Islamic State West Africa Province, or ISWAP) while Shekau was appointed as its first vali (governor). Furthermore, ISIL started to support Boko Haram, but also began to interfere in its internal matters. For example, ISIL's central leadership attempted to reduce Boko Haram's brutality toward civilians and internal critics, as Shekau's ideology was "too extreme even for the Islamic State".^[35]

On 24 March, residents of Damasak, Borno, said that Boko Haram had taken more than 400 women and children from the town as they fled from coalition forces who retook the area and found a mass grave of Boko Haram victims.^[160] On 27 March, the Nigerian army captured Gwoza, which was believed to be the location of Boko Haram headquarters.^[161] On election day, 28 March, Boko Haram extremists killed 41 people, including a legislator, to discourage hundreds from voting.^[162]

In March, Boko Haram lost control of the Borno towns of Bama^[163] and Gwoza (believed to be their headquarters)^[164] to the Nigerian Army. The Nigerian authorities said that they had taken back 11 of the 14 districts previously controlled by Boko Haram.^[163] In April, four Boko Haram camps in the Sambisa Forest were overrun by the Nigerian military who freed nearly 300 females.^[165] Boko Haram forces were believed to have retreated to the Mandara Mountains, along the Cameroon–Nigeria border.^[166] On 16 March, the Nigerian Army said that it had recaptured Bama.^[167] On 27 March, the day before the Nigerian presidential election, the Nigerian Army announced that it had recaptured the town of Gwoza from Boko Haram.^[168]

By April, the Nigerian military was reported to have retaken most of the areas previously controlled by Boko Haram in Northeastern Nigeria, except for Sambisa Forest in Borno.^[169]

In May, the Nigerian military announced that they had released about 700 women from camps in Sambisa Forest.^[170][171]

On 12 July, two female suicide bombers wearing burqas killed 13 people in Fotokol. In response, the governor of Cameroon's Far North banned the Islamic veil and burqa.

In August, it was reported that over a thousand deaths had occurred since the inauguration of the new administration.^[172]

On 10 October, suicide bombers attacked a market and refugee camp in Baga Sola, Lac, Chad.

On 28 October, it was announced that Nigerian troops had rescued 338 people from Boko Haram near the group's Sambisa Forest stronghold. Of those rescued, 192 were children and 138 were women.^[173]

In December, Muhammadu Buhari, the President of Nigeria, claimed that Boko Haram was "technically defeated"^[91] and it was reported that 1,000 women had been rescued from Boko Haram in January 2016.^[174][175] On 5 December, four female suicide bombers attacked a market on the Chadian side of Lake Chad. On 28 December, female suicide bombers killed over 55 people in Madagali in Adamawa and Maiduguri.^[176][177]

In early October 2015, the United States military deployed 300 troops to Cameroon, with the approval of the Cameroonian government, with the primary mission of providing intelligence support to local forces and conducting reconnaissance flights.^[14][15]

The troops also oversaw a program to transfer American military vehicles to the Cameroonian Army to aid in their fight against Islamist militants.^[178]

As of May 2016, U.S. personnel were involved in drone operations from Garoua, Far North Region, Cameroon, to help provide intelligence in the region to assist local forces. There were additional drone operations based out of Niger.^[179] U.S. Army soldiers in Cameroon are also providing IED awareness training to the country's infantry forces.^[180]

On 25 January, four Boko Haram suicide bombers killed over 30 people in Bodo, Far North, Cameroon.^[181]

On 30 January, at least 86 people were killed by Boko Haram in Dalori, Borno. On 9 February, two young female suicide bombers killed at least 60 people at an internally displaced persons' camp in Dikwa, Borno. On 16 March, two female suicide bombers killed 22 people on the outskirts of Maiduguri.

In March, Boko Haram was reported to have used islands in Lake Chad as bases.^[182]

As Boko Haram's power waned, Shekau's leadership was increasingly criticised among Boko Haram and ISIL's central command. These elements repeatedly attempted to convince Shekau to change his tactics or his extreme ideas (such as considering everyone an apostate who has not openly sided with him, including all Muslims). Shekau refused to budge, and openly disobeyed ISIL's "Caliph" Abu Bakr al-Baghdadi in regard to various matters. ISIL and parts of Boko Haram eventually came to the conclusion that this was no longer tolerable, whereupon Shekau was removed from his position as vali of ISIL's West Africa Province in August. Abu Musab al-Barnawi, a son of Boko Haram founder Mohammed Yusuf was appointed as his successor. This event resulted in an open split among the Nigerian insurgents. Shekau refused to accept his dismissal, rallied a large number of supporters and violently opposed Barnawi and ISIL's central command. In turn, Barnawi and those who were loyal to him declared Shekau's group Khawarij.^[35] The two insurgent factions subsequently became fully separate organizations, with Shekau's followers re-adopting their old name "Jamā'at Ahl as-Sunnah lid-Da'wah wa'l-Jihād" (outsiders refer to this faction as "Boko Haram"), whereas Barnawi's forces continued to operate as "Islamic State's West Africa Province" (ISWAP). The two groups are generally hostile and fight each other, though it is possible that they occasionally cooperate against their common enemies.^[183]

On 31 August, Major General Lucky Irabor stated that the militants now only controlled a few villages and towns near Lake Chad and in Sambisa Forest. He further stated that the military expected recapturing the final strongholds of the group within weeks.^[184]

On 24 December, President Muhammadu Buhari said that Boko Haram had been ousted from their last stronghold in the Sambisa Forest, effectively reducing Boko Haram to an insurgent force.^{[185][186][187]} This victory left Boko Haram without any territorial holdings; however, Boko Haram still maintains an extensive ability to carry out attacks.^[188]

On 7 January, a group of Boko Haram militants attacked a Nigerian Army base in Yobe, killing five soldiers. In response, the Nigerian Army launched retaliatory strikes and killed 15 militants.^[189]

On 17 January, a Nigerian Air Force jet mistakenly bombed an IDP camp near the Cameroonian border in Rann, Borno, mistaking it for a Boko Haram encampment.^{[190][191][192]} The airstrike left 115 people dead.^[193]

On 22 March, at least six people were killed and 16 wounded when four female suicide bombers blew themselves up on the outskirts of Maiduguri city.^[194]

The North consisted of Sahelian states that had long Islamic character. These were feudal and conservative, with rigid caste and class systems and large slave populations.^[303] Furthermore, the North failed until 1936 to outlaw slavery.^[304] Possibly due to geographical factors, many (but not necessarily all) southern tribes, particularly those on the coast, had made contact with Europeans – unlike the North, which was engaged mainly with the Arab world and not Europe. Due to the system of indirect rule, the British were happy to pursue a limited course of engagement with the Emirs.^{[citation needed]} The traditionalist Northern elites were skeptical of Western education;^{[305][306][307]} at the same time their Southern counterparts often sent their sons abroad to study. In time, a considerable developmental and educational gap grew between the South and the North.^[308] Even in 2014, Northern states still lagged behind in literacy, school attendance and educational achievement.^[309]

Chris Kwaja, a Nigerian university lecturer and researcher, asserted in 2011 that "religious dimensions of the conflict have been misconstrued as the primary driver of violence when, in fact, disenfranchisement and inequality are the root causes". Nigeria, he pointed out, has laws giving regional political leaders the power to qualify people as 'indigenes' (original inhabitants) or not. It determines whether citizens can participate in politics, own land, obtain a job, or attend school. The system is abused widely to ensure political support and to exclude others. Muslims have been denied indigene-ship certificates disproportionately often.^[310]

Nigerian opposition leader Buba Galadima said in 2012: "What is really a group engaged in class warfare is being portrayed in government propaganda as terrorists in order to win counter-terrorism assistance from the West."^[311]

The conflict has seen numerous human rights abuses conducted by the Nigerian security forces, in an effort to control the violence,^[312] as well as their encouragement of the formation of numerous vigilante groups (for example, the Civilian Joint Task Force).

Amnesty International accused the Nigerian government of human rights abuses after 950 suspected Boko Harām militants died in detention facilities run by Nigeria's military Joint Task Force in the first half of 2013.^[313] As of early 2016, according to Amnesty International, at least 8,000 detainees have died in detention facilities operated by the security services.^[314] Furthermore, the Nigerian government has been accused of incompetence and supplying misinformation about events in more remote areas.

Boko Haram has kidnapped large numbers of children on several occasions. This has led to Boko Haram members physically, psychologically and sexually abusing them, using and selling them as sex slaves and/or brides of forced marriages with their fighters.^[315] – the most famous example being the Chibok kidnapping in 2014. In addition to kidnapping child brides, Human Rights Watch has stated that Boko Haram uses child soldiers, including 12-year-olds.^[316] According to an anonymous source working on peace talks with the group, up to 40 percent of the fighters in the group are underage soldiers.^[317] The group has forcibly converted non-Muslims to Islam,^[318] and is also known to assign non-Kanuris on suicide missions.^[319]

A major problem faced by local governments is the rehabilitation of captured or surrendered militants, as these are generally suspected by officials and civilians to still hold connections to the rebels and pose a security risk. As result, ex-rebels are often ostracized, which in turn increases the risk of them rejoining the insurgency. Cameroon has planned to construct rehab centers for Boko Haram fighters which are supposed to teach them useful skills to get jobs, and to de-radicalise them. As of February 2019, however, no rehab centers for Boko Haram insurgents had been built yet in Cameroon due to lack of funding.^[320]

The insurgence can be seen in the context of other conflicts nearby, for example in the North of Mali. The Boko Harām leadership has international connections to Al-Qaeda in the Islamic Maghreb, Al-Shabaab, the Movement for Unity and Jihad in West Africa (MUJAO), Mokhtar Belmokhtar's factions, and other militant groups outside Nigeria.^[321] In 2014, Nigerian President, Goodluck Jonathan even went so far as calling Boko Harām "al-Qaeda in West Africa".^[322] By 2012, attacks by Nigerian Islamist militias on targets beyond Nigeria's borders were still limited,^[323] and should not be confused with the activities of other groups (for example, the responsibility of AQIM for most attacks in Niger). Despite this, there were concerns that conflict could spread to Nigeria's neighbours, especially Cameroon, where it existed at a relatively low level until 2014, subsequently escalating considerably. It should also be noted there are combatants from neighboring Chad and Niger.^[324] In 2015, Boko Haram swore allegiance to ISIL.^[36]

On 17 May 2014, the presidents of Benin, Chad, Cameroon, Nigeria and Niger met for a summit in Paris and agreed to combat Boko Harām on a coordinated basis, sharing in particular surveillance and intelligence gathering. Goodluck Jonathan^[325] and Chadian counterpart, Idriss Deby^[3] have both declared total war on Boko Harām. Western nations, including Britain, France, Israel, and the United States had also pledged support including technical expertise and training.^[326][327] The New York Times reported in March 2015 that hundreds of private military contractors from South Africa and other countries are playing a decisive role in Nigeria's military campaign, operating attack helicopters and armored personnel carriers and assisting in the planning of operations.^[10]
