The Boko Haram insurgency began in 2009, when the jihadist group Boko Haram started an armed rebellion against the government of Nigeria. The conflict takes 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.

Starting in late January 2015, a coalition of West African troops launched an offensive against the Boko Haram insurgents in Nigeria.

The Islamic State in West Africa or the Islamic State's West Africa Province, formerly known as Jamā'at Ahl as-Sunnah lid-Da'wah wa'l-Jihād and commonly known as Boko Haram, is a jihadist terrorist organization based in northeastern Nigeria, also active in Chad, Niger and northern Cameroon.

The Chad Basin campaign of 2018–2020 was a series of battles and offensives in the southern Chad Basin, particularly northeastern Nigeria, which took place amid the ongoing Boko Haram insurgency. The Chad Basin witnessed an upsurge of insurgent activity from early November 2018, as rebels belonging to the Islamic State's West Africa Province (ISWAP) and Boko Haram launched offensives and several raids to regain military strength and seize territory in a renewed attempt to establish an Islamic state in the region. These attacks, especially those by ISWAP, met with considerable success and resulted in the displacement of hundreds of thousands of civilians. The member states of the Multinational Joint Task Force (MJTF), namely Nigeria, Niger, Chad, and Cameroon responded to the increased insurgent activity with counter-offensives. These operations repulsed the rebels in many areas, but failed to fully contain the insurgency.

In response to rapid territorial gains made by the Islamic State of Iraq and the Levant (ISIL) during the first half of 2014, and its universally condemned executions, reported human rights abuses and the fear of further spillovers of the Syrian Civil War, many states began to intervene against it in both the Syrian Civil War and the Iraqi Civil War. Later, there were also minor interventions by some states against ISIL-affiliated groups in Nigeria and Libya.

The Multinational Joint Task Force (MNJTF) is a combined multinational formation, comprising units, mostly military, from Benin, Cameroon, Chad, Niger, and Nigeria. It is headquartered in N'Djamena and is mandated to bring an end to the Boko Haram insurgency.

On 17 January 2017, a Nigerian Air Force jet mistakenly bombed an internally displaced persons camp near the Cameroonian border in Rann, Borno State. They had believed it was a Boko Haram encampment. The bombing left at least 115 people dead, including six Red Cross aid workers, and left more than 100 injured.
