18.11 Boko Haram (2002)
Boko Haram was founded in 2002 in northeastern Nigeria by Mohammed Yusuf. It began as an Islamist sectarian movement centered in and around Maiduguri, in Borno State, and it initially attracted followers through preaching, religious instruction, and criticism of corruption, injustice, and the failures of the Nigerian state. The movement later turned to assassinations and large-scale violence.
The group is officially known as Jama’atu Ahlis Sunna Lidda’awati wal-Jihad (Group of the People of Sunnah for Preaching and Jihad). Its more popular name Boko Haram is most commonly translated as “Western education is forbidden.” The term Haram (by itself) is an Arabic term meaning forbidden or sinful in Islamic law (Sharia).
More broadly, the movement rejected not just Western-style schooling, but also the secular political order and what it saw as the corrupt moral and social influence of the modern Nigerian state. Its goal was not merely religious revival, but the replacement of that system with its own version of Islamic rule.
Boko Haram represents a regional jihadist insurgency rather than a primarily political movement like the Muslim Brotherhood or a transnational network like Al-Qaeda.
It emerged from local conditions in northern Nigeria, including poverty, unemployment, weak governance, corruption, and longstanding tensions over religion, law, and state power. In this sense, Boko Haram shows how extremist movements can grow out of local grievances while still developing into large-scale terrorist organizations.

For its first several years, Boko Haram did not operate at the same level of violence for which it later became notorious.
That changed dramatically in 2009, when clashes with Nigerian security forces led to a major uprising. After the revolt was crushed, Mohammed Yusuf was captured and killed in police custody, along with some of his followers.
Rather than ending the movement, this became a turning point that helped radicalize it further. After a short lull, the group resurfaced under the leadership of Abubakar Shekau and launched a far more brutal insurgency beginning in 2010.
Under Shekau, Boko Haram became known internationally for extreme violence, including mass killings, bombings, suicide bombings, village raids, kidnappings, and attacks on schools, markets, mosques, churches, and military targets.
In 2011, they bombed the UN headquarters in Abuja.
One of the most infamous incidents was the 2014 kidnapping of 276 schoolgirls from Chibok, which drew global attention and became a symbol of the group’s brutality. As of 14 April 2024, ten years after the kidnapping, 82 of the girls remained missing and presumed captive.
In 2015, they massacred thousands of civilians in Baga.
Boko Haram also illustrates how Islamist extremist groups can evolve and fragment.
In 2015, Shekau pledged allegiance to ISIS, but the relationship later deteriorated. In 2016, the ISIS central command backed Abu Musab al-Barnawi over Shekau, contributing to a split between Shekau’s faction and what became known as Islamic State West Africa Province (ISWAP). This split shows that even within jihadist movements, there can be major disagreements over leadership, strategy, and the treatment of Muslim civilians.

Although Boko Haram is rooted in Nigeria, its insurgency has affected a wider region around Lake Chad, including Niger, Chad, and Cameroon. The conflict has caused severe insecurity and large-scale civilian suffering across the region. They are responsible for killing tens of thousands of people and displacing more than 2 million.
On April 19, 2026, Boko Haram militants issued a 72-hour ultimatum to the Nigerian government regarding 416 abducted people (mostly women and children) from Borno State. The group has demanded a ransom of approximately $3 million for their release. Militants warned that if demands are not met by the deadline, the captives will be moved to unknown locations where they “may never be seen again.”
Boko Haram demonstrates how a movement shaped by local conditions can still become part of the wider story of modern Islamist extremism. It was not born from the Soviet–Afghan War like Al-Qaeda, and it did not begin as a political-social network like the Muslim Brotherhood. Instead, it grew out of regional instability and then escalated into a brutal jihadist insurgency marked by terrorism, internal fragmentation, and competition with ISIS-linked forces.
In section 18.12, we will examine Al-Shabaab (2006), another regional jihadist insurgency, but one that developed in the very different setting of Somalia’s state collapse and East African conflict.
