What happened
Boko Haram was founded in 2002 in Maiduguri, capital of the northeastern state of Borno, by the Islamist cleric Mohammed Yusuf as a Salafist preaching movement whose popular name translates roughly as Western education is forbidden. In July 2009 a confrontation with security forces set off an armed uprising across Borno, Yobe, Bauchi, and Kano that the army suppressed at the cost of more than eight hundred lives, after which Yusuf was killed in police custody in what human-rights groups call an extrajudicial execution. His death radicalized the movement into a violent insurgency under Abubakar Shekau. Over the following years Boko Haram carried out mass bombings, kidnappings, and village massacres; on April 14, 2014, it abducted more than two hundred schoolgirls from the town of Chibok, an atrocity that drew global attention. The group aims to establish an Islamic state and impose sharia across Nigeria, and its insurgency continues to destabilize the northeast and the wider Lake Chad basin.
Why it matters
The Boko Haram insurgency is the deadliest security crisis of Nigeria's democratic era, killing tens of thousands, displacing millions, and exposing the state's difficulty in governing and protecting its poorest northeastern regions. The Chibok kidnapping made it a global symbol of the threat, while the killing of Yusuf in custody illustrates how heavy-handed state responses helped turn a local sect into a regional war.
How we know
The origins, the 2009 uprising, Yusuf's death, and the Chibok abduction are documented in Council on Foreign Relations analysis and in Public Broadcasting Service reporting drawing on contemporary accounts.
