2002

Boko Haram was founded in Maiduguri, Nigeria by Mohammed Yusuf as a Salafist movement rejecting Western education and secular governance, laying the ideological groundwork for armed conflict.

2009

Nigerian security forces killed Yusuf and crushed a Boko Haram uprising in Maiduguri, killing over 700 people; the crackdown radicalized survivors and transformed the group into a full insurgency under Abubakar Shekau.

2011

Boko Haram escalated to suicide bombings and complex attacks, including a strike on UN headquarters in Abuja, signaling a shift to large-scale terrorism beyond northeastern Nigeria.

2014

Boko Haram seized roughly 20,000 square miles of territory in Borno State and abducted 276 schoolgirls from Chibok, drawing global attention and prompting a regional military response.

2015

Nigeria, Niger, Chad, Cameroon, and Benin formally activated the Multinational Joint Task Force, recapturing most Boko Haram-held territory but failing to eliminate the group.

2016

A major faction broke from Shekau and pledged allegiance to ISIS, forming Islamic State West Africa Province (ISWAP), which adopted a strategy of targeting soldiers while cultivating civilian populations around Lake Chad.

2021

ISWAP fighters killed Shekau in a battlefield confrontation, absorbing much of his faction and consolidating as the dominant insurgent force across Nigeria, Niger, Chad, and Cameroon.

2023

Despite ongoing MNJTF operations, ISWAP and residual Boko Haram factions continued large-scale attacks on military bases and villages, with the conflict displacing over 2 million people across the Lake Chad basin.
