History
KEY MILESTONES
2002
FOUNDING
Mohammed Yusuf founds the group in Maiduguri as a non-violent Islamic sect. It gained followers as an alternative to the perceived corrupt Nigerian state.
Mid-2000s
RADICALISATION
First signs of non-compliance with state authority. Radical members begin gaining influence within the movement.
July 2009
ARMED CLASH WITH NIGERIAN POLICE
The Nigerian state attempts a crackdown. Boko Haram fights back. The uprising ends with approximately 800 members killed — including founder Mohammed Yusuf, who is captured and executed without trial in police custody.
2010
CHANGE IN LEADERSHIP
Abubakar Shekau takes command. Yusuf's death becomes a rallying cry. The group transforms into a violent terrorist organisation.
2011
FIRST MAJOR TERROR ATTACK
Suicide bombing of the UN headquarters in Abuja — Boko Haram's first internationally visible attack.
April 2014
CHIBOK SCHOOL ABDUCTION
276 schoolgirls are kidnapped from Chibok, Borno State. The incident sparks the global #BringBackOurGirls campaign.
January 2015
BAGA MASSACRE
An entire village is massacred in the Baga attack — one of the deadliest single incidents attributed to Boko Haram.
March 2015
ISIS ALLIANCE DECLARED
Shekau formally pledges allegiance to ISIS. The group's area of control had grown to roughly the size of Belgium.
2016
FACTIONAL SPLIT
ISIS rejects Shekau's leadership and installs Abu Musab al-Barnawi. The movement fractures into ISWAP (ISIS West Africa Province) and JAS (Jamā'at Ahl as-Sunnah).
May 2021
DEATH OF SHEKAU
Surrounded by ISWAP fighters demanding his surrender, Shekau detonates a suicide vest, killing himself. His stronghold is captured, triggering mass surrenders of JAS fighters.
Key Figures
LEADERS
Founder · 2002–2009
MOHAMMED YUSUF
Born: 29 January 1970.

A charismatic preacher who founded the group as a non-violent movement opposing Western-style governance. Attracted followers from poor and marginalised communities who saw the Nigerian state as corrupt.

Death (2009): Captured by the military during the July uprising and summarily executed without trial in police custody. His extrajudicial killing became a powerful radicalising symbol for his successor.
Leader · 2010–2021
ABUBAKAR SHEKAU
Role: Yusuf's former second-in-command. Took over following the 2009 crackdown.

Even more extreme than his predecessor. Used Yusuf's death as a rallying cry for violent revenge, transforming the organisation into an internationally recognised terrorist group.

Pledged allegiance to ISIS in 2015, elevating Boko Haram to a regional threat.

Death (May 2021): Surrounded by ISWAP fighters, he detonated a suicide vest rather than surrender.
Ideology & Objectives
STATED GOALS
1
Overthrow of the State
Total collapse of the Nigerian federal government and surrounding administrations. Views democracy, the constitution, and any man-made law as Taghut — idolatrous and evil.
2
Implementation of Sharia
Enforcement of a strict, fundamentalist interpretation of Sharia law — not just locally but globally. This is beyond the personal-law application seen in many countries.
3
Caliphate Establishment
Governing a distinct Islamic state centred on the Lake Chad Basin, spanning parts of Nigeria, Cameroon, Chad, and Niger.
Humanitarian Impact
THE HUMAN TOLL
Children killed
300,000+

800,000+
Total displaced persons
2.3 million
Girls abducted (Chibok)
