From Pledge to Power Struggle
In July 2014, Abubakar Shekau publicly praised global jihadist leaders, including Abu Bakr al‑Baghdadi of the Islamic State. By March 2015, he went further, pledging allegiance and rebranding his movement as the Islamic State’s West Africa Province (ISWAP).
For a time, Boko Haram basked in the prestige of joining a global “caliphate.” But beneath the surface, tensions simmered.
Takfir and Civilian Blood
The core dispute was not geography but theology and tactics. Shekau’s extreme use of takfir—declaring vast numbers of Muslims to be unbelievers—translated on the ground into mass killings of Muslim civilians.
Islamic State’s central leadership, brutal as it was, saw this as counter‑productive. In August 2016, IS announced that Abu Musab al‑Barnawi, son of Boko Haram founder Mohammed Yusuf, would replace Shekau as leader of its West African branch.
Shekau refused. He denounced the move, insisted he still recognised al‑Baghdadi, and took his loyalists with him under the old name Jamā'at Ahl as‑Sunnah li al‑Da'wa wa al‑Jihād—what the world still called Boko Haram.
Three Flags, One Battlefield
By 2017, the insurgency had fractured into at least three main currents:
- ISWAP, aligned with the Islamic State and led by al‑Barnawi.
- Shekau’s Boko Haram, clinging to its maximalist takfir and signature brutality.
- Ansaru, a smaller faction sympathetic to al‑Qaeda and rejecting al‑Baghdadi’s caliphate.
All three rejected democracy, secularism, and Western influence, and all sought some form of Islamic state under sharia. But they fought both the Nigerian state and, increasingly, each other.
Competition in Carnage
From 2018 onward, attacks surged again, particularly in Borno State. ISWAP sought to prove itself the more capable and “disciplined” force, targeting military bases and presenting itself as a protector of ordinary Muslims. Boko Haram responded with its own waves of assaults and kidnappings, eager not to be eclipsed.
The Lake Chad basin became both a sanctuary and a battleground. Climate‑driven poverty and displacement fed recruitment for all sides, and abandoned or captured military equipment—drones, vehicles, weapons—enhanced their capabilities.
The Last Battle of Shekau
The rivalry turned deadly in May 2021. ISWAP gunmen hunted Shekau into his redoubt in the Sambisa Forest. Surrounded, he detonated his own suicide vest rather than be taken alive.
Intelligence reports and intercepted communications confirmed his death. For the first time, the deadliest man in Boko Haram’s history had not been killed by the state he fought, but by fellow jihadists.
In the aftermath, Boko Haram’s remnants briefly rallied under a cleric named Sahalaba before a commander, Bakura Doro, seized control. Under Bakura, the group clawed back strength and in 2023 reportedly pushed ISWAP off several Lake Chad islands and shorelines.
A War Within the War
The split between Boko Haram and ISWAP has not brought peace to civilians. Instead, it has layered rival jihadist agendas onto an already devastated region. Villagers now navigate not just between insurgents and armies, but between insurgents at war with each other.
Yet the infighting also reveals something else: even among extremists who reject democracy and nationalism, questions of authority, legitimacy, and the meaning of “true Islam” can fracture alliances and redraw the map of violence overnight.
