Nigerian Civil Conflict: Timeline & Latest Developments

Nigeria has spent the seventeen years since 2009 fighting three overlapping security crises rather than one war, and this page tracks all three together because that is how Nigerians experience them: as a combined toll on one country. The largest and longest-running is the jihadist insurgency in the northeast, where Boko Haram, founded by Mohammed Yusuf in Maiduguri in 2002 as a Salafist preaching movement, turned to armed rebellion in July 2009 after security forces killed Yusuf in police custody without trial. Under successor Abubakar Shekau, the group became one of the world’s deadliest militant movements, seizing towns across Borno, Yobe, and Adamawa states, declaring a short-lived “caliphate” after capturing Gwoza in August 2014, and carrying out the April 2014 Chibok kidnapping of 276 schoolgirls that turned the insurgency into a global story via #BringBackOurGirls. A reinforced Multinational Joint Task Force of Nigerian, Chadian, Nigerien, and Cameroonian forces pushed the group out of most held territory by mid-2015, but it split in 2016 when Islamic State leadership recognized rival commander Abu Musab al-Barnawi as head of what became ISWAP, separating from Shekau’s faction, which kept the Boko Haram name. Shekau died by suicide vest in May 2021 rather than surrender to an ISWAP offensive on his stronghold in Sambisa Forest. ISWAP has since become the more capable faction, escalating attacks on military bases across Borno and Yobe since 2025, while Shekau’s old faction fights on separately. The UN estimated in January 2026 that more than 40,000 had died and 3.5 million had been displaced since 2009, a broad aggregate rather than a precise count, given how hard verification is inside active conflict zones.

The second crisis runs through Nigeria’s Middle Belt, mainly Plateau, Benue, and southern Kaduna states, where predominantly Muslim Fulani cattle herders and predominantly Christian and traditionalist farming communities clash with escalating lethality over grazing land, water access, and cattle routes squeezed by population growth and climate-driven desertification. It is not a new conflict, but it has deepened since 2018: gunmen attacked eleven Berom farming villages in Barkin Ladi that June, killing somewhere between 86 (the initial police count) and 233 (a church-led tally); Christmas Eve attacks in December 2023 killed close to 200 across Plateau villages; and renewed violence killed 30 more the following January. Survivors and officials have consistently identified the attackers as Fulani herdsmen, while Fulani representatives reject collective blame and point to a cycle of reciprocal attacks stretching back years. In August 2023, House Speaker Tajudeen Abbas told a parliamentary committee that more than 60,000 people had died in farmer-herder violence nationwide since 2001, a legislative estimate but the most-cited figure for a conflict with no single coordinating actor and no dedicated UN tracking mechanism.

The third and most recent crisis is the banditry and mass-kidnapping wave centered on Zamfara, Katsina, Kaduna, Sokoto, and neighboring northwestern states, where armed criminal gangs, some rooted in cattle rustling and some led by former herders, have built a kidnapping-for-ransom economy that targets entire schools. The pattern became internationally visible with the December 2020 abduction of more than 300 boys from a school in Kankara, Katsina State, an attack Boko Haram initially claimed but which officials later attributed to local bandit gangs, an early sign that claims of responsibility here are often contested and unreliable. The 344 Kankara boys were released within a week through negotiations involving so-called “repentant bandits” as intermediaries. A similar attack in March 2024 saw more than 200 students abducted from a school in Kuriga, Kaduna State, almost exactly ten years after Chibok; they were released unharmed after 16 days. Researchers have documented a worrying convergence between some bandit networks and jihadist groups, though most bandit violence stays criminal rather than ideological. Wikipedia’s aggregated tracking put the toll at more than 12,000 killed and 450,000 displaced since roughly 2011, with one widely cited breakdown putting deaths at 8,300 across five northwestern states between January 2013 and March 2022 alone. The line between the northeast insurgency and northwestern criminal violence blurred further in January 2026, when gunmen abducted an estimated 163 to 172 worshippers from two Kaduna churches during Sunday services; no group claimed responsibility, reporting attributed the attack only tentatively to “believed” herdsmen, and Kaduna’s state government initially denied the abductions had happened at all.

That attribution problem sits at the center of the most consequential recent development: in October and November 2025, President Trump designated Nigeria a Country of Particular Concern and threatened to send US troops “guns-a-blazing” or strike Nigeria directly, citing what he described as a mass killing of Christians. Nigeria’s government rejected the genocide framing, noting that Boko Haram and ISWAP kill and displace Muslims and Christians alike, that the deadliest insurgency violence sits in the majority-Muslim northeast, and that Middle Belt and northwest violence, whatever its disproportionate impact on some Christian communities, is entangled with land, ethnic, and criminal dynamics that resist a single religious narrative. Independent researchers generally find the available data supports neither the “genocide” framing nor a blanket denial that religion plays any role. What followed the threats was narrower than the rhetoric: the US deployed roughly 200 personnel to the Lake Chad Basin in February 2026 to support Nigerian counter-ISWAP operations, a joint strike killed a man officials described as ISIS’s global second-in-command, Abu-Bilal al-Minuki, in May 2026, and by July the US had withdrawn most of that deployment while keeping intelligence-sharing in place. All three conflicts remain active, with no ceasefire or peace process capable of resolving even one of them, let alone all three at once.
