History
The northeast was the heart of the Kanem-Bornu empire, one of Africa's longest-lived states. Founded in Kanem, east of Lake Chad, it adopted Islam in about the 11th century, and in the 14th century its Sayfawa rulers moved west of the lake to Bornu, where in the 15th century they built a walled capital at Ngazargamu, in present-day Yobe. Under Idris Alooma in the 16th century Bornu became a formidable military power, trading across the Sahara to North Africa.
In the early 19th century, when the Fulani jihad swept the Hausa lands, Bornu resisted under the scholar Muhammad al-Kanemi, whose descendants became the Shehus of Borno. Further south, the Fulani leader Modibo Adama founded the Adamawa emirate with its capital later at Yola. In the 1890s the warlord Rabih az-Zubayr conquered Bornu, before he was defeated by the French in 1900. Britain then took the western part, and Maiduguri became the capital of Borno. In 1961 the northern part of British Cameroons voted to join Nigeria, bringing in areas including much of the Mambilla Plateau.
In 2009 an uprising by the Maiduguri-based group known as Boko Haram was crushed and its founder, Mohammed Yusuf, died in police custody. The group then waged an insurgency that at its height in 2014–2015 held large areas of territory in and around Borno, abducted 276 schoolgirls from Chibok in 2014, and forced over two million people from their homes. In 2016 a faction split away as ISWAP, and fighting between the two groups, the Nigerian military and neighbouring countries continues. In 2024 floods caused by a dam collapse inundated much of Maiduguri.
