Background[edit]
Kano, biggest city in northern Nigeria
Further information: Fourth Nigerian Republic
Before colonization and subsequent annexation into the British Empire in 1900 as Colonial Nigeria, the Bornu Empire ruled the territory where Boko Haram is currently active. It was a sovereign sultanate run according to the principles of the Constitution of Medina, with a majority Kanuri Muslim population. In 1903, both the Borno Emirate and Sokoto Caliphate came under the control of the British. Christian missionaries at this time, spread the Christian message in the region and had many converts.[56] British occupation ended with Nigerian independence in 1960.[57][58][59]
Except for a brief period of civilian rule between 1979 and 1983, Nigeria was governed by a series of military dictatorships from 1966 until the advent of democracy in 1999. Ethnic militancy is thought to have been one of the causes of the 1967–70 civil war; religious violence reached a new height in 1980 in Kano, the largest city in the north of the country, where the Muslim fundamentalist sect Yan Tatsine ("followers of Maitatsine") instigated riots that resulted in four or five thousand deaths. In the ensuing military crackdown, Maitatsine was killed, fuelling a backlash of increased violence that spread across other northern cities over the next twenty years.[60] Social inequality and poverty contributed both to the Maitatsine and Boko Haram uprisings.[47]:97–98
In the decades since the end of British occupation, politicians and academics from the mainly Islamic North have expressed their fundamental opposition to Western education. Political ethno-religious interest groups, whose membership includes influential political, military and religious leaders, have thrived in Nigeria, though they were largely suppressed under military rule. Their paramilitary wings, formed since the country's return to civilian rule, have been implicated in much of the sectarian violence in the years following. The Arewa People's Congress, the militia wing of the Arewa Consultative Forum, the main political group representing the interests of northern Nigeria, is a well-funded group with military and intelligence expertise, and is considered capable of engaging in military action, including covert bombing.[61]
