A comprehensive history of one of the world's deadliest jihadist groups Boko Haram is one of the world's deadliest jihadist groups. It has killed more than twenty thousand people and displaced more than two million in a campaign of terror that began in Nigeria but has since spread to Chad, Niger, and Cameroon. This is the first book to tell the full story of this West African affiliate of the Islamic State, from its beginnings in the early 2000s to its most infamous violence, including the 2014 kidnapping of 276 Nigerian schoolgirls. An in-depth account of a group that is menacing Africa's most populous and richest country, the book also illuminates the dynamics of civil war in Africa and jihadist movements in other parts of the world.
