The Boko Haram insurgency began in 2009, when the jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria. In 2012, tensions within Boko Haram resulted in gradual split of the group between Salafist conservative faction led by Abu Usmatul al-Ansari, and the more dominant, violent faction led by Abubakar Shekau. By 2015, part of the group split into al-Qaeda affiliated Ansaru, and Shekau's faction became ISIL's West Africa branch. In 2013, over 1,000 people died as a result of the conflict. The violence escalated dramatically in 2014, with 10,849 deaths. In 2014, the insurgency spread to neighboring Cameroon, Chad, and Niger thus becoming a major regional conflict. In 2015, a coalition offensive forced Boko Haram to retreat into the Sambisa Forest. The insurgency took place within the context of long-standing issues of religious violence between Nigeria's Muslim and Christian communities. Boko Haram has been called the world's deadliest terrorist group, in terms of the number of people it has killed.
