In northern Nigeria, high levels of ethnic diversity have resulted in acute polarization between Muslims and Christians, increasingly fuelling violent conflict. The climate of insecurity threatens northern Nigeria's development, accentuates the inequalities between it and the rest of the country, and undermines the attempt to stabilize democracy in the country. Externally, fears have also been expressed that Islamist movements in northern Nigeria form part of a wider network constituting a threat to global peace and security. Refuting a "clash of civilizations" between Muslims and Christians, the authors of this new study highlight the multiplicity of Muslim and Christian groups contending for influence and relevance, and the doctrinal, political and historical drivers of conflict and violence between and within them. They analyse some of the region's most contentious issues: conflict and peacebuilding in Jos; the Boko Haram insurgency; the informal economy; and the challenges of legal pluralism posed by the declaration of "full" Sharia law in 12 Muslim-majority states. Finally, they suggest appropriate and effective policy responses at local, national, and international levels, discussing the importance of informal institutions as avenues for peace-building and the complementarities between local and national dynamics in the search for peace.
