Observers generally agree that Nigeria offers one of the best case studies or examples of ethno-religious conflicts. Nigeria, which has more than 400 ethnic groups distributed among the two main religions (Christianity and Islam), has experienced a number of inter-religious conflicts since its independence that are estimated to have claimed over three million lives and caused incalculable material and psychological harm. In order to control this social phenomena, which is quickly turning into a permanent aspect of Nigeria's social landscape, this study investigates the manifestations of ethno-religious conflicts in Nigeria, their origins, and makes recommendations for new management measures.
