Nigeria is known to have many conflicts with regards to ethnicities, tribes, and religions. In the past, violence had sprung from the different tribes fighting against each other due to their differences. Because there is such a large population in Nigeria, and there is such diversity, conflicts are bound to come up. Currently, the main conflicts are between muslims and christians as traditional religions aren't very prevalent in Nigeria today. Many christian Nigerians fear muslims due to the bad press with regards to extremists and terrorists. Many of the conflicts today rise from a weak government, as well as from the colonial period when English people conquered Nigeria. During the colonial period, many natives felt that the English were taking away their lives, or changing it immensely. This lead to bitterness and a bad reputation with Christianity that soon engulfed Nigeria. Poor security and limited resources does not help with limiting violence between civilians either.
The video below explains the current events that are taking place with regards to violence based on religions in Nigeria.
