The events leading to the Nigeria Civil War marked the triumph of force and violence over dialogue and negotiation as a means of conflict resolution. The success of the Nigerian state in imposing a military solution on the preceding political crisis, and then suppressing the ensuing Biafran rebellion, has had a lasting effect on state-society relations.
