The research examined the agitations effect on regional and national security, impending political and economic catastrophe in the southeast regions, and Nigeria’s preparedness and capacity to resolve the protracted dissidence. This study sought to fill a gap in research on understanding radical secession, ethnic sentiments and trigger. Hence, this research utilized the primordialism and instrumentalism theories. The research adopted the qualitative research methodology, utilizing the descriptive design. The researcher using purposive sampling generated primary data through interviews conducted with 10 older respondents and historical narrations from civil war survivors. Secondary data detailing past incident, circumstances and occasions were broadly collated and analyzed using descriptive content analysis. The study thus highlighted after careful analysis that the Igbo people are marginalized, Biafran agitators require autonomy and inclusivity in all spheres of Nigeria’s political, economic, social and developmental road map. The cultural and ethnic indifference of the Igbos constantly triggers the memories of the civil war, resulting in unrest. The research recommends that Igbo people should be aware of their tenacious sense of community in partnership with the Nigerian government should encourage a high-level Peace and Reconciliation module. Strengthening of weak institutions, political inclusion, and economic restructuring are identified as some of the measures that could contribute to addressing the conflict.
