TERRORISM AND AFRICA SECURITY; THE NIGERIAN EXPERIENCE IN THE FOURTH REPUBLIC

Terrorism remains one of the most profound threats to Africa’s stability, undermining national development, regional cooperation, and democratic governance. Nigeria, as Africa’s most populous country and largest economy, has faced sustained terrorist threats throughout the Fourth Republic (1999–present), with implications that transcend its borders. This study investigates the nature, drivers, and impact of terrorism on Nigeria’s national security and Africa’s broader security architecture. Using a qualitative methodology complemented by primary data from expert interviews and field observations, the study focuses on key insurgent groups most notably Boko Haram and its offshoot, ISWAP and assesses the response of the Nigerian state, regional bodies like ECOWAS, and international partners. Findings indicate that terrorism in Nigeria is driven by a complex interplay of socio-economic, ideological, and political factors including poverty, weak governance, ethno-religious tensions, and porous borders. The Fourth Republic, despite democratic gains, has witnessed increased terrorist violence, particularly in the North-East, but also in the North-West and Middle Belt. The study highlights the evolving tactics of insurgents from kidnappings and bombings to territorial control and the Nigerian government’s corresponding counterterrorism strategies. However, challenges such as poor intelligence coordination, limited military capacity, and human rights violations have hampered national and regional counterterrorism effectiveness. Moreover, Nigeria’s experience reflects broader African security concerns, including the spillover of terrorism across Sahelian states, transnational jihadist networks, and the limitations of continental frameworks like the African Union’s APSA (African Peace and Security Architecture). The study concludes that a sustainable solution requires not just military responses, but also robust governance reforms, regional cooperation, and community-based peacebuilding. Nigeria’s experience serves as both a warning and a roadmap for other African states facing similar security threats in the 21st century Key words: Terrorism, African Security, Nigeria, Fourth Republic, Counterterrorism
