Nigeria is facing an unprecedented surge in everyday violence, a situation exacerbated by persistent failures in security systems and deepening public distrust in state institutions. This pervasive insecurity is rooted in decades of interconnected institutional weaknesses that have enabled various forms of organised violence across the country. Non-state armed groups, taking advantage of these vulnerabilities, increasingly challenge the state’s authority and undermine efforts to preserve law and order. Nigeria’s security landscape is currently defined by a complex web of threats, including terrorism, insurgency, banditry, kidnapping, farmer-herder conflicts, separatist agitations, and the activities of organised criminal gangs. These threats have spread rapidly, intensifying instability and creating pervasive fear among citizens. Combative responses by security agencies have so far proven inadequate, revealing the urgent necessity for comprehensive institutional reforms. The growing audacity of armed groups has also compelled communities to form local self-defence initiatives, such as vigilante organisations, further compounding the security matrix. This study critically examines the evolving dynamics shaping Nigeria’s security challenges, utilising a wide range of secondary data sources. It finds that effective solutions must go beyond reactive policing, encompassing targeted reforms and inclusive policies to address deep-rooted socio-economic deprivation and political exclusion. The study concludes that reconstructing Nigeria’s security architecture, alongside efforts to strengthen social cohesion and expand economic opportunity, is essential to reverse the current trajectory and achieve sustainable peace.
