Nigeria, Africa's most populous nation and largest economy, faces a complex and multi-dimensional
security crisis that threatens its stability, development, and democratic progress. Since independence
in 1960, the country has experienced various forms of conflict, but the scale and intensity of insecurity
in the last two decades is unprecedented. Today, insecurity manifests in several forms across Nigeria's
six geopolitical zones: terrorism in the Northeast driven by Boko Haram and Islamic State West Africa
Province (ISWAP); banditry and kidnapping in the Northwest and North-Central; farmer-herder conflicts
in the Middle Belt; separatist agitation in the Southeast; oil theft and militancy in the South-South; and
urban crime and cultism nationwide. The human cost is staggering. According to data from the Council
on Foreign Relations' Nigeria Security Tracker and humanitarian agencies, over 350,000 people have
been killed directly and indirectly due to conflict since 2009, with more than 3 million displaced
internally. The 2023 Global Terrorism Index ranked Nigeria as the 8th most impacted country by
terrorism globally. This eBook examines the root causes of Nigeria's insecurity, evaluates the role of
government institutions, addresses widespread allegations of compromise within state structures,
assesses American and international intervention, and proposes actionable solutions. The goal is to
provide a balanced, evidence-based overview for policymakers, students, and citizens seeking to
understand and resolve this crisis.
