Military coups have re-emerged as a major challenge to regional security and democratic governance in West Africa in the 21st century. Countries such as Mali, Burkina Faso, Guinea, and Niger have experienced repeated unconstitutional changes of government, raising concerns about political instability, weak institutions, insecurity, and the declining trust in democratic leadership. This study examines the causes, implications, and regional security consequences of military coups in West Africa. The study adopts a qualitative research approach using secondary sources such as journals, textbooks, reports, and online publications. It explores factors including poor governance, corruption, electoral irregularities, economic hardship, terrorism, and external influence as major drivers of military intervention in politics. The study further evaluates the role of the Economic Community of West African States (ECOWAS) and other regional bodies in managing conflicts and restoring democratic order. Findings reveal that recurring coups undermine regional integration, economic development, peace, and security efforts within the sub-region. The study concludes that strengthening democratic institutions, promoting good governance, addressing insecurity, and improving socio-economic conditions are essential to reducing the occurrence of military coups and enhancing regional stability in West Africa.

This study examines the role of immigration in Nigeria’s national security, with particular attention to the opportunities and challenges associated with cross-border migration. Immigration has become a major issue in contemporary international relations due to increasing globalization, economic integration, armed conflicts, and regional mobility within West Africa. Nigeria, as one of Africa’s largest economies and a strategic regional power, experiences significant inflows of migrants from neighboring countries, which has implications for its political stability, economic development, and internal security. The study explores how irregular migration, porous borders, human trafficking, smuggling, terrorism, and transnational crimes contribute to national security concerns in Nigeria. It also investigates the positive contributions of immigration, including labor supply, cultural integration, economic growth, and regional cooperation. The research adopts a qualitative approach using secondary data obtained from textbooks, journal articles, government publications, reports from international organizations, and relevant media sources. Theoretical frameworks such as the Human Security Theory and Migration Theory are employed to analyze the relationship between immigration and national security. Findings reveal that weak border management, inadequate immigration policies, corruption, and limited surveillance mechanisms have increased Nigeria’s vulnerability to insecurity, including insurgency, banditry, kidnapping, and illegal arms trafficking. However, the study also finds that effective immigration management can enhance national development, regional peace, and socio-economic stability. The study concludes that immigration plays a dual role in Nigeria’s national security by serving as both a potential threat and a tool for national development when properly regulated. It therefore recommends stronger border control measures, improved intelligence sharing, modernization of immigration systems, regional collaboration among ECOWAS member states, and comprehensive policy reforms aimed at balancing national security with human rights and regional integration.
