Forced migration and statelessness constitute significant yet often underexamined structural drivers of conflict affecting peace and security across Africa. While frequently framed as humanitarian challenges, both phenomena generate profound governance, legal, and socioeconomic implications capable of intensifying instability where institutional protection mechanisms remain weak. This essay clarifies core concepts relating to forced migration, internal displacement, refugee protection, and statelessness, and evaluates the effectiveness of international, regional, and subregional legal frameworks, including the 1951 Refugee Convention, the 1954 and 1961 Statelessness Conventions, the 1969 Organization of African Unity (OAU) Refugee Convention, and the 2009 Kampala Convention on internally displaced persons. Through doctrinal legal analysis and comparative case studies drawn from the Lake Chad Basin, Côte d'Ivoire, and the Sudan-South Sudan context, the study demonstrates how exclusion from nationality, weak civil registration systems, and inconsistent policy implementation contribute to grievances capable of reinforcing conflict dynamics. Evidence suggests that large-scale displacement may initially intensify competition over resources and heighten communal tensions, particularly where legal identity systems and socioeconomic inclusion mechanisms are insufficiently developed. However, inclusive legal frameworks and coordinated governance approaches may generate stabilizing effects, including economic participation and strengthened social cohesion. The essay identifies key policy gaps including securitization of migration, political resistance to nationality reform, and limited institutional coordination among regional actors. It concludes that strengthening nationality protection, civil registration systems, and regional legal harmonization constitutes an important preventive peacebuilding strategy capable of reducing structural vulnerabilities associated with forced migration and statelessness in Africa.
