United Nations peacekeeping in Africa has evolved from ceasefire monitoring into multidimensional intervention encompassing civilian protection, political transition, electoral assistance, disarmament and post-conflict peacebuilding. Yet broader mandates have produced markedly different outcomes across missions. This paper examines the evolution and operational experience of UN peacekeeping through a comparative analysis of operations in Namibia, Mozambique, Rwanda, Somalia, Angola and Burundi. It considers how political and operational conditions interacted to shape mission outcomes, focusing on commitment to negotiated settlements, acceptance of electoral outcomes, mandate credibility, management of spoilers, disarmament, regional cooperation and sustained international engagement. The comparison shows that Namibia and Mozambique benefited from conditions that enabled peacekeeping to reinforce viable political settlements and support the movement of political competition from armed confrontation into institutional processes. Rwanda demonstrates the consequences of inadequate capability and political commitment in a rapidly deteriorating security environment, while Somalia illustrates the limitations of coercive intervention in the absence of a viable political settlement. Angola highlights the fragility of peace implementation when powerful actors retain military alternatives to electoral competition, whereas Burundi demonstrates the contribution of multidimensional peacekeeping within a longer process of domestic negotiation and regional engagement. The paper argues that the evolution of UN peacekeeping in Africa is better understood through the relationship between political settlement and operational intervention than through mandate expansion alone. Durable outcomes are more likely where political commitment, credible mandates, operational capacity and regional support reinforce one another. These findings underline the need for politically grounded and operationally realistic peacekeeping strategies capable of supporting institutions that can sustain peaceful political competition beyond mission withdrawal.
