African states have responded to the challenges of the post-Cold War international system mostly by collectively promoting subregional and continental-wide initiatives in conflict resolution and peacebuilding. Admittedly, the existence of many violent conflicts in Africa, as well as their ‘domino’ effects at thesub-regional level, contributed significantly to the growing desire for collective security systems and conflict management mechanisms. The broadening of the role and functions of African regional organisations to include responsibility for peacebuilding and conflict management generally adds credence to the efficacy of regional integration. Many issues, however, present themselves in the engagement of RECs with the peacebuilding process in Africa. Although primarily set up to promote economic integration, Africa’s RECs have increasingly taken up a prominent role in conflict resolution and peace support operations, as evident in the recent peace processes in Burundi, Liberia, Sierra Leone, Guinea, Guinea-Bissau, Mali, Cote d’Ivoire, Zimbabwe, Mali, Congo DRC, Sudan, and South Sudan, among others. In spite of the challenges they face, RECs are capable of playing important roles with regard to peace mediation, peacekeeping and peacebuilding.
