The Standing Mediation Committee (SMC) is harbinger of ECOWAS Security Mechanism, which is the abbreviation of the Mechanism for Conflict Prevention, Management, Resolution, Peacekeeping and Security. The study basically delineated different stages in the evolution of ECOWAS Security Mechanism (ESM) with focal point on the impetus, challenges and achievements. It argues that although the developmental processes began before the establishment of the SMC, the structured system derived it foundation from it. From this foundation sprang forth the mansion of a highly structured, well organized, legally codified, generally acceptable and certified ESM, which prides itself as the most formidable system of managing conflict in Africa. This has decisively managed conflicts in countries like Cote dâ€™Ivoire, Liberia, Guinea Bissau, Sierra Leone, and Mali. The initiative of the SMC was not only recognized by the United Nation but adopted by it as they co-deployed with the ESM. Regional and sub-regional organizations like AU, SADC, ECCAS etc. are also tapping from its fountain as a model worthy of emulation. The study recommends that the newly established ECOWAS Standby Force should be well equipped and combat ready to serve the objectives of ESM.
