This paper reviews the role of ECOWAS in promoting peace, human right and security in West Africa through the established vision 2020. The function of ECOWAS has always been creating a peaceful and enabling environment for cooperation and regional integration as a tool to enhanced development of the West African economy. Regional integration remains the most viable and appropriate tool for achieving and accelerating peace, human right and security among West African countries. With regard to the above function, the group in June 2007 adopted the transformational vision 2020 focused on the free move-ment of the population, greater access to efficient education and health, engaging in eco-nomic activities, raising the standard of living. This paper examines ECOWAS quest for peace, human right and stability on the continent within the conventional vision 2020. It highlights areas that require review to make peace and security more effective.
