After more than half a century of independence, African countries are stagnating economically, despite their efforts and foreign aid.This economic failure is explained by the economic compartmentalization and the multitude of unreliable economic spaces on the continent.In the context of globalization, Africa is obliged to integrate economically and politically at the risk of remaining behind and dependent on developed countries.Integration appears to be the panacea that can prevent Africa's marginalization from world trade and ensure its socio-economic development.Created in 1975, the Community of West African States (ECOWAS) aims to promote cooperation and integration in West Africa. The author takes stock of ECOWAS, identifies the challenges and obstacles it faces, and suggests ways to accelerate the integration process.
