ECOWAS was created in 1975 with 15 West African member states and aims to promote economic integration and cooperation in West Africa. It has a population of over 220 million and works toward establishing a monetary union to stimulate economic growth across its 6.1 million square kilometer area. ECOWAS has achieved increased free movement of people and trade, maintained regional peace and security through interventions in member countries, but still faces challenges in coordinating economic policies between members and developing infrastructure for increased intra-regional trade.
