ECOWAS HQ.

**The reasoning** ECOWAS (Economic Community of West African States) is a regional bloc of 15 West African countries working together for economic integration and cooperation. The organization's headquarters moved to **Abuja, Nigeria** in 2003. Nigeria was chosen because it's the most populous country in West Africa and has been a major driving force behind ECOWAS since its establishment in 1975. Abuja, being Nigeria's capital, provided a central, purpose-built city for hosting the secretariat. **Why the wrong options tempt you** - **Accra (Ghana)** — Ghana is another ECOWAS powerhouse and hosts many other regional organizations, making it a reasonable guess. - **Lomé (Togo)** — Some confuse this with UEMOA (West African Economic and Monetary Union) headquarters, which is actually in Ouagadougou. - **Dakar (Senegal)** — A major West African city, but it hosts the African Union of Railways, not ECOWAS. **Quick takeaway** Remember: **Nigeria houses ECOWAS** — both are giants of West Africa, so the biggest organization sits in the biggest country's capital.
