Start here: Meaning and origin of ECOWAS

ECOWAS (Economic Community of West African States; in French, CEDEAO) is a regional economic organisation of West African countries formed to promote cooperation and integration in economic, social and political activities.

Origin

After independence, West African countries had small, separate economies with weak links to each other and strong links to former colonial powers.
Leaders, notably General Yakubu Gowon of Nigeria and President Gnassingbé Eyadéma of Togo, championed a regional community.
The Treaty of Lagos was signed on 28 May 1975 by 15 founding states.
Cape Verde (now Cabo Verde) joined in 1977 (some ECOWAS pages say 1976), bringing membership to 16. Mauritania withdrew in December 2000.
A Revised Treaty was signed in Cotonou in 1993, expanding aims to include political cooperation, peace and security, and a common market.
The ECOWAS Secretariat became the ECOWAS Commission in 2007. Its headquarters is in Abuja, Nigeria.
In 2025 ECOWAS marked its 50th anniversary (ECOWAS@50).

The geography of the ECOWAS region

West Africa stretches from the Atlantic coast of Senegal and Cabo Verde in the west to Nigeria’s border with Cameroon in the east, and from the Gulf of Guinea northwards into the Sahel. The region shows the same belts of climate and vegetation studied in gg5 and gg6: humid rain forest along the southern coast (Liberia, Sierra Leone, southern Côte d’Ivoire, Ghana and Nigeria), savanna in the interior, and semi-arid Sahel in the north. Great rivers, especially the Niger, the Volta, the Senegal and the Gambia, cross national borders, so water use must be shared. Coastal members have ports; landlocked states (such as Mali, Burkina Faso and Niger, now outside ECOWAS) depend on their neighbours’ ports and corridors, which is one reason why regional cooperation matters.

Nigeria dominates the region: it has the largest population (UN estimate about 237.5 million in 2025, see gg14) and the largest economy, which brings both leadership and suspicion of domination.

Why regional integration?

Small national markets limit industry; a regional market of hundreds of millions attracts investment.
Neighbouring countries share borders, rivers, peoples and problems.
Cooperation strengthens bargaining power in world trade.
Joint projects (roads, power, telecommunications) are cheaper together.
Peace and security require collective action.
