1.1 Background of the Study
The concept and practice of economic integration between or among states has an old history. By literature available to the researcher, it dates back long before the period of the Berlin Conference in 1884, when African nations thrived on cooperation and community life to re-solve challenges and develop their communities1. Relative to the Economic Community of West African States (ECOWAS), it is as old as the community itself. Indeed, it is the raison d‘être for the formation of the community. Article 3 of the ECOWAS treaty sets out the aims and objectives which among others are to promote cooperation and integration leading to the establishment of an economic union.
West Africa is the part of Africa that is bounded in the West and South by the Atlantic Ocean, the Sahara desert on the North, and on the East by the eastern boundaries of present day Nigeria. Practically, it is that area of Africa that is encircled in the North by a line run-ning from the Senegal River to Lake Chad, in the East by a line running from Lake Chad Ba-sin to the Cameroon Mountains, and in the south and west, by the Atlantic Ocean coastline.2
Traditionally, the peoples of West Africa have earned their living from the land which ac-counts for why agriculture remains the bedrock of all other indigenous economic activity in West Africa. Other occupations such as trade and craft manufacture were rather undertaken on a part time basis, while additional types of productive enterprises were often made possi-ble by the financial surplus from agriculture. The arrival of the Europeans on the west coast of Africa between the 17th and 18th centuries drastically changed the nature of economic ac-

tivities in West Africa, resulting in a ‗profitable trans-national commercial enterprise‘ which for centuries severely retarded socio-economic development throughout West Africa. Also, the resultant partitioning and subsequent introduction of European colonial governance in West Africa with its colonial policy of legitimate trade in one or two cash crops to serve the industrial needs of Europe further worsened the resultant erosion of indigenous industrial skills and the basis for the development of sustainable interactive economic activities throughout West Africa.
In consequence therefore, by the time most of the new nation states of West Africa gained their independence in the 1960‘s, they were left with structurally fragile and highly disarticu-lated economies with inherent acute and devastating price distortions in the international commodity market.
Efforts to co-ordinate economic cooperation on a sub-regional level in West Africa dates back to 1963, with a conference on industrial harmonization in the sub-region in Lagos, Nige-ria, followed by the Niamey conference on economic cooperation in 1966. Similarly in 1967, another conference was held in Accra, Ghana where a tentative agreement on the Articles of Association of a proposed economic community in West Africa was signed.
