And what if the opinion of the richest were always the best one ? The breaking down of Fort-Lamy Consensus makes true such a paraphrase of the French writer La Fontaine. This article analyses the cemac sub-region as a sphere of power relations determined by the wealth of the hegemon. The recent enrichment of one of the cemac member states has implied a change of the whole sub-region. This tendency of relating power position to the wealth can give way to hegemonic war, since the tentative efforts to modify the aspect of the power sharing by the rising hegemon oppose the latter to the outgoing hegemon. As far as cemac case is concerned, the war hasn’t occurred like Gilpin put it in his theory of hegemonic change. Yet, one can consider that there is a strong link between the regional integration process conducive to peace, and the struggle for power authorized by the change of wealth from one state to another. Therefore, these two aspects are at the core of entities like regional and sub-regional organizations.
