Concept:The creation of the Economic Community of West African States (ECOWAS) was pushed forward most strongly by the leaders of Nigeria and Togo.
Explanation:ECOWAS was formally established in 1975 with the signing of the Treaty of Lagos.
General Yakubu Gowon of Nigeria was the head of state at that time and championed the idea of closer economic ties among West African countries.
President Gnassingbé Eyadéma of Togo also played a key diplomatic role, using his influence to rally other French-speaking West African nations behind the proposal.
Both leaders used their military standing and political authority to overcome doubts from other member states.
Their combined efforts made it possible for the founding treaty to be accepted and signed by West African heads of state.
Therefore, among the listed options, the two most prominent leaders in the formation of ECOWAS were Gowon and Eyadéma.
