Which of the following countries pioneered the idea of ECOWAS alongside Nigeria?

Explanation

Togo was the country which pioneered the idea of ECOWAS alongside Nigeria.

The origin of ECOWAS can be traced to the 1972 when Nigeria's Head of State by then, General Yakubu Gowon and the President of Togo, Gnassingbe Eyadema, had so many meetings about the importance of forming an economic organization for West African States. At last they succeeded to convince other West African leaders about the need to have an economic union. The efforts of these two West African heads of states respectively were rewarded with success when 15 heads of state and government in West Africa came together in Lagos, the capital of Nigeria on 28th May, 1975 and signed the 65-article ECOWAS Treaty.
