Nigeria since independence has been mired in development challenges. These challenges have been made more complex by the multi-ethnic character of the Nigerian state as well as the mutual fears of domination that have pervaded the nation. This is even aggravated by the type of federalism we are operating as a country. Indeed, this has impacted negatively on the country, stalling its socio-economic development. This paper argues for true federalism as a catalyst for socio-economic development in Nigeria. The paper relies heavily on secondary sources of historical data. The paper, therefore, concludes by recommending devolution of power to all the federating states that form Nigeria as a way out, among others.
