This study provides history and analysis of constitution making in Nigeria. It demonstrates that the history can be divided into periods of non-participation, and then gradual participation of Nigerians in the making of their constitution. It analyses the procedure for the making of the 1999 Constitution, and the present position. It advocates for the future, more active or total participation of Nigerians in the constitution making process. The study discusses the development of constitutional law vis-a-vis federalism, the legislature, the executive, the judiciary, local governments and citizenship. All in all, it demonstrates how Nigerians have never been satisfied with their constitutional set-up because of perceived inequalities and injustices caused by the accident of history; and calls for a renegotiation of the basis of the continued existence of Nigeria as a federation, which gives precedence to equity and justice, and representation to the various nationalities making up modern Nigeria.
