A religious pluralistic society is a multi-religious society, where the different religious groups have different doctrines of salvation and world views which eventually coent has devindition the style of life, values and ultimate goal of each group. This work set out to examine religious pluralism and constitutional government in Nigeria. Nigeria government claimed to be secular, thus give way for religious pluralism and well entrenched in section 10 of 1999 constitution, yet the Nigeria government still finds it practically impossible to allow for the secular nature of the state. In this work we argue that Nigeria governmated from laid down rules and regulation, and tends to seek to impose one religion on the entire Country. This has been responsible for incessant constitutional crisis in Nigeria.
