Since independence, Nigeria has made effort to clearly articulate the relationship between her differing ethnic groups and religious biases. To find a working relationship seems difficult because of factors like internal contradictions propagated by the colonial authority, contradicting worldviews of ethnic groups, and conflicting religious beliefs. The concept of "one Nigeria" appears fictitious. This sparked calls for both a united and divided Nigeria. While the north clamour for one Nigeria administered according to Islamic law, the south is agitating for independence from the north's servitude. This work situates the paradoxical quest for a united and a divided Nigeria in a multi-ethnic and multi-religious environment, using a historical approach basically depending on secondary sources. The quests are contrary to general belief and are parallel socio-economic evils in relation to the nature of Nigeria. The work advocates for the "lesser evil" (a dividedd Nigeria) since it could not suggest a new option.
