Concept:Federalism in Nigeria was adopted to manage ethnic diversity and protect smaller groups from being dominated by larger ones.
Explanation:Nigeria is made up of many ethnic groups with different languages and cultures.
In a unitary system, a single central government could easily favour the majority ethnic groups.
This would make minority groups feel marginalised and insecure.

This arrangement allows each region to manage its own affairs.
It also gives minorities a stronger voice and greater protection.
