The major factor that necessitated the adoption of federalism in Nigeria was the diversity of culture and language. Nigeria is a country with over 250 ethnic groups, each with its unique culture and language. Before the adoption of federalism, the central government was dominated by a few ethnic groups, which created a sense of marginalization among other groups. This led to ethnic tensions and conflicts, which threatened the unity and stability of the country. Federalism was seen as a way to address these challenges by giving more power to the states and allowing them to govern themselves based on their unique cultural and linguistic backgrounds. This would enable each group to have a greater say in their own affairs and reduce the feeling of marginalization. While the intention of creating states and the abundance of natural resources were also factors that influenced the adoption of federalism in Nigeria, the diversity of culture and language was the primary factor. The low level of literacy, on the other hand, was not a factor that necessitated the adoption of federalism, as it was not directly related to the challenges of ethnic tensions and conflicts in Nigeria.
