Diversity refers to the combination within a population of people with different backgrounds. These differences can be ethnic, religious, socioeconomic, and gender imbalances within a group. The law on the other hand represents the laid down rules for governance or the maintenance of stability within a system. This paper examines diversity and the law with reference to Nigeria. The paper discusses the historical overview of the Nigerian nation as it helps us to understand the root of the diversities in the nation. It further discusses the challenges or problems that have helped deepen the diversities rather than uniting the people. The paper furthers discusses the constitutional provisions that should help us to see our diversities as our strength. The paper highlights the breaches of these provisions where they have occurred. It notes that the most fundamental issue to sustaining our diversity is the crafting of a federal constitution that would entrench true federalism. Several recommendations which include the separation of state and religion, independence of the judiciary and the elimination of socioeconomic inequities were made. The paper concludes by urging the government to rise up to the task of uniting Nigerians by making policies that are fair and equitable to all.
