Abstract
The public administration system of any country is inherently shaped by its populace – their intercommunications and historical contexts. Nigeria, as a multi-tribal society, forged through British colonial rule, presents a complex administrative framework influenced by its vast tribal diversity. This paper explores the extent to which tribal affiliations have impacted public administration in Nigeria, tracing their influence from the colonial period to contemporary public administration. Adopting a conceptual methodology, the research is grounded in secondary sources including academic articles, books, newspapers, and legal documents such as the Nigerian Constitution. Although findings show the persistence of tribal conflicts within administrative processes in Nigeria, the study emphasizes that the effective functioning of the public administration system is deeply contingent on fostering tribal unity and promoting interethnic collaboration.
