Rooted in the cosmology, performance, and kinship systems of the Igbo people, oral tradition serves as a living archive through which history is not merely remembered but ritually enacted, spatially grounded, and socially authorized. Far from being anecdotal or supplementary, these oral forms, shrines, genealogies, naming practices, and women’s institutions like the Umuada function as legitimate modes of historical production and communal governance. Drawing on  oral interviews with elders, shrine custodians, and women in Nnewi, Owerri, and Umuahia, this study illuminated  how Igbo oral practices transmit memory, adjudicate disputes, and assert identity across generations. Framed within decolonial and feminist epistemologies, and informed by the works of Jan Vansina, Ifi Amadiume, Walter Mignolo, and Boaventura de Sousa Santos, the paper challenges Eurocentric historiographical hierarchies that equate writing with truth and orality with absence. It foregrounded the embodied, gendered, and spiritual dimensions of Igbo memory, particularly as preserved in women’s dirges, shrine performances, and genealogical recitations. The analysis further reflects on the disruptive impact of colonialism and Christianity, which sought to displace oral systems through textual domination, while tracing how communities resisted through concealment, adaptation, and ritual resilience. Igbo oral tradition emerged not as a vanishing relic of the past, but as a dynamic, ethical, and intellectually rigorous framework for historical knowing one that demands a rethinking of what constitutes evidence, authority, and archive in African historiography.
