In Cameroonian societies like elsewhere in Africa, people narrate their history of origin linked to myths and legends. The people of Warr and Tang clans of Mbum ethnic group have specific sites where they migrated before settling on the Nkambe Plateau. This study examines the path history holds from scientific investigations where the Warr and Tang clans originated. From historical findings, the clans migrated at different epochs from Kimi in the present-day Adamawa Region of Cameroon. While on the plateau, the Warr myth holds that, they emerged from a water pool and first settled at Mbiribo before establishing secondary settlements. The Tang on their part hold strongly to their legend of the striped field mouse that gave them the idea on how to cross River Kofatar and it subsequently led them to Talla, and conversely they separated to established different settlement sites. The study demonstrates how myths and legends contribute to historical construction, by pointing out the real meaning inbuilt in myths and legends, which are used metaphorically. In historical appraisal, this paper argues that myths and legends constitute an integrated factor in communities co-existing and reconstruction of history.
