The origin of the Abiriba people is not as speculative as the origin of other Igbos of southeastern Nigeria. Historical evidence supports the fact that Abiriba people have common ancestry with the Bahumono, Yakor, Ekoi tribes of cross river basin and the people of Arochukwu. At Ekoi, constant disputes between the seven families under Ukpaghiri prompted the clan to move to Ena and finally to Akpa. However, the Abiriba people found it difficult to settle in Akpa due to several issues with neighbours. Nevertheless, the death of Ukpaghiri led to the movement of Mbiriba and his group to Usukpam. Despite staying there for many years, they were still never at peace with the neighbours.
