Ariam/Usaka is one of the four principal clans of Ikwuano Local Government Area, Abia State, Nigeria.[1][2] Ariam/Usaka belongs to the Isuogu family. Ariam itself is made up of three subgroups namely; Ariam, Ekpiri and Usaka.[3] This clan borders Ibere and Oboro to the north, Oloko to the west, as well as several Ibibio communities in Akwa Ibom State to its eastern and southern borders. Forde and Jones categorized the Isuogu family (Ariam/Usaka and Oloko) in the Ohuhu-Ngwa cluster of the Southern Igbo area.[4]
