Oral tradition history traces the origin of Aguleri to a man named Eri. Eri settled at the bank of the river where he made an altar of onyx at the confluence of Ezu na Omabala rivers. ^{[citation needed]}Due to annual flooding of the place Eri moved upland to Eri-aka near odanduli stream and finally to where he erected Obu Uga (Obu-Gad). Eri had the following children 1. Agulu (Aguleri) 2. Attah 3. Oba 4. Menri 5. Adamgbo (Iguedo the only daughter of Eri). All the children of Eri lived together with their father in Aguleri until after the death of Eri when his sons scattered in different places where they are founder of different kingdoms. Attah the second son of Eri left and founded Igala kingdom while Oba moved to found Benin kingdom. Menri later left Aguleri where he founded Nri kingdom. Eri first son Agulu-eri (Aguleri) remained behind and inherited his father's land and expanded the kingdom. Aguleri married three wives namely Ada, Omali and Eke and had four sons namely 1. Ivite 2. Igboezunu 3. Enugwu. 4. Eziagulu.

Note: Ada the first wife did not conceived on time, Agulu (Aguleri) had to marry Omali (second wife) who conceived and bore him a son called Ivite (first son). God remember Ada the first wife of Agulu (Aguleri) and she conceived and bore a son called Igboezunu (second son). Agulu (Aguleri) had to marry the third wife Eke who God blessed with two sons namely Enugwu (third son) and Eziagulu (fourth son). This three wives of Aguleri formed Akwukwonato.^{[citation needed]}
