Ngwa is the largest Igbo group along with Ikwere. Accordingly, the present day Ngwa land was, also, inhabited by Ibibio people. There was a man known as Diobu who was a descendant of Iwhuroha. Subsequently, Diobu left Iwhuroha with his followers and was sheltered by Ibibio-Efik people. Notably, Diobu and his followers were highly polygamous. Extensively, Diobu and his followers married Ibibio-Efik women; and became more populated than their host: Ibibio. This triggered Ibibio people to invade and chase them out. Diobu and his followers joined forces with Ohafia and Abiriba people; and fought Ibibio people from all angles. The Ibibio did not only lose the war; they, also, lost their Land; and were forced to leave what became Abia State.
