Oke Nnachi was the son of Nnachi[1] and possibly introduced the idea of bringing Akpa troops to help the Eze Agwu, Nnachi clan, and Obong Okon Ita rebels during the Aro-Ibibio Wars. After the short dynasty of Osim and Akuma Nnubi of Akuma, Oke Nnachi became king of Arochukwu. His descendants still retain the throne.
