The present Ikwuano Local Government Area was part of the Bende Division in the then Southern Province created by the British Colonial Government as part of their “Divide and Rule” system of government and administration towards the beginning of the 19th Century. This was as early as the time Calabar was the capital of Nigeria.

When the Southern province was further divided, Ikwuano still remained part of the Bende Division. The present Bende town was the administrative headquarters where the District Commissioner resided. The District Commissioner, Nwa D.C., as he was known and called held courts at Bende and Oloko. At this time what was later carved out as Aba Division was part of the Bende Division, under the jurisdiction of Nwa D. C. The present Umuahia township later replaced Bende as the administrative headquarters after the extension of the Nigerian rail line from Port-Harcourt to Enugu between 1915 and 1916.

Ikwuano Local Government Area was among the new local government areas that were created on 27 August 1991 when the General Ibrahim Babangida's Administration created Abia State from the old Imo State.[9] It was carved out of the defunct Ikwuano-Umuahia of the Old Imo State.
