Abia State

Abia is a state in the Southeastern region of Nigeria. The state's capital is Umuahia and its most populous city is Aba.

Abia is bordered the west by Imo, east by Cross River, south by Rivers, northwest by Anambra and northeast by Enugu and Ebonyi. The state is divided between the Niger Delta swamp forests in the south and the Cross–Niger transition forests. The Imo and Aba Rivers flows along the state's western and southern borders respectively. The land for agriculture as well as the production of crude oil and natural gas ranks Abia as the joint-eighth highest Human Development Index in Nigeria since 2019.

Abia's history begins as part of the Aro Confederacy until their defeat in the early 1900s by the British troops during the Anglo-Aro War. After the war, the area was incorporated into the Southern Nigeria Protectorate. After Nigeria's independence in 1960, Abia became part of the post-independence Eastern Region until 1967 before the region was split, and it became part of the East Central State. The Eastern Region attempted to secede in Nigerian Civil War with Abia as part of the secessionist state of Biafra. After the war and the then reunification of Nigeria, the East Central State was merged until 1976 when Imo including Abia, was formed by Murtala Muhammed. Eastern Imo would later become the old Abia State after a split. In 1996, part of Abia's northeast was removed to form a part of the new Ebonyi.

Abia's state legislature is the Abia State House of Assembly. The governors are to serve four years.
