Enugu

Enugu State, in Nigeria's South East, was created on 27 August 1991 out of the old Anambra State, taking its name from its capital city, Enugu, meaning "top of the hill" in Igbo. Enugu city rose to prominence in the colonial era as the centre of Nigeria's coal-mining industry and later served as the capital of Eastern Nigeria and, briefly, of the breakaway state of Biafra during the Nigerian Civil War. Known as the "Coal City State", Enugu today functions primarily as an administrative, educational and commercial centre for the wider South East. Its population is predominantly Igbo, and the state hosts several long-established institutions of higher education, including the University of Nigeria's main campus at Nsukka.

Prior to colonial rule, communities in what is now Enugu State, including those around Nsukka and Awgu, were organised as autonomous Igbo village groups. The discovery of coal deposits at Udi in 1909 led to the founding of Enugu township from 1915 as a colonial mining settlement, and the town grew rapidly as coal was railed to Port Harcourt for export. Enugu became capital of the Eastern Region in the 1950s. On 18 November 1949, colonial police shot dead a number of striking coal miners at the Iva Valley mine, an event that galvanised Nigerian nationalist sentiment against British rule. During the Nigerian Civil War, Enugu briefly served as the capital of the secessionist Republic of Biafra in 1967 before falling to federal forces. Enugu State was created on 27 August 1991 from the former Anambra State.

Enugu State straddles a transitional landscape between the lowland rainforest of the South East and higher ground associated with the Udi-Nsukka plateau and the Enugu escarpment, giving parts of the state a hillier terrain than is typical of the wider region. Rivers including the Ekulu and tributaries of the Niger system drain the state. The higher elevations around Udi and Nsukka historically hosted coal seams that were extensively mined through much of the 20th century. Vegetation includes derived savanna and patches of rainforest. Rainfall follows a wet season from April to October, and the state, like its neighbours, experiences gully erosion in some areas, particularly around Nsukka and Udi, linked to the erodible sandy soils common across the region.

Coal mining, once the backbone of Enugu's economy and a major national revenue source through the mid-20th century, declined sharply after the civil war and the shift to oil as Nigeria's dominant export, and the coal industry has not recovered its earlier scale. Today Enugu's economy rests on public administration, trade, education and services, given the concentration of state and federal institutions and universities in and around Enugu city. Agriculture continues in rural local government areas, with yam, cassava, rice and vegetables among key crops, particularly around Nsukka and the Adada valley. The state has sought to diversify through investment in housing, retail and light industry, and its relatively developed road and institutional infrastructure supports a role as a regional service hub for the South East.
