Enugu State is a state in the South-East geopolitical zone of Nigeria, bordered to the north by the states of Benue and Kogi, Ebonyi State to the east and southeast, Abia State to the south, and Anambra State to the west. The state takes its name from its capital and largest city, Enugu. The city acquired township status in 1917 and was called Enugwu-Ngwo. Due to the rapid expansion towards areas owned by other indigenous communities, it was renamed Enugu in 1928.

Biafra, officially the Republic of Biafra, was a partially recognised state in West Africa that declared independence from Nigeria and existed from 1967 until 1970. Its territory consisted of the former Eastern Region of Nigeria, predominantly inhabited by the Igbo ethnic group. Biafra was established on 30 May 1967 by Igbo military officer and Eastern Region governor C. Odumegwu Ojukwu under his presidency, following a series of ethnic tensions and military coups after Nigerian independence in 1960 that culminated in the 1966 anti-Igbo pogrom. The Nigerian military proceeded in an attempt to reclaim the territory of Biafra, resulting in the start of the Nigerian Civil War. Biafra was formally recognised by Gabon, Haiti, Ivory Coast, Tanzania, and Zambia while receiving de facto recognition and covert military support from France, Portugal, Israel, South Africa and Rhodesia. After nearly three years of war, during which around two million Biafran civilians died, President Ojukwu fled into exile in Ivory Coast as the Nigerian military approached the capital of Biafra. Philip Effiong became the second president of Biafra, and he oversaw the surrender of Biafran forces to Nigeria.
