Biafra (/biˈæfrə/ bee-AF-rə), 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 Chukwuemeka 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 officially 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.
Igbo nationalism became a strong political and social force after the civil war. It has grown more militant since the 1990s, calling for the revival of Biafra as an entity. Various Biafran secessionist groups have emerged, such as the Indigenous People of Biafra, the Movement for the Actualization of the Sovereign State of Biafra, and the Biafra Zionist Front.
