The State of Edo was formed in June 1963 from Benin and Delta provinces of the Western Region originally. That region was known as Bendel State, and its capital was Benin City. It was renamed a province in 1966, and in 1967 the other provinces were split up into several states. Bendel remained territorially intact, becoming a state again. However, during the Nigerian Civil War, the Biafran forces invaded the new Mid-Western state, en route to Lagos, in an attempt to force a quick end to the war.
While under Biafran occupaton, the state was declared as the “Republic of Benin” as Nigerian forces were to retake the region. The republic collapsed a day after the declaration as Nigerian troops overtook Benin City. In 1976 it lost Ughelli to the new Rivers state and was renamed Bendel. In 1991 Bendel State was split into Edo and Delta states
