The Mid-Western Region was a division of Nigeria from 1963 to 1991, formally known as Bendel state from 1976. It was formed in June 1963 from Benin and Delta provinces of the Western Region, and its capital was Benin City. It was renamed a province in 1966, and in 1967 when the other provinces were split up into several states, it remained territorially intact, becoming a state. Edo State was formed on August 27, 1991 when Bendel State was split into Edo and Delta States.
