The Ministry of Interior was created in 2015 following a merger between the Ministry of Internal Affairs and the Ministry of Police Affairs. It is a Federal Government Organ which evolved from the Ministry of Internal Affairs which was created in 1957. It came as a result of the merger of various Departments and Units of Government over the years. Some of its components like Prisons were pulled out from the defunct Native Authorities of the Federation; other arms of it, like the Immigration Service, came from the old Nigeria Police Force while other units were previously in the office of the Secretary of State in the Colonial days.
