The town of
Middlesbrough had been incorporated as a
municipal borough in 1853. When elected county councils were established in 1889, Middlesbrough was considered large enough for its existing council to provide county-level services, and so it was made a
county borough, independent from the new
North Riding County Council, whilst remaining part of the
North Riding of Yorkshire for ceremonial purposes. The original borough of Middlesbrough was abolished in 1968, merging with several neighbouring authorities to become the
County Borough of Teesside. That proved to be a short-lived local authority, being abolished just six years later when a new borough of Middlesbrough was created on 1 April 1974 under the
Local Government Act 1972. The new borough covered the wards from Teesside which generally corresponded to both the pre-1968 borough and the former parishes of
Hemlington,
Marton and
Stainton (which had all been abolished and absorbed into Teesside in 1968), plus the parish of
Nunthorpe from the
Stokesley Rural District. The re-created borough was a lower-tier district, being one of four districts within the new county of
Cleveland. The county council provided county-level functions.
Cleveland County Council was abolished in 1996 following the
Banham Review and the borough council took over county-level functions, in effect restoring Middlesbrough to the powers it had held prior to 1968 when it had been a county borough. The way the 1996 change was implemented was to create a new
non-metropolitan county of Middlesbrough covering the same area as the existing borough, but with no separate county council; instead the existing borough council took on county functions, making it a unitary authority. At the same time the borough was transferred for ceremonial purposes to
North Yorkshire, but as a unitary authority it has always been independent from
North Yorkshire Council. ==Governance==
