Clwyd is a preserved county of Wales, situated in the north-east, bordering England with Cheshire to its east, Shropshire to the south-east, and the Welsh counties of Gwynedd to its immediate west and Powys to the south. It additionally shares a maritime border with the metropolitan county of Merseyside along the River Dee. Between 1974 and 1996, it was a county with a county council, and it was divided into six districts. It is named after the River Clwyd, which runs through the region. It was also a Royal Mail postal county before the postal county scheme was abolished in 1996. Clwyd County Council was based in the county town of Mold.
From the late 1950s, the radical reform of local government in Wales was considered more pressing than that in England, due to the small size of many of the existing authorities, especially the upper tier county councils. The Local Government Commission for Wales set up in 1958 was the first to recommend wholesale amalgamation of the administrative counties outside Glamorgan and Monmouthshire, with extensive boundary changes; however the then Minister of Housing and Local Government Sir Keith Joseph decided not to accept the report, noting that county amalgamations in England had been highly unpopular when proposed.
