(Sir Drefaldwyn) Border county of mid‐Wales. It was created at the Act of Union with England in 1536 and was coincident with the Welsh kingdom of southern Powys. The English name comes from the French home of the early conqueror, Roger de Montgomery.
There was an early woollen industry in the towns of the Severn valley, and its demise, together with the closure of lead‐mines and greater capitalization of agriculture, led to extensive depopulation. In response, Newtown was developed from 1967 and has a range of light industry. In 1974 Montgomeryshire became a district in the county of Powys and was incorporated in the unitary authority of Powys in 1996.
