(Sir Faesyfed) County of mid‐Wales created at the Act of Union with England in 1536. It was part of the Welsh kingdom of Powys but was subject to Saxon attack both before and after the construction of Offa's Dike. It was rapidly overrun by the Normans, the north becoming Mortimer land, whilst the south was taken by the Braoses. These two areas were eventually formed into the new county, the smallest of the Welsh shires. Incorporated into Powys as a district in 1974, it became part of the Powys unitary authority in 1996.
