The office of High Sheriff of Montgomeryshire was established in 1541 since when a High Sheriff was appointed annually until 1974 when the office was transformed into that of High Sheriff of Powys as part of the creation of Powys from the amalgamation of Montgomeryshire, Radnorshire and Brecknockshire. Between the Edwardian Conquest of Wales in 1282 and the establishment of the High Sheriff of Montgomeryshire in 1541 the sheriff`s duties were mainly the responsibility of the coroner and the Custos Rotulorum of Montgomeryshire. The Office of High Sheriff remained first in precedence in the County until the reign of Edward VII when an Order in Council in 1908 gave the Lord Lieutenant of Montgomeryshire the prime Office under the Crown as the Sovereign`s personal representative.
