From the time of its first settlement the district was the scene of constant border warfare with the Welsh, and Harold, whose earldom included this county, ordered that any Welshman caught trespassing over the border should lose his right hand. In the period preceding the Conquest much disturbance was caused by the outrages of the Norman colony planted in this county by Edward the Confessor. Richard I's castle in the north of the county was the first Norman fortress erected on English soil, and Wigmore, Ewyas Harold, Clifford, Weobley, Hereford, Donnington and Caldicot were all the sites of Norman strongholds. Then William the Conqueror entrusted the subjugation of Herefordshire to William FitzOsbern, but Edric the Wild, in conjunction with the Welsh, prolonged violent resistance against him for two years.
