At the time of Domesday Book in 1086, parts of the county were considered either to form part of Yorkshire or to be within the separate Kingdom of Strathclyde. The Normans conquered the area that is now Cumbria in 1092 during the reign of William II and created the baronies of Kendal and Westmorland. These were originally distinct jurisdictions with separate sheriffs, but were formed into a single county of Westmorland in 1226/7. Before 1226 the Barony of Kendal was connected to the Earldom or Honour of Lancaster while that of Westmorland was part of the Earldom of Carlisle.
