a result losing his English holdings. In 1102 King Henry granted the whole of Blackburnshire and part of Amounderness to Robert de Lacy, the Lord of Pontefract, while confirming his possession of Bowland. These lands formed the basis of the Honour of Clitheroe. Subsequently most of the ancient parish of Ribchester, except the township of Alston-with-Hothersall, and in the ancient parish of Chipping, the vills of Aighton and Dutton and part of the forest of Bowland belonging ecclesiastically to the ancient parish of Great Mitton were annexed to Blackburnshire. The separateness of the district was reinforced when it became a royal bailiwick in 1122. In 1182, it became part of the newly created County Palatine of Lancaster. By 1243 it is believed that there were 57 manors in the hundred. Those held in demesne were Colne, Great and Little Marsden, Briercliffe, Burnley, Ightenhill, Habergham, Padiham, Huncoat, Hapton, Accrington, Haslingden, Downham, Worston, Chatburn and Little Pendleton. Those held by thegnage were: Twiston, Chipping, Thornley, Wheatley, Ribchester, Dutton, Dinckley, Henthorn, Wilpshire, Clayton-le-Dale, Salesbury, Osbaldeston, Samlesbury, Read, Simonstone, Oswaldtwistle, Livesey, Birtwistle, Church, Cliviger and Worsthorne. Those held by knight's service were: Little Mitton, Wiswell, Hapton, Towneley, Coldcoats, Snodworth, Twiston, Extwistle, Aighton, Great Mearley, Livesey, Downham, Foulridge, Little Mearley, Rishton, Billington, Altham, Great Harwood, Clayton le Moors, and Walton in le Dale. Post medieval The hundred of Blackburnshire continued to have administrative relevance until the abandonment of the system of hundreds in the early 19th century, long after feudalism ceased in England. As in other parts of England, the hundred was divided into parishes which were ecclesiastical parishes as well as being used for administrative purposes, like modern English civil parishes. Early Blackburnshire had only two parishes, each covering a considerable but sparsely populated area. Whalley (now a much smaller parish) was the larger of the two, and covered the east of the hundred, while Blackburn parish covered the west. As mentioned above, the hundred was expanded to cover parts of the parishes of Chipping, Ribchester and Mitton. As Blackburnshire became more heavily populated and economically developed, the parishes of Whalley and Blackburn were split into many smaller parts over the centuries. The ancient parish of Blackburn contained Blackburn, Little Harwood, Ramsgreave, Salesbury, Clayton-le-Dale, Mellor, Witton, Pleasington, Over Darwen, Lower Darwen, Eccleshill, Tockholes, Livesey, Walton-Le-Dale, Cuerdale, Samlesbury, Balderston, Osbaldeston, Billington, Wilpshire, Dinckley, Great Harwood, Rishton. It also included Yate and Pickup Bank with extra-parochial
