At the start of the 12th century Roger de Poitou joined the failed rebellion against
King Henry I in favor of his brother
Robert Curthose, as 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
