Under the Laws in Wales Acts 1535–1542 introduced under Henry VIII, the jurisdiction of the marcher lords was abolished in 1536. The acts had the effect of annexing Wales with England and creating a single state and legal jurisdiction, commonly referred to as England and Wales. The powers of the marcher lordships were abolished, and their areas were organised into the new Welsh counties of Denbighshire, Montgomeryshire, Radnorshire, Brecknockshire, Monmouthshire, and Carmarthenshire. The counties of Pembrokeshire and Glamorgan were created by adding other districts to existing lordships. In place of assize courts of England, there were Courts of Great Sessions. These administered English law, in contrast with the marcher lordships, which had administered Welsh law for their Welsh subjects. Some lordships were added to adjoining English counties: Ludlow, Clun, Caus and part of Montgomery were incorporated into Shropshire; Wigmore, Huntington, Clifford and most of Ewyas were included in Herefordshire; and that part of Chepstow east of the River Wye was included in Gloucestershire.
