. The powers of the marcher lordships were abolished, and their areas formed into new counties, or amalgamated into existing ones. At this point, the boundary between England and Wales, which has existed ever since, was effectively fixed. In the border areas, five new counties were created: Denbighshire, Montgomeryshire, Radnorshire, Brecknockshire and Monmouthshire; and Flintshire gained some additional territory. However, several of the marcher lordships were incorporated in whole or in part into English counties.

were included in Herefordshire. According to John Davies:
Thus was created the border between Wales and England, a border which has survived until today. It did not follow the old line of Offa's Dyke nor the eastern boundary of the Welsh dioceses; it excluded districts such as Oswestry and Ewias, where the Welsh language would continue to be spoken for centuries, districts which it would not be wholly fanciful to consider as ''Cambria irredenta''. Yet, as the purpose of the statute was to incorporate Wales into England, the location of the Welsh border was irrelevant to the purposes of its framers.


Changes to the border after 1536

* There was a serious proposal to transfer English Maelor to England in the 19th century one of many changes proposed by the boundary commission. * Due to outrage over plans for county reforms in 1971, the civil parish of Brilley was given the chance to vote on whether to join Wales or stay in England. They decided to remain in England.


Monmouthshire

Although Monmouthshire was included in the 16th century legislation, it was treated anomalously, with the result that its legal status as a Welsh county fell into some ambiguity and doubt until the 20th century. It was omitted from the second Act of Union, which established the Court of Great Sessions, and like English shires it was given two

, within England. The 1911 Encyclopædia Britannica unambiguously described the county as part of England, but noted that "whenever an act ..is intended to apply to alesalone, then Wales is always coupled with Monmouthshire". Some legislation and UK government decisions, such as the establishment of a "Royal Commission on Ancient and Historical Monuments in Wales and Monmouthshire" in 1908, referred to "Wales and Monmouthshire", so that it was treated as one with Wales rather than as a legal part of Wales. The county's status continued to be a matter of debate in Parliament, especially as Welsh nationalism and devolution climbed the political agenda in the 20th century. In 1921 the area was included within the
