In the early ninth century, south-east Wales was a kingdom called
Gwent, but for periods in the ninth and tenth centuries it was separated into
Glywysing in the west and Gwent (now
Monmouthshire) in the east, with Glywysing having a higher status. Glywysing was called Morgannwg (now
Glamorgan) from the end of the tenth century.
Norman conquest With Gwent increasingly overrun by the
Norman conquest of Wales, the last native King of Morgannwyg was
Iestyn ap Gwrgan (1081–1090), who was subsequently deposed by
Robert Fitzhamon. Iestyn's sons became Lords of
Afan, while Owain ap Caradog ap Gruffudd contented himself with
Gwynllwg and founded the line of the Lords of
Caerleon. The name
Morgannwg is still used in Wales for the former
Marcher Lordship and county of
Glamorgan (itself a corruption of the term
Gwlad Morgan) and its successor counties == References ==
