After Gruffudd ap Llywelyn's victory in battle near
Glasbury in 1056, by 1057 Gruffudd was recognized as
King of Wales and Caradog received
Caerleon. From the family's stronghold in Gwent, Caradog appears to have been able to add his
Morgannwg inheritance during his early career. After the defeat of Gruffudd ap Llylewyn by
Harold Godwinson in 1063, old lineages in the south were restored, with Caradog becoming ruler of
Glywysing at about the same time as
Maredudd ab Owain ab Edwin, the male-line heir of
Hywel Dda, became ruler of
Deheubarth.
Contest over Gwent Harold Godwinson subsequently began to build a hunting lodge in
Portskewett. In 1065 Caradog attacked and destroyed Harold's hunting lodge, going on to ravage the district with his forces. Then, after Harold's defeat at the
Battle of Hastings, the Normans sacked south-east Wales and parts of Gwent in response to
Eadric's Herefordshire rebellion in alliance with the Welsh prince of
Gwynedd (and
Powys),
Bleddyn ap Cynfyn. King Maredudd of Deheubarth decided not to resist the Norman encroachment on Gwent and was rewarded with lands in England in 1070, at the same time as the chronicler
Orderic Vitalis noted in his
Historia Ecclesiastica that a Welsh king named "Caducan" (
Cadwgan ap Meurig) suffered defeat in battle at the hands of
William FitzOsbern, 1st Earl of Hereford. == Contest for Deheubarth ==
