Caradog ap Gruffydd

Caradog ap Gruffydd (died 1081) was a Prince of Gwent in south-east Wales in the time of Gruffydd ap Llywelyn and the Norman conquest, who reunified his family's inheritance of Morgannwg and made repeated attempts to reunite southern Wales by claiming the inheritance of the Kingdom of Deheubarth.

However in 1055 Gruffydd ap Llywelyn killed him in battle and took Deheubarth, campaigning through upper Gwent with an army of Welsh, Saxons and Danes to defeat Ralph, Earl of Hereford.

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.

[5] 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.

[6] In 1078 Caradog won another victory over Rhys ab Owain, who had succeeded Maredudd as prince of Deheubarth, killing him too.
