GRUFFYDD ap RHYDDERCH ap IESTYN (d. 1055 ), king . When Gruffudd ap Llywelyn (q.v.) took possession of Deheubarth in 1044 , the South found a new focus of resistance in the leadership of Gruffydd ap Rhydderch . Independence was thus retrieved in 1045 , and for ten years, until his fall in 1055 , Gruffydd gave to his adopted ‘patria’ a vigorous government in which resistance to the Danes was a prominent feature. The sanction for his intervention in the affairs of Deheubarth came in part from his father's successful usurpation of power there during the years 1023-33 . Gruffydd , moreover, was already a ‘ king ’ in Glamorgan , probably over Gwynllwg , where his descendants enjoyed restricted power down to 1270 .
