Rys Grig, feudal Lord of Ystrad Tywi and Dynevor, younger son of Rhys ap Griffith, Prince of South Wales. [Burke's Peerage]
Dinefwr Castle was the capital seat of the kingship of Deheubarth. Although legends provide it with a much longer history, there is no evidence that the castle existed before the reign of Rhys ap Gruffudd in the late 12th century. Lord Rhys had managed to create a strong Welsh kingdom which was even recognised by the King of England.
Following the death of Rhys ap Gruffydd in 1197, his sons contested the succession to the kingdom of Deheubarth. Rhys had probably intended that his eldest legitimate son, Gruffydd ap Rhys (d.1201), should inherit the kingdom, but his succession was challenged by two other sons, Maelgwyn ap Rhys (d.1231) and Rhys Gryg (d.1223). A vigorous struggle ensued, and castles were captured and recaptured in a period of prolonged conflict between the brothers, and - after the death of Gruffydd - his sons Rhys Ieuanc ap Gruffydd and Owain ap Gruffydd. The main beneficiaries of this tragic conflict within Deheubarth were outsiders. The English king, Anglo-Norman lords of the March, and native Welsh neighbours, all took advantage until once again the days of independence seemed to be numbered.
For the next two decades the land and castles were constantly fought over, and it was not until the intervention of Llywelyn the Great in 1216 that a settlement was reached by which the kingdom was divided into three parts. Rhys Gryg gained possession of Ystrad Tywi which included the castle of Dinefwr, and he was probably responsible for the earliest stone structures that remain at the castle, including the circular keep.
