The Welsh lawbooks of the medieval period, the earliest of which is a text of the 13th century, accorded to Dinefwr a special status as the principal court of the kingdom of Deheubarth.
The earliest reference to the castle at Dinefwr in historical sources belongs to the period of Rhys ap Gruffydd, the Lord Rhys.
One of the greatest Welsh leaders of the 12th century, Rhys ap Gruffydd was able to withstand the power of the Anglo-Norman lords of the March, supported on occasion by the intervention of King Henry II (1154-89) of England, and recreate the kingdom.
