Hywel Dda

Hywel Dda (Hywel the Good), Hywel ap Cadell (c. 880 – 950), was king of Deheubarth in south-west Wales, who came to rule a large part of Wales through success in battle and marriage. He had regular contact with Æthelstan of England, and his later reign was generally peaceful by the standards of the time; this may be why the Welsh laws were attributed to Hywel Dda. None of the existing Welsh law manuscripts date back to Hywel’s time, and there is no definite link between Hywel and any existing text or section of Welsh law. However, the story in the prologues emphasizes his legal activity.
