The dynasty of the Cadelling, also known as the House of Deheubarth or the House of Dinefwr after its seat in the late twelfth and early thirteenth centuries, was a medieval Welsh dynasty founded at the turn of the tenth century and primarily associated with the Kingdom of Dyfed and later Deheubarth. It was named for its founder, Cadell ap Rhodri, a son of Rhodri Mawr of Gwynedd who conquered south-west Wales around 900 AD.
Many members of this family were influential in Welsh history, such as Hywel Dda, who allegedly codified Welsh law under his rule, and achieved the important title of King of the Britons, or Lord Rhys, Prince of Wales, who rebelled against Richard the Lionheart, and became one of the most powerful Welsh leaders of the Middle Ages.
