The early history of the cantref is unclear. According to tradition, it was ruled by its eponymous founder
Rhufon, the third son of the first King of Gwynedd,
Cunedda, and his direct descendants from the year 445 until the year 540 when it was probably absorbed back into direct control of Gwynedd proper. It formed part of the territory of the
Deceangli during the
Roman occupation of Wales. Later, much of the land belonged to the bishops of
Bangor and
Llanelwy. By the
Middle Ages,
Denbigh was its capital. The cantref was given to the prince
Dafydd ap Gruffudd in 1277, then on his death five years later, it was given to
Henry de Lacy, 3rd Earl of Lincoln. It was merged with the cantref Rhos to form the
Lordship of Denbigh. Today most of the area now lies in
Denbighshire, with the western parts in
Conwy. == See also ==
