Hyfaidd, King of Dyfed
(c.815-893)
(Latin: Hubaetus; English: Hubert)

Hyfaidd was the son of Princess Tangwystl, the daughter of King Owain ap Maredudd of Dyfed, by a lowborn Welshman named Bledrig. He inherited the Throne in the mid-9th century, possibly from his father. Hyfaidd was known as something of a tyrant who often plundered the Cathedral of Mynyw (St. Davids) and expelled the boshop and his monks. However, Hyfaidd also had his own oppressor in the person of King Anarawd of Gwynedd and his brothers. In order to stop Anarawd's conquests at the Dyfed border, Hyfaidd submitted to the overlordship of King Alfred the Great of England in the 880s, as described by Bishop Asser, the latter's biographer. Hyfaidd died in 893 and was succeeded by his son, Rhodri.
