 Cynan Dindaethwy of Gwynedd, King of Gwynedd 1)Died 816 Notes: Cynan Dindaethwy (English: "Cynan of Dindaethwy") or Cynan ap Rhodri ("Cynan son of Rhodri") was a king of Gwynedd (reigned c. 798 - c. 816) in Wales of the Early Middle Ages. Cynan was the son of Rhodri Molwynog and ascended to the throne of Gwynedd upon the death of King Caradog ap Meirion in 798. His epithet refers to the commote of Dindaethwy in the cantref Rhosyr. Unlike later kings of Gwynedd, usually resident at Aberffraw in western Anglesey, Cynan maintained his court at Llanfaes on the southeastern coast.[1] Cynan's reign was marked by a destructive dynastic power struggle with a rival named Hywel, usually supposed to be his brother.
