Bleddyn ap Cynfyn
Bleddyn ap Cynfyn (died 1075) was a Welsh prince who ruled as king of Gwynedd and Powys from 1063 until his assassination, initially co-ruling with his brother Rhiwallon ap Cynfyn until the latter's death in 1070.[1][2] The son of Cynfyn ap Gwerstan and Angharad (widow of Llywelyn ap Seisyll and mother of the previous high king Gruffudd ap Llywelyn), Bleddyn was installed by the English earls Harold Godwinson and Tostig after he and Rhiwallon defeated Gruffudd's sons Caradog and Maredudd in battle, ending their bid for power.[2][1] During his reign, Bleddyn maintained peace with England, avoiding recorded conflicts, and was renowned for his justice, liberality, and enactment of laws and regulations that echoed the ancient codes of Hywel Dda, earning him widespread lamentation upon his death at the hands of Rhys ab Owain of Deheubarth and Ystrad Tywi nobles.[2][1] His rule marked a period of stability in northern and eastern Wales following the turbulent dominance of Gruffudd ap Llywelyn, with Bleddyn's descendants founding the second dynasty of Powys.[2]
