Rhodri Mawr
Quick Summary
Rhodri Mawr, meaning "Rhodri the Great," was a significant king of Gwynedd in Wales who reigned until his death in 878. He is noted for his strong resistance against Viking attacks and for expanding his dominion to include Powys and briefly parts of southwestern Wales.
The period following Rhodri's death saw Welsh kingdoms seeking allegiance with Wessex, leading to a formal submission to the English monarchy. His grandson, Hywel Dda (the Good), eventually unified Gwynedd, Powys, and Deheubarth, though he accepted the status of an under-king to the king of Wessex. This era was marked by attempts to unify Welsh kingdoms and resistance against Anglo-Saxon and Norse influence.12
