This is a list of the rulers of the Kingdom of Gwynedd. Many of them were also acclaimed "King of the Britons" or "Prince of Wales".
With Hywel's death, all male descendants of Maelgwn Gwynedd have expired. Merfyn the Freckled succeeds through his mother Esyllt, eldest daughter of Cynan Dindaethwy and niece of Hywel ap Rhodri Molwynog.
The warfare among the sons of Rhodri meant that the descendants of Anarawd became considered a separate house – called the House of Aberffraw from their principal seat – from the junior branches in Deheubarth and elsewhere.
