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".

Kings of GwyneddEdit

House of CuneddaEdit

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.

House of ManawEdit

House of AberffrawEdit

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.

House of DinefwrEdit

House of AberffrawEdit

  • Aeddan ap Blegywryd (1005–1018) (minor commote lord usurps Gwynedd from the Aberffraw dynasty)
