=== Llwelyn ap Seisyll Seized Throne in 1018 ... ===
Cynan ap Hywel ruled Gwynedd and Deheubarth until 1005. The circumstances by which he was succeeded by Aeddan ap Blegywryd have not survived. Since Aeddan was not in the direct line of succession, one theory is that Aeddan may have seized the throne by force. In any case, Aeddan ruled until 1018, when he and his four sons were killed in battle by Llwelyn ap Seisyll. According to the Brut y Tywysogion, Llwelyn’s reign was a time of prosperity, though it only lasted until his death in 1023. At least one source attributes his assassination to Madog Min, the Bishop of Bangor.
