Coenwulf was succeeded by his brother, Ceolwulf; a post-Conquest legend claims that his son Cynehelm was murdered to gain the succession. Within two years Ceolwulf had been deposed, and the kingship passed permanently out of Coenwulf's family. Coenwulf was the last king of Mercia to exercise substantial dominance over other Anglo-Saxon kingdoms. Within a decade of his death, the rise of Wessex had begun under King Egbert, and Mercia never recovered its former position of power.
