Saxon ruler of England, 839-856.
Æthelwulf was the son of King Egbert of Wessex, who was the first to control all of England, and is generally considered England's first king. Egbert ceded the country to Æthelwulf on his death in 839. Æthelwulf later gave the smaller kingdoms of Kent, Essex, and Sussex to his son Athelstan. In 840, he fought the Danes at Charmouth. In 851, Æthelwulf and his son Æthelbald were victorious against the Mercians at Ockley.
