Æthelbert, d. 865, king of Wessex (860–65), son of Æthelwulf. After the death of his father in 858 he ruled Kent, Surrey, Sussex, and Essex, and he reunited them with Wessex when in 860 he succeeded his brother Æthelbald in that kingdom. Throughout his reign the attacks of the Danes were severe, and they continued through the reign of his brother and successor, Æthelred.
