AETHELBERT, king of the West Saxons, succeeded to the under-kingdom of Kent during the lifetime of his father, Aethelwulf, and retained it until the death of his elder brother, Aethelbald, in 86o, when he became sole king of Wessex and Kent till his death in 865. His reign was marked by two serious attacks by the Danes, who were repelled in 86o by the levies of Hampshire and Berkshire, though not before they had sacked Winchester, while in 865 they ravaged Kent after agreeing to take money for peace. Aethelbert was buried at Sherborne.
