Name the King of Wessex from 839 to 858 whose father, King Egbert, defeated Beornwulf of Mercia and who himself led the Battle of Aclea between the West Saxons and the Danish Vikings?
Battle of Aclea The Battle of Aclea occurred in 851 between the West Saxons led by Æthelwulf, King of Wessex and the Danish Vikings. It resulted in a West Saxon victory.
Baldred of Kent Baldred was king of Kent, from 823 until 826 or 827. Ceolwulf I, king of Mercia, had ruled Kent directly, but in 823 he was deposed by Beornwulf, and at about the same time moneyers at Canterbury started issuing coins in the name of Baldred, king of Kent. It is uncertain whether he was independent or a Mercian under-king. In 826 or 827 he was expelled by Æthelwulf, son of King Egbert of Wessex, and Kent was ruled directly by Wessex thereafter.
