Eadburh was the daughter of Offa of Mercia and his Queen, Cynethryth, and was the wife of Beorhtric of Wessex. She married Beorhtric in 789. According to Asser's account of the life of Alfred, Eadburh was something of an "éminence grise" behind her husband, and often demanded the executions or exile of those whom she saw as gaining too much of Beorhtric's affections.
