History & Significance

King Aethelberht II of East Anglia visited Offa's court and was beheaded — apparently on Offa's orders. The act was widely condemned; Aethelberht was venerated as a martyr and the Cathedral at Hereford is dedicated to him. East Anglia was absorbed into Mercia's orbit, ending its independence for a generation before the Danish invasions ended Mercian overlordship.
