Beonna of East Anglia Beonna (also known as Beorna) was King of East Anglia from 749. He is notable for being the first East Anglian king whose coinage included both the ruler's name and his title. The end-date of Beonna's reign is not known, but may have been around 760. It is thought that he shared the kingdom with another ruler called Alberht and possibly with a third man, named Hun. Not all experts agree with these regnal dates, or the nature of his kingship: it has been suggested that he may have ruled alone (and free of Mercian domination) from around 758.
