About Osmund of Sussex
Lived 700 – 800. Osmund of Sussex was an English and British monarch and sovereign.
Osmund (fl. ) was a King of Sussex, apparently reigning jointly with Oswald, Ælfwald, and Oslac.
According to the Anglo-Saxon Chronicle, version D, Osmund was reigning in Sussex when Archbishop Cuthbert died in 760, so his rule commenced before that event.
Osmund issued a charter, dated 762 in error for 765, as Osmundus.
Osmund also issued a charter dated 770 in which he is listed as Osmundus rex.
So Osmund's reign was from in or before 760 to between 770 and 772, as he witnessed a charter of Offa, King of Mercia, dated 772 as Osmund dux. Evidently he was demoted from king to ealdorman following Offa's conquest of Sussex.
