Events
By place
Europe
- June 20 – Louis the Pious, Emperor of the Romans and King of the Franks, falls ill and dies at his hunting lodge, on an island in the Rhine, near the Ingelheim Imperial Palace in Francia, while suppressing a revolt. He proclaims his eldest son Lothair I as his successor as Emperor. Lothair tries to seize all the territories of his late grandfather Charlemagne. Louis' son by his second wife, Charles, 17, becomes King of the Franks, and joins with his half-brother Louis the German in resisting Lothair.
British Isles
- King Wigstan of Mercia in England, grandson of former ruler Wiglaf (d. 839), declines his kingship in preference of the religious life. He asks his widowed mother, Princess Ælfflæd, to act as regent. A nobleman of the line of the late king Beornred, named Berhtric, wishes to marry her but, as he is a relative, Wigstan refuses the match, and is murdered by followers of Berhtric at Wistow, Leicestershire. He is buried at Repton Abbey, and later revered as a saint. The Mercian throne is seized by Berhtric's father, Beorhtwulf.[1]
