History

Like many Mercians of the period very little is known about Wigstan. He was the son of Wigmund and Ælfflæd, both the offspring of Mercian kings, Wiglaf and Ceolwulf I respectively. Wigmund, according to the Croyland Chronicle, died of dysentery before his father King Wiglaf, making Wigstan heir to the kingdom of Mercia. However, when Wiglaf died c.839, Wigstan declined the kingship preferring religious life and monastic orders instead. Beorhtwulf, possibly Wigstan's great-uncle, became king instead. William of Malmesbury claims that Beorhtwulf's son, Beorhtfrith, wished to marry Wigstan's widowed mother, Ælfflæd, but Wigstan forbade the union as they were too closely related. As revenge Beorhtfrith went to visit the young King ostensibly in peace but, when the two greeted each other, he struck Wigstan on the head with the shaft of his dagger and his servant ran him through with his sword.
