The description of King Sigeberht of Wessex being deposed by Cynewulf is notably fuller than earlier entries in the Anglo-Saxon Chronicle.

Sigeberht had succeeded his distant relative Cuthred in 756, but was then accused of acting unjustly.

He is removed from power by a council of nobles, but given control of Hampshire.

There, he is accused of murder, driven out and ultimately killed.

It is possible that this happened under the influence of Æthelbald of Mercia.

His brother Cyneheard is also driven out, but will return in 786 to kill Sigeberht's successor Cynewulf.
