Ceolwulf I of Mercia
Ceolwulf I was King of Mercia, East Anglia and Kent, from 821 to 823. He was the brother of Coenwulf, his predecessor, and was deposed by Beornwulf. William of Malmesbury declared that, after Cœnwulf: "the kingdom of the Mercians declining, and if I may use the expression, nearly lifeless, produced nothing worthy of historical commemoration." Actually, Mercia did have a moment of glory that William was unaware of. Indicating the year 822, the "Annales Cambriae" states: "The fortress of Degannwy (in Gwynedd) is destroyed by the Saxons and they took the kingdom of Powys into their  own control." A later charter depicts a disturbed state of affairs during Ceolwulf's reign: "After the death of Cœnwulf, king of the Mercians, many disagreements and innumerable disputes arose among leading persons of every kind – kings, bishops, and ministers of the churches of God – concerning all manner of secular affairs". In 823, sometime after 26 May, on which date he granted land to Archbishop Wulfred in exchange for a gold and silver vessel, Ceolwulf was overthrown. His replacement was Beornwulf, whose pedigree is not known. Ceolwulf ruled Kent directly – in his two charters, he is styled as "King of  the Mercians and of the men of Kent". Family. Ceolwulf was the son of Cuthberht of Mercia and the brother of Coenwulf of Mercia (d.821) and Cuthred of Kent (d.807). Coenwulf ruled as king of Mercia from 796 until his death in 821. In 798 Coenwulf installed his brother Cuthred as king of Kent in 798. Cuthred ruled there until his death in 807, after which Kent reverted back to Mercia. Upon Coenwulf's death in 821 he was succeeded by Ceolwulf. The name of Ceolwulf's wife is not recorded, however, they had one known child, a daughter: According  to a tradition preserved at Evesham, Ceolwulf's daughter Ælfflæd married Wigmund, the son of Wiglaf, King of Mercia 827-839. Wiglaf was succeeded by Beorhtwulf and his son Berhtfrith sought to marry King Wigmund's widow so that he could become king. This was opposed by Wigstan, the son of Wigmund and Ælfflæd, and Berhtfrith slew Wigstan in 849. However, there is no record outside this Evesham tradition that Wigmund was ever king. Alfred Smyth suggests that Ceolwulf II, who became king following the Viking expulsion of King Burgred in 874, may have been another son of Ælfflæd, and  thus a grandson of Ceolwulf I.
