Beorhtwulf's kingship began auspiciously. In the battle of Catill or Cyfeiliog, he killed
King Merfyn Frych of
Gwynedd Berkshire appears to have passed out of Mercian hands and become a part of the kingdom of Wessex at some point during the late 840s. In 844
Ceolred, the
bishop of Leicester, granted Beorhtwulf an estate at
Pangbourne, in Berkshire, so the area was still in Mercian hands at that date.
Asser, writing in about 893, believed that King
Alfred the Great was born between 847 and 849 at
Wantage in Berkshire. The implication is that Berkshire had previously come under the control of Wessex, though it is also possible the territory was divided between the two kingdoms, possibly even before Beorhtwulf's accession. Whatever the nature of the change, there is no record of how it occurred. It appears that the Mercian
ealdorman Æthelwulf remained in office afterwards, implying a peaceful transition. This is not an isolated case; there are other charters that show Mercian kings of the time disputing property with the church, such as a charter of 849 in which Beorhtwulf received a lease on land from the bishop of Worcester, and promised in return that he would be "more firmly the friend of the bishop and his community" and, in the words of historian
Patrick Wormald, "would not rob them in future". Wormald suggests that this ruthless behaviour may be explained by the fact that landed estates were becoming harder to find, as so much land had been granted to monasteries. The problem had been mentioned over a century before by
Bede, who in a letter to
Egbert, the Archbishop of York, had complained of "a complete lack of places where the sons of nobles and of veteran thegns can receive an estate". Beorhtwulf's concession of wrongdoing suggests that he could not rely on his nobles to support him in such a disagreement, and may indicate that his hold on the throne was insecure.
End In 851, a Viking army landed at
Thanet, then still an island, and over-wintered there. A second Viking force of 350 ships is reported by the
Anglo-Saxon Chronicle to have stormed
Canterbury and London, and to have "put to flight Beorhtwulf, king of Mercia, with his army". The Vikings were defeated by Æthelwulf and his sons,
Æthelstan and
Æthelbald, but the economic impact appears to have been significant, as Mercian coinage in London was very limited after 851. No surviving contemporary source records Beorhtwulf's death, but according to the
Anglo-Saxon Chronicle his successor, Burgred, reigned for twenty-two years and was driven from his throne by the Vikings in 874, implying that Beorhtwulf died in 852. From Burgred's charters it is known that his reign began before 25 July 852. == Family ==
