Беортвульф, король Мерсии (839/840–852)

9th century King of the Mercians

Beorhtwulf (, meaning "bright wolf"; also spelled Berhtwulf; died 852) was King of Mercia, a kingdom of Anglo Saxon England, from 839 or 840 to 852. His ancestry is unknown, though he may have been connected to Beornwulf, who ruled Mercia in the 820s. Almost no coins were issued by Beorhtwulf's predecessor, Wiglaf, but a Mercian coinage was restarted by Beorhtwulf early in his reign, initially with strong similarities to the coins of Æthelwulf of Wessex, and later with independent designs. The Vikings attacked within a year or two of Beorhtwulf's accession: the province of Lindsey was raided in 841, and London, a key centre of Mercian commerce, was attacked the following year. Another Viking assault on London in 851 "put Beorhtwulf to flight", according to the Anglo Saxon Chronicle; the Vikings were subsequently defeated by Æthelwulf. This raid may have had a significant economic impact on Mercia, as London coinage is much reduced after 851. Berkshire appears to have passed from Mercian to West Saxon control during Beorhtwulf's reign. The Welsh are recorded to have rebelled against Beorhtwulf's successor, Burgred, shortly after Beorhtwulf's death, suggesting that Beorhtwulf had been their overlord. Charters from Beorthwulf's reign show a strained relationship with the church, as Beorhtwulf seized land and subsequently returned it. Beorhtwulf and his wife, Sæthryth, may have had two sons, Beorhtfrith and Beorhtric. Beorhtric is known from witnessing his father's charters, but he ceased to do so before the end of Beorhtwulf's reign. Beorhtfrith appears in later sources which describe his murder of Wigstan, the grandson of Wiglaf, in a dispute over Beorhtfrith's plan to marry Wigstan's widowed mother Ælfflæd. Beorhtwulf's death is not recorded in any surviving sources, but it is thought that he died in 852.

For most of the 8th century, Mercia was the dominant Anglo Saxon kingdom. Mercian influence in the south eastern kingdoms of Kent, East Anglia, and Essex continued into the early 820s under Coenwulf of Mercia. However, Coenwulf's death in 821 marked the beginning of a period in which Mercia suffered from dynastic conflicts and military defeats that redrew the political map of England. Four (possibly five) kings, from what appear to be four different kin groups, ruled Mercia throughout the next six years. Little genealogical information about these kings has survived, but since Anglo Saxon names often included initial elements common to most or all members of a family, historians have suggested that kin groups in this period can be reconstructed on the basis of the similarity of their names. Three competing kin groups are recognizable in the charters and regnal lists of the time: the C, Wig and B groups. The C group, which included the brothers Coenwulf, Cuthred of Kent, and Ceolwulf I, was dominant in the period following the deaths of Offa of Mercia and his son Ecgfrith in 796. Ceolwulf was deposed in 823 by Beornwulf, perhaps the first of the B group, who was killed fighting against the East Anglians in 826. He was followed by Ludeca, not obviously linked to any of the three groups, who was killed in battle the following year. After Ludeca's death, the first of the Wig family came to power: Wiglaf, who died in 839 or 840. Beorhtwulf, who succeeded to the throne that year, is likely to have come from the B group, which may also have included the ill fated Beornred who "held [power] a little while and unhappily" after the murder of King Æthelbald in 757. An alternative model of Mercian succession is that a number of kin groups may have competed for the succession. The sub kingdoms of the Hwicce, the Tomsæte, and the unidentified Gaini are examples of such power bases. Marriage alliances could also have played a part. Competing magnates—those called in charters "dux" or "princeps" (that is, leaders)—may have brought the kings to power. In this model, the Mercian kings are little more than leading noblemen. Charters dating from Beorhtwulf's reign have survived; these were documents which granted land to followers or to churchmen and were witnessed by the kings who had the authority to grant the land. A charter might record the names of both a subject king and his overlord on the witness list appended to the grant. Such a witness list can be seen on the Ismere Diploma, for example, where Æthelric, son of king Oshere of the Hwicce, is described as a "subregulus", or subking, of Æthelbald of Mercia.

It is possible that Beorhtwulf is the same person as the Beorhtwulf who witnessed a charter of Wiglaf's in 836. If so, this is Beorhtwulf's first appearance in the historical record. His accession to the throne of Mercia is usually thought to have occurred in about 840. Almost no Mercian coins are known from the 830s, after Wiglaf regained Mercia from Egbert of Wessex. Beorhtwulf restarted a Mercian coinage early in his reign, and the extended gap in the 830s has led to the suggestion that Wiglaf's second reign was as a client king of Egbert's, without permission to mint his own coinage. Beorhtwulf's coinage would then indicate his independence of Mercia. However, it is more usually thought that Wiglaf took Mercia back by force. An alternative explanation for Beorhtwulf's revival of the coinage is that it was part of a plan for economic regeneration in the face of the Viking attacks. The Viking threat may also account for the evident cooperation in matters of currency between Mercia and Wessex which began in Beorhtwulf's reign and lasted until the end of the independent Mercian kingdom on the death of King Ceolwulf II in the years around 880. The earliest of Beorhtwulf's coins were issued in 841–842, and can be identified as the work of a Rochester die cutter who also produced coins early in the reign of Æthelwulf of Wessex. After ten years without any coinage, Beorhtwulf would have had to go outside Mercia to find skilled die cutters, and Rochester was the closest mint. Hence the link to Rochester probably does not indicate that the coins were minted there; it is more likely that they were produced in London, which was under Mercian control. Subsequent coins of Beorhtwulf's are very similar to Æthelwulf's. One coin combines a portrait of Beorhtwulf on the reverse side with a design used by Æthelwulf on the obverse; this has been interpreted as indicating an alliance between the two kingdoms, but it is more likely to have been the work of a forger or an illiterate moneyer reusing the design of a coin of Æthelwulf's. A different coinage appears later in the 840s, and was probably ended by the Viking attacks of 850–851. There are also coins without portraits that are likely to have been produced at the very end of Beorhtwulf's reign.

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.

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.

Beorhtwulf was married to Sæthryth, apparently a figure of some importance in her own right as she witnessed all of his charters between 840 and 849, after which she disappears from the record. Beorhtwulf is said to have had two sons, Beorhtfrith and Beorhtric. Beorhtric is known from witnessing his father's charters, but he ceased to do so before the end of Beorhtwulf's reign. The story of Beorhtwulf's other known son, Beorhtfrith, is told in the Passio sancti Wigstani, which may include material from a late 9th century source, with some corroboration in the chronicle of John of Worcester. Beorhtfrith wished to marry the royal heiress Ælfflæd, King Ceolwulf's daughter, widow of Wiglaf's son Wigmund and mother of Wigstan. Wigstan refused to allow the marriage, since Beorhtfrith was a kinsman of Wigmund's and was also Wigstan's godfather. In revenge, Beorhtfrith murdered Wigstan, who was subsequently venerated as a saint. The story, though of late origin, is regarded as plausible by modern historians.
