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 Beorhtwulf'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.

Background and sources

For most of the 8th century, Mercia was the dominant Anglo-Saxon kingdom.Hunter Blair, Roman Britain, p. 274. Mercian influence in the south-eastern kingdoms of Kent, East Anglia, and Essex continued into the early 820s under Coenwulf of Mercia.Yorke, Kings and Kingdoms, p. 121. 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.Kirby, Earliest English Kings, p. 185 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.Simon Keynes, "Mercia and Wessex in the Ninth Century", pp. 314–323; Yorke, Kings and Kingdoms, pp. 119–122 & table 14. Baldred of Kent (ruled 821?–825) may have been a member of the B family. Finally, a possible East Anglian link, with King Beonna of East Anglia and the Beodric for whom Bury St Edmunds was originally named, has been mooted;

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.

An important source for the period is the Anglo-Saxon Chronicle, a collection of annals in Old English narrating the history of the Anglo-Saxons. The Chronicle was a West Saxon production, however, and is sometimes thought to be biased in favour of Wessex.Campbell, Anglo-Saxon State, p. 144. 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.Hunter Blair, Roman Britain, pp. 14–15.Campbell, The Anglo-Saxons, pp. 95–98. 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.Whitelock, English Historical Documents, 67, pp. 453–454.

Accession and coinage 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.Prosopography of Anglo-Saxon England, "Beorhtwulf 3 (Male)"; Keynes, "Mercia and Wessex in the Ninth Century", p. 317. His accession to the throne of Mercia is usually thought to have occurred in about 840. The date is not given directly in any of the primary sources, but it is known from regnal lists that he succeeded Wiglaf as king. Historian D. P. Kirby suggests that Wiglaf's death occurred in 839, basing this date on the known chronology of the reigns of Beorhtwulf and Burgred, the next two Mercian kings. It is possible that Wigmund, the son of Wiglaf, was king briefly between Wiglaf and Beorhtwulf. The evidence for this possibility comes only from a later tradition concerning Wigmund's son, Wigstan, so it is uncertain whether he actually did so.Kirby, Earliest English Kings, p. 194.

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.Williams, "Mercian coinage", pp. 223–226.

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.Blackburn & Grierson, Medieval European Coinage, pp. 292–293.Kirby, Earliest English Kings, p. 195.

Reign

Beorhtwulf's kingship began auspiciously. In the battle of CatillThe Annals of Wales (B text), p. 10. or Cyfeiliog,Chronicle of the Princes, entry 838. he killed King Merfyn Frych of Gwynedd and later sources imply (see below) that he was able to subjugate the northern Welsh after this.

However, the Anglo-Saxon Chronicle records Viking raids in 841 against the south and east coasts of Britain, including the Mercian province of Lindsey, centred on modern Lincoln. The city of London, chief centre of Mercia's trade, was attacked the following year. The Chronicle states that there was "great slaughter" in London, and large coin hoards were buried in the city at this time.Swanton, Anglo-Saxon Chronicle, pp. 62–65, Ms. A, s.a. 838 & 839, Ms. E. s.a. 837 & 839; Cowie, "Mercian London", pp. 207–208.

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.Zaluckyj & Zaluckyj, "Decline", pp. 238–239.Keynes & Lapidge, Alfred the Great, p. 228, note 2; Kirby, p. 195; Williams, pp. 65–66.Stenton, Anglo-Saxon England, p. 234.Whitelock, English Historical Documents, 87, pp. 480–481.

In 853, not long after Beorhtwulf's death, the Welsh rebelled against Burgred and were subdued by an alliance between Burgred and Æthelwulf.Kirby, Earliest English Kings, pp. 192, 195.
