The Battle of Ellendun or Battle of Wroughton was fought between Ecgberht of Wessex and Beornwulf of Mercia in September 825. Sir Frank Stenton described it as "one of the most decisive battles of English history". It effectively established West Saxon dominance in southern England.

During the 8th century and early 9th centuries, the kings of Mercia exercised a fluctuating hegemony over the kingdoms of south-eastern England, imposing their overlordship and at times exercising direct rule. While Wessex had at times been obliged to recognise the overlordship of Æthelbald of Mercia, it appears to have escaped the dominance of the Mercians thereafter and was certainly not subject to the more intrusive forms of Mercian control imposed on other kingdoms.
Ecgberht's father Ealhmund had been king of Kent in the 780s, which had brought his family into conflict with the ambitions of Offa of Mercia, who sought to impose direct rule on Kent. After his father's death, Ecgberht was driven from England into exile by Offa, with the co-operation of Beorhtric of Wessex and his accession to the throne of Wessex on Beorhtric's death in 802 was immediately followed by a violent clash with Mercia. However, the available sources reveal no further conflict between the two kingdoms before 825.
Beornwulf seized the Mercian throne from Ceolwulf, who had in 821 succeeded on the death of his brother, the long-reigning and powerful Coenwulf. His attack on Wessex two years later may have been part of an effort to consolidate his own authority and reassert that of Mercia after this upheaval.
Beornwulf may also have been seeking to take advantage of Ecgberht's preoccupation with warfare against the Britons of Cornwall. Ecgberht had devastated Cornish territory in 815 and in the autumn of 825 he was again campaigning against the Britons, at Gafulford.
The Battle of Ellendun is thought to have taken place south of Swindon, in Wiltshire, but the exact site has not been determined. William Camden, in his 1610 gazetteer A Chronological description of the most flourishing Kingdomes, England, Scotland, and Ireland, suggests that the battle took place close to Wilton, just to the west of Salisbury. [1] Charles Oman used geographical information and contemporary boundaries as evidence to suggest the battle occurred at Wroughton, [2] which is 4 miles (6 km) south of Swindon. T. Spicer has suggested the battle took place on the grounds of what is now Lydiard Park, in Swindon.

Ecgberht's victory permanently transformed the political situation in south-eastern England. The king at once sent his son Æthelwulf with an army into the south-east. The West Saxons succeeded in conquering Sussex (hitherto under direct Mercian rule), Kent, and Essex, which had been governed by under-kings who had accepted Mercian overlordship. All of these territories were annexed to Wessex, roughly doubling the kingdom's size.
Meanwhile, Beornwulf's defeat emboldened the East Angles to revolt against Mercian rule and reassert their independence, in alliance with Wessex. Beornwulf fought the East Angles, but was defeated and killed. His successor Ludeca met the same fate the following year and East Anglian independence was successfully re-established.
Ecgberht's power peaked in 829, when he occupied Mercia and secured recognition of his supremacy by the Northumbrians, making him temporarily the overlord of all England. Mercian independence was restored in the following year by Wiglaf, who achieved a significant recovery of Mercian prestige and was even able to extend his power over Berkshire. The independence of East Anglia and the West Saxon conquest of the south-east proved irreversible and Mercia never regained the primacy it had enjoyed in the century before Ellendun.
Bretwalda is an Old English word. The first record comes from the late 9th-century Anglo-Saxon Chronicle. It is given to some of the rulers of Anglo-Saxon kingdoms from the 5th century onwards who had achieved overlordship of some or all of the other Anglo-Saxon kingdoms. It is unclear whether the word dates back to the 5th century and was used by the kings themselves or whether it is a later, 9th-century, invention. The term bretwalda also appears in a 10th-century charter of Æthelstan. The literal meaning of the word is disputed and may translate to either 'wide-ruler' or 'Britain-ruler'.
The Kingdom of the West Saxons, also known as the Kingdom of Wessex, was an Anglo-Saxon kingdom in the south of Great Britain, from around 519 until Alfred the Great declared himself as King of the Anglo-Saxons in 886.
Year 825 (DCCCXXV) was a common year starting on Sunday of the Julian calendar.
Mercia was one of the three main Anglic kingdoms founded after Sub-Roman Britain was settled by Anglo-Saxons in an era called the Heptarchy. It was centred on the River Trent and its tributaries, in a region now known as the Midlands of England.
Offa was King of Mercia, a kingdom of Anglo-Saxon England, from 757 until his death in 796. The son of Thingfrith and a descendant of Eowa, Offa came to the throne after a period of civil war following the assassination of Æthelbald. Offa defeated the other claimant, Beornred. In the early years of Offa's reign, it is likely that he consolidated his control of Midland peoples such as the Hwicce and the Magonsæte. Taking advantage of instability in the kingdom of Kent to establish himself as overlord, Offa also controlled Sussex by 771, though his authority did not remain unchallenged in either territory. In the 780s he extended Mercian Supremacy over most of southern England, allying with Beorhtric of Wessex, who married Offa's daughter Eadburh, and regained complete control of the southeast. He also became the overlord of East Anglia and had King Æthelberht II of East Anglia beheaded in 794, perhaps for rebelling against him.
Ecgberht, also spelled Egbert, Ecgbert, Ecgbriht, Ecgbeorht, and Ecbert, was King of Wessex from 802 until his death in 839. His father was King Ealhmund of Kent. In the 780s, Ecgberht was forced into exile to Charlemagne's court in the Frankish Empire by the kings Offa of Mercia and Beorhtric of Wessex, but on Beorhtric's death in 802, Ecgberht returned and took the throne.
Æthelwulf was King of Wessex from 839 to 858. In 825, his father, King Ecgberht, defeated King Beornwulf of Mercia, ending a long Mercian dominance over Anglo-Saxon England south of the Humber. Ecgberht sent Æthelwulf with an army to Kent, where he expelled the Mercian sub-king and was himself appointed sub-king. After 830, Ecgberht maintained good relations with Mercia, and this was continued by Æthelwulf when he became king in 839, the first son to succeed his father as West Saxon king since 641.
Æthelbald was the King of Mercia, in what is now the English Midlands from 716 until he was killed in 757. Æthelbald was the son of Alweo and thus a grandson of King Eowa. Æthelbald came to the throne after the death of his cousin, King Ceolred, who had driven him into exile. During his long reign, Mercia became the dominant kingdom of the Anglo-Saxons, and recovered the position of pre-eminence it had enjoyed during the strong reigns of Mercian kings Penda and Wulfhere between about 628 and 675.
Coenwulf was the king of Mercia from December 796 until his death in 821. He was a descendant of King Pybba, who ruled Mercia in the early 7th century. He succeeded Ecgfrith, the son of Offa; Ecgfrith only reigned for five months, and Coenwulf ascended the throne in the same year that Offa died. In the early years of Coenwulf's reign he had to deal with a revolt in Kent, which had been under Offa's control. Eadberht Præn returned from exile in Francia to claim the Kentish throne, and Coenwulf was forced to wait for papal support before he could intervene. When Pope Leo III agreed to anathematise Eadberht, Coenwulf invaded and retook the kingdom; Eadberht was taken prisoner, was blinded, and had his hands cut off. Coenwulf also appears to have lost control of the kingdom of East Anglia during the early part of his reign, as an independent coinage appears under King Eadwald. Coenwulf's coinage reappears in 805, indicating that the kingdom was again under Mercian control. Several campaigns of Coenwulf's against the Welsh are recorded, but only one conflict with Northumbria, in 801, though it is likely that Coenwulf continued to support the opponents of the Northumbrian king Eardwulf.
Ealhmund was King of Kent in 784. He was probably the father of King Ecgberht who was King of Wessex from 802, and who conquered Kent in the 820s. Ecgberht was the grandfather of King Alfred the Great.
The Kingdom of the Kentish, today referred to as the Kingdom of Kent, was an early medieval kingdom in what is now South East England. It existed from either the fifth or the sixth century AD until it was fully absorbed into the Kingdom of Wessex in the mid-9th century and later into the Kingdom of England in the early 10th century.
Beorhtric was the King of Wessex from 786 to 802, succeeding Cynewulf. During his rule, however, his wife and father-in-law had most of the power.
Beornwulf; Old English for "Bear Wolf"; was the King of Mercia, a kingdom of Anglo-Saxon England, from 823 until his death in 826. His short reign saw the collapse of Mercia's supremacy over the other kingdoms of the Anglo-Saxon Heptarchy.
Wiglaf was King of Mercia from 827 to 829 and again from 830 until his death in 839. His ancestry is uncertain: the 820s were a period of dynastic conflict within Mercia and the genealogy of several of the kings of this time is unknown. Wigstan, his grandson, was later recorded as a descendant of Penda of Mercia, so it is possible that Wiglaf was descended from Penda, one of the most powerful seventh-century kings of Mercia.
Beorhtwulf 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.
The Battle of Otford was fought in 776 between the Mercians, led by Offa of Mercia, and the Jutes of Kent. The battle took place at Otford, in the modern English county of Kent.
Sigered of Essex was the last king of Essex from 798 to 825. The son of Sigeric of Essex, Sigered became king when his father abdicated the throne.
Events from the 9th century in England.
The Mercian Supremacy was the period of Anglo-Saxon history between c. 716 and c. 825, when the kingdom of Mercia dominated the Anglo-Saxon Heptarchy in England. Sir Frank Stenton apparently coined the phrase, arguing that Offa of Mercia, who ruled 757–796, effectively achieved the unification of England south of the Humber estuary. Scholastic opinion on the relationship between the kingdoms of Wessex and Mercia at this time remains divided.
