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 East Saxons, referred to as the Kingdom of Essex, was one of the seven traditional kingdoms of the Anglo-Saxon Heptarchy. It was founded in the 6th century and covered the territory later occupied by the counties of Essex, Middlesex, much of Hertfordshire and west Kent. The last king of Essex was Sigered of Essex, who in 825 ceded the kingdom to Ecgberht, King of Wessex. From 825 Essex was ruled as part of a south-eastern kingdom of Essex, Kent, Sussex and Surrey. It was not until 860 that Essex was fully integrated into the crown of Wessex.
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. 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.
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.
Æthelred was king of Mercia from 675 until 704. He was the son of Penda of Mercia and came to the throne in 675, when his brother, Wulfhere of Mercia, died from an illness. Within a year of his accession he invaded Kent, where his armies destroyed the city of Rochester. In 679 he defeated his brother-in-law, Ecgfrith of Northumbria, at the Battle of the Trent: the battle was a major setback for the Northumbrians, and effectively ended their military involvement in English affairs south of the Humber. It also permanently returned the Kingdom of Lindsey to Mercia's possession. However, Æthelred was unable to re-establish his predecessors' domination of southern Britain.
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.
Ine or Ini, was King of Wessex from 689 to 726. At Ine's accession, his kingdom dominated much of southern England. However, he was unable to retain the territorial gains of his predecessor, Cædwalla, who had expanded West Saxon territory substantially. By the end of Ine's reign, the kingdoms of Kent, Sussex, and Essex were no longer under West Saxon sway; however, Ine maintained control of what is now Hampshire, and consolidated and extended Wessex's territory in the western peninsula.
Middlesex was a county in southeast England. Its area was almost entirely within the wider urbanised area of London and mostly within the ceremonial county of Greater London, with small sections in neighbouring ceremonial counties. The county's boundaries largely followed three rivers: the Thames in the south, the Lea to the east and the Colne to the west. A line of hills formed the northern boundary with Hertfordshire.
The Kingdom of Lindsey or Linnuis was a lesser Anglo-Saxon kingdom, which was absorbed into Northumbria in the 7th century. The name Lindsey derives from the Old English toponym Lindesege, meaning "Isle of Lind". Lindum Colonia was the Roman name of the settlement which is now the City of Lincoln in Lincolnshire. Lindum was a Latinised form of a native Brittonic name which has been reconstructed as *Lindon.
Coenred was king of Mercia from 704 to 709. Mercia was an Anglo-Saxon kingdom in the English Midlands. He was a son of the Mercian king Wulfhere, whose brother Æthelred succeeded to the throne in 675 on Wulfhere's death. In 704, Æthelred abdicated in favour of Coenred to become a monk.
Ceolred was king of Mercia from 709 to 716.
Wiglaf was King of Mercia from 827 to 829 and again from 830 until his death. 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.
Wulfred was an Anglo-Saxon Archbishop of Canterbury in medieval England. Nothing is known of his life prior to 803, when he attended a church council, but he was probably a nobleman from Middlesex. He was elected archbishop in 805 and spent his time in office reforming the clergy of his cathedral. He also quarrelled with two consecutive Mercian kings – Coenwulf and Ceolwulf – over whether laymen or clergy should control monasteries. At one point, Wulfred travelled to Rome to consult with the papacy and was deposed from office for a number of years over the issue. After Coenwulf's death, relations were somewhat better with the new king Ceolwulf, but improved much more after Ceolwulf's subsequent deposition. The dispute about control of the monasteries was not fully settled until 838, after Wulfred's death. Wulfred was the first archbishop to place his portrait on the coinage he struck.
The Tribal Hidage is a list of thirty-five tribes that was compiled in Anglo-Saxon England some time between the 7th and 9th centuries. It includes a number of independent kingdoms and other smaller territories, and assigns a number of hides to each one. The list is headed by Mercia and consists almost exclusively of peoples who lived south of the Humber estuary and territories that surrounded the Mercian kingdom, some of which have never been satisfactorily identified by scholars. The value of 100,000 hides for Wessex is by far the largest: it has been suggested that this was a deliberate exaggeration.
Æthelwold, also known as Æthelwald or Æþelwald, was a 7th-century king of East Anglia, the long-lived Anglo-Saxon kingdom which today includes the English counties of Norfolk and Suffolk. He was a member of the Wuffingas dynasty, which ruled East Anglia from their regio at Rendlesham. The two Anglo-Saxon cemeteries at Sutton Hoo, the monastery at Iken, the East Anglian see at Dommoc and the emerging port of Ipswich were all in the vicinity of Rendlesham.
Seaxwulf was the founding abbot of the Mercian monastery of Medeshamstede, and an early medieval bishop of Mercia. Very little is known of him beyond these details, drawn from sources such as Bede's Ecclesiastical History. Some further information was written down in the 12th century at Peterborough Abbey, as Medeshamstede was known by that time. This suggests that he began his career as a nobleman, and that he may have had royal connections outside Mercia.
The Kingdom of the East Angles, informally known as the Kingdom of East Anglia, was a small independent kingdom of the Angles during the Anglo-Saxon period comprising what are now the English counties of Norfolk and Suffolk and perhaps the eastern part of the Fens, the area still known as East Anglia.
The Heptarchy were the seven petty kingdoms of Anglo-Saxon England that flourished from the Anglo-Saxon settlement of Britain in the 5th century until they were consolidated in the 8th century into the four kingdoms of East Anglia, Mercia, Northumbria, and Wessex.
