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.
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.
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.
Æthelberht was the King of Wessex from 860 until his death in 865. He was the third son of King Æthelwulf by his first wife, Osburh. Æthelberht was first recorded as a witness to a charter in 854. The following year Æthelwulf went on pilgrimage to Rome and appointed his oldest surviving son, Æthelbald, as king of Wessex while Æthelberht became king of the recently conquered territory of Kent. Æthelberht may have surrendered his position to his father when he returned from pilgrimage, but resumed the south-eastern kingship when his father died in 858.
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.
Wulfhere or Wulfar was King of Mercia from 658 until 675 AD. He was the first Christian king of all of Mercia, though it is not known when or how he converted from Anglo-Saxon paganism. His accession marked the end of Oswiu of Northumbria's overlordship of southern England, and Wulfhere extended his influence over much of that region. His campaigns against the West Saxons led to Mercian control of much of the Thames valley. He conquered the Isle of Wight and the Meon valley and gave them to King Æthelwealh of the South Saxons. He also had influence in Surrey, Essex, and Kent. He married Eormenhild, the daughter of King Eorcenberht of Kent.
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.
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 ended Mercian Supremacy over the southern kingdoms of Anglo-Saxon England and established West Saxon dominance in southern England.
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.
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.
Cædwalla was the King of Wessex from approximately 685 until he abdicated in 688. His name is derived from the Welsh Cadwallon. He was exiled from Wessex as a youth and during this period gathered forces and attacked the South Saxons, killing their king, Æthelwealh, in what is now Sussex. Cædwalla was unable to hold the South Saxon territory, however, and was driven out by Æthelwealh's ealdormen. In either 685 or 686, he became King of Wessex. He may have been involved in suppressing rival dynasties at this time, as an early source records that Wessex was ruled by underkings until Cædwalla.
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.
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 Haestingas, Heastingas or Hæstingas were one of the tribes of Anglo-Saxon Britain. Not very much is known about them. They settled in what became East Sussex sometime before the end of the 8th century. A 12th-century source suggested that they were conquered by Offa of Mercia, in 771. They were also recorded in the Anglo-Saxon Chronicle (ASC) as being an autonomous grouping as late as the 11th century.
Ealhstan was a medieval Bishop of Sherborne.
The Kingdom of the East Angles, today known as the Kingdom of East Anglia, was a small independent kingdom of the Angles comprising what are now the English counties of Norfolk and Suffolk and perhaps the eastern part of the Fens. The kingdom formed in the 6th century in the wake of the Anglo-Saxon settlement of Britain. It was ruled by the Wuffingas dynasty in the 7th and 8th centuries, but fell to Mercia in 794, and was conquered by the Danes in 869, to form part of the Danelaw. It was conquered by Edward the Elder and incorporated into the Kingdom of Wessex in 918.
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.
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.
