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'.
Rædwald, also written as Raedwald or Redwald, was a king of East Anglia, an Anglo-Saxon kingdom which included the present-day English counties of Norfolk and Suffolk. He was the son of Tytila of East Anglia and a member of the Wuffingas dynasty, who were the first kings of the East Angles. Details about Rædwald's reign are scarce, primarily because the Viking invasions of the 9th century destroyed the monasteries in East Anglia where many documents would have been kept. Rædwald reigned from about 599 until his death around 624, initially under the overlordship of Æthelberht of Kent. In 616, as a result of fighting the Battle of the River Idle and defeating Æthelfrith of Northumbria, he was able to install Edwin, who was acquiescent to his authority, as the new king of Northumbria. During the battle, both Æthelfrith and Rædwald's son, Rægenhere, were killed.
Northumbria was an early medieval Anglo-Saxon kingdom in what is now Northern England and south-east Scotland.
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.
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.
Penda was a 7th-century king of Mercia, the Anglo-Saxon kingdom in what is today the Midlands. A pagan at a time when Christianity was taking hold in many of the Anglo-Saxon kingdoms, Penda took over the Severn Valley in 628 following the Battle of Cirencester before participating in the defeat of the powerful Northumbrian king Edwin at the Battle of Hatfield Chase in 633.
Bernicia was originally the Brittonic Celtic kingdom of Bryneich from the late 4th century and later the Anglo-Saxon kingdom of 'Bernicia' established by Anglian conquerors of the late 6th century in what is now southeastern Scotland and North East England.
Ermine Street is a major Roman road in England that ran from London (Londinium) to Lincoln and York (Eboracum). The Old English name was Earninga Strǣt (1012), named after a tribe called the Earningas, who inhabited a district later known as Armingford Hundred, around Arrington, Cambridgeshire, and Royston, Hertfordshire. "Armingford", and "Arrington" share the same Old English origin. The original Celtic and Roman names for the route remain unknown. It is also known as the Old North Road from London to where it joins the A1 Great North Road near Godmanchester.
The Battle of the Winwaed was fought on 15 November 655 between King Penda of Mercia and Oswiu of Bernicia, ending in the Mercians' defeat and Penda's death. According to Bede, the battle marked the effective demise of Anglo-Saxon paganism.
Lincolnshire, England derived from the merging of the territory of the ancient Kingdom of Lindsey with that controlled by the Danelaw borough Stamford. For some time the entire county was called 'Lindsey', and it is recorded as such in the Domesday Book. Later, Lindsey was applied to only the northern core, around Lincoln; it was defined as one of the three 'Parts of Lincolnshire', along with Holland in the south-east and Kesteven in the south west.
Lindum Colonia was the Latin name for the settlement which is now the City of Lincoln in Lincolnshire. It was founded as a Roman Legionary Fortress during the reign of the Emperor Nero or possibly later. Evidence from Roman tombstones suggests that Lincoln was first garrisoned by the Ninth Legion Hispana, which probably moved from Lincoln to found the fortress at York around c. 71 AD. Lindum was then garrisoned by the Second Legion Adiutrix, which then went on to Chester in 77–78 AD.
Eorpwald; also Erpenwald or Earpwald,, succeeded his father Rædwald as ruler of the independent Kingdom of the East Angles. Eorpwald was a member of the East Anglian dynasty known as the Wuffingas, named after the semi-historical king Wuffa.
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.
Hereswith or Hereswitha, also spelt Hereswithe, Hereswyde or Haeresvid, was a 7th-century Northumbrian saint. She married into the East Anglian royal dynasty and afterwards retired to Gaul to lead a religious life. Hereswith's sister was Saint Hilda, founder of the monastery at Whitby. Details of her life and identity come from Bede's Historia Ecclesiastica, the Anglian collection and the Lives of Edwin of Northumbria and Hilda of Whitby.
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 England 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 Mercia, Northumbria, Wessex and East Anglia.
The Lindisfaras were an Anglian tribe who, in the 6th century, established the kingdom of Lindsey between the valleys of the rivers Humber and Witham, in the north of what is now Lincolnshire. They retained their administrative independence throughout the 7th century but, following the Battle of the Trent between the kingdoms of Mercia and Northumbria, remained under Mercian control until the Viking invasion of the ninth century. According to D. P. Kirby, the Heathfeld Land of Yorkshire mentioned as part of the Lindisfaras' 7000 hides listed in the Tribal Hidage, was Hatfield Chase.
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.
A number of royal genealogies of the Anglo-Saxon kingdoms, collectively referred to as the Anglo-Saxon royal genealogies, have been preserved in a manuscript tradition based in the 8th to 10th centuries.
