Northumbria was an early medieval English kingdom, existing between 654 and 1066 AD, at its height spanning modern-day Northern England and Southern Scotland.
The name derives from the Old English Norþhymbre meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. What was to become Northumbria started as two kingdoms, Deira in the south and Bernicia in the north. Conflict in the first half of the seventh century ended with the murder of the last king of Deira in 651, and Northumbria was thereafter unified under Bernician kings.
At its height, the kingdom extended from the Humber, Peak District and the River Mersey on the south to the Firth of Forth on the north. Northumbria ceased to be an independent kingdom in the mid-tenth century when Deira was conquered by the Danes and formed into the Kingdom of York. The rump Earldom of Bamburgh maintained control of Bernicia for a period of time; however, the area north of the Tweed was eventually absorbed into the medieval Kingdom of Scotland while the portion south of the Tweed was absorbed into the Kingdom of England as the county of Northumberland and County Palatine of Durham.

Communities and divisions
Possible Celtic British origins
The Anglo-Saxon kingdom of Northumbria was originally two kingdoms divided approximately around the River Tees: Bernicia was to the north of the river and Deira to the south. It is possible that both regions originated as native Celtic British kingdoms, which the Germanic settlers later conquered, although there is very little information about the infrastructure and culture of the British kingdoms themselves. Much of the evidence for them comes from regional names that are British rather than Anglo-Saxon in origin. The names Deira and Bernicia are likely British in origin, for example, indicating that some British place names retained currency after the Anglo-Saxon migrations to Northumbria. There is also some archaeological evidence to support British origins for the polities of Bernicia and Deira. In what would have been southern Bernicia, in the Cheviot Hills, a hill fort at Yeavering Bell contains evidence that it was an important centre for first the British and later the Anglo-Saxons. The fort is originally pre-Roman, dating back to the Iron Age at around the first century. In addition to signs of Roman occupation, the site contains evidence of timber buildings that pre-date Germanic settlement in the area that are probably signs of British settlement. Moreover, Brian Hope-Taylor has traced the origins of the name Yeavering, which looks deceptively English, back to the British gafr from Bede's mention of a township called Gefrin in the same area. Yeavering continued to be an important political centre after the Anglo-Saxons began settling in the north, as King Edwin had a royal palace at Yeavering.
Overall, English place-names dominate the Northumbrian landscape, suggesting the prevalence of an Anglo-Saxon elite culture by the time that Bede —Anglo-Saxon England's most prominent historian —was writing in the eighth century. According to Bede, the Angles were the predominant Germanic immigrants, who settled north of the Humber and gained political prominence during this period. While the British natives may have partially assimilated into the Northumbrian political structure, relatively contemporary textual sources such as Bede's Ecclesiastical History of the English People depict relations between Northumbrians and the British as fraught.
Unification of Bernicia and Deira
The Anglo-Saxon states of Bernicia and Deira were often in conflict before their eventual semi-permanent unification in 651. Political power in Deira was concentrated in the East Riding of Yorkshire, which included York, the North York Moors, and the Vale of York. The political heartlands of Bernicia were the areas around Bamburgh and Lindisfarne, Monkwearmouth and Jarrow, and in Cumbria, west of the Pennines in the area around Carlisle. The name that these two states eventually united under, Northumbria, might have been coined by Bede and made popular through his Ecclesiastical History of the English People.
Information on the early royal genealogies for Bernicia and Deira comes from Bede's Ecclesiastical History of the English People and Nennius' Historia Brittonum. According to Nennius, the Bernician royal line begins with Ida, son of Eoppa. Ida reigned for twelve years (beginning in 547) and was able to annex Bamburgh to Bernicia. In Nennius' genealogy of Deira, a king named Soemil was the first to separate Bernicia and Deira, which could mean that he wrested the kingdom of Deira from the native British. The date of this supposed separation is unknown. The first Deiran king to make an appearance in Bede's Historia Ecclesiastica Gentis Anglorum is Ælla, the father of the first Christian Northumbrian king Edwin.
A king of Bernicia, Ida's grandson Æthelfrith, was the first ruler to unite the two polities under his rule. He exiled the Deiran Edwin to the court of King Rædwald of East Anglia to claim both kingdoms, but Edwin returned in approximately 616 to conquer Northumbria with Rædwald's aid. Edwin, who ruled from approximately 616 to 633, was one of the last kings of the Deiran line to reign over all of Northumbria. Oswald's brother Oswiu eventually succeeded him to the Northumbrian throne despite initial attempts on Deira's part to pull away again. The last independent king of Deira was Oswine. He was murdered by Oswiu in 651, and Northumbria was thereafter united under Bernician rule.
While violent conflicts between Bernicia and Deira played a significant part in determining which line ultimately gained supremacy in Northumbria, marriage alliances also helped bind these two territories together. Æthelfrith married Edwin's sister Acha, although this marriage did little to prevent future squabbles between the brothers-in-law and their descendants. The second intermarriage was more successful, with Oswiu marrying Edwin's daughter and his own cousin Eanflæd to produce Ecgfrith, the beginning of the Northumbrian line. However, Oswiu had another relationship with an Irish woman named Fina which produced the problematic Aldfrith. In his Life and Miracles of St. Cuthbert, Bede declares that Aldfrith, known as Fland among the Irish, was illegitimate and therefore unfit to rule.
Northumbria and Norse settlement
The Viking invasions of the ninth century and the establishment of the Danelaw once again divided Northumbria. Although primarily recorded in the southern provinces of England, the Anglo-Saxon Chronicles (particularly the D and E recensions) provide some information on Northumbria's conflicts with Vikings in the late eighth and early ninth centuries. According to these chronicles, Viking raids began to affect Northumbria when a band attacked Lindisfarne in 793. After this initial catastrophic blow, Viking raids in Northumbria were either sporadic for much of the early ninth century or evidence of them was lost. However, in 865 the so-called Great Heathen Army landed in East Anglia and began a sustained campaign of conquest. The Great Army fought in Northumbria in 866–867, striking York twice in less than one year. After the initial attack the Norse left to go north, leaving Kings Ælle and Osberht to recapture the city. The E recension of the Anglo-Saxon Chronicle suggests that Northumbria was particularly vulnerable at this time because the Northumbrians were once again fighting amongst themselves, deposing Osberht in favour of Ælle. In the second raid, the Vikings killed Kings Ælle and Osberht whilst recapturing the city.
After King Alfred re-established his control of southern England, the Norse invaders settled into what came to be known as the Danelaw in the Midlands, East Anglia, and the southern part of Northumbria. In Northumbria, the Norse established the Kingdom of York whose boundaries were roughly the River Tees and the Humber, giving it approximately the same dimensions as Deira. Although this kingdom fell to Hiberno-Norse colonisers in the 920s and was in constant conflict with the West-Saxon expansionists from the south, it survived until 954 when the last Scandinavian king Eric, who is usually identified as Eric Bloodaxe, was driven out and eventually killed.
In contrast, the Great Army was not as successful in conquering territory north of the River Tees. Some raids extended into that area, but no sources mention lasting Norse occupation and there are very few Scandinavian place names to indicate significant Norse settlement in northern regions of Northumbria. The political landscape of the area north of the Tees during the Viking conquest of Northumbria consisted of the Community of St. Cuthbert and the remnants of the English Northumbrian elites. While the religious Community of St. Cuthbert "wandered" for a hundred years after Halfdan Ragnarsson attacked their original home of Lindisfarne in 875, The History of St. Cuthbert indicates that they settled temporarily at Chester-le-Street between the years 875–883 on land granted to them by the Viking King of York, Guthred. According to the twelfth-century account Historia Regum, Guthred granted them this land in exchange for establishing him as king. The land extended from the Tees to the Tyne and anyone who fled there from either the north or the south would receive sanctuary for thirty-seven days, indicating that the Community of St. Cuthbert had some juridical autonomy. Based on their positioning and this right of sanctuary, this community probably acted as a buffer between the Norse in southern Northumbria and the Anglo-Saxons who continued to hold the north.
North of the Tyne, Northumbrians maintained partial political control in Bamburgh. The rule of kings continued in that area with Ecgberht I acting as regent around 867 and the kings Ricsige and Ecgberht II immediately following him. According to twelfth-century historian Symeon of Durham, Ecgberht I was a client-king for the Norse. The Northumbrians revolted against him in 872, deposing him in favour of Ricsige. Although the A and E recensions of the Anglo-Saxon Chronicle report that Halfdan was able to take control of Deira and take a raiding party north of the River Tyne to impose his rule on Bernicia in 874, after Halfdan's death (c. 877) the Norse had difficulty holding on to territory in northern Bernicia. Ricsige and his successor Ecgberht were able to maintain an English presence in Northumbria. After the reign of Ecgberht II, Eadwulf "King of the North Saxons" (r. 890–912) succeeded him for control of Bamburgh, but after Eadwulf's death, rulership of this area switched over to earls who were possible kinsmen or direct descendants of the royal Northumbrian house.
Kings
Æthelfrith (r. 593–616)
Æthelfrith was the first Anglo-Saxon leader to hold the thrones of both Deira and Bernicia, and so he ruled over all the people north of the Humber. His rule was notable for his numerous victories over the Britons and the Gaels.
Edwin (r. 616–633)
Edwin, like Æthelfrith, was king of both Deira and Bernicia and ruled them from 616 to 633. Under his reign, the Isle of Man and the lands of Gwynedd in Northern Wales were incorporated into Northumbria. Edwin married Æthelburh, a Christian Princess from Kent in 625. He converted to Christianity two years later, after a period of heavy consideration and after consulting numerous advisors. Edwin fell in battle in 633 against Cadwallon of Gwynedd and the pagan Penda of Mercia. He was venerated as a saint and martyr after his death.
Oswald (r. 634–642)
Oswald was a king of Bernicia, who regained the kingdom of Deira after defeating Cadwallon in 634. Oswald then ruled Northumbria until he died in 642. A devout Christian, Oswald worked tirelessly to spread the faith in his traditionally pagan lands. It was during his reign that the monastery at Lindisfarne was created. Oswald fell in the Battle of Maserfield against Penda of Mercia in 642, but his influence endured because, like Edwin, Oswald was venerated as a saint after his death.
Oswiu (r. 642–670)
Oswiu was the brother of Oswald and succeeded him after the latter's defeat in Maserfield. Oswiu succeeded where Edwin and Oswald failed as, in 655, he slew Penda during the Battle of the Winwaed, making him the first Northumbrian King also to control the kingdom of Mercia. During his reign, he presided over the Synod of Whitby, an attempt to reconcile religious differences between Roman and Celtic Christianity, in which he eventually backed Rome. Oswiu died from illness in 670 and divided Deira and Bernicia between two of his sons. His son Aldfrith of Northumbria took over the throne upon his death.
