Timeline of conflict in Anglo-Saxon Britain
The Timeline of conflict in Anglo-Saxon Britain is concerned with the period of history from just before the departure of the Roman Army, in the 4th century, to just after the Norman Conquest in the 11th century.
The information is mainly derived from annals and the Venerable Bede. The dates, particularly from the fourth to the late sixth centuries, have very few contemporary sources and are largely later constructions by medieval chroniclers. The historian Diana Greenway described one such 12th century chronicler, Henry of Huntingdon, as a 'weaver' compiler of history, and the archaeologist Martin Welch described the Anglo-Saxon Chronicle as "a product of the West Saxon court... concerned with glorifying the royal ancestry of Alfred the Great. Manipulation of royal genealogies, in this and other sources, to enhance the claims of present rulers was common. Literary formulas associated with original myths are a common feature of earlier entries." Although the timeline uses the annals for this period of history, information provided by these sources can be problematic, particularly with the earlier dates.
Constructing a chronology of the early Anglo-Saxon period, and how the Anglo-Saxons took over land in Britain from Celtic-speaking or Latin-speaking Romano-Britons, is highly complex. The limitations of source material place restrictions on just how accurate any chronology can be. As an example, the following table shows how much variation there is between historians on just one date, the Battle of Badon:
|Suggested dates for the Battle of Badon|
|Higham||c.430 - c.440|
|Morris||494 - 497|
|I.Wood||c.485 - c.520|
Much of the dating of the period comes from Bede (672/673–735), who in his Ecclesiastical History of the English People, tried to compute dates for events in early Anglo-Saxon history. Although primarily writing about church history, Bede is seen as Britain's first true historian, in that he cited his references and listed events according to dates rather than regnal lists. So we know that he relied heavily on De Excidio et Conquestu Britanniae by Gildas, a sixth century cleric, for his early dates and historians have found Gildas unreliable where dates were concerned. Bede's work was widely read among the literate in the Anglo-Saxon kingdoms, and his dates were used by the monks who compiled the various Anglo-Saxon Chronicles from the late ninth century onwards.
The most controversial dates in the period — those from the fourth to the late sixth centuries — have very few contemporary sources, and are mainly derived from later attempts to construct Anglo-Saxon history.
The following is an outline of some events recorded in Bede's Ecclesiastical History, the Anglo-Saxon Chronicle, the Welsh Annals (Annales Cambriae), and Brut y Tywysogion. Many of the dates from the fourth, fifth, and sixth century are points of contention.
- 410 CE: Emperor Honorius refuses a call for help from Britain, tells the cities to look to their own defence. 
- c.430 to 520: The range of dates for the Battle of Badon. See effects of the battle for the strategic situation resulting afterwards.
- About 446: The "Groans of the Britons" - A last appeal (possibly to the Consul Aetius) for the Roman army to come back to Britain.
- 449: Vortigern invites Anglo-Saxons to come and help them against the Picts, who were raiding the east coast, and allows them to settle on "The eastern side of the island." (The name Vortigern may mean "Great King" rather than being a lifelong personal name.)
- 455: [ASC 1] (Battle of Aylesford: Here Hengest and Horsa fought against Vortigern the king, in the place that is called Aylesford, and his brother Horsa was slain; and after that Hengest took the throne with Æsc, his son.)
- 457: [ASC 2] (Here Hengest & Æsc fought against Britons in the place which is called Crecganford and there slew 4000 men, and the Britons abandoned Kent and with great fear fled to London.)
- 465: [ASC 3] (466 [corrected from 465]: Battle of Wippedesfleot: Here Hengest and Æsc fought together against the Welsh (meaning 'foreigner': the manner in which the invaders referred to the Britons) near Wippedesfleot and there slew 12 Welsh leaders, and one of their thanes was slain, whose name was Wipped. [This battle is said to have resulted in much bloodshed and slaughter on both sides, to the extent that hostilities abated for a while thereafter. It is not known where Wippedesfleot (= "Wipped's tidal estuary") was.])
- 473: [ASC 4] (Here Hengest & Æsc fought against Welsh and took countless war-loot, and the Welsh fled from the English like fire.)
- 477:(?) [ASC 5] (Here Ælle came to Britain and [with him] his 3 sons Cymen & Wlencing & Cissa, with 3 ships to the place which is named Cymenesora [probably now The Owers, rocks off Selsey in West Sussex ], and there slew many Welsh & drove some in flight into the wood which is called Andredesleag [= The Weald ].)
- 485: [ASC 6] (Here Ælle fought against Welsh near the margin of Mearcrædesburna [= Mearcræd's stream].)
- 491: [ASC 7] (Here Ælle and Cissa besieged Andredescester [now Pevensey ] and slew all who dwelt therein; no Briton was left [alive] afterwards.)
- Around 500 AD: Average of suggested dates for the Battle of Badon.
- Around 500 AD: Angles colonised the North Sea and Humber coastal areas, particularly around Holderness.
- 501: [ASC 8] (Here Port and his 2 sons Bieda and Mægla came to Britain with 2 ships to the place which is called Portsmouth and slew a young British man, a very noble man. [But this may be an old fiction, as a folk-etymology to explain the placename Ports-mouth.] )
- 508: [ASC 9] (Here Cerdic and Cynric slew a British king, whose name was Natanleod, and 5000 men with him. Afterwards that land was named Natanleag as far as Cerdicesford [= North Charford and South Charford ].)
- 535 & 536: The extreme weather events of 535-536 likely caused a great famine and thus population loss.
- On or before 547: Bernicia established by Anglo-Saxons taking over part of a Celtic area called Bryneich.
- Around 549: A great plague caused much population loss.
- About 560: Anglo-Saxons conquered all of east Yorkshire and the British kingdom of Ebrauc, and there established Deira.
- 571: [ASC 10] (Battle of Bedcanford: Here Cuthwulf fought against Britons at Bedcanford and took 4 settlements: Limbury, Aylesbury, Benson & Eynsham. And in the same year he died.)
- 573: Battle of Arfderydd at Arthuret in Cumbria: Celt fought Celt and weakened their numbers.
- 577: [ASC 11] (Battle of Dyrham: Here Cuthwine and Ceawlin fought against Britons and they slew 3 kings: Coinmail & Condidan & Farinmail, in the place which is called Dyrham, and took 3 towns: Gloucester & Cirencester & Bath. ): These entries seem to show that the Britons' defences in the English Midlands collapsed, and the peace that followed the Battle of Mons Badonicus ended, and the Anglo-Saxons obliterated the British Watling Street salient and united their areas and overran the London - Verulamium area and much of the plain of the Midlands. Loss of Bath would separate the Welsh from the Britons of the southwest. After this, the border between Saxons and the southwest Celts was probably at the Wansdyke along the ridge of the Mendip Hills.
- 581: Ælla of Deira took land from the Britons, thus establishing or enlarging Deira.
- Around 584: The Kingdom of the Iclingas became Mercia.
- 584: [ASC 12] (Battle of Fethanleag: Here Ceawlin and Cutha fought against Britons in the place that is named Fethanleag and Cutha was slain, and Ceawlin took many settlements and countless war-loot, and in anger he returned to his own land.)
- 590: Elmet joined an alliance of Celtic kingdoms against the expanding Angles of Bernicia. See Elmet and History of Yorkshire#Sub-Roman.
- Afterwards: The Celtic leader Urien of Rheged was murdered. A feud broke out between two of this alliance's key members.
- Around 600: Battle of Catraeth (Catterick): also see Y Gododdin: An army from the Celtic kingdom of Gododdin fell in battle against the Angles of Deira and Bernicia at Catterick in Yorkshire.
- Around 604: Deira and Bernicia united as Northumbria.
- Afterwards: Elmet built earthworks north and west of Barwick-in-Elmet, where Elmet's king's seat was.

- 616: Autumn - Northumbria invaded and conquered Elmet.
- 616: Likeliest date for the Battle of Chester, between a Northumbrian army and a Welsh army: heavy Welsh casualties, and their defeat severed the land connection between Wales and the Celts of northwest Britain.
- 633, October 12: Battle of Hatfield (AC: 630, Meigen) near Doncaster in Yorkshire: Gwynedd and Mercia attacked and defeated Northumbria; Elmet and Ebrauc temporarily returned to Celtic rule.
- 633 or 634: Battle of Heavenfield (AC: 631, Cantscaul) about 6 miles NW of Hexham: Northumbria expels the Gwynedd army.
- 642: [ASC 14] (Here Oswald king of Northumbria was slain) This may be the same battle as:-
- 644: The Battle of Maserfield (alias Battle of Maes Cogwy), in which Oswald king of the Northmen and Eawa king of the Celtic Mercians fell. AC B
- 652: Cenwalh of Wessex won a battle at Bradford-on-Avon.

He was there 3 years in exile. Penda had driven him out, and taken his kingdom, because he abandoned his [= Penda's] sister.)
- 682: [ASC 16] This year also, Centwine chased the Britons into the sea.
- 710: [ASC 17] (... and in the same year ealdorman Beorhtfrith fought against Picts between [the rivers] Avon and Carron [which flow into the River Forth from the south about 20 miles west of Edinburgh ], and Ine and his relative Nunna fought against Geraint king of Welsh ... [This second battle may have been the Battle of Llongborth.] ) ...
- 722: According to the Annales Cambriae, 722 saw "the battle of Hehil among the Cornish, the battle of Garth Maelog, [and] the battle of Pencon among the south Britons, and the Britons were the victors in those three battles."

- 835: [ASC 21] (838 [corrected from 835]: Here a great ship-army [of Vikings] came to Cornwall and they [= the Cornish] joined them, and were fighting against Ecgbryht king of the West Saxons. Then he heard and with an army fought against them at Hengestdun and there put to flight both the Cornish and the Danes.)

He was writing in the late 5th and early 6th century. His work was copying earlier sources and it seems that he may have compressed a lot of the dates. Also the Rescript of Honorius was in a section discussing northern Italy and Liguria. It has been suggested that the name copied down was in error and that the copyist mistranscribed Brettannia (Britain) for Brettia or Brittia, which is a place in southern Italy
