Anglo-Saxon Chronicle in the context of "Battle of Fulford"

The Danelaw (/ˈdeɪnˌlɔː/, Danish: Danelagen; Norwegian: Danelagen; Old English: Dena lagu) was the part of England between the late ninth century and the Norman Conquest under Anglo-Saxon rule in which Danish laws applied. The Danelaw originated in the conquest and occupation of large parts of eastern and northern England by Danish Vikings in the late ninth century. The term applies to the areas in which English kings allowed the Danes to keep their own laws following the early tenth-century Anglo-Saxon conquest of Danish ruled eastern and northern England in return for the Danish settlers' loyalty to the English crown. "Danelaw" is first recorded in the early 11th century as Dena lage.

The Danelaw originated from the invasion of the Great Heathen Army into England in 865, but the term was not used to describe a geographic area until the 11th century. With the increase in population and productivity in Scandinavia, Viking warriors, having sought treasure and glory in the nearby British Isles, "proceeded to plough and support themselves", in the words of the Anglo-Saxon Chronicle for 876.

Layamon's Brut (c. 1190 – c. 1215), also known as The Chronicle of Britain, is a Middle English alliterative verse poem compiled and recast by the English priest Layamon. Layamon's Brut is 16,096 lines long and narrates a fictionalized version of the history of Britain up to the Early Middle Ages. It was the first work of history written in English since the Anglo-Saxon Chronicle. Named for Britain's mythical founder, Brutus of Troy, the poem is largely based on the Anglo-Norman French Roman de Brut by Wace, which is in turn a version of Geoffrey of Monmouth's Latin Historia Regum Britanniae. Layamon's poem, however, is longer than both and includes an enlarged section on the life and exploits of King Arthur. It is written in the alliterative verse style commonly used in Middle English poetry by rhyming chroniclers, the two halves of the alliterative lines being often linked by rhyme as well as by alliteration.

Like the earlier Latin works, it is now regarded as valueless as history. It gives the history of the Britons, largely ignoring the Anglo-Saxons. Its narrative ends with the Welsh king Cadwallon ap Cadfan, who died in 634.

Domesday Book (/ˈduːmzdeɪ/ DOOMZ-day; the Middle English spelling of "Doomsday Book") is a manuscript record of the Great Survey of much of England and parts of Wales completed in 1086 at the behest of William the Conqueror. The manuscript was originally known by the Latin name Liber de Wintonia, meaning "Book of Winchester", where it was originally kept in the royal treasury. The Anglo-Saxon Chronicle states that in 1085 the king sent his agents to survey every shire in England, to list his holdings and dues owed to him.

Written in Medieval Latin, it was highly abbreviated and included some vernacular native terms without Latin equivalents. The survey's main purpose was to record the annual value of every piece of landed property to its lord, and the resources in land, labour force, and livestock from which the value derived.

The Roman Baths are well-preserved thermae in the city of Bath, Somerset, England. A temple was constructed on the site between 60 and 70 AD in the first few decades of Roman Britain. Its presence led to the development of the small Roman urban settlement known as Aquae Sulis around the site. The Roman baths—designed for public bathing—were used until the end of Roman rule in Britain in the 5th century AD. According to the Anglo-Saxon Chronicle, the original Roman baths were in ruins a century later. The area around the natural springs was redeveloped several times during the Early and Late Middle Ages.

The Roman Baths are preserved in four main features: the Sacred Spring, the Roman Temple, the Roman Bath House, and a museum which holds artefacts from Aquae Sulis. However, all buildings at street level date from the 19th century. It is a major tourist attraction in the UK, and together with the Grand Pump Room, receives more than 1.3 million visitors annually. Visitors can tour the baths and museum but cannot enter the water.

The Kingdom of the West Saxons, also known as the Kingdom of Wessex, was an Anglo-Saxon kingdom in the south of Great Britain, from around 519 until Alfred the Great declared himself as King of the Anglo-Saxons in 886.

The Anglo-Saxons believed that Wessex was founded by Cerdic and Cynric of the Gewisse, though this is considered by some to be a legend. The two main sources for the history of Wessex are the West Saxon Genealogical Regnal List and the Anglo-Saxon Chronicle (the latter of which drew on and adapted an early version of the List), which sometimes conflict. Wessex became a Christian kingdom after Cenwalh (r. 642–645, 648–672) was baptised and was expanded under his rule. Cædwalla later conquered Sussex, Kent and the Isle of Wight. His successor, Ine (r. 689–726), issued one of the oldest surviving English law codes and established a second West Saxon bishopric. The throne subsequently passed to a series of kings with unknown genealogies.

A menologium (/mɛnəˈloʊdʒiəm/, pl. menologia), also known by other names, is any collection of information arranged according to the days of a month, usually a set of such collections for all the months of the year. In particular, it is used for ancient Roman farmers' almanacs (menologia rustica); for the untitled Old English poem on the Julian calendar that appears in a manuscript of the Anglo-Saxon Chronicle; for the liturgical books (also known as the menaia) used by the Eastern Orthodox Church and Eastern Catholic Churches following the Byzantine Rite that list the propers for fixed dates, typically in twelve volumes covering a month each and largely concerned with saints; for hagiographies (also known as synaxaria) and liturgical calendars written as part of this tradition; and for equivalents of these works among Roman Catholic religious orders for organized but private commemoration of their notable members.

Ecgberht (died 839), 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.

Little is known of the first 20 years of Ecgberht's reign, but it is thought that he was able to maintain the independence of Wessex against the kingdom of Mercia, which at that time dominated the other southern English kingdoms. In 825, Ecgberht defeated Beornwulf of Mercia, ended Mercian Supremacy at the Battle of Ellandun, and proceeded to take control of the Mercian dependencies in southeastern England. In 829, he defeated Wiglaf of Mercia and drove him out of his kingdom, temporarily ruling Mercia directly. Later that year Ecgberht received the submission of the Northumbrian king at Dore. The Anglo-Saxon Chronicle subsequently described Ecgberht as a bretwalda or 'wide-ruler' of Anglo-Saxon lands.

Mercia (/ˈmɜːrsiə, -ʃə/) was one of the principal kingdoms founded at the end of Sub-Roman Britain; the area 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.

The royal court moved around the kingdom without a fixed capital city. Early in its existence Repton seems to have been the location of an important royal estate. According to the Anglo-Saxon Chronicle, it was from Repton in 873–874 that the Great Heathen Army deposed the King of Mercia. Slightly earlier, King Offa seems to have favoured Tamworth. It was there where he was crowned, and where he resided during multiple Christmases.
