Æthelstan in the context of Malmesbury

The Kingdom of England was a sovereign state on the island of Great Britain from the 10th century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.

Beginning in the year 886 Alfred the Great reoccupied London from the Danish Vikings and after this event he declared himself King of the Anglo-Saxons, until his death in 899. During the early tenth century, the various Anglo-Saxon kingdoms were united by Alfred's descendants Edward the Elder (reigned 899–924) and Æthelstan (reigned 924–939) to form the Kingdom of the English. In 927, Æthelstan conquered the last remaining Viking kingdom, York, making him the first Anglo-Saxon ruler of the whole of England. In 1016, the kingdom became part of the North Sea Empire of Cnut the Great, a personal union between England, Denmark and Norway. The Norman Conquest in 1066 led to the transfer of the English capital city and chief royal residence from the Anglo-Saxon one at Winchester to Westminster, and the City of London quickly established itself as England's largest and principal commercial centre.

The House of Wessex, also known as the House of Cerdic, the House of the West Saxons, the House of the Gewisse, the Cerdicings and the West Saxon dynasty, refers to the family, traditionally founded by Cerdic of the Gewisse, that ruled Wessex in Southern England from the early 6th century. The house became dominant in southern England after the accession of King Ecgberht in 802. Alfred the Great saved England from Viking conquest in the late ninth century and his grandson Æthelstan became first king of England in 927. The disastrous reign of Æthelred the Unready ended in Danish conquest in 1014. Æthelred and his son Edmund Ironside attempted to resist the Vikings in 1016, but after their deaths the Danish Cnut the Great and his sons ruled until 1042. The House of Wessex then briefly regained power under Æthelred's son Edward the Confessor, but lost it after the Confessor's reign, with the Norman Conquest in 1066. All monarchs of England (and subsequently Great Britain) since William II have been descended from the House of Wessex through William the Conqueror's wife Matilda of Flanders, who was a descendant of Alfred the Great through his daughter Ælfthryth. All English and later British monarchs since Henry II are descended from the English kings of the House of Wessex through Henry I's wife, Matilda of Scotland, daughter of Margaret of Wessex, a great-granddaughter of Edmund Ironside.

Edmund I or Eadmund I (920/921 – 26 May 946) was King of the English from 27 October 939 until his death in 946. He was the elder son of King Edward the Elder and his third wife, Queen Eadgifu, and a grandson of King Alfred the Great. After Edward died in 924, he was succeeded by his eldest son, Edmund's half-brother Æthelstan. Edmund was crowned after Æthelstan died childless in 939. He had two sons, Eadwig and Edgar, by his first wife Ælfgifu, and none by his second wife Æthelflæd. His sons were young children when he was killed in a brawl with an outlaw at Pucklechurch in Gloucestershire, and he was succeeded by his younger brother Eadred, who died in 955 and was followed by Edmund's sons in succession.

Æthelstan had succeeded as the king of England south of the Humber and he became the first king of all England when he conquered Viking-ruled York in 927, but after his death Anlaf Guthfrithson was accepted as King of York and extended Viking rule to the Five Boroughs of north-east Mercia. Edmund was initially forced to accept the reverse, the first major setback for the West Saxon dynasty since Alfred's reign, but he was able to recover his position following Anlaf's death in 941. In 942, Edmund took back control of the Five Boroughs and in 944 he regained control over the whole of England when he expelled the Viking kings of York. Eadred had to deal with further revolts when he became king, and York was not finally conquered until 954. Æthelstan had achieved a dominant position over other British kings and Edmund maintained this, perhaps apart from Scotland. The north Welsh king Idwal Foel may have allied with the Vikings as he was killed by the English in 942. The British kingdom of Strathclyde may also have sided with the Vikings as Edmund ravaged it in 945 and then ceded it to Malcolm I of Scotland. Edmund also continued his brother's friendly relations with Continental rulers, several of whom were married to his half-sisters.

The English Benedictine Reform or Monastic Reform of the English church in the late tenth century was a religious and intellectual movement in the later Anglo-Saxon period. In the mid-tenth century almost all monasteries were staffed by secular clergy, who were often married. The reformers sought to replace them with celibate contemplative monks following the Rule of Saint Benedict. The movement was inspired by Continental monastic reforms, and the leading figures were Dunstan, Archbishop of Canterbury, Æthelwold, Bishop of Winchester, and Oswald, Archbishop of York.

In seventh- and eighth-century England, most monasteries were Benedictine, but in the ninth century learning and monasticism declined severely. Alfred the Great (871–899) deplored the decline and started to reverse it. The court of Æthelstan (924–939), the first king of the whole of England, was cosmopolitan, and future reformers such as Dunstan and Æthelwold learned from Continental exponents of Benedictine monasticism. The English movement became dominant under King Edgar (959–975), who supported the expulsion of secular clergy from monasteries and cathedral chapters, and their replacement by monks. The reformers had close relations with the Crown, furthering its interests and depending on its support. The movement was confined to southern England and the Midlands, as the Crown was not strong enough in northern England to confiscate property from local elites there to establish Benedictine foundations. The movement declined after the deaths of its leading exponents at the end of the tenth century.

Thomas Hardy's Wessex is the fictional literary landscape created by the English author Thomas Hardy as the setting for his major novels, located in the south and southwest of England. Hardy named the area "Wessex" after the medieval Anglo-Saxon kingdom that existed in this part of that country prior to the unification of England by Æthelstan. Although the places that appear in his novels actually exist, in many cases he gave the place a fictional name. For example, Hardy's home town of Dorchester is called Casterbridge in his books, notably in The Mayor of Casterbridge. In an 1895 preface to the 1874 novel Far from the Madding Crowd he described Wessex as "a merely realistic dream country".

The actual definition of "Hardy's Wessex" varied widely throughout Hardy's career, and was not definitively settled until after he retired from writing novels. When he created the concept of a fictional Wessex, it consisted merely of the small area of Dorset in which Hardy grew up; by the time he wrote Jude the Obscure, the boundaries had extended to include all of Dorset, Wiltshire, Somerset, Devon, Hampshire, much of Berkshire, and some of Oxfordshire, with its most north-easterly point being Oxford (renamed "Christminster" in the novel). Cornwall was also referred to but named "Off Wessex". Similarly, the nature and significance of ideas of "Wessex" were developed over a long series of novels through a lengthy period of time. The idea of Wessex plays an important artistic role in Hardy's works (particularly his later novels), assisting the presentation of themes of progress, primitivism, sexuality, religion, nature and naturalism. However, this is complicated by the economic role Wessex played in Hardy's career. Considering himself primarily to be a poet, Hardy wrote novels mostly to earn money. Books that could be marketed under the Hardy brand of "Wessex novels" were particularly lucrative, which gave rise to a tendency to sentimentalised, picturesque, populist descriptions of Wessex.

Ecgwynn (also spelled Ecgwynna; Old English: Eċġwynn, meaning “sword joy”; fl. 890s) was the first known consort of Edward the Elder, who reigned as King of the English from 899 to 924. She was the mother of Æthelstan (r. 924–939), the first monarch to rule a unified England, and is also believed to have had a daughter who married Sitric Cáech, Norse king of Dublin,Ireland and Northumbria.

Virtually nothing is known about Ecgwynn’s origins or personal life and her name is absent from all contemporary records and does not appear in any surviving sources until after the Norman Conquest. The earliest known reference comes from William of Malmesbury, who Latinized her name as Egwinna and who is in fact the principal source for her existence.

The Battle of Brunanburh was fought in 937 between Æthelstan, King of England, and an alliance of Olaf Guthfrithson, King of Dublin; Constantine II, King of Scotland; and Owain, King of Strathclyde. The battle is sometimes cited as the point of origin for English national identity: historians such as Michael Livingston argue that "the men who fought and died on that field forged a political map of the future that remains, arguably making the Battle of Brunanburh one of the most significant battles in the long history not just of England, but of the whole of the British Isles."

Following an unchallenged invasion of Scotland by Æthelstan in 934, possibly launched because Constantine had violated a peace treaty, it became apparent that Æthelstan could be defeated only by an alliance of his enemies. Olaf led Constantine and Owen in the alliance. In August 937 Olaf and his army sailed from Dublin to join forces with Constantine and Owen, but they were routed in the battle against Æthelstan. The poem "Battle of Brunanburh" in the Anglo-Saxon Chronicle recounts that there were "never yet as many people killed before this with sword's edge ... since the east Angles and Saxons came up over the broad sea".

The royal consorts of Wessex were the wives of the reigning monarchs of the Kingdom of Wessex. History has not always recorded whether each king of Wessex was married or not. In Wessex it was not customary for kings' wives to be queens but Judith was crowned queen following her marriage to Æthelwulf.

Wessex was an Anglo-Saxon kingdom in the south of Great Britain, from 519 AD until England was unified by Æthelstan (who never married) in 927 AD.

Dish-bearers (often called seneschals by historians) and butlers (or cup-bearers) were thegns who acted as personal attendants of kings in Anglo-Saxon England. Royal feasts played an important role in consolidating community and hierarchy among the elite, and dish-bearers and butlers served the food and drinks at these meals. Thegns were members of the aristocracy, leading landowners who occupied the third lay (non-religious) rank in English society after the king and ealdormen. Dish-bearers and butlers probably also carried out diverse military and administrative duties as required by the king. Some went on to have illustrious careers as ealdormen, but most never rose higher than thegn.

Eadred (also Edred, c. 923 – 23 November 955) was King of the English from 26 May 946 until his death in 955. He was the younger son of Edward the Elder and his third wife Eadgifu, and a grandson of Alfred the Great. His elder brother, Edmund, was killed trying to protect his seneschal from an attack by a violent thief. Edmund's two sons, Eadwig and Edgar, were then young children, so Eadred became king. He suffered from ill health in the last years of his life and he died at the age of a little over thirty, having never married. He was succeeded successively by his nephews, Eadwig and Edgar.

Eadred's elder half-brother Æthelstan inherited the kingship of England south of the Humber in 924, and conquered the south Northumbrian Viking kingdom of York in 927. Edmund and Eadred both inherited kingship of the whole kingdom, lost it shortly afterwards when York accepted Viking kings, and recovered it by the end of their reigns. In 954, the York magnates expelled their last king, Erik Bloodaxe, and Eadred appointed Osullf, the Anglo-Saxon ruler of the north Northumbrian territory of Bamburgh, as the first ealdorman of the whole of Northumbria.

Olaf Guthfrithson or Anlaf Guthfrithson (Old Norse: Óláfr Guðrøðsson [ˈoːˌlɑːvz̠ ˈɡuðˌrøðsˌson]; Old English: Ánláf; Old Irish: Amlaíb mac Gofraid; died 941) was a Hiberno-Scandinavian (Irish-Viking) leader who ruled Dublin and Viking Northumbria in the 10th century. He was the son of Gofraid ua Ímair and great-grandson of Ímar, making him one of the Uí Ímair. Olaf succeeded his father as King of Dublin in 934 and succeeded in establishing dominance over the Vikings of Limerick when he captured their king, Amlaíb Cenncairech, in 937. That same year he allied with Constantine II of Scotland in an attempt to reclaim the Kingdom of Northumbria which his father had ruled briefly in 927. The forces of Olaf and Constantine were defeated by the English led by Æthelstan at the Battle of Brunanburh in 937.

Olaf returned to Ireland in 938 but after Æthelstan's death the following year Olaf left for York where he was quickly able to establish himself as king, with his brother Blácaire mac Gofraid being left to rule in Dublin. Olaf and Æthelstan's successor Edmund met in 939 at Leicester where they came to an agreement regarding the division of England between them. This agreement proved short-lived, however, and within a few years Vikings had occupied the Five Boroughs of Derby, Leicester, Lincoln, Nottingham and Stamford. Olaf died in 941 and was succeeded in Northumbria by his cousin Olaf Cuaran. At the time of his death, the Irish annals title him "king of Danes" and "king of the Fair Foreigners and the Dark Foreigners".

Sitric Cáech or Sihtric Cáech or Sigtrygg Gále, (Old Norse: Sigtryggr [ˈsiɣˌtryɡːz̠], Old English: Sihtric, died 927) was a Hiberno-Scandinavian Viking leader who ruled Dublin and then Viking Northumbria in the early 10th century. He was a grandson of Ímar and a member of the Uí Ímair. Sitric was most probably among those Vikings expelled from Dublin in 902, whereafter he may have ruled territory in the eastern Danelaw in England. In 917, he and his kinsman Ragnall ua Ímair sailed separate fleets to Ireland where they won several battles against local kings. Sitric successfully recaptured Dublin and established himself as king, while Ragnall returned to England to become King of Northumbria. In 919, Sitric won a victory at the Battle of Islandbridge over a coalition of local Irish kings who aimed to expel the Uí Ímair from Ireland. Six Irish kings were killed in the battle, including Niall Glúndub, overking of the Northern Uí Néill and High King of Ireland.

In 920 Sitric left Dublin for Northumbria, with his kinsman Gofraid ua Ímair succeeding him as king in Dublin. That same year Sitric led a raid on Davenport, Cheshire, perhaps as an act of defiance against Edward the Elder, King of the Anglo-Saxons. In 921 Ragnall ua Ímair died, with Sitric succeeding him as King of Northumbria. Though there are no written accounts of conflict, numismatic evidence suggests there was a Viking reconquest of a large part of Mercia in the following few years. An agreement of some sort between the Vikings of Northumbria and the Anglo-Saxons was achieved in 926 when Sitric married a sister of Æthelstan, perhaps Edith of Polesworth. Sitric also converted to Christianity, though this did not last long and he soon reverted to paganism. He died in 927 and was succeeded by his kinsman Gofraid ua Ímair. Sitric's son Gofraid later reigned as king of Dublin, his son Aralt (Harald) as king of Limerick, and his son Amlaíb Cuarán as king of both Dublin and Northumbria.

Owain ap Dyfnwal (fl. 934) was an early tenth-century King of Strathclyde. He was probably a son of Dyfnwal, King of Strathclyde, who may have been related to previous rulers of the Kingdom of Strathclyde. Originally centred in the valley of the River Clyde, this realm appears to have undergone considerable southward expansion in the ninth or tenth century, after which it increasingly came to be known as the Kingdom of Cumbria.

Owain may have represented the Cumbrians in the tripartite alliance with the kingdoms of Alba and Mercia, assembled by Æthelflæd, Lady of the Mercians in the second decade of the tenth century. Around this time, the Cumbrians are recorded to have campaigned against either Ragnall ua Ímair or Sitric Cáech. Owain may also be the king of Strathclyde who is recorded to have submitted to Æthelflæd's brother, Edward, King of the Anglo-Saxons, in 920 with Ragnall and Custantín mac Áeda, King of Alba. Moreover, Owain seems to have been present at another assembly in 927, when he, Custantín, Ealdred (son of Eadwulf), and perhaps Owain ap Hywel, King of Gwent, acknowledged overlordship of Edward's son and successor, Æthelstan. This assembly may have been held on or near the River Eamont, seemingly the southern frontier of the Cumbrian kingdom.

The English king Æthelstan invaded Scotland by land and sea with a large force in AD 934. No record of any battles fought during the invasion has survived and Æthelstan returned to England later in the year.
