Anglo-Saxon kings ruled through [[ealdorman|ealdormen]], who had the highest lay status under the king. In ninth-century Wessex they each ruled a single shire, but by the middle of the tenth they had authority over a much wider area, a change probably introduced by Æthelstan to deal with the problems of governing his extended realm.{{Sfnm|1a1=John|1y=1982|1p=172|2a1=Stafford|2y=2014|2pp=156–157}} One of the ealdormen, who was also called [[Æthelstan Half-King|Æthelstan]], governed the eastern Danelaw territory of East Anglia, the largest and wealthiest province of England. He became so powerful that he was later known as Æthelstan Half King.{{Sfn|Hart|1992|p=575}} Several of the ealdormen who witnessed charters had Scandinavian names, and while the localities they came from cannot be identified, they were almost certainly the successors of the earls who led Danish armies in the time of Edward the Elder, and who were retained by Æthelstan as his representatives in local government.{{Sfn|Foot|2011|p=129}}

Beneath the ealdormen, reeves—royal officials who were noble local landowners—were in charge of a town or royal estate. The authority of church and state was not separated in early medieval societies, and the lay officials worked closely with their diocesan bishop and local abbots, who also attended the king's royal councils.{{Sfn|Foot|2011|p=130}}

As the first king of all the Anglo-Saxon peoples, Æthelstan needed effective means to govern his extended realm. Building on the foundations of his predecessors, he created the most centralised government that England had yet seen.{{Sfn|Foot|2011|p=10}} Previously, some charters had been produced by royal priests and others by members of religious houses, but between 928 and 935 they were produced exclusively by a scribe known to historians as "[[Æthelstan A]]", showing an unprecedented degree of royal control over an important activity. Unlike earlier and later charters, "Æthelstan A" provides full details of the date and place of adoption and an unusually long witness list, providing crucial information for historians. After "Æthelstan A" retired or died, charters reverted to a simpler form, suggesting that they had been the work of an individual, rather than the development of a formal writing office.{{Sfn|Foot|2011|pp=71–72}}

A key mechanism of government was the king's council (''[[witan]]'' in Old English).{{Sfn|Yorke|2014|pp=126–127}} Anglo-Saxon kings did not have a fixed capital city. Their courts were peripatetic, and their councils were held at varying locations around their realms. Æthelstan stayed mainly in Wessex, however, and controlled outlying areas by summoning leading figures to his councils. The small and intimate meetings that had been adequate until the enlargement of the kingdom under Edward the Elder gave way to large bodies attended by bishops, ealdormen, [[thegn]]s, magnates from distant areas, and independent rulers who had submitted to his authority. [[Frank Stenton]] sees Æthelstan's councils as "national assemblies", which did much to break down the provincialism that was a barrier to the unification of England. John Maddicott goes further, seeing them as the start of centralised assemblies that had a defined role in English government, and Æthelstan as "the true if unwitting founder of the English parliament".{{Sfnm|1a1=Foot|1y=2011|1pp=63, 77–79|2a1=Stenton|2y=1971|2p=352|3a1=Maddicott|3y=2010|3p=4}}

=== Law ===
The Anglo-Saxons were the first people in northern Europe to write administrative documents in the vernacular, and law codes in Old English go back to [[Æthelberht of Kent]] at the beginning of the seventh century. The law code of Alfred the Great, from the end of the ninth century, was also written in the vernacular, and he expected his [[ealdormen]] to learn it.{{Sfn|Foot|2011|p=136}} His code was strongly influenced by [[Carolingian]] law going back to [[Charlemagne]] in such areas as treason, peace-keeping, organisation of the [[Hundred (county division)|hundreds]] and [[Trial by ordeal|judicial ordeal]].{{Sfn|Pratt|2010|p=332}} It remained in force throughout the tenth century, and Æthelstan's codes were built on this foundation.{{Sfn|Keynes|1999|p=471}} Legal codes required the approval of the king, but they were treated as guidelines which could be adapted and added to at the local level, rather than a fixed canon of regulations, and customary oral law was also important in the Anglo-Saxon period.{{Sfnm|1a1=Roach|1y=2013|1pp=477–479|2a1=Foot|2y=2011|2pp=136–137}}

More legal texts survive from Æthelstan's reign than from any other tenth-century English king. The earliest appear to be his tithe edict and the "Ordinance on Charities". Four legal codes were adopted at Royal Councils in the early 930s at [[Grateley]] in Hampshire, Exeter, [[Faversham]] in Kent, and Thunderfield in Surrey. Local legal texts survive from London and Kent, and one concerning [[Archenfield|the 'Dunsæte']] on the Welsh border probably also dates to Æthelstan's reign.{{Sfnm|1a1=Pratt|1y=2010|1pp=335–336, 345–346|2a1=Foot|2y=2011|2pp=299–300}} In the view of the historian of English law [[Patrick Wormald]], the laws must have been written by [[Wulfhelm]], who succeeded Athelm as Archbishop of Canterbury in 926.{{Sfn|Wormald|1999|pp=299–300}}{{Efn|Wormald discusses the codes in detail in ''The Making of English Law''.{{Sfn|Wormald|1999|pp=290–308, 430–440}} }} Other historians see Wulfhelm's role as less important, giving the main credit to Æthelstan himself, although the significance placed on the ordeal as an ecclesiastical ritual shows the increased influence of the church. [[Nicholas Brooks (historian)|Nicholas Brooks]] sees the role of the bishops as marking an important stage in the increasing involvement of the church in the making and enforcement of law.{{Sfnm|1a1=Foot|1y=2011|1pp=138, 146–148|2a1=Pratt|2y=2010|2pp=336, 350|3a1=Keynes|3y=1999|3p=471|4a1=Brooks|4y=1984|4p=218}}

The two earliest codes were concerned with clerical matters, and Æthelstan stated that he acted on the advice of Wulfhelm and his bishops. The first asserts the importance of paying tithes to the church. The second enforces the duty of charity on Æthelstan's reeves, specifying the amount to be given to the poor and requiring reeves to free one penal slave annually. His religious outlook is shown in a wider sacralisation of the law in his reign.{{Sfn|Foot|2011|pp=136–140, 146–147}}

The later codes show his concern with threats to social order, especially robbery, which he regarded as the most important manifestation of social breakdown. The first of these later codes, issued at Grateley, prescribed harsh penalties, including the death penalty for anyone over twelve years old caught in the act of stealing goods worth more than eight pence. This apparently had little effect, as Æthelstan admitted in the Exeter code: "I King Æthelstan, declare that I have learned that the public peace has not been kept to the extent, either of my wishes, or of the provisions laid down at Grateley, and my councillors say that I have suffered this too long." In desperation the Council tried a different strategy, offering an amnesty to thieves if they paid compensation to their victims. The problem of powerful families protecting criminal relatives was to be solved by expelling them to other parts of the realm. This strategy did not last long, and at Thunderfield Æthelstan returned to the hard line, softened by raising the minimum age for the death penalty to fifteen "because he thought it too cruel to kill so many young people and for such small crimes as he understood to be the case everywhere".{{Sfn|Foot|2011|pp=140–142}} His reign saw the first introduction of the system of [[tithing]], sworn groups of ten or more men who were jointly responsible for peacekeeping (later known as [[frankpledge]]). Sarah Foot commented that tithing and oath-taking to deal with the problem of theft had its origin in Frankia: "But the equation of theft with disloyalty to Æthelstan's person appears peculiar to him. His preoccupation with theft—tough on theft, tough on the causes of theft—finds no direct parallel in other kings' codes."{{Sfnm|1a1=Pratt|1y=2010|1pp=339–347|2a1=Foot|2y=2011|2pp=143–145}}

Historians differ widely regarding Æthelstan's legislation. Patrick Wormald's verdict was harsh: "The hallmark of Æthelstan's law-making is the gulf dividing its exalted aspirations from his spasmodic impact." In his view, "The legislative activity of Æthelstan's reign has rightly been dubbed 'feverish'{{Nbsp}}... But the extant results are, frankly, a mess.{{Sfn|Wormald|1999|pp=300, 308}} In the view of Simon Keynes, however, "Without any doubt the most impressive aspect of King Æthelstan's government is the vitality of his law-making", which shows him driving his officials to do their duties and insisting on respect for the law, but also demonstrates the difficulty he had in controlling a troublesome people. Keynes sees the Grateley code as "an impressive piece of legislation" showing the king's determination to maintain social order.{{Sfn|Pratt|2010|p=349}}

=== Coinage ===
[[File:Athelstan 924-939 coin.jpg|thumb|Coin of ''Æthelstan Rex'', small [[cross pattée]] type, London mint, moneyer Biorneard|alt=refer to caption]]

In the 970s, Æthelstan's nephew, [[Edgar the Peaceful|King Edgar]], reformed the monetary system to give Anglo-Saxon England the most advanced currency in Europe, with a good quality silver coinage, which was uniform and abundant.{{Sfnm|1a1=Campbell|1y=2000|1pp=32–33, 181|2a1=Foot|2y=2011|2p=152}} In Æthelstan's time, however, it was far less developed, and [[Mint (coin)|minting]] was still organised regionally long after Æthelstan unified the country. The Grately code included a provision that there was to be only one [[History of the English penny (c. 600 – 1066)|coinage]] across the king's dominion. However, this is in a section that appears to be copied from a code of his father, and the list of towns with mints is confined to the south, including London and Kent, but not northern Wessex or other regions. Early in Æthelstan's reign, different styles of coin were issued in each region, but after he conquered York and received the submission of the other British kings, he issued a new coinage, known as the "circumscription cross" type. This advertised his newly exalted status with the inscription, "Rex Totius Britanniae". Examples were minted in Wessex, York, and English Mercia (in Mercia bearing the title "Rex Saxorum"), but not in East Anglia or the Danelaw.{{Sfn|Foot|2011|pp=151–155}}

In the early 930s a new coinage was issued, the "crowned bust" type, with the king shown for the first time wearing a crown with three stalks. This was eventually issued in all regions apart from Mercia, which issued coins without a ruler portrait, suggesting, in Sarah Foot's view, that any Mercian affection for a West Saxon king brought up among them quickly declined.{{Sfn|Foot|2011|pp=155–156}}

=== Church ===
[[File:Coronation Gospels Athelstan Saint Matthew.jpg|thumb|upright=1.25|Miniature of St Matthew in the Carolingian gospels presented by Æthelstan to [[Christ Church Priory]], Canterbury; now in the [[British Library]], London|alt=refer to caption]]

Church and state maintained close relations in the Anglo-Saxon period, both socially and politically. Churchmen attended royal feasts as well as meetings of the Royal Council. During Æthelstan's reign these relations became even closer, especially as the archbishopric of Canterbury had come under West Saxon jurisdiction since Edward the Elder annexed Mercia, and Æthelstan's conquests brought the northern church under the control of a southern king for the first time.{{Sfn|Foot|2011|pp=95–96}}

Æthelstan appointed members of his own circle to bishoprics in Wessex, possibly to counter the influence of the Bishop of Winchester, Frithestan. One of the king's mass-priests (priests employed to say Mass in his household), [[Alphege of Wells|Ælfheah]], became [[Bishop of Wells]], while another, [[Beornstan of Winchester|Beornstan]], succeeded Frithestan as Bishop of Winchester. Beornstan was succeeded by another member of the royal household, also called [[Ælfheah the Bald|Ælfheah]].{{Sfn|Foot|2011|p=97}} Two of the leading figures in the later tenth-century [[English Benedictine Reform|Benedictine monastic reform]] in Edgar's reign, Dunstan and [[Æthelwold of Winchester|Æthelwold]], served in early life at Æthelstan's court and were ordained as priests by Ælfheah of Winchester at the king's request.{{Sfnm|1a1=Lapidge|1y=2004|2a1=Yorke|2y=2004}} According to Æthelwold's biographer, [[Wulfstan the Cantor|Wulfstan]], "Æthelwold spent a long period in the royal palace in the king's inseparable companionship and learned much from the king's wise men that was useful and profitable to him".{{Sfn|Wood|2010|pp=148–149}} [[Oda of Canterbury|Oda]], a future Archbishop of Canterbury, was also close to Æthelstan, who appointed him [[Bishop of Ramsbury (ancient)|Bishop of Ramsbury]].{{Sfn|Foot|2011|pp=97–98, 215}} Oda may have been present at the battle of Brunanburh.{{Sfn|Cubitt|Costambeys|2004}}

Æthelstan was a noted collector of relics, and while this was a common practice at the time, he was marked out by the scale of his collection and the refinement of its contents.{{Sfn|Brooke|2001|p=115}} The abbot of Saint Samson in [[Ancient Diocese of Dol|Dol]] sent him some as a gift, and in his covering letter he wrote: "we know you value relics more than earthly treasure".{{Sfn|Nelson|1999b|p=112}} Æthelstan was also a generous donor of manuscripts and relics to churches and monasteries. His reputation was so great that some monastic scribes later falsely claimed that their institutions had been beneficiaries of his largesse. He was especially devoted to the cult of [[Cuthbert|St. Cuthbert]] in Chester-le-Street, and his gifts to the community there included [[Bede]]'s Lives of Cuthbert. He commissioned it especially to present to Chester-le Street, and out of all manuscripts he gave to a religious foundation which survive, it is the only one which was wholly written in England during his reign.{{Sfnm|1a1=Foot|1y=2011|1pp=117–124|2a1=Keynes|2y=1985|2p=180}} It has a portrait of Æthelstan presenting the book to Cuthbert, the earliest surviving manuscript portrait of an English king.{{Sfn|Karkov|2004|p=55}} In the view of Janet Nelson, his "rituals of largesse and devotion at sites of supernatural power ... enhanced royal authority and underpinned a newly united imperial realm".{{Sfn|Nelson|1999b|p=112}}

Æthelstan had a reputation for founding churches, although it is unclear how justified this is. According to late and dubious sources, these churches included minsters at [[Milton Abbas]] in Dorset and [[Muchelney Abbey|Muchelney]] in Somerset. In the view of historian John Blair, the reputation is probably well-founded, but "these waters are muddied by Æthelstan's almost folkloric reputation as a founder, which made him a favourite hero of later origin-myths".{{Sfn|Blair|2005|p=348}} However, while he was a generous donor to monasteries, he did not give land for new ones or attempt to revive the ones in the north and east destroyed by Viking attacks.{{Sfn|Foot|2011|pp=135–136}}

He also sought to build ties with continental churches. [[Koenwald|Cenwald]] was a royal priest before his appointment as [[Bishop of Worcester]], and in 929 he accompanied two of Æthelstan's half-sisters to the [[Duchy of Saxony|Saxon court]] so that the future [[Holy Roman Emperor]], [[Otto I, Holy Roman Emperor|Otto]], could choose one of them as his wife. Cenwald went on to make a tour of German monasteries, giving lavish gifts on Æthelstan's behalf and receiving in return promises that the monks would pray for the king and others close to him in perpetuity. England and Saxony became closer after the marriage alliance, and German names start to appear in English documents, while Cenwald kept up the contacts he had made by subsequent correspondence, helping the transmission of continental ideas about reformed monasticism to England.{{Sfn|Foot|2011|pp=101–102}}

=== Learning ===
[[File:Gospel Dice.jpg|thumb|upright=1.2|alt=Gospel Dice|[[Alea evangelii]], a board game played at Æthelstan's court]]
[[File:Charter S416 written by Æthelstan A in 931.jpg|thumb|upright=1.2|Charter S416 of Æthelstan for Wulfgar in 931, written by the scribe "[[Æthelstan A]]"]]

Æthelstan built on his grandfather's efforts to revive ecclesiastical scholarship, which had fallen to a low state in the second half of the ninth century. John Blair described Æthelstan's achievement as "a determined reconstruction, visible to us especially through the circulation and production of books, of the shattered ecclesiastical culture".{{Sfnm|1a1=Blair|1y=2005|1p=348|2a1=Dumville|2y=1992|2p=156}} He was renowned in his own day for his piety and promotion of sacred learning. His interest in education, and his reputation as a collector of books and relics, attracted a cosmopolitan group of ecclesiastical scholars to his court, particularly Bretons and Irish. Æthelstan gave extensive aid to Breton clergy who had fled Brittany following its conquest by the Vikings in 919. He made a confraternity agreement with the clergy of [[Dol Cathedral]] in Brittany, who were then in exile in central France, and they sent him the relics of Breton saints, apparently hoping for his patronage. The contacts resulted in a surge in interest in England for commemorating Breton saints. One of the most notable scholars at Æthelstan's court was [[Israel the Grammarian]], who may have been a Breton. Israel and "a certain Frank" drew a board game called "[[Gospel Dice]]" for an Irish bishop, Dub Innse, who took it home to [[Bangor, County Down|Bangor]]. Æthelstan's court played a crucial role in the origins of the English monastic reform movement.{{Sfnm|1a1=Foot|1y=2011|1pp=94, 99–107, 190–191|2a1=Keynes|2y=1985|2pp=197–98|3a1=Brett|3y=1991|3pp=44–45}}

Few prose narrative sources survive from Æthelstan's reign, but it produced an abundance of poetry, much of it Norse-influenced praise of the King in grandiose terms, such as the Brunanburh poem. Sarah Foot even makes a case that ''[[Beowulf]]'' may have been composed in Æthelstan's circle.{{Sfn|Foot|2011|pp=109–117}}

Æthelstan's court was the centre of a revival of the elaborate [[hermeneutic style]] of later Latin writers, influenced by the West Saxon scholar [[Aldhelm]] ({{circa|639|lk=no}}{{snd}}709), and by early tenth-century French monasticism. Foreign scholars at Æthelstan's court such as Israel the Grammarian were practitioners. The style was characterised by long, convoluted sentences and a predilection for rare words and neologisms.{{Sfnm|1a1=Lapidge|1y=1993|1p=107|2a1=Gretsch|2y=1999|2pp=332–334, 336}} The "Æthelstan A" charters were written in ''hermeneutic'' Latin. In the view of Simon Keynes it is no coincidence that they first appear immediately after the king had for the first time united England under his rule, and they show a high level of intellectual attainment and a monarchy invigorated by success and adopting the trappings of a new political order.{{Sfn|Keynes|1999|p=470}} The style influenced architects of the late tenth-century monastic reformers educated at Æthelstan's court such as Æthelwold and Dunstan, and became a hallmark of the movement.{{Sfn|Gretsch|1999|pp=348–49}} After "Æthelstan A", charters became more simple, but the ''hermeneutic'' style returned in the charters of Eadwig and Edgar.{{Sfn|Foot|2011|pp=72, 214–215}}

The historian [[W. H. Stevenson]] commented in 1898:
<blockquote>The object of the compilers of these charters was to express their meaning by the use of the greatest possible number of words and by the choice of the most grandiloquent, bombastic words they could find. Every sentence is so overloaded by the heaping up of unnecessary words that the meaning is almost buried out of sight. The invocation with its appended clauses, opening with pompous and partly alliterative words, will proceed amongst a blaze of verbal fireworks throughout twenty lines of smallish type, and the pyrotechnic display will be maintained with equal magnificence throughout the whole charter, leaving the reader, dazzled by the glaze and blinded by the smoke, in a state of uncertainty as to the meaning of these frequently untranslatable and usually interminable sentences.{{Sfn|Foot|2011|p=214, quoting an unpublished lecture by Stevenson}}</blockquote>

However, [[Michael Lapidge]] argues that however unpalatable the ''hermeneutic'' style seems to modern taste, it was an important part of late Anglo-Saxon culture, and deserves more sympathetic attention than it has received from modern historians.{{Sfn|Lapidge|1993|p=140}} In the view of historian David Woodman, "Æthelstan A" should "be accorded recognition as an individual author of no little genius, a man who not only overhauled the legal form of the diploma but also had the ability to write Latin that is as enduringly fascinating as it is complex ... In many ways the diplomas of "Æthelstan A" represent the stylistic peak of the Anglo-Saxon diplomatic tradition, a fitting complement to Æthelstan's own momentous political feats and to the forging of what would become England."{{Sfn|Woodman|2013|p=247}}

=== British monarch ===
[[File:Athelstan from All Souls College Chapel.jpg|thumb|Æthelstan in a fifteenth-century stained glass window in [[All Souls College, Oxford|All Souls College Chapel, Oxford]]|alt=refer to caption]]

Historians frequently comment on Æthelstan's grand and extravagant titles. On his coins and charters he is described as ''Rex totius Britanniae'', or "King of the whole of Britain". A gospel book he donated to [[Christ Church, Canterbury]] is inscribed "Æthelstan, king of the English and ruler of the whole of Britain with a devout mind gave this book to the primatial see of Canterbury, to the church dedicated to Christ". In charters from 931 he is "king of the English, elevated by the right hand of the almighty to the throne of the whole kingdom of Britain", and in one manuscript dedication he is even styled "[[basileus]] et curagulus", the titles of [[Byzantine Empire|Byzantine emperors]].{{Sfnm|1a1=Foot|1y=2011|1pp=212–213|2a1=Ortenberg|2y=2010|2p=215}} Some historians are not impressed. "Clearly", comments Alex Woolf, "King Æthelstan was a man who had pretensions,"{{Sfn|Woolf|2007|p=158}} while in the view of Simon Keynes, "Æthelstan A" proclaimed his master king of Britain "by wishful extension".{{Sfn|Keynes|2001|p=61}} But according to George Molyneaux "this is to apply an anachronistic standard: tenth-century kings had a loose but real hegemony throughout the island, and their titles only appear inflated if one assumes that kingship ought to involve domination of an intensity like that seen within the English kingdom of the eleventh and later centuries."{{Sfn|Molyneaux|2015|p=211}}

=== European relations ===
The West Saxon court had connections with the [[Carolingians]] going back to the marriage between Æthelstan's great-grandfather [[Æthelwulf of Wessex|Æthelwulf]] and [[Judith of Flanders|Judith]], daughter of the king of West Francia (and future Holy Roman Emperor) [[Charles the Bald]], as well as the marriage of Alfred the Great's daughter [[Ælfthryth, Countess of Flanders|Ælfthryth]] to Judith's son by a later marriage, [[Baldwin II, Count of Flanders]]. One of Æthelstan's half-sisters, [[Eadgifu of Wessex|Eadgifu]], married [[Charles the Simple]], king of the [[West Franks]], in the late 910s. He was deposed in 922, and Eadgifu sent their son [[Louis IV of France|Louis]] to safety in England. By Æthelstan's time the connection was well established, and his coronation was performed with the Carolingian ceremony of anointment, probably to draw a deliberate parallel between his rule and Carolingian tradition.{{Sfnm|1a1=Ortenberg|1y=2010|1pp=211–215|2a1=Foot|2y=2011|2p=46}} His "crowned bust" coinage of 933–938 was the first Anglo-Saxon coinage to show the king crowned, following Carolingian iconography.{{Sfn|Karkov|2004|pp=66–67}}

Like his father, Æthelstan was unwilling to marry his female relatives to his own subjects, so his sisters either entered nunneries or married foreign husbands. This was one reason for his close relations with European courts, and he married several of his half-sisters to European nobles{{Sfn|Foot|2011|pp=xv, 44–45}} in what historian Sheila Sharp called "a flurry of dynastic bridal activity unequalled again until Queen Victoria's time".{{Sfn|Sharp|1997|p=198}} Another reason lay in the common interest on both sides of the Channel in resisting the threat from the Vikings, while the rise in the power and reputation of the royal house of Wessex made marriage with an English princess more prestigious to European rulers.{{Sfnm|1a1=Ortenberg|1y=2010|1pp=217–218|2a1=Sharp|2y=2001|2p=82}} In 926 [[Hugh the Great|Hugh]], Duke of the Franks, sent Æthelstan's cousin, Adelolf, Count of Boulogne, on an embassy to ask for the hand of one of Æthelstan's sisters. According to William of Malmesbury, the gifts Adelolf brought included spices, jewels, many swift horses, a crown of solid gold, the sword of [[Constantine the Great]], Charlemagne's lance, and a piece of the [[Crown of Thorns]]. Æthelstan sent his half-sister [[Eadhild]] to be Hugh's wife.{{Sfnm|1a1=Foot|1y=2011|1pp=46–49, 192–193|2a1=Ortenberg|2y=2010|2pp=218–219}}

Æthelstan's most important European alliance was with the new [[Liudolfing]] dynasty in [[East Francia]]. The Carolingian dynasty of East Francia had died out in the early tenth century, and its new Liudolfing king, [[Henry the Fowler]], was seen by many as an ''arriviste''. He needed a royal marriage for his son to establish his legitimacy, but no suitable Carolingian princesses were available. The ancient royal line of the West Saxons provided an acceptable alternative, especially as they (wrongly) claimed descent from the seventh-century king and saint, [[Oswald of Northumbria|Oswald]], who was venerated in Germany. In 929 or 930 Henry sent ambassadors to Æthelstan's court seeking a wife for his son, Otto, who later became Holy Roman Emperor. Æthelstan sent two of his half-sisters, and Otto chose [[Eadgyth]]. Fifty years later, Æthelweard, a descendant of Alfred the Great's older brother, addressed his Latin version of the ''Anglo-Saxon Chronicle'' to [[Mathilde, Abbess of Essen]], who was Eadgyth's granddaughter, and had apparently requested it. The other sister, whose name is uncertain, was married to a prince from near the [[Alps]] who has not definitely been identified.{{Sfnm|1a1=Foot|1y=2011|1pp=xvi, 48–52|2a1=Ortenberg|2y=2010|2pp=231–232|3a1=Nelson|3y=1999b|3p=112|4a1=Wormald|4y=2004}}

In early medieval Europe, it was common for kings to act as foster-fathers for the sons of other kings. Æthelstan was known for the support he gave to dispossessed young royalty. In 936 he sent an English fleet to help his foster-son, [[Alan II, Duke of Brittany]], to regain his ancestral lands, which had been conquered by the Vikings.  In the same year he assisted the son of his half-sister Eadgifu, Louis, to take the throne of West Francia, and in 939 he sent another fleet that unsuccessfully attempted to help Louis in a struggle with rebellious magnates. According to later Scandinavian sources, he helped another possible foster-son, [[Haakon the Good|Hakon]], son of [[Harald Fairhair]], king of [[Norway]], to reclaim his throne,{{Sfn|Foot|2011|pp=22–23, 52–53, 167–168, 167–169, 183–184}} and he was known among Norwegians as "Æthelstan the Good".{{Sfn|Zacher|2011|p=84}}

Æthelstan's court was perhaps the most cosmopolitan of the Anglo-Saxon period.{{Sfn|Zacher|2011|p=82}} The close contacts between the English and European courts ended soon after his death, but descent from the English royal house long remained a source of prestige for continental ruling families.{{Sfn|MacLean|2013|pp=359–361}} According to Frank Stenton in his history of the period, ''Anglo-Saxon England'', "Between Offa and [[Cnut the Great|Cnut]] there is no English king who played so prominent or so sustained a part in the general affairs of Europe."{{Sfn|Stenton|1971|p=344}}

Foreign contemporaries described him in panegyrical terms. The French chronicler [[Flodoard]] described him as "the king from overseas", and the ''Annals of Ulster'' as the "pillar of the dignity of the western world".{{Sfnm|1a1=Ortenberg|1y=2010|1p=211|2a1=Foot|2y=2011|2p=210}} Some historians take a similar view. Michael Wood titled an essay, "The Making of King Aethelstan's Empire: an English Charlemagne?", and described him as "the most powerful ruler that Britain had seen since the Romans".{{Sfn|Wood|1983|p=250}} In the view of Veronica Ortenberg, he was "the most powerful ruler in Europe" with an army that had repeatedly defeated the Vikings; continental rulers saw him as a Carolingian emperor, who "was clearly treated as the new Charlemagne". She wrote:
<blockquote>Wessex kings carried an aura of power and success, which made them increasingly powerful in the 920s, while most Continental houses were in military trouble and engaged in internecine warfare. While the civil wars and the Viking attacks on the Continent had spelled the end of unity of the Carolingian empire, which had already disintegrated into separate kingdoms, military success had enabled Æthelstan to triumph at home and to attempt to go beyond the reputation of a great heroic dynasty of warrior kings, in order to develop a Carolingian ideology of kingship.{{Sfn|Ortenberg|2010|pp=211–222}}</blockquote>
