Edward the Elder in the context of "Battle of Edington"

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.

Æthelred I (alt. Aethelred, Ethelred; Old English: Æthel-ræd, lit. 'noble counsel'; 845/848 to 871) was King of Wessex from 865 until his death in 871. He was the fourth of five sons of King Æthelwulf of Wessex, four of whom in turn became king. Æthelred succeeded his elder brother Æthelberht and was followed by his youngest brother, Alfred the Great. Æthelred had two sons, Æthelhelm and Æthelwold, who were passed over for the kingship on their father's death because they were still infants. Alfred was succeeded by his son, Edward the Elder, and Æthelwold unsuccessfully disputed the throne with him.

Æthelred's accession coincided with the arrival of the Viking Great Heathen Army in England. Over the next five years the Vikings conquered Northumbria and East Anglia, and at the end of 870 they launched a full-scale attack on Wessex. In early January 871, Æthelred was defeated at the Battle of Reading. Four days later, he scored a victory in the Battle of Ashdown, but this was followed by two defeats at Basing and Meretun. He died shortly after Easter. Alfred was forced to pay off the Vikings, but he scored a decisive victory over them seven years later at the Battle of Edington.

Æthelstan or Athelstan (/ˈæθəlstæn/; Old English: Æðelstān [ˈæðelstɑːn]; Old Norse: Aðalsteinn; lit. 'noble stone'; c. 894 – 27 October 939) was King of the Anglo-Saxons from 924 to 927 and King of the English from 927 to his death in 939. He was the son of King Edward the Elder and his first wife, Ecgwynn. Modern historians regard him as the first King of England and one of the "greatest Anglo-Saxon kings". He never married and had no children; he was succeeded by his half-brother, Edmund I.

When Edward died in July 924, Æthelstan was accepted by the Mercians as king. His half-brother Ælfweard may have been recognised as king in Wessex, but died within three weeks of their father's death. Æthelstan encountered resistance in Wessex for several months, and was not crowned until September 925. In 927, he conquered the last remaining Viking kingdom, York, making him the first Anglo-Saxon ruler of the whole of England. In 934, he invaded Scotland and forced Constantine II to submit to him. Æthelstan's rule was resented by the Scots and Vikings, and in 937 they invaded England. Æthelstan defeated them at the Battle of Brunanburh, a victory that gave him great prestige both in the British Isles and on the Continent. After his death in 939, the Vikings seized back control of York, and it was not finally reconquered until 954.

Æthelwold (/ˈæθəlwoʊld/) or Æthelwald (died 13 December 902) was the younger of two known sons of Æthelred I, King of Wessex from 865 to 871. Æthelwold and his brother Æthelhelm were still infants when their father the king died while fighting a Danish Viking invasion. The throne passed to the king's younger brother (Æthelwold's uncle) Alfred the Great, who carried on the war against the Vikings and won a crucial victory at the Battle of Edington in 878.

After Alfred's death in 899, Æthelwold disputed the throne with Alfred's son, Edward the Elder. As senior ætheling (prince of the royal dynasty eligible for kingship), Æthelwold had a strong claim to the throne. He attempted to raise an army to support his claim, but was unable to get sufficient support to meet Edward in battle and fled to Viking-controlled Northumbria, where he was accepted as king. In 901 or 902 he sailed with a fleet to Essex, where he was also accepted as king.

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.

Ealhswith or Ealswitha (died 5 December 902) was the wife of King Alfred the Great. She was the mother of King Edward the Elder who succeeded King Alfred to the Anglo-Saxon throne. Her father was a Mercian nobleman, Æthelred Mucel, Ealdorman of the Gaini, which is thought to be an old Mercian tribal group. Her mother was Eadburh, a member of the Mercian royal family and her lineage was one of the primary reasons for Alfred taking Ealhswith as his wife. She founded the nunnery of Nunnaminster.

Æthelred (died 911) became Lord of the Mercians in England shortly after the death or disappearance of Mercia's last king, Ceolwulf II, in 879. He is also sometimes called the Ealdorman of Mercia. Æthelred's rule was confined to the western half, as eastern Mercia was then part of the Viking-ruled Danelaw. His ancestry is unknown. He was probably the leader of an unsuccessful Mercian invasion of Wales in 881, and soon afterwards he acknowledged the lordship of King Alfred the Great of Wessex. This alliance was cemented by the marriage of Æthelred to Alfred's daughter Æthelflæd.

In 886, Alfred took possession of London, which had suffered greatly from several Viking occupations. Alfred then handed London over to Æthelred, as it had traditionally been a Mercian town. In 892, the Vikings renewed their attacks, and the following year, Æthelred led an army of Mercians, West Saxons and Welsh to victory over a Viking army at the Battle of Buttington. He spent the next three years fighting them alongside Alfred's son, the future King Edward the Elder. At some time after 899 Æthelred's health may have declined, and Æthelflæd may have become the effective ruler of Mercia.

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.
