Life
Contemporary sources tell us very little about her life. The only primary sources that reveals her name is in King Alfred’s Will. Within this Will, she is the last beneficiary listed. Alfred grants her estates at Lambourn, Wantage, and Edington, along with one hundred pounds of gold. However, Alfred does not mention his three daughters by name or his youngest son, with Edward, his eldest son, being the only child named.
Asser was a Welsh monk who lived during the same time as Alfred, and he learned and taught at St. David’s in Wales. He was a scholar who would translate works of literature within St. David. The origins as to how Asser and Alfred met are unknown, but it is believed that they were at the same meeting after Alfred took control of the Welsh land. Asser would spend prolonged months with Alfred, translating works of literature for him and it was Alfred who approached Asser to write his biography, The Life of King Alfred. Within this biography, Asser writes about the genealogies of both Ealhswith and her mother, Eadburh. The Mercian kings Ealhswith hailed from were on Eadburh's side of the family. However, Asser only mentions Eadburh by name and does not call Ealhswith by her own name. Instead, he refers to her as “a noble Mercian Lady” and that she was a “chaste widow” after the death of Alfred. It is unknown why Asser omitted Ealhswith's name from the text, but chose to include her mother's.
In recent history, authors have cited Ealhswith by name more frequently and acknowledged her accomplishments. In Alex Traves, Genealogy and royal women in Asser’s Life of King Alfred: politics, prestige, and maternal kinship in early medieval England, he highlights her significance to Alfred and that she was an ideal bride for him in terms of the lineage tied to her. Her importance to Alfred was showcased by Traves, giving her credit for being one of the contributing factors to Alfred inheriting the throne. Traves and other modern authors give her recognition for her contributions to the English throne compared to Ealhswith's contemporaries.
She was married to Alfred in 868. His elder brother Æthelred was then king, and according to Asser, Alfred was regarded as heir apparent. The Danes occupied the Mercian town of Nottingham in that year and her marriage to King Alfred was seen as political leverage. Alfred inherited the throne after his brothers death in 871. In accordance with ninth century West Saxon custom, she was not granted the title of queen. According to King Alfred, this was due to a crime committed by a former queen of the West Saxons, Eadburh, who had attempted to poison an enemy and accidentally killed her husband King Beorhtric instead in 802. Ealhswith had two sons and three daughters who survived to adulthood.
She did not witness any surviving charters during Alfred's lifetime. After his death, in 901, Ealhswith did witness one charter during the reign of her son King Edward in which she is identified as "Ealhswið mater regis", Ealhswith mother of the king. Her name is subscribed immediately after King Edward, and before Edward's wife Ælfflæd.
Alfred left his wife three important symbolic estates in his will, Edington in Wiltshire, the site of one important victory over the Vikings, Lambourn in Berkshire, which was near another, and Wantage, his birthplace. These were all part of his bookland, and they stayed in royal possession after her death.
Ealhswith died on 5 December 902, and was buried in her son Edward's new Benedictine abbey, the New Minster, Winchester. Edward also had his father, Alfred, moved to New Minster, Winchester. She is commemorated in two early tenth century manuscripts as "the true and dear lady of the English".
