A History of the British Monarchy/Saxon Rulers/Edmund I the Elder
Edward the Elder succeeded Alfred the great as the King of the Anglo-Saxons.
As a son of a king, Edward was an ætheling, a prince of the royal house who was eligible for kingship. Even though he had the advantage of being the eldest son of the reigning king, his accession was not assured as he had cousins who had a strong claim to the throne. Æthelhelm and Æthelwold were sons of Æthelred, Alfred's older brother and predecessor as king, but they had been passed over because they were infants when their father died. Asser gives more information about Edward's childhood and youth than is known about other Anglo-Saxon princes, providing details about the training of a prince in a period of Carolingian influence, and Yorke suggest that we may know so much due to Alfred's efforts to portray his son as the most throneworthy ætheling.
