later than 993 when he was a signatory to charters along with his two elder brothers. He was the third of the six sons of King Æthelred the Unready and his first wife, Ælfgifu, who was probably the daughter of Earl Thored of Northumbria. His elder brothers were Æthelstan (died 1014) and Egbert (died c. 1005), and younger ones, Eadred, Eadwig and Edgar. He had four sisters, Eadgyth (or Edith), Ælfgifu, Wulfhilda, and the Abbess of Wherwell Abbey. His mother died around 1000, after which his father remarried, this time to Emma of Normandy, who had two sons, Edward the Confessor and Alfred and a daughter Goda. Æthelstan and Edmund were close, and they probably felt threatened by Emma's ambitions for her sons. The Life of Edward the Confessor, written fifty years later, claimed that when Emma was pregnant with him, all Englishmen promised that if the child was a boy they would accept him as king. Warrior prince When Sweyn Forkbeard seized the throne at the end of 1013 and Æthelred fled to Normandy, the brothers do not appear to have followed him, but stayed in England. Æthelstan died in June 1014 and left Edmund a sword which had belonged to king Offa of Mercia. His will also reflected the close relationship between the brothers and the nobility of the East Midlands. Sweyn died in February 1014, and the Five Boroughs accepted his son Cnut as king. However, Æthelred returned to England and launched a surprise attack which defeated the Vikings and forced Cnut to flee England. In 1015 Sigeferth and Morcar came to an assembly in Oxford, probably hoping for a royal pardon, but they were murdered by Eadric Streona. King Æthelred then ordered that Sigeferth's widow, Ealdgyth, be seized and brought to Malmesbury Abbey, but Edmund seized and married her in defiance of his father, probably to consolidate his power base in the East Midlands. He then received the submission of the people of the Five Boroughs. At the same time, Cnut launched a new invasion of England. In late 1015 Edmund raised an army, possibly assisted by his wife's and mother's links with the midlands and the north, but the Mercians under Eadric Streona joined the West Saxons in submitting to Cnut. In early 1016 the army assembled by Edmund dispersed when Æthelred did not appear to lead it, probably because of illness. Edmund then raised
