Æthelred the Unready Æthelred the Unready Æthelred II (Old English: "Æþelræd", ; 966 – 23 April 1016), known as the Unready, was King of the English from 978 to 1013 and again from 1014 until his death. His epithet does not derive from the modern word "unready", but rather from the Old English "unræd" (meaning "poorly advised"); it is a pun on his name, which means "well advised". Æthelred was the son of King Edgar and Queen Ælfthryth. He came to the throne at about the age of 12, following the assassination of his older half-brother, Edward the Martyr. His brother's murder was
Edgar, King of Scotland uncle Donald III (Domnall Bán mac Donnchada). His older brother Edmund sided with Donald, presumably in return for an appanage and acknowledgement as the heir of the aged and son-less Donald. Edgar received limited support from William II (William Rufus) as Duncan had before him; however, the English king was occupied with a revolt led by Robert de Mowbray, Earl of Northumbria, who appears to have had the support of Donald and Edmund. Rufus campaigned in northern England for much of 1095, and during this time Edgar gained control only of Lothian. A charter issued at Durham at this time
