Sir Frank Stenton remarked that "much that has brought condemnation of historians on King Æthelred may well be due in the last resort to the circumstances under which he became king."[7] Æthelred's father, King Edgar, had died suddenly in July 975, leaving two young sons behind. The elder, Edward (later Edward the Martyr), was probably illegitimate,[8] and was "still a youth on the verge of manhood" in 975.[9] The younger son was Æthelred, whose mother, Ælfthryth, Edgar had married in 964. Ælfthryth was the daughter of Ordgar, ealdorman of Devon, and widow of Æthelwold, Ealdorman of East Anglia. At the time of his father's death, Æthelred could have been no more than 10 years old. As the elder of Edgar's sons, Edward – reportedly a young man given to frequent violent outbursts – probably would have naturally succeeded to the throne of England despite his young age, had not he "offended many important persons by his intolerable violence of speech and behaviour."[9] In any case, a number of English nobles took to opposing Edward's succession and to defending Æthelred's claim to the throne; Æthelred was, after all, the son of Edgar's last, living wife, and no rumour of illegitimacy is known to have plagued Æthelred's birth, as it might have his elder brother's.[10] Both boys, Æthelred certainly, were too young to have played any significant part in the political manoeuvring which followed Edgar's death. It was the brothers' supporters, and not the brothers themselves, who were responsible for the turmoil which accompanied the choice of a successor to the throne. Æthelred's cause was led by his mother and included Ælfhere, Ealdorman of Mercia and Bishop Æthelwold of Winchester,[11] while Edward's claim was supported by Dunstan, the Archbishop of Canterbury and Saint Oswald of Worcester, the Archbishop of York[12] among other noblemen, notably Æthelwine, Ealdorman of East Anglia, and Byrhtnoth, ealdorman of Essex. In the end, Edward's supporters proved the more powerful and persuasive, and he was crowned king at Kingston upon Thames before the year was out. Edward reigned for only three years before he was murdered by members of his brother's household.[13] Though we know little about Edward's short reign, we do know that it was marked by political turmoil. Edgar had made extensive grants of land to monasteries which pursued the new monastic ideals of ecclesiastical reform, but these disrupted aristocratic families' traditional patronage. The end of his firm rule saw a reversal of this policy, with aristocrats recovering their lost properties or seizing new ones. This was opposed by Dunstan, but according to Cyril Hart, "The presence of supporters of church reform on both sides indicates that the conflict between them depended as much on issues of land ownership and local power as on ecclesiastical legitimacy. Adherents of both Edward and Æthelred can be seen appropriating, or recovering, monastic lands."[8] Nevertheless, favour for Edward must have been strong among the monastic communities. When Edward was killed at Æthelred's estate at Corfe Castle in Dorset in March 978, the job of recording the event, as well as reactions to it, fell to monastic writers. Stenton offers a summary of the earliest account of Edward's murder, which comes from a work praising the life of Saint Oswald of Worcester: "On the surface his [Edward's] relations with Æthelred his half-brother and Ælfthryth his stepmother were friendly, and he was visiting them informally when he was killed. [Æthelred's] retainers came out to meet him with ostentatious signs of respect, and then, before he had dismounted, surrounded him, seized his hands, and stabbed him. ... So far as can be seen the murder was planned and carried out by Æthelred's household men in order that their young master might become king. There is nothing to support the allegation, which first appears in writing more than a century later, that Queen Ælfthryth had plotted her stepson's death. No one was punished for a part in the crime, and Æthelred, who was crowned a month after the murder, began to reign in an atmosphere of suspicion which destroyed the prestige of the crown. It was never fully restored in his lifetime."[14] Nevertheless, at first, the outlook of the new king's officers and counsellors seems in no way to have been bleak. According to one chronicler, the coronation of Æthelred took place with much rejoicing by the councillors of the English people.[15] Simon Keynes notes that "Byrhtferth of Ramsey states similarly that when Æthelred was consecrated king, by Archbishop Dunstan and Archbishop Oswald, 'there was great joy at his consecration’, and describes the king in this connection as 'a young man in respect of years, elegant in his manners, with an attractive face and handsome appearance'."[15] Æthelred could not have been older than 13 years of age in this year. During these early years, Æthelred was developing a close relationship to Æthelwold, bishop of Winchester, one who had supported his unsuccessful claim to the throne. When Æthelwold died, on 1 August 984, Æthelred deeply lamented the loss, and he wrote later in a charter from 993 that the event had deprived the country of one "whose industry and pastoral care administered not only to my interest but also to that of all inhabitants of the country."[15]
