The details of the succession have been widely debated: the Norman position was that
William had been designated the heir, and that Harold had been publicly sent to him as emissary from Edward, to apprise him of Edward's decision. Harold's party asserted that the old king had made a deathbed bestowal of the crown on Harold. However, Harold was approved by the
Witenagemot who, under
Anglo-Saxon law, held the ultimate authority to convey kingship.
Edward had married Godwin's daughter
Edith on
23 January, 1045, but the union was childless. The reason for this is the subject of much speculation. Possible explanations include Edward, having taken vow of chastity, considering the union a
spiritual marriage, the age difference between Edward and Edith engendering a filial rather than spousal relationship, Edward's antipathy toward Edith's father , or infertility.
Edward's nearest heir would have been his nephew
Edward the Exile, who was born in England, but spent most of his life in Hungary. He had returned from exile in 1056 and died not long after, in February the following year. So Edward made his great nephew
Edgar Atheling his heir. But Edgar had no secure following among the earls: the resultant succession crisis on Edward's death without a direct "throneworthy" heir — the "foreign" Edgar was a stripling of fourteen — opened the way for Harold's coronation and the invasions of two effective claimants to the throne, the unsuccessful invasion of
Harald Hardrada in the north and the successful one of William of Normandy.
William of Normandy, who had visited England during Godwin's exile, claimed that the childless Edward had promised him the succession to the throne, and his
successful bid for the English crown put an end to Harold's nine-month kingship following a 7,000-strong Norman invasion.
Edgar Ætheling was elected king by the
Witan after Harold's death but was brushed aside by William. Edward, or more especially the mediæval cult which would later grow up around him under the later Plantagenet kings, had a lasting impact on English history.
Westminster Abbey was founded by Edward between 1045 and 1050 on land upstream from the City of London, and was consecrated on
28 December, 1065. Centuries later,
Westminster was deemed symbolic enough to become the permanent seat of English government under
Henry III. The Abbey contains a shrine to Edward which was the centrepiece to the Abbey's redesign during the mid-thirteenth century. In 2005, Edward's remains were found beneath the pavement in front of the high altar. His remains had been moved twice in the 12th and 13th centuries, and the original tomb has since been found on the central axis of the Abbey in front of the original high altar.
Historically, Edward's reign marked a transition between the
10th century West Saxon kingship of England and the Norman monarchy which followed Harold's death. Edward's allegiances were split between England and his mother's Norman ties. The great earldoms established under
Canute grew in power, while Norman influence became a powerful factor in government and in the leadership of the
Church.
It was during the reign of Edward that some features of the English monarchy familiar today were introduced. Edward is regarded as responsible for introducing the royal seal and coronation regalia. Also under Edward, a marked change occurred in Anglo-Saxon art, with continental influences becoming more prominent (including the "Winchester Style" which had become known in the 10th century but prominent in the 11th), supplanting Celtic influences prominent in preceding painting, sculpture, calligraphy and jewellery (see
Benedictional of St. Æthelwold for an example of the Winchester Style). His crown is believed to have survived until the
English Civil War when
Oliver Cromwell allegedly ordered it to be destroyed. Gold from it is understood to have been integrated into the
St. Edward's Crown, which has been used in coronations since
Charles II of England in 1661.
