In 1040, Harthacnut was planning an invasion to take back the throne from his half brother, but Harold conveniently died, allowing Harthacnut (and Emma) to sail into England without opposition. One year later, however, Harthacnut invited Edward to England. Harthacnut was only in his twenties, but had not been well for a long time—tuberculosis has been suggested as the cause—and he may have felt he did not have long to live.
With no wife or children, Harthacnut wanted to name a successor, and he chose Edward (se above observing Christ in the Eucharist). According to the Encomium Emmae Reginae ("Encomium [Praise] of Queen Emma"), she was something of a co-ruler with Edward and the ailing Harthacnut.
On 8 June 1042, Harthacnut attended a wedding. The Anglo-Saxon Chronicle reports:
Harthacnut died as he stood at his drink, and he suddenly fell to the earth with an awful convulsion; and those who were close by took hold of him, and he spoke no word afterwards.
Edward was supported by Godwin, Earl of Wessex (who had earlier been hostile to Edward's cause, capturing and blinding Edward's brother and causing his death). Edward was crowned on Easter Sunday, 3 April 1043. One of his first acts was to deprive his mother of all her property (which was extensive).
Confiscating her property was good for Edward, but he was still less powerful in real terms than his three leading earls: Godwin of Wessex, Leofric of Mercia, Siward of Northumbria. Also, Edward was a return of the throne to an English ruler, whereas the past several years had seen power growing in the hands of Danes. Leofric's family had served Æthelred, but Godwin had been loyal to Cnut (and was married to Cnut's sister-in-law), and Siward was probably Danish.
Dealing with his earls and increasing his own authority was crucial to his reign. We'll talk next time about some of the steps he took, some of them ruthless.
