the daughter of Baldwin IV, Count of Flanders. Edward was ailing, and he died on 5 January 1066. It is unclear what exactly happened at Edward's deathbed. One story, deriving from the Vita Ædwardi, a biography of Edward, claims that he was attended by his wife Edith, Harold, Archbishop Stigand, and Robert FitzWimarc, and that the king named Harold as his successor. The Norman sources do not dispute the fact that Harold was named as the next king, but they declare that Harold's oath and Edward's earlier promise of the throne could not be changed on Edward's deathbed. Later English sources stated that Harold had been elected as king by the clergy and magnates of England. Invasion of England Harold's preparations Harold was crowned on 6 January 1066 in Edward's new Norman-style Westminster Abbey, although some controversy surrounds who performed the ceremony. English sources claim that Ealdred, the Archbishop of York, performed the ceremony, while Norman sources state that the coronation was performed by Stigand, who was considered a non-canonical archbishop by the papacy. Harold's claim to the throne was not entirely secure, as there were other claimants, perhaps including his exiled brother Tostig. King Harald Hardrada of Norway also had a claim to the throne as the uncle and heir of King Magnus I, who had made a pact with Harthacnut in about 1040 that if either Magnus or Harthacnut died without heirs, the other would succeed. The last claimant was William of Normandy, against whose anticipated invasion King Harold Godwinson made most of his preparations. Harold's brother Tostig made probing attacks along the southern coast of England in May 1066, landing at the Isle of Wight using a fleet supplied by Baldwin of Flanders. Tostig appears to have received little local support, and further raids into Lincolnshire and near the River Humber met with no more success, so he retreated to Scotland, where he remained for a time. According to the Norman writer William of Jumièges, William had meanwhile sent an embassy to King Harold Godwinson to remind Harold of his oath to support William's claim, although whether this embassy actually occurred is unclear. Harold assembled an army and a fleet to repel William's anticipated invasion force, deploying troops and ships along the English Channel for most of the summer.
