After Cnut's death in 1035, the English throne fell to Harold Harefoot, his son by his first wife, while Harthacnut, his son by Emma, became king in Denmark. England remained unstable. Alfred returned to England in 1036 to visit his mother and perhaps to challenge Harold as king. One story implicates Earl Godwin of Wessex in Alfred's subsequent death, but others blame Harold. Emma went into exile in Flanders until Harthacnut became king following Harold's death in 1040, and his half-brother Edward followed Harthacnut to England; Edward was proclaimed king after Harthacnut's death in June 1042.
