Which leaders claimed the English throne in 1066?

In 1066, several rival claimants to the English throne emerged. Among them were Harold Godwinson (recognised as king by the Witenagemot after the death of Edward the Confessor), Harald Hardrada (King of Norway who claimed to be the rightful heir of Harthacnut) and Duke William II of Normandy (vassal to the King of France, and first cousin once-removed of Edward the Confessor). Harald and William both invaded separately in 1066. Godwinson successfully repelled the invasion by Hardrada, but ultimately lost the throne of England in the Norman conquest of England.
