War of English Succession (Harald's England)

The War of English Succession was a war over the throne of England in 1066.

Causes
The causes of this succession crisis in England were quite simply greed. William the Bastard of Normandy claimed he had been verbally promised the throne of England. Tostig Godwinson, the King's brother, contested his brother's right to inherit. Harald Hardruler of Norway made no pretenses about his invasion at all; his claim to the English throne was simply force.
