THERE INVASION

The Normans that invaded were under the rule of William the Conquer and Hardrada. 

 King Edward of England (called "The Confessor" because of his construction of Westminster Abbey) died on January 5, 1066, after a reign of 23 years. Leaving no heirs, Edward's passing ignited a three-way rivalry for the crown that culminated in the Battle of Hastings and the destruction of the Anglo-Saxon rule of England.

Across the English Channel, William, Duke of Normandy, also laid claim to the English throne. William justified his claim through his blood relationship with Edward (they were distant cousins)
