England
This was first done by Æthelstan in 927 and Eadred in 953. A wave of Scandinavian attacks from the late 10th century ended with the conquest of this united kingdom by Sweyn Forkbeard in 1013 and again by his son Cnut in 1016, turning it into the centre of a short-lived North Sea Empire that included Denmark and Norway. However, the native royal dynasty was restored with the accession of Edward the Confessor in 1042. When King Edward died, Harold Godwinson (the Earl of Wessex) became king. William the Conqueror, Duke of Normandy (today part of northern France), said that Harold had promised to make William the king. He invaded England and fought King Harold at the Battle of Hastings in 1066. William won, and became king of England.
