The Battle of Stamford Bridge was a major turning point in the Viking Invasion of England. It was fought between the Anglo-Saxon King Harold Godwinson and Norwegian Viking King Harald Hardrada. In the battle, the defeat of the Anglo-Saxon forces led to Harald Hardrada being crowned King of Norway and England.
Crown of England
In January of 1066, King Edward the Confessor of England died, which led to a power struggle between many northern European powers. Harold Godwinson, who had been crowned king as the rightful successor, was challenged by William of Normandy and Harald Hardrada of Norway.
Harald, King of Norway, amassed over 300 vessels and 15,000 men to attack England. He was joined by Harold's younger brother, Tostig Godwinson, who had an additional contingency of Scottish and Dutch warriors.
Details in development.
Harald, King of Norway, managed to score a blow to the Anglo-Saxon Kingdom, and both Harold and Tostig Godwinson die in the fighting. Harald can then take the remainder of northern England with relative ease, and becomes ready to fight William of Normandy, who is growing in power to his south.
Harald ends up the King of Norway and England.
