The most important year in British history. After the death of Edward the confessor, three aristocracy of europe claimed the throne. Harold II had already taken the throne. His first opposition came from Viking warlord
Harald Hadraada. The viking army was defeated without much hassle. William, duke of Normandy then came from France to the
south coast. Harold II ploughed his army onto William's without rest. They made good time, but were exhausted. William used
simple but effective maneuveres to kill off many thousands of English. Harold died during the battle, and William became William the conquerer. All monarchs since have been of his lineage. Also, there have been over 50 attempts to invade britain since that point, all of which have failed.
