William of Normandy is better known to us today as William the Conqueror. This is because he was the Norman nobleman who led an invasion of England. The invasion was successful and William became the first Norman king of England.
The Normans were the descendants of Vikings who had settled in Northern France. William’s father was duke of Normandy, but William himself was illegitimate. He was known in his time as William the Bastard. Even so, William’s father named him his heir and William became duke when his father died. His military and political skills gained him more and more power. Eventually, in 1066, he invaded and conquered England.
