Wiliam hated his eldest brother, Robert.
When they were children, William and his younger brother Henry emptied a chamber-pot over Robert’s head. Their father had to break up the ensuing fight. Their mutual dislike was only halted when Robert went to fight the First Crusade leaving William to manage the duchy of Normandy.
William never married and had no known heirs besides his siblings. When he died his brother Henry acceded to the throne.
William was known as Rufus. This is latin for ‘red’ and refers to his colourful hair and complexion. Some say it also refers to his temper.
William was not at all religious
This was unusual at the time. Perhaps even more so since his father William the Conqueror was very pious. William II was accussed of being crass and blasphemous, by churchmen at least.
It may be that William’s younger brother Henry was behind his death. The actual arrow was fired by Sir Walter Tirel. However, Henry was quick to ride off and claim William’s crown while he lay bleeding to death in the New Forest. It was left to local villagers to cart his body to Winchester Cathedral.
