William the Conqueror

William the Conqueror, (TV: The Time Meddler) also known as William of Normandy, (PROSE: A History of Humankind) defeated King Harold Godwinson in the Battle of Hastings in 1066. The First Monk planned to change history by ensuring Harold's army would be better able to face William's army, but this plan was defeated when a group of Saxons ran the Monk out of his monastery. (TV: The Time Meddler) Following the failure of this plan, the Monk witnessed William's victory at Hastings and his coronation on 25 December 1066. (PROSE: The Time Meddler)

The king began the construction of what he named the Tower of London in 1078, and many of the monarchs who succeeded him extended and added to the tower over the centuries that followed. (PROSE: )
