Harold Godwinson

Harold Godwinson was king of England for most of 1066. Although he defeated a Viking invasion, he was himself later defeated in the Battle of Hastings by William the Conqueror, who became the new king of England. The Monk planned to change history by using advanced technology to aid King Harold, thus ensuring that his army would be better able to face William's army. This plan was defeated by the Doctor.
