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 First Doctor. (DW: The Time Meddler)

The Eighth Doctor and Mary Shelley once met King Harold at the Battle of Hastings. (BFA: Mary's Story) The Sixth Doctor and Peri met him after he was said to have died at that battle, when he was living under the name of Hereward the Wake. (DWA: The Real Hereward)
