Dan Snow takes on one of the most famous dates in British history when, 950 years ago, William of Normandy, soon to be Conquerer, defeated Harold, King of England, at the Battle of Hastings. But 1066 is more than just one battle on one day. It is the dramatic story of a single year when the ancient world of the Anglo-Saxons is swept aside and the dominance of the Vikings is brought to a shuddering halt. It's the year when the power balance of Europe is upturned and Britain's future determined. Dan reconstructs the events of 1066 as they unfolded, and brings them vividly to life in action-packed drama as our three warlords Harold, William of Normandy, and the Viking Harald Hardrada fight for supremacy.
