The Norman Conquest was the conquest of the Kingdom of England by William the Conqueror (Duke of Normandy), in 1066 at the Battle of Hastings and the
subsequent Norman control of England.
Hastings - Bayeux
It is an important watershed in English history for a number of reasons. It tied England more closely with Continental
Europe and away from Scandinavian influence, created one of the most powerful
monarchies in Europe, created the most sophisticated governmental system in
Europe, changed the English language and culture, and set the stage for a long
future of English-French conflict. It remains the last successful military
invasion of England.
