French conquest of England The Norman(from Normandy in France) conquest of England began on 28 September 1066 with the invasion of England by William the Conqueror, Duke of Normandy and his victory at the Battle of Hastings on 14 October 1066 over King Harold II of England. Harold's army was badly depleted in the English victory at the Battle of Stamford Bridge in Northern England on 25 September 1066 over the army of King Harald III of Norway. By early 1071, William had secured control of most of England, although rebellions and resistance continued to approximately 1088. The Norman conquest was a pivotal event in English history. It largely removed the native ruling class, replacing it with a foreign, French-speaking monarchy, aristocracy, and clerical hierarchy. This, in turn, brought about a transformation of the English language and the culture of England in a new era often referred to as Norman England. By bringing England under the control of rulers originating in France, the Norman conquest linked the country more closely with continental Europe, lessened Scandinavian influence, and also set the stage for a rivalry with France that would continue intermittently for many centuries. It also had important consequences for the rest of the British Isles, paving the way for further Norman conquests in Wales and Ireland, and the extensive penetration of the aristocracy of Scotland by Norman and other French-speaking families, with the accompanying spread of continental institutions and cultural influences.
