The Battle of Hastings, fought on October 14, 1066, was a significant event in English history as it marked the Norman Conquest of England. The battle pitted the forces of Duke William of Normandy against King Harold II. William's victory led to the establishment of Norman rule in England, dramatically altering the language, culture, and governance of the country. The defeat of Harold, who was killed during the battle, resulted in the end of Anglo-Saxon control and the introduction of feudalism. Consequently, the Battle of Hastings laid the groundwork for a new social and political order, reshaping the course of English history.
