What was significant about the Battle of Hastings in 1066?

The significance of the Battle of Hastings in 1066 lies in its role in establishing William the Conqueror as the ruler of England. This pivotal battle occurred between the forces of William, Duke of Normandy, and King Harold II of England. The victory for William not only marked the beginning of Norman rule in England but also initiated profound changes in English society, culture, language, and governance. After the battle, William implemented feudalism and commissioned the famous Domesday Book, which assessed land and resources in England, laying the groundwork for future administration.

The other choices pertain to events that occurred at different times in history. The Hundred Years' War began in 1337, well after the Battle of Hastings. The signing of the Magna Carta took place in 1215 and is unrelated to the events at Hastings. Lastly, the Black Death occurred during the mid-14th century, long after William's conquest. Thus, the establishment of William as the ruler of England through the victory at Hastings stands as the central and most significant outcome of that battle.
