1. The Norman Invasion of England (1066)
In 1066, William, Duke of Normandy, launched a decisive invasion of England, culminating in the Battle of Hastings on October 14. This victory over King Harold II led to the establishment of Norman rule, profoundly transforming English society. The conquest introduced feudalism, redistributed land to Norman lords, and significantly influenced the English language, incorporating numerous Norman words. The legacy of this invasion continues to shape British culture and governance (britannica.com).
