The major battle that took place in 1066, marking the beginning of Norman rule in England, is the Battle of Hastings. This decisive conflict occurred on October 14, when the Norman forces led by Duke William of Normandy confronted the English army commanded by King Harold II. The battle culminated in a decisive victory for William, who would become known as William the Conqueror. This victory not only resulted in the death of Harold but also led to significant political and social changes in England, including the introduction of Norman culture and governance, which transformed the English landscape for centuries to come.
