The Battle of Hastings took place on 14 October 1066, and it was one of the most decisive battles in English history. It was fought between the Norman-French army led by William, Duke of Normandy (later known as William the Conqueror), and the English army led by King Harold II.
William claimed the English throne based on an alleged promise by the previous king, Edward the Confessor, and an oath supposedly sworn by Harold himself. When Harold was crowned king after Edward's death in January 1066, William invaded England. The two armies met near Hastings in southern England, and after a hard-fought battle lasting most of the day, Harold was killed (traditionally depicted as being struck in the eye by an arrow) and the English army was defeated.
William's victory at Hastings led to the Norman Conquest of England, fundamentally transforming English society, language, law, architecture, and governance. The famous Bayeux Tapestry depicts the events leading up to and including the battle.
The year 1215 is associated with the signing of the Magna Carta. The year 1588 saw the defeat of the Spanish Armada. The year 1492 is when Christopher Columbus reached the Americas. None of these events relate to the Battle of Hastings.
The correct answer is 1066, the year of the Battle of Hastings and the Norman Conquest of England.
