The Battle of Hastings was fought on Oct. 14, 1066, between the Anglo-Saxon army of King Harold II of England and the Norman-French army of Duke William II of Normandy. The battle, which is depicted on the famous Bayeaux Tapestry, was one of the bloodiest battles in English history.
Duke William forced the battle after landing his army in southwestern England in what is known as the Norman Invasion of England. The reason for his invasion was that William believed he was the rightful heir to the English throne and that Harold had earlier agreed to support his claim. However, after the death of King Edward the Confessor, Harold was quickly named king, which angered Duke William.
The result of the battle saw King Harold killed, leading Duke William to eventually be named the new king. Due to the defeat of the English by the Norman French, King William became known as William the Conqueror.
Duke William was not the only nobleman to protest against Harold being named king. In fact, just a few weeks before, King Harold had defeated the army of King Harald Hardrada of Norway, who also believed that he should be the rightful king of England.
