Battle of Hastings
On 5 January 1066, Edward the king died, but Harold did not respect his oath to William. The next day, the day of the funeral, Harold was crowned king of England. The story was that on his deathbed the king had changed his mind and promised Harold the throne. Harold was not royalty himself and had no legal claim on the throne. For weeks William must have known Edward was dying, but the news of the king's death and Harold's taking the throne must have been a surprise.
