Why where and how did William the Conqueror invade England?

William the Conqueror invaded England in 1066 because he believed he had a legitimate claim to the English throne. After the death of Edward the Confessor, who did not have any children, there were several contenders for the throne, including Harold Godwinson, who was crowned King of England. William argued that Edward had promised him the throne and that Harold had broken his oath to support William's claim.

William's invasion was also motivated by a desire to expand his power and influence in Europe. By conquering England, he would become one of the most powerful rulers in Europe and would also gain control of England's valuable resources.

William's invasion was a well-organized and successful military campaign. He assembled a large army and navy and crossed the English Channel from Normandy in September 1066. He landed in Sussex and defeated Harold's forces at the Battle of Hastings on October 14, 1066. Harold was killed in the battle and William was crowned King of England on Christmas Day 1066.

William's invasion had a profound impact on English history. He introduced a new system of government and administration and brought many Norman customs and traditions to England. He also ordered a survey of all the land in England, known as the Domesday Book, which provided a detailed record of the country's resources and population. William the Conqueror's invasion and reign marked the beginning of a new era in English history.
