December 25, 1066-William the Conqueror holds his coronation ceremony in London and becomes King of England. In 1035, Robert I, Duke of Normandy (magnanimous), died while returning from a pilgrimage to Jerusalem. Since he had no children born in wedlock, his only illegitimate child, William, was made Duke of Normandy. William was born in Falaise, the Duchy of Normandy, France. Due to the influence of Cluny's Reform, he became a devout Catholic. His personality is lively and tough. After he ascended the throne at a young age, he was threatened with assassination plots many times, but was spared thanks to the protection of his mother and King Henry I of France. Edward the Confessor, the King of England, had gone into exile in Normandy in his early years and was protected by the Normans, so he formed an alliance with him. He privately promised to transfer the right to the English throne to William after his death. But after Edward's death, Harold II succeeded to the throne of England. William insisted on his claim to the throne of England, so he sent troops to occupy England after receiving the flag of the Holy Cross from Pope Alexander II. On September 28, 1066, the Norman fleet landed in England. In the subsequent Battle of Hastings, the Normandy army defeated the Anglo-Saxon army and killed Harold II, and subsequently occupied London. On December 25, William was crowned King of England at Westminster Abbey, and the Norman Dynasty began. After William I ascended the throne, in order to suppress the rebellion of the Anglo-Saxons in the country, William I took one-fifth of the land of the United Kingdom as his territory, made his knights barons, stationed them in various places to guard them, and built many castles across the country. The Tower of London and Windsor Castle were both built during that period. William I introduced French and French living habits, some of which had a great influence on Britain. In order to grasp the population and land distribution across the country, William I sent people in 1085 and 1086 to investigate the actual situation and economic strength of aristocratic and yeoman land throughout England, and promulgated the land account book known as the "Doomsday Book". According to the results of the Doomsday Book, England has a population of approximately 1.5 million, of which more than 90% are farmers. In order to suppress the rebellion launched by his eldest son Robert II in Normandy, William I personally returned to France. He was horse and injured in Mantes in July of that year. Two months later, he died at the Convent of St. Gervais in Rouen. After his death, he was buried in the Abbayede St. Etienne in Caen, Normandy.
