William the Conqueror is considered the first Norman King of England. He reigned from 1066 until 1087. Some people considered him as greedy and brutal. Many people nowadays confuse him of being either a hero or a villain.
Under his administration, he promoted the European culture by building many infrastructures such as castles and keeps. One of which is the "White Tower" in London which is the most famous castle keep in the world. It was built to prevent foreign invaders into the nation. William loves hunting, thus he introduced forest laws. The law regulated the number of animals in the nation.
