The Norman Empire refers to the territories ruled by the Normans, a group of people descended from Vikings who settled in what is now Normandy, France. In the 11th century, they expanded their influence across Europe, notably through the conquest of England in 1066, led by William the Conqueror. This event significantly shaped English history and culture. The Normans were known for their military prowess, architectural innovations, and administrative skills. They built impressive structures, such as castles and cathedrals, and introduced feudalism in the regions they controlled. Their legacy can still be seen today in various aspects of European culture and governance.
