When were the Normans discovered?

The Normans were not "discovered" in the traditional sense, as they were a group that emerged in the 10th century. They were originally Norse settlers, primarily from Scandinavia, who settled in what is now northern France, particularly in the region known as Normandy. Their presence became prominent after the establishment of the Duchy of Normandy in 911, following the Treaty of Saint-Clair-sur-Epte. The Normans later gained notoriety for their conquests, including the pivotal Norman Conquest of England in 1066.
