Norwegians (Norwegian: nordmenn) are a Germanic ethnic group native to Norway. They share a common culture and speak the Norwegian language. Norwegian people and their descendants are found in migrant communities worldwide, notably in the United States, Canada, Australia, Argentina, Chile, Uruguay, Brazil, Mexico, New Zealand, United Kingdom and South Africa.
During the Viking age, Harald Fairhair unified the Norse petty kingdoms after being victorious at the Battle of Hafrsfjord in the 880s. Two centuries of Viking expansion tapered off following the decline of Norse paganism with the adoption of Christianity in the 11th century. During The Black Death, approximately 60% of the population died and in 1397 Norway entered a union with Denmark.
