Viking and Middle Ages
Danish Vikings were most active in what areas?
Denmark
From the 8th to the 10th century, the Danes, as well as Norwegians and Swedes, were known as Vikings. They colonised, raided, and traded in all parts of Europe. Viking explorers first discovered Iceland by accident in the 9th century, on the way towards the Faroe Islands and eventually came across "Vinland" (Land of wine), also known today as Newfoundland, a province in Canada. The Danish Vikings were most active in the British Isles and Western Europe. They conquered and settled parts of England (known as the Danelaw) under King Sweyn Forkbeard in 1013, Ireland, and France where they founded Normandy. More Anglo-Saxon pence of this period have been found in Denmark than in England. As attested by the Jelling stones, the Danes were united and Christianised about 965 by Harald Bluetooth. It is believed that Denmark became Christian for political reasons so as not to get invaded by the rising Christian power in Europe, Germania, which was an important trading area for the Danes. In that case Harald built six fortresses around Denmark called Trelleborg and built a further Danevirke. In the early 11th century, Canute the Great won and united Denmark, England, and Norway for almost 30 years. Throughout the High and Late Middle Ages, Denmark also included Skåneland (Skåne, Halland, and Blekinge) and Danish kings ruled Danish Estonia, as well as the duchies of Schleswig and Holstein. Most of the latter two now form the state of Schleswig-Holstein in northern Germany. In 1397, Denmark entered into a personal union with Norway and Sweden, united under Queen Margaret I. The three countries were to be treated as equals in the union. However, even from the start Margaret may not have been so idealistic—treating Denmark as the clear "senior" partner of the union. Thus, much of the next 125 years of Scandinavian history revolves around this union, with Sweden breaking off and being re-conquered repeatedly. The issue was for practical purposes resolved on 17 June 1523, as Swedish King Gustav Vasa conquered the city of Stockholm. The Protestant Reformation came to Scandinavia in the 1530s, and following the Count's Feud civil war, Denmark converted to Lutheranism in 1536. Later that year, Denmark entered into a union with Norway.
