Finland–Sweden relations
Finland gradually became an integrated and important part of Sweden. Finland became known as Österland, and its main urban settlement evolved in Turku. Turku was one of the biggest towns in the kingdom of Sweden, and its population included German merchants and craftsmen. Otherwise the degree of urbanization was very low in medieval Finland. During the 12th and 13th centuries, great numbers of Swedish settlers moved to the southern and north-western coasts of Finland, including the Åland Islands and the archipelago between Turku and the Åland Islands. In these regions, the Swedish language is widely spoken even today. Swedish came to be the language of the high-status people in many other parts of Finland as well.
