Official minority languages of Sweden
Finnish has been spoken in Sweden ever since the (then provincial) borders were drawn in the 13th century. Sweden has always had a significant migration to and from Finland. As the two languages belong to different language families it is easy to distinguish them, unlike the neighbouring languages Norwegian and Danish. The number of Finnish speakers in Sweden today has been estimated to over 460,000. Even though many current Swedes are of full or mixed Finnish descent, Swedish is the main language in practice for many bilinguals.
Languages of Sweden
In medieval Sweden, the Low German language had a very important role as a commercial language and the lingua franca of the Hanseatic league. As such, the Low German language influenced Swedish and other languages in the region considerably. In medieval Stockholm, half of the population were Low German speakers. Low German was also the language spoken in the 17th-century Swedish territories in northern Germany i.e. Swedish Pomerania, Bremen-Verden, Wismar and Wildeshausen (as well as the rest of northern Germany) and by the German minority in Estonia and Swedish Livonia. Livonia was also inhabited by Latvians, Estonians and Livonians.
