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
Latin as the language of the Catholic Church was introduced in Sweden with the Christianisation, around AD 1000. As in most of Europe, Latin remained the lingua franca and scholarly language of the educated communities for centuries in Sweden. For instance, Carl Linnaeus' most famous work Systema Naturae, published in 1735, was written in Latin.
