Languages of Sweden
Swedish is the official language of Sweden and is spoken by the vast majority of the 10 million inhabitants of the country. It is a North Germanic language and quite similar to its sister Scandinavian languages, Danish and Norwegian, with which it maintains partial mutual intelligibility and forming a dialect continuum. Five "national minority languages" are also recognized by Swedish law: Finnish, Yiddish, Meänkieli, Romani and Sami.
Mandatory Swedish
The status of Swedish as a national language in Finland is defined by the Finnish constitution. There was migration of Swedish-speaking peasants to some Finnish coastal areas during the Middle Ages. During this period, when Finland was ruled by Sweden, Swedish language became part of the culture in the coastal areas. Swedish was also the language of the ruling class. The Finnish language was forbidden an official status alongside Swedish until the period of Russian rule (1809–1917), in 1860. The autonomous Åland Islands (pop. 26,000, 95% Swedish, 5% Finnish) has only one official language, Swedish, and the speaking of Finnish between employees is forbidden in some public services.
