In 2009, the Riksdag passed the Language Law recognizing Swedish as the "main" and "common" language of society as well as being the official language in "international contexts", the five national minority languages, and Swedish sign language .
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.
