Autonomy Day (Åland)

Åland's Autonomy Day, or Åland's Self-Government Day, is celebrated annually on 9 June to commemorate the first meeting of the Åland County Council on that date in 1922. Åland's self-government from Finland was established in 1921 by a decision of the League of Nations, following the Åland Movement's demand for reunification with Sweden.

Åland is an autonomous and demilitarised region of Finland. Receiving its autonomy by a 1920 decision of the League of Nations, it is the smallest region of Finland by both area and population (30,654), constituting 0.51% of Finland's land area and 0.54% of its population. Its only official language is Swedish and the capital city is Mariehamn.
