The subject of our research is the summer hut association that began functioning at a small island off the coast of Helsinki after World War II. Residents of the island were members of the Communist Party of Finland (Suomen Kommunistinen Puolue, SKP) or of the Finnish People's Democratic League (Suomen Kansandemokraattinen Liitto, SKDL). This organisation was founded in 1944 to unite those politically left of the Finnish Social Democratic Party (SDP), that is, mainly communists and socialists. We attempt to investigate how the summer hut community emerged and was organised at Vasikkasaari Island. What sort of community formed on the island, and how did its relationship to coastal nature develop at the time? What sort of emotions and affects did the natural world of the seashore elicit in members of the community? We have found no studies on the history of summer huts in Finland or abroad. The subject of our research is, then, a new theme on an international scale.
