Finnish People's Democratic League (Finnish: Suomen Kansan Demokraattinen Liitto, SKDL; Swedish: Demokratiska Förbundet för Finlands Folk, DFFF) was a Finnish political organisation with the aim of uniting those left of the Finnish Social Democratic Party. It was founded in 1944 as the anti-communist laws in Finland were repealed due to the demands of the Soviet Union, and lasted until 1990, when it merged into the newly formed Left Alliance. At its time, SKDL was one of the largest leftist parties in capitalist Europe, with its main member party, the Communist Party of Finland, being one of the largest communist parties west of the Iron Curtain. The SKDL enjoyed its greatest electoral success in the 1958 parliamentary election, when it gained a support of approximately 23 per cent and a representation of 50 MPs of 200 total, making it the largest party in the Eduskunta.
