Founded in 1939 as a split from the Self-Government Party and by former members of the Business Party (Vinnuflokkurin), the party has traditionally supported greater autonomy for the Faroe Islands. Party leader Hákun Djurhuus served as Prime Minister from 1963 to 1967, as did Jógvan Sundstein from 1989 to 1991. In 1998, it adopted a policy of full independence from Denmark as part of a coalition deal in which leader Anfinn Kallsberg became PM. From 2004 until 2011, except for a short period in 2008, the party has been in coalition with the Union Party and Social Democratic Party, who want to maintain the political status quo. Since November 2011 the party has been in a coalition with the Union Party (Sambandsflokkurin), the Centre Party (Miðflokkurin) and until September 2013 also with the Self-Government Party (Sjálvstýrisflokkurin), who left the coalition after their minister had been sacked.
