Social Democrats (Denmark)

The Social Democrats (Danish: Socialdemokratiet, pronounced [soˈɕɛˀlte̝moˌkʰʁɑˀtɪət]) is a social democratic political party in Denmark. A member of the Party of European Socialists (PES), the Social Democrats have 50 out of 179 members of the Danish parliament (following the latest Danish general election held in 2022), Folketing, and three out of fourteen MEPs elected from Denmark.

Founded by Louis Pio in 1871, the party first entered the Folketing in the 1884 Danish Folketing election. By the early 20th century, it had become the party with the largest representation in the Folketing, a distinction it would hold for 77 years. It first formed a government after the 1924 Danish Folketing election under Thorvald Stauning, the longest-serving Danish Prime Minister of the 20th century. During Stauning's government which lasted until the 1926 Danish Folketing election, the Social Democrats exerted a profound influence on Danish society, laying the foundation of the Danish welfare state. From 2002 to 2016, the party used the name Socialdemokraterne in some contexts. The party was a member of the Labour and Socialist International from 1923 to 1940. A member of the Socialist International until 2017, the party withdrew to join the Progressive Alliance, founded in 2013.

The party was the major coalition partner in government from the 2011 Danish general election until the 2015 Danish general election, with then-party leader Helle Thorning-Schmidt as Prime Minister. After losing power in the 2015 election, Thorning-Schmidt was succeeded as party leader on 28 June 2015 by the former Vice Leader Mette Frederiksen, who shifted the party back to the political left on economics, while criticising mass immigration. Frederiksen led the party to win the 2019 and 2022 Danish general election, forming a single-party minority government from 2019–22 and a majority grand-coalition government with the centre-right Venstre and the centrist Moderates since 2022.
