Swedish Social Democratic Party
During most of the post-war era, Sweden was governed by the Swedish Social Democratic Party largely in cooperation with trade unions and industry. In Sweden, the Swedish Social Democratic Party held power from 1936 to 1976, 1982 to 1991, 1994 to 2006 and 2014 through 2023, most recently in a minority coalition. Tage Erlander was the first leader of the Swedish Social Democratic Party (SSDP). He led the government from 1946 to 1969, the longest uninterrupted parliamentary government. These governments substantially expanded the welfare state. Swedish Prime Minister Olof Palme identified as a "democratic socialist" and was described as a "revolutionary reformist".
