The Czech Social Democratic Party (CSSD) was a social democratic political party in the Czech Republic that was founded in 1878 during the rule of Austria-Hungary over Bohemia. After Czechoslovakian independence in 1918, the party became one of the leading parties of the new country, and its members organized resistance movements in the German Protectorate of Bohemia and Moravia during World War II. In 1948, the party was incorporated into the Communist Party of Czechoslovakia, and the party was recreated after the 1989 Velvet Revolution. The party was always one of the two largest parties in the nation, supporting a mixed economy, a welfare state, progressive taxation, adopting the Euro, and membership in NATO (while criticizing US foreign policy).
