The Independent Democratic Party (Serbo-Croatian: Samostalna demokratska stranka, Самостална демократска странка; Slovene: Samostojna demokratska stranka, SDS) was a social liberal political party in the Kingdom of Serbs, Croats and Slovenes, and later the Kingdom of Yugoslavia. It was established by Svetozar Pribićević as a breakaway faction of the Democratic Party in 1924. It was formed by three different groups: by far the largest group were the Serbs from the areas of the former Austro-Hungarian Empire, that is Croatian, Bosnian and Vojvodina Serbs, with the prevalence of the first. The second most influential group were Slovene centralist liberals. The third group was composed by Croat liberals, mostly from Dalmatia and Zagreb.
