Serbian Social Democratic Party (Kingdom of Serbia)

Serbian Social Democratic Party (Serbian Latin: Srpska socijaldemokratska partija) was a political party that was formed in 1903 in the Kingdom of Serbia. Some of its leaders included Dimitrije Tucović, Dragiša Lapčević, and Dušan A. Popović. It ceased to exist after World War I with the creation of the Kingdom of Serbs, Croats and Slovenes, when in 1919 the social democrats joined the new Social Workers' Party of Yugoslavia (Socijalistička radnička partija Jugoslavije (komunista)), the predecessor of the Communist Party of Yugoslavia.
