Communist Party of Slovenia

The League of Communists of Slovenia (Slovene: Zveza komunistov Slovenije, ZKS; Serbo-Croatian: Savez komunista Slovenije) was the Slovenian branch of the League of Communists of Yugoslavia, the sole legal party of Yugoslavia from 1945 to 1990. It was established in April 1937 as the Communist Party of Slovenia and was the first autonomous sub-national branch of the federal party. Its initial autonomy was further amplified with the Yugoslav constitution of 1974, which devolved greater power to the various republic level branches.
