 Since 2007, the SSk is affiliated to the Democratic Party (PD).The relation between the two parties is regulated by an "agreement of federation", which guarantees the full autonomy of the SSk.The SSk was founded in 1962 with the merger of several Slovene anti-communist political organizations that had functioned since 1945 in the Italian part of the Julian March (Venezia Giulia), that is in the provinces Gorizia and Trieste (until 1954 Zone A of the Free Territory of Trieste).
