From the beginning of the 1980's, the Historical Archives Ljubljana have also taken care of the
archive materials belonging to regional organisations of the Association of Communists of Slovenia.
The material, expert work and users services are concentrated in Ljubljana for the whole area,
covered by the archive. The material in five fonds on the level of municipality and county reflects its
usability for research into local history. The organisation and the work of the party in the Idrijsko
and Cerkljansko area from 1945 to 1986 are presented. At that time, the Association of Communists
of Slovenia was the leading social-political organisation, i.e. the only political party in the country.
