From the period of the Kingdom of Yugoslavia 148 fonds have been preserved.

The number of record groups and the quantity of materials from this period would undoubtedly be larger had it not been for the large-scale devastation of this part of our cultural heritage too during World War II. Apart from that, selected archival records were systematically carted away by the occupying power.
Despite the incompleteness of archival material from the period of the Kingdom of Yugoslavia, record groups of the central bodies of authority and state administration in the spheres of internal and foreign policy, finance, economy, health, education, culture, welfare, justice, banking etc. constitute valuable and crucial sources for studying the history of the Kingdom of Yugoslavia.

In classifying and processing record groups, those from from the period of the Kingdom of Yugoslavia have been accorded priority in view of their having become accessible for use, and most of them have been processed and equipped with finding aids.

Basic information about archival material from the period of the Kingdom of Yugoslavia can be found in the Guide Through the Holding Funds of the Kingdom of Yugoslavia, published in 2000.
