The control of the state security services from the middle of 1966 untill the beginning of 1975

The Brioni plenum took place in mid 1966. It was carefully planned and prepared beforehand. The decisions made there will have a crucial importance and far-reaching consequences for the fate of Yugoslavia at the time. This event sped up the process of the decentralization of the power of the state. Furthermore, it brought a completely new organization based on this new concept, as well as a new role and jurisdiction of the newly formed State Security Service. Based on the Law on Federal councils, the Federal Council for the Protection of the Constitutional Order was established from July 1966 until the beginning of 1975. Based on original and so far unpublished sources, this paper attempts to show and explain how these governing bodies and organs functioned. The main task of these governing bodies and organs was to follow, control, guide and coordinate the activities of the extremely complex security intelligence system of SFRY.
