Jedna od osnovnih karakteristika represivne vlasti u međuratnoj Jugoslaviji svakako je bilo i suzbijanje širenja komunističkih odnosno boljševičkih ideja u radničkom pokretu nakon Prvog svjetskog rata. Ovo je uvelike bilo uvjetovano povratkom ruskih zarobljenika, tj. vojnika Austro-Ugarske Monarhije koji su tijekom zarobljeništva prihvatili ideju boljševizma te koju su potom pokušali prenijeti na teritorij novouspostavljene Kraljevine. Ovi su se „oktobarci“, kako ih je kasnija historiografija nazvala, vraćali i na slavonsko područje, prvenstveno u gradove poput Osijeka i Vukovara. U kontekstu navedenoga cilj je rada, na temelju arhivske građe, kao i onodobnog tiska, analizirati načine na koje su vlasti vršile ovo suzbijanje, pri čemu se slavonsko područje promatra u širem društveno-političkom kontekstu, kako bi se dobila potpunija analiza djelovanja represivnog sustava, ali i načina transferiranja ideja na ovo područje. Kreiranje antiboljševičke politike interpretirano je okviru komparativne metode te teorijskog modela nizozemskog teoretičara T. A. van Dijka. One of the basic characteristics of the repressive government of Yugoslavia between the two World Wars certainly was also the inhibition of the spreading of communist, i.e. Bolshevik ideas in the labour movement after World War I, which was to a great extent ascribable to the return of Russian prisoners, that is to say soldiers of the Austro-Hungarian Monarchy who had during their imprisonment accepted the idea of Bolshevism and accordingly tried to transfer it to the territory of the newly established Kingdom. These “adherents of the October Revolution”, as they were later named in historiography, returned to the Slavonian area, primarily to the towns Osijek and Vukovar. The objective of this paper in this context is to analyse on the basis of archival materials and then newspapers how the government imposed the restraint, the Slavonian area being viewed in a broader social-political context in order to provide a more complete analysis of the activities of the repressive system but also of how ideas were transferred in this area. The creation of an anti-Bolshevik policy has been interpreted in the scope of the comparative method and the theoretical model of the Dutch theorist T. A. van Dijk.
