Abstract: As a consequence of the outbreak of the Soviet-Yugoslav conflict, Cominform emigrant communities were established in the Soviet Union and in Eastern Europe, including Hungary. The emigrants took an active part in the ongoing anti-Titoist propaganda campaign. This paper focuses on Lazar Brankov, the first leader of ibeovci emigrants in Hungary, his political activities and his role in organizing the emigrants’ community in Hungary. Special emphasis is placed on their propaganda activities and the relationship between the emigrants and the Hungarian authorities. The article is based on archival research that was carried out at Hungarian archives.

Key words: Soviet-Yugoslav conflict, Yugoslav-Hungarian relationships, ibeovci emigrants, Cominformist emigrants, Lazar Brankov
