In political theory has long been noticed the importance of public opinion and public attitudes in political issues. Communication framework of the policy represents one of the key aspects of the political system and political action, the public is a factor that affects, to a greater or lesser extent, the foreign policy decision makers. In the paper we discuss public attitudes towards Bulgaria in the period of intensifying of political crisis in the Yugoslav-Bulgarian political relations, stereotypes and 'images' of Bulgarians in the Serbian public opinion, wanting to show how the political conflict reflected on the linguistic, symbolic and collective-psychological level. Methodologically, the research is focused on content analysis of print media, namely, the most important daily newspapers and periodicals in the 1920s, especially Belgrade's daily newspapers 'Politika', 'Vreme' and 'Pravda', which doubtless, had the greatest influence on the creation of public opinion. Chronologically, the research period is clearly limited with key political events and the ongoing crisis in the relations that they caused. This paper represents the original scientific contribution to the understanding of political attitudes of the Yugoslav postwar public, and to the deepened understanding of the Yugoslav-Bulgarian relations during the indicated period.
