This thesis focuses on the analysis of the role of local newspapers in Croatia during the socialist period, particularly in their service to the communist regime. The media has always played a crucial role in transmitting information but also in shaping public opinion, thereby having a strong influence on social processes. The paper is divided into two main sections, theoretical and research. In the theoretical section, the history of Croatia within socialist Yugoslavia from 1945 to the 1980s is analyzed. This section covers the political, social, and economic changes that characterized Yugoslavia, with a particular focus on Croatia. Key historical events and processes such as the establishment of the communist regime and the impact of events like the Croatian Spring and Tito's death on the political and social situation in the country are described. The second part of the paper is dedicated to the development and role of the media in socialist Croatia. It covers the Soviet media model, methods of propaganda, the role of Agitprop, the Press Law, and the role of the local press in shaping public consciousness and political loyalty. The analysis examines how newspapers reflected official policy and responded to significant historical events. In the research section of the paper, a content analysis of two local weekly newspapers, Virovitički list and Vinkovački list, was conducted through three key years: 1958, 1971, and 1980. These years were chosen due to their significance in Yugoslav political history: 1958 for the VII Congress of the League of Communists of Yugoslavia, which solidified the ideological foundations of the regime; 1971 for the suppression of the Croatian Spring, which represented an attempt at liberalization and decentralization; and 1980 for the death of Josip Broz Tito. Through quantitative and qualitative analysis of newspaper articles, the study explored how these newspapers conveyed propaganda messages, reacted to political changes, and managed crises.
