In this paper the main task is to describe the structuring of the Cold War during one of his first stages. The case of Yugoslavia and Cominform Bureau resolution in 1948. will be explained. The paper describes initial situation in Yugoslavia, where its political elite without a doubt sided with the Eastern camp. Paper will describe the mania that ruled in Yugoslavia towards Stalin, ideological leader of Soviet Union, as wheel as idolatry during and short after the end of World War 2. One of the main phenomena which will be described in paper, is the fact that one state turned its interest and political course in a very short time, to an almost unexplainable degree. The Soviet Union was considered a fellow state, and their leader Stalin was considered a leader of all socialist nations. Soviet Union saw Yugoslavia as the brightest example of socialism implementation, and a new order in a battle against western imperialism. That idyllic relationship was ruined in a few years that followed. Yugoslavia went from being a „golden goose“ to a „black sheep“ in the eyes of Soviet Union, and the Soviets became a dark force with the goal to eliminate Yugoslavian freedom which had been won in blood. This paper describes the chronology of Tito-Stalin conflict through institute of comrade critics, opened letters, warning speeches at meetings and congresses, and finally with Cominform Bureau resolution which convicted Yugoslav leadership of having demolished the foundations of socialism, and called upon ousting Yugoslav leaders. Following that, it is described how Yugoslavia denied the resolution, which led to hysteria over a possible Soviet invasion, and a conflict with internal enemies of new founded Tito’s policy. In its final and part the paper describes the peak of Yugoslav-Soviet crisis, after which came to normalization of relations, elimination of the threat from possible invasion and conflict, and it is described in which way the Cold War was structured in Europe, after Yugoslavia left the influential sphere of Soviet Union.
