Yugoslavia was the first country behind the Iron Curtain where the communists assumed total power. By 1945, they had already mostly taken over the mechanisms of power, the police apparatus and the military; furthermore they were supervising the majority of the media in preparation for the 11 November 1945 elections, where the total domination of communists in the state was confirmed. The present paper presents the attitude of the leading communists towards the political parties and leaders of the opposition over the course of six months after the end of World War II. The influence of the opposition was different in the various parts of Yugoslavia. It was the strongest in Serbia and in Croatia, while it barely had any influence in Slovenia. In their public appearances, the leading Communists derided and despised the opposition, associating it with those who had collaborated with the occupation forces during the war. They had already started avoiding the term “opposition” before the elections, while afterwards this word almost vanished from their vocabulary: instead, they would refer to “reactionary forces” or “national traitors”.
