This Master's Thesis researches protests in Yugoslavia that happened as a reaction to the news of the death of Congolese Prime Minister Patrice Emery Lumumba. There are three main premises that this work touches upon. The first premise is that interest in the Congo Crisis in Yugoslav society stems from diligent work of Yugoslav journalists. Their work showed excellent understanding of the whole situation, as does their analysis, which in far greater measure than any work of League of Communists of Yugoslavia (LCY), contributed to the success and wide appeal of demonstrations that happened in February of 1961. The second premise is that the Congo Crisis was an important factor in the disillusionment of the Yugoslav government in regards to building their foreign affairs based on the premises that Organisation of United Nations can effectively stop meddling of third parties in sovereign nations. The inability of the UN to peacefully resolve the Congo crisis in favour of their man Patrice Lumumba brought about strong criticism from Yugoslavia towards the UN, Security Council and general secretary Dag Hammarskjöld. The third and main premise is that LCY and its Croatian counterpart League of Communists of Croatia didn’t have the monopoly on opinion making regarding foreign and world affairs. A combination of genuine interest from Yugoslav citizens and media coverage brought about the demonstrations and humanitarian actions which tried to help Congolese people. The realisation that people’s interests lie in foreign affairs and the formation of the Non-aligned movement brought on the realisation that the party has to take hold of that part of Yugoslav societies’ interests. Demonstrations could not have happened without implicit permission from state and party; however, they probably wouldn’t have been as successful as they were if there wasn’t genuine solidarity between the Yugoslavs and their Congolese counterparts.
