The aim of this diploma thesis is to analyze ideas how to deal with the german question after the Second World War which were brought up by one of the largest postwar ecumenical organizations - Christian Peace Conference. Using this example, the author of this thesis wants to describe nature of the organization whose establishment was initiated by the cooperation between theologians and active Christians from the Eastern bloc and their Western counterparts, particularly the ones from the Federal Republic of Germany. Therefore, the thesis presents ideas of Christian Peace Conference and then compares them with the development of international relations during the Cold War and shows potential political implications of these ideas. This issue also illustrates the evolution of negotiations among European actors in the international arena after 1968. Lastly, the thesis addresses the question how could an organization like Christian Peace Conference work in the socialist state the German Democratic Republic was.
