During the 19th and early 20th centuries, the Eastern question and the search for ways to solve it occupied a central place in the politics of both Russia and European states. The solution of this issue was closely linked with the process of formation of the young Balkan countries. The Formation of new statehood in Serbia typologically coincided with a change in the system of European international relations of the 19thand early 20th centuries, played an important role in the events of the Eastern question, while claiming to be the Yugoslav “Piemont.” However, by the beginning of the 20th century, it was war that had become, both for Serbia and for the other countries of the region, not only a means of gaining state sovereignty, but also the main way to resolve its own interstate contradictions, which happened against the background of an external factor – the impact of the Great Powers on the political processes in the Balkans. These factors led to the natural militarization of the everyday life of Serbian society. The presence in the everyday consciousness of the image of a hostile “other” became one of the main ways to consolidate the country, when attitudes towards war, pushing the values of peaceful life to the background, created a special basic consensus in the state development of Serbia at the beginning of the 20th century, and the anthropological role of the military factor essentially influenced the underlying processes that took place in the country at the beginning of the 20th century. In the conditions of a new stage of destruction of the Balkans along ethno-political lines, the factor of the militarization of everyday life again becomes an important element of the historical policy of the Balkan countries and the construction of a “new past.” In this regard, the understanding of many problems and possible scenarios for the development of the current Balkan reality is linked to this phenomenon. Thus, the study of the impact of special “extra-constitutional” institutions on the political life of Serbia at the beginning of the 20th century is important for a wide range of researchers, including for a systematic analysis of the crisis in the territory of the former Socialist Federal Republic of Yugoslavia.
