The work discusses the legacy of the First World War - its positive and negative sides - which played an important role in the formation of the world processes in the post-war period and still preserves its viability. The actuality of the problem is backed by the fact that the relationship of the Transcaucasian countries with the outer world is still problematic nowadays. We witness how the world's political and economic map is changing and technicalscientific progress is tangible. In the conditions of the accelerated global processes, a general political, economic and cultural area is being formed, and a new world order is being formed with its difficulties, social catastrophes or cataclysms, conflicts, divergence and integration. At this time, it is of utmost importance to analyze historical problems from the past and seek ways to resolve them in the political relations of the South Caucasus, as in their attitude towards the outside world, understanding that unity is a necessary guarantee of strengthening the statehood of each country and that the perception of the Transcaucasia the rest of the world as a unified political and economic sphere will simplify the Euro Atlantic integration. The issue is discussed from the new humanitarian perspectives, which gives us the opportunity to determine the national verticals from experience received centuries ago, around which local or regional political consciousness should be unified in order to satisfy the national interests of each country in the Transcaucasia through closer cooperation.
