On the History of Ukrainian Military Diplomacy in Poland in 1920 (according to the Documents of Сentralne Archiwum Wojskowe)

The aim of the article lies in incorporating unpublished archival documents preserved in the Central Military Archives of Poland (Centralne Archiwum Wojskowe) to the scientifi c narrative. These documents are a unique source for presenting general trends of activity of the Ukrainian Military Mission in Poland (May – October 1920). The research methodology is based on adherence to the principles of historicism, anthropology, civilizational, synergic, and systematic approaches along with the usage of analysis and synthesis methods as well as comparative methodology. The scientifi c novelty lies in the unique source value of the aforementioned documents that contain a considerable number of references on the Ukrainian People's Army foremen and military offi cials' surnames who arrived in Warsaw due to various means of offi cial business. In addition, the orders captured information about multiple business trips, sometimes along with mentioning their purpose and travel destination. In certain circumstances, the orders of the Mission reconstruct fragments (or the entirety) of the Ukrainian People's Army higher military institutions' instructions. Conclusions. The analysis of orders undertaken within this article shows that, throughout its whole existence, the Ukrainian Military Mission implemented an enormous amount of work which preeminently was based on maintaining personnel replacement of the Ukrainian People's Army. Simultaneously, its members undertook all necessary efforts to organize weapon supply for the Ukrainian People's Army which resulted in the set of discussions with interested powers among the governmental representatives of the European states and business circles. The activity of the Ukrainian Military Mission has become one of the most vivid episodes of the joint Polish-Ukrainian military cooperation in the 1920s-1930s that provided the best examples of uniting together efforts of two countries – Poland and Ukraine – in front of deadly danger from Bolshevik Russia. The whole period of Mission's existence was marked by its remaining as a central communication detachment between the military establishments and armed services of two states that led to the formation of a majority of Polish military representatives who positively perceive the Ukrainian People's Army and its combat potential.
